Although his admiration for the British philosophical tradition is widely recognised, Brentano’s antipathy to classical German philosophy is no less well-known. That Brentano may be at all committed to the construction of a grand system in the tradition of Kant or Hegel seems to run contrary to the most basic wisdom regarding this pivotal figure in the history of the phenomenological movement, and several of his most well-regarded interpreters have explicitly rejected any suggestion that he might helpfully be understood as a systematic philosopher. This, however, is precisely the claim which Uriah Kriegel defends with such force and clarity in his impressive study, Brentano’s Philosophical System: Mind, Being, Value. According to Kriegel, Brentano ranks amongst the greatest systematic philosophers of the Western tradition, offering a comprehensive account of the true, the good, and the beautiful, ultimately grounded in an understanding of the modes of consciousness which facilitate the mental representation of these ideals.
In spite of his systematic aspirations, however, Brentano’s philosophical style bears closer comparison to the analytic tradition than to the works of Kant and his idealist successors, according to Kriegel. Indeed, Brentano is, for Kriegel, a kind of analytic philosopher avant la lettre, whose concerns and priorities belong not to an outmoded nineteenth-century agenda, but to the domain of contemporary philosophy. There remains, however, a sense in which Brentano has less in common with analytic philosophy than with its nineteenth century predecessors, insofar as his focus is very firmly upon consciousness rather than language as the principal object of philosophical investigation. Brentano does not participate in the linguistic turn which is partly constitutive of the switch from idealist to analytic philosophy, and his focus on consciousness is an enormous part of his legacy to later phenomenologists (with the possible exception of Heidegger and his followers). This is, however, something of a pedantic objection, and Kriegel leaves little doubt that Brentano’s philosophical style is one which should make his work accessible to contemporary analytic philosophers. Across nine well-argued and engaging chapters, Kriegel elucidates Brentano’s compelling and highly original contributions to philosophy of mind, metametaphysics, metaethics, normative ethics and other fields of current philosophical interest, repeatedly showing that Brentano merits a place in contemporary debates within each of these thriving areas. As such, Kriegel’s study should be of interest not only to scholars of Brentano and early phenomenology, but also to researchers in several areas of contemporary analytic philosophy.
Part One, ‘Mind’, opens with a chapter on ‘Consciousness’. For Kriegel, Brentano’s interest in consciousness is an interest in what today’s philosophers of mind call ‘phenomenal consciousness’ – its felt qualitative character. As such, many of Brentano’s remarks concerning consciousness rest ultimately upon appeals to phenomena with which it is assumed that all subjects are immediately acquainted insofar as they are conscious at all. According to what Kriegel calls Brentano’s ‘awareness principle’, one cannot be conscious without being conscious of being conscious. Such awareness of one’s own mental states is the source, Brentano maintains, of immediate and infallible self-knowledge resulting from what he famously labels as ‘inner perception’ and distinguishes from introspection or ‘inner observation’.
In an impressive display of scholarly engagement with the relevant primary and secondary literature, Kriegel advocates a novel and compelling interpretation of Brentano’s position, according to which the same mental state may be viewed either as the ‘consciousness of x’ or as the ‘consciousness of the consciousness of x’. As such, inner perception owes its unique epistemic merits to the identity between (i) a conscious state and (ii) the consciousness of that very state. Kriegel clearly distinguishes his interpretation from those offered by other Brentano scholars, such as Textor. Moreover, Kriegel credits Brentano with a position which he argues is more compelling than many modern theories of consciousness, such that Brentano’s approach is of more than merely historical interest.
Kriegel also notes however, the implausibility of Brentano’s commitment to the co-extensionality of mental states and conscious states. As he aims to show throughout the remaining chapters however, this is a position which may be excised from Brentano’s system with minimal repercussions. All the same, Kriegel maintains, it is important to note that Brentano’s philosophy of mind is, for this reason, more properly a philosophy of consciousness.
In Chapter Two, ‘Intentionality’, Kriegel advances an original interpretation of the concept with which Brentano’s name is most associated. Parting company with widely-held ‘immanentist’ interpretations, such as Crane’s, Kriegel denies that Brentano understands intentionality as a relation between a mental act and a subjective content internal to that act. Indeed, according to Kriegel’s ‘subjectist’ interpretation, intentionality is not, for Brentano, a relation at all, but a modification of the subject. Their misleading surface grammar notwithstanding, sentences appearing to commit one to the existence of a relation between a conscious state and an object thereof are more accurately understood as statements concerning a condition of the subject, according to Kriegel. As he interprets Brentano, non-veridical experiences have no intentional object at all, Kriegel maintains, rather than a merely private intentional object. To think of dragons, then, is not to be related to a fictitious object but to inhabit a state of a certain kind. By the same token, it is not constitutive of one’s thinking about the Eiffel Tower that it is indeed the intentional object of such a mental state. All that matters, in either case, according to Kriegel, is that the subject occupies such a state that, were certain conditions to be satisfied, that state would have an intentional object. Talk of ‘merely intentional objects’ is, as Kriegel understands Brentano, admissible only as a convenient fiction, as shorthand for the unsatisfied veridicality-conditions of some mental state.
While it is distinct from adverbialism, according to Kriegel, the position thus attributed to Brentano may, he acknowledges, appear vulnerable to an objection similar to that which Moran raises against the adverbialist. The last part of the chapter offers an answer to this revised criticism, showing again that Brentano’s views remain plausible. Kriegel proceeds with clarity and precision throughout in recognisably analytical fashion.
Chapter Three concludes Part One with a detailed account of Brentano’s taxonomy of the various kinds of conscious states. As Kriegel notes, Brentano’s interest in the systematic classification of mental states – and its centrality to his philosophical project – is characteristic of the taxonomically-fixated nineteenth century, but seems quite foreign to the priorities of contemporary philosophers of mind in the analytic tradition. Kriegel further remarks that Brentano is in disagreement with late twentieth and early twenty-first century orthodoxies in consequence of his anti-functionalist classification of mental states according to attitudinal properties rather than inferential role. Related to such anti-functionalism is Brentano’s notorious claim that disbelief-that-p is not equivalent to belief that not-p – a position starkly opposed to Frege’s.
All the same, Kriegel maintains, Brentano’s philosophy of mind loses much of its unfamiliar appearance when the scope of its claims are limited to the domain of the conscious, whereupon they become compatible with a broader functionalist outlook. With slight qualifications, Brenatano’s foundational distinction between judgement and interest may be understood to correspond to a familiar distinction between mental states, on the one hand, with a mind-to-world direction of fit and those, on the other, with a world-to-mind direction of fit. Brentano treats the distinction between propositional and non-propositional content as of secondary importance, however, and Kriegel takes it that there is nothing in contemporary classifications of the mental corresponding to Brentano’s treatment of presentation as a category of phenomena no less fundamental than judgement or interest. Much of chapter three is devoted to a reconstruction and defence of Brentano’s commitment to such an account of presentation – a position which Kriegel regards as persuasive and correct, but detachable from the rest of the Brentantian system without need for significant revisions elsewhere. Judgement and interest, however, remain of crucial systematic importance, according to Kriegel.
The second part of Kriegel’s fascinating and well-argued study concerns Brentano’s metaphysics, opening with a chapter on ‘Judgement’. As Kriegel re-iterates, Brentano’s account of judgement differs radically from more familiar theories in several respects. Firstly, no judgement is ever merely predicative, according to Brentano, but every judgement either affirms or denies something’s existence. Secondly, affirmative and negative judgements differ not in content but in attitude, and are therefore able to share the same content. Thirdly, the content of any judgement is always some putative individual object, rather than a proposition or state of affairs. In spite of its remarkable heterodoxy, however, Kriegel judges that Brentano’s account is astonishingly compelling and can be defended against several possible objections while facilitating a nominalistic ontology which is likely to appeal to current trends of metaphysical opinion. Kriegel ably and methodically proceeds to assess the prospects for Brentanian paraphrases for various forms of judgement, aiming in each case to show whether that judgement is reducible to an affirmation or denial of some particular object’s existence. In most cases, Kriegel maintains, adequate paraphrases are indeed available, although he expresses some doubt that such paraphrases accurately match the phenomenology involved in judgements of that kind. According to Kriegel, the best available Brentanian paraphrase of the negative compound judgement “~ (p & q)” would be something along the lines of “there does not exist any sum of a correct belief in p and a correct belief in q”. While respecting the strictures of Brentano’s theory of judgement, Kriegel maintains, such a conceptually elaborate paraphrase – which involves second-order beliefs – is questionable as a description of the conscious experience involved in the judgement, “~ (p & q)”: a potential shortcoming in a theory alleged to rest upon no other foundation than the accurate description of immediately accessible conscious states.
Brentano’s metaontology – his account of what one does when one commits to the existence of something – provides the focus for Chapter Five. After summarising what he takes to be the three most prominent approaches in contemporary metaontology – those which he attributes to Meinong, Frege, and Williamson – Kriegel proceeds to distinguish Brentano’s position from each of these. Unlike any of the more familiar positions, Brentanto’s holds that nothing is predicated of anything – whether a subject or a first-order property – when something is said to exist. Rather, to say that something exists is to say that it is a fitting object of a certain kind of mental attitude – that of belief-in, or affirmative judgement. To say that x is a fitting object of belief-in, moreover, is to say that were a subject capable of deciding the matter on the basis of self-evidence then the attitude they would take to x would be one of belief-in. In view of serious problems attending Brentano’s analysis of belief-fittingness in terms of hypothetical self-evidence, however, Kriegel offers the revisionary proposal that belief-fittingness be understood as no less primitive than self-evidence. Belief-fittingness would be unanalysable in that case, although particular instances of belief-fittingness would be distinguishable by comparison against contrasting cases.
It is, for Kriegel, a liability of Brentano’s position that, by interpreting existence-statements as disguised normative claims, it fails to accommodate the phenomenology of such judgements, which do not seem at all, to those who make them, like statements about the mental attitude appropriate to one or another intentional object. Nonetheless, Kriegel maintains, Brentano’s position impressively circumvents a host of problems which have confronted the three most familiar metaontological approaches, and is entirely unburdened by any implicit commitment to objects which lack the property of existence without failing to qualify as beings of another exotic variety.
Brentano’s unorthodox theory of judgement and metaontology are largely motivated by a strong aversion to abstract entities, and it is to the nominalistic upshot of these Brentanian innovations that Kriegel turns his attention in chapter six. As Kriegel explains, however, Brentano’s ‘reism’ is quite unlike familiar ‘ostrich’ and ‘paraphrase’ forms of nominalism and is not vulnerable to the kinds of objection which have often been raised against such positions. As a form of ‘strict’ nominalism, it is not only abstracta which Brentano’s position rejects, but also universals, such that the Brentanian ontology condones no other entities than concrete particulars. The truth-maker for “Beyoncé is famous”, to take one of Kriegel’s own examples, is not a proposition or state of affairs, but the concrete particular “famous-Beyoncé”. “Famous-Beyoncé” is a curious entity, however, being co-located with a host of other complex concrete particulars, each of which makes true a certain statement about one and the same Beyoncé to which they are related as accidents of a substance.
Kriegel readily acknowledges, however, that a number of counter-intuitive commitments result from Brentano’s ‘coincidence model’. While recognising Beyoncé as a proper part of Famous-Beyoncé, Brentano is unwilling to risk the admission of abstract entities into his ontology by permitting Famous-Beyoncé to consist of any other proper part than Beyoncé. Although he thereby avoids any commitment to an abstract ‘fame’ supplement, the addition of which to Beyoncé results in Famous-Beyoncé, Brentano is also driven to the odd result that Beyoncé is a proper part without need of supplementation by any further part – a conclusion firmly at odds with the principles of classical mereology. In spite of its shortcomings, however, Brentano’s reism is, according to Kriegel, at least as plausible as any of the nominalist positions currently available, and provides a novel response to the truth-maker challenge.
With Part Three, ‘Value’, Kriegel turns his attention to Brentano’s much-overlooked account of the good. Chapter Seven offers an inventory of the main forms of interest – that basic genre of conscious states, all of the species of which present their objects as either good or bad in some way. Much as Brentano’s metaphysics rests upon his analysis of judgement, so does his theory of value bear a similar relation to his account of interest in its various forms – such as emotion, volition, and pleasure/displeasure. Because Brentano did not complete the projected Book V of his Psychology, in which he had intended to focus on interest in general, several of Kriegel’s proposals in this chapter are offered as ‘Brentanian in spirit’ and Kriegel is forthcoming in appealing to various scattered primary texts in supporting an interpretation of Brentano which he admits may seem anachronistic in its terminology and dialectical agenda.
All the same, Kriegel persuasively shows that Brentano’s works provide the resources for a distinction between will and emotion which respects their common evaluative-attitudinal status. Kriegel develops Brentano’s somewhat sketchy distinction between interests in compatible and incompatible goods by distinguishing between presenting-as-prima-facie-good and presenting-as-ultima-facie-good. Before deciding between incompatible alternatives, both might be emotionally presented as similarly good or bad, but one cannot rationally have incompatible alternatives as an object of volition. Volition differs from emotion, therefore, by presenting its object as ultima facie good, to the exclusion of objects with which it is incompatible. Although he does not suppose that Brentano would draw the distinction in such a fashion, Kriegel also maintains that pleasure and displeasure may be distinguished from emotions in a Brentanian spirit by treating algedonic states as presenting-as-immediately-present some good or ill, whereas emotions do not distinguish, in the presentation of an object, between present and absent goods.
Proceeding in chapter eight to an account of Brentano’s metaethics, Kriegel argues that Brentano may qualify as the original fitting attitude theorist. To call something ‘good’, according to Brentano, is to say that it is fitting to adopt a pro-attitude towards that thing. As such, the good is to interest, for Brentano, as the true is to judgement. The analogue for self-evidence, with respect to interest, is what Kriegel terms ‘self-imposition’ – a feature of those positive or negative value-assessments which irresistibly command our agreement, and which is directly available to inner perception. Those interests are fitting, Brentano maintains, which are either self-imposing or which would be given in inner perception to any subject with a self-imposing attitude towards the intentional object in question.
While highlighting the originality of Brentano’s metaethics – which he claims to anticipate Moore’s celebrated open question argument in certain important respects – Kriegel views self-imposition as a liability for Brentano, inasmuch as it is tasked with both normative and psychological-descriptive functions. For Kriegel, Brentano’s metaethics is an unstable combination of naturalist and non-naturalist features. Nonetheless, Kriegel shows Brentano to argue compellingly against a number of rival accounts and to circumvent certain difficulties which confront such competitors. What is more, Kriegel helpfully locates Brentano’s metaethics within a wider systematic context, returning throughout to parallels between his fitting attitude accounts of judgement and interest. Brentano’s aesthetics, or theory of beauty, is also seen to occupy a location within the same system and to involve a ‘fitting delight’ account, according to which that is beautiful the contemplation of which is itself the fitting object of a pro-attitude. The beautiful is therefore a species of the good, as Kriegel understands Brentano, and is distinct from moral value insofar as it involves the adoption of a pro-attitude towards the contemplation of a presentation.
With the ninth and final chapter, Kriegel turns his focus to Brentano’s normative ethics. Brentano is shown to advocate a pluralistic consequentialism which recognises four intrinsic goods: consciousness, pleasure, knowledge, and fitting attitudes. Whatever is instrumentally valuable in promoting the realisation of these intrinsic goods is therefore of derivative value, according to Brentano, and the right course of action to pursue in any given situation is that from which the greatest good shall result. Although he admits pleasure as an unconditional good – irrespective of its source – Brentano avoids certain counter-intuitive implications of cruder consequentialist positions by acknowledging fitting attitudes as further intrinsic goods. As such, Brentano can admit painful feelings of guilt at one’s own wrongdoing as being of intrinsic value. Whereas, however, Kantians can deny that there is any value in a pleasure derived from wrongdoing, this option is not open to Brentano, for whom the issue of weighing the various goods against one another therefore becomes especially pressing.
Kriegel takes Brentano to face a challenge here, however, and expresses concern that Brentano’s ethics may be unhelpful as a guide to moral action. Having highlighted, in the previous chapter, certain difficulties confronting the notion of self-imposition, Kriegel notes that it is to this same concept that Brentano appeals in attempting to distinguish between which of any two goods is preferable to the other. The fitting preference in any such case is that which the subject would take were their attitude self-imposing, but Kriegel argues that for most such comparisons this moral equivalent of self-evidence will presuppose a measure of knowledge unavailable to any recognisably human agent. As Kriegel observes, it is of little use to advise someone to act as they would were they endowed with perfect impartiality and all of the facts relevant to the case in question.
There is much to recommend Kriegel’s ambitious and scholarly text, which certainly achieves its stated task of demonstrating Brentano’s relevance for contemporary debates across several fields of analytic philosophy. Kriegel impressively avoids the dual perils which confront the historian of philosophy, by locating Brentano’s original contributions within their historical context without, however, denying their relevance to today’s debates. Kriegel perhaps sails uncomfortably close, for some tastes, to an anachronistic reading of Brentano’s arguments and commitments, by phrasing these in terms of a conceptual vocabulary which owes much to late Twentieth and early Twenty-First Century analytic philosophy. Kriegel is forthcoming, however, in admitting his departures from the letter of the relevant Brentanian texts in order to facilitate comparisons between Brentano’s positions and those of more contemporary analytic philosophers. Kriegel also admits to contributing ‘Brentanian’ theses of his own where necessary, in order to fill certain gaps in Brentano’s system or to accommodate objections which Brentano did not anticipate. As such, Kriegel’s account is explicitly revisionary in certain places, such as his recommendations concerning the nature of ‘fittingness’ and his proposals concerning a Brentanian aesthetics. At no point, however, does Kriegel depart significantly from Brentano’s stated position without having already clearly motivated the appeal of a broadly Brentanian contribution to some on-going philosophical debate.
If Kriegel’s Brentano is too much the analytic philosopher for some historians of the phenomenological movement then no doubt he is too much of a system-builder for others. As Kriegel recognises, Brentano’s works are not typically regarded as contributions to a systematic philosophical enterprise, and much of Kriegel’s effort is devoted to correcting this oversight. Here too, Kriegel admits to making ‘Brentanian’ contributions of his own in order to clarify possible links between different parts of Brentano’s system and to provide possible details for areas which Brentano himself left only in outline sketches. That Brentano’s various contributions to ontology, metametaphysics, metaethics, normative ethics and other fields merit interpretation as parts of an overarching system is left in no doubt, however, and this would be sufficient achievement for Kriegel’s impressive monograph, were it not also to highlight the originality and insight which Brentano brought to each of these fields. Most importantly, however, Kriegel admirably shows Brentano’s work to deserve the attention of researchers in several areas of philosophical research, and to reward careful study not only by historians of philosophy and scholars of phenomenology, but also contemporary analytic philosophers.
A Guide to Kant’s Psychologism (2019) is presented as a more accessible and to-the-point delivery of the interpretive theses Waxman lays out in Kant’s Model of the Mind (1991), Kant and the Empiricists: Understanding Understanding (2005), and Kant’s Anatomy of the Intelligent Mind (2014). This comparatively compact 351-page book promises a unique angle on Kant’s theoretical philosophy for a range of philosophical and scientific audiences. The work is original both in its iconoclastic style and its thesis, which defends Kant’s ‘psychologism’ and interprets the titular empiricist philosophers as precursors thereof. Kant’s account of objective representation in terms of the interrelations between sensation, pure intuition, logic and concepts is argued to be firmly rooted in problems brought into the spotlight by the empiricists, such as animal consciousness and multimodal sensory perception. The book thus combines a historical sensitivity to the genealogy of Kant’s philosophy with the systematic ambition of a new interpretation, not merely of one isolated aspect of Kantian theory of mind but of the way its various doctrines fit together, from pure intuition to apperception to judgment.
The book is organized into two parts. After an introductory chapter preparing the reader for a radical departure from what Waxman presents as an anti-psychologistic consensus in Kant interpretation, Chapters 2-4 chronologically introduce key thinkers from the empiricist tradition and their contributions to the book’s central concept of psychologism. In chapter 5, Waxman uses Wittgenstein to illustrate Hume’s conventionalism, which in Waxman’s view Kant targets no less than rationalist platonism. Chapters 6-10 guide the reader through Kant’s theoretical philosophy. The sequence of chapters, “The Kantian Cogito” (6), “The Logical I” (7), “The Aesthetic I” (8), “The Objective I” (9), and “The I of Nature” (10) is prescribed less by the text of the Critique of Pure Reason than by the conceptual layers of Waxman’s reconstruction. While regularly referring Kant’s insights back to their empiricist lineage, the progression from the ‘I think’ to the objectivity of physical nature also points to Cartesian and Leibnizian influences in Kant’s treatment of logical universality. The chapters on Kant additionally argue that the doctrines of pure intuition and logical form, interpreted as elements of an ‘a priori psychologism’, can accommodate post-Kantian scientific developments in logic, geometry, mathematics and physics. The concluding chapter assesses platonism and conventionalism as the only possible routes of refutation of Kant’s psychologism, as well as indicating how Waxman’s interpretation may be illuminating for contemporary study of the mind.
One of the most original features of the book is that it makes the compatibility of Kantian doctrines with subsequent scientific advances a matter of first importance: “naturalistic theories like Kant’s and those developed by his British empiricist forebears were intentionally crafted to leave open a place for future science on which philosophy can never impinge” (12). The scope of the book is not only to radically overhaul received opinion on Kant’s methodology, and the relation of his ideas to the sciences, but to defend a biologically plausible version of Kant’s account of logical form. In the remainder of this review I will address in turn: (1) Waxman’s definition of ‘psychologism’ and how his use of this concept situates him with regard to other interpreters; (2) his reading of Kant, with a focus on the logical forms of judgment according to the psychologistic approach; and (3) some questions emerging at the interface of Waxman’s naturalistic reading of Kant and the sciences, especially neuroscience and evolutionary biology.
Waxman stresses that Kant’s ability to resolve skepticism about the objective purport of (some of) our representations is rooted in his radicalization of the British empiricists’ methods to accommodate logical universality, modality, and relational concepts. Thus, the book’s overarching thesis about the relationship between its titular figures is that Kant continues what Locke, Berkeley and Hume started, expressed as their common adherence to psychologism. Waxman has in mind a quite specific interpretation of this term:
[T]he task of psychologism is to explicate meanings, with special emphasis on identifying psychological ingredients essential to notions that, in language, are free of any tincture of psychological content. There can therefore be no expectation that the psychological contents adduced as essential to the meaning of familiar notions will themselves be familiar. (147)
Waxman’s compelling take on the psychologistic philosopher’s undermining of rationalist metaphysics is thus that psychologistic elucidation makes us distrust the appearances of the natural language of metaphysics, thereby overturning realist intuitions that the qualities we discern in appearances are properties of mind-independent objects (33f). Psychologism in this sense, Waxman is clear, is not to be confused with the fallacy of explicating the non-psychological psychologically (305). According to Waxman’s use of the term, psychologism means giving contents which are in fact psychological their due explication in terms of mental representations. Kant’s account of how we are capable of “cognitive representation of sense-divide transcending external objects” (264) equips empirical psychologism with the resources to explicate the objectivity and logical universality of our representations, where this is possible. Hence, “any representational content that neither empirical psychologism nor conventionalism can explicate, a priori psychologism can, and what the latter cannot explicate, nothing can” (147).
Waxman introduces his interpretation as a novel defence of Kant’s theoretical philosophy which rejects two pervasive trends in its reception: an anti-psychologistic consensus, and a more general obsolescence consensus that due to revolutions in logic, geometry, and physics, Kant’s philosophy is “a once formidable structure long since reduced to ruin, fit only for piecemeal salvage” (24ff). The latter engenders attempts to clear the respectable theory behind Kant’s project of its psychologistic methods, resulting in a range of approaches to ‘updating Kant’ e.g. by explaining conscious representation using anything from post-Fregean mathematical logic to Chomskyian linguistics, or Roger Penrose’s quantum theory of consciousness (15). Against these kinds of salvage attempts, Waxman argues that a properly psychologistic account of Kant’s theory of objective representation reveals its compatibility with subsequent developments in logic, geometry, physics, as well as neuroscience and evolutionary biology.
Kant scholars may suspect that the anti-psychologistic consensus is by no means universal: for instance, Andrew Brook’s Kant and the Mind (1994), and Patricia Kitcher’s Kant’s Transcendental Psychology (1990) (see also Falkenstein and Easton 1997) make similar critical points about the anachronism of understanding Kantian theory of cognition ‘anti-psychologistically’. For example, “Kant clearly held that his ‘logic’ of the mind is part of what we would now call psychology” (Brook 1994, 6). Waxman takes note of these authors in a footnote, nonetheless signalling his substantive interpretive differences from Kitcher and Brook as well as Lorne Falkenstein and Scott Edgar. The problem, Waxman explains, is that these authors refer to ‘psychology’, which is concerned with “whether and how a representation comes to be in us (empirically, innately, etc.)” rather than ‘psychologism’, which is concerned with “how the representation itself comes to be” (17n). This distinction, in my view, is not as straightforward as Waxman needs it to be in order to distance himself from other interpreters as far as he claims to.
Waxman himself says in the aforementioned footnote that he agrees with Beatrice Longuenesse’s (1998) work on Kant in its essentials, despite her not using the term psychologism (16). This fosters doubts about exactly what defines Waxman’s psychologism as an interpretive approach. If we stipulate that an anti-psychologistic reading foregoes any reference to mental activity in explicating the meanings of objective representations, psychologistic approaches still come in stronger and weaker flavours, which come down to how the genesis of “the representation itself” is construed.
If ‘psychological’ is interpreted weakly, any view that endorses Kant’s references to mental activities such as synthesis and apperception as non-negotiable parts of the story about objective representation, not wholly translatable into an analytic argument, is “identifying psychological ingredients” (147) in discourse which does not overtly suggest them. I believe most interpreters today would uphold this kind of psychological account. Any particular view on what informs Kant’s psychology need not be empiricist in orientation, as one may instead emphasize the scholastic heritage of Kant’s references to mental acts (e.g. Sellars 1967). On stronger versions, e.g. Kitcher (1990), Kant’s ‘psychologism’ qua account of the genesis of objective representations is a ‘proto-cognitivist’ theory which can be re-formulated in light of contemporary experimental methods and results. Waxman’s qualifies as a weakly psychologistic interpretation, in my view, since nowhere in the book does ‘psychologism’ imply ‘experimental psychology’. In the first chapter and the conclusion, Waxman seems to reject mainly Neo-Kantian attempts to place Kant in the service of twentieth century analytic semantics, philosophy of mind and epistemology—explicitly confronting Strawson (1966) in the conclusion (306), but probably also thinking of authors such as Evans (1982) McDowell (1994), and Cassam (1997). However, they present their work as critical reconstructions and selective adaptations of Kantian ideas. Given that Waxman accuses Strawson’s interpretation of Kant of reverting to a kind of platonism, it would have been interesting to hear more about where Waxman agrees and disagrees with existing criticisms of these Neo-Kantian projects, including McDowell’s (1994) ‘naturalized platonism’.
Let us consider the specifics of Waxman’s use of the term ‘psychologism’. Psychologism is presented as a mode of conceptual explication concerned with the psychological content of the meanings of traditionally metaphysical notions, rather than the psychological mechanisms underlying conceptual meanings. Consciousness turns out to be the key ‘psychological ingredient’ reference to which constitutes a psychologistic account. Waxman stresses that all representation requires some degree of consciousness, but that for Kant and his predecessors consciousness is graded from ‘dark’ to ‘bright’ to ‘clear’ (41) and is hence ubiquitous, reaching down to the sensory representations of basic organisms such as molluscs. Another notable feature of Waxman’s psychologism is its gloss on the normative dimension of Kant’s inquiry into our transcendental justification for applying concepts:
instead of proceeding by defining notions in terms of other notions without regard to whether there is, or even can be, any corresponding conscious representation, psychologism [has] the express aim of seeking out such representations. If the search reveals that a notion owes none of the contents indispensable to its meaning to consciousness, then its scope of application is nowhere limited by it (10).
Conversely, if the notion “can be shown to be beholden to consciousness for any of the ingredients essential to its meaning—ingredients at least implicit, but often explicit, in definitions—then its scope of application is limited accordingly” (10).
In general, the distinctiveness of Waxman’s approach lies in his wholesale engagement with Kant’s more unwieldy terms and concepts, and readiness to endorse Kant’s claims as literally about psychological reality—rather than about concepts, the brain/organism, or the objective world. Despite his psychologistic approach having a foot in psychology and a foot in explication, Waxman is content neither with purely conceptual or exegetical arguments, nor ‘proto-cognitivist’ claims that Kant anticipated cognitive science on this or that front. But he ultimately agrees with many other interpreters that any staunchly ‘anti-psychologistic’ reading is a non-starter, as well as joining Kitcher (1990) and Brook (1994) in thinking that a naturalistic perspective on Kant may be able to contribute to contemporary (experimental) psychology and theory of mind.
I now turn to Waxman’s reading of Kant and his empiricist forerunners. Chapter 2 argues that Locke sets the stage for the psychologistic approach by conceiving consciousness on a scale starting with primitive animals: “Since in the entire absence of sensation no consciousness of any kind seems possible … its terrestrial advent would presumably have coincided with the appearance of the first sensation” (54). In Chapter 3, Berkeley is credited with “extending imagination into the cognitive sphere, thereby for the first time crossing the line separating reality from fiction (where Hume and Kant would follow). This is because the ability to represent space as transcending the divide between sight and touch is indispensable to all cognition of the physical” (85). For Kant, this consideration leads to the thesis that there is nothing in sensation (visual or tactual) that is intrinsically spatial, so the representation of space must be constructed in pure intuition (201). Chapter 4 links the foregoing to Hume’s well-known skeptical challenges to relational concepts:
By shifting the basis of belief in relations from objective experience to subjective feeling, Hume moved the topic from epistemology to psychology where, instead of needing to be justified by evidence and to follow as a conclusion from premises, belief is determined purely affectively, by association-constituting feeling, and nothing else (96).
For Waxman, Hume was the first to psychologistically attribute fully general concepts such as the uniformity of nature and the general causal maxim to humans and non-human animals alike (114). Waxman illustrates the theoretical development from associationism to Kantian a priori psychologism in terms of a speculative evolutionary development from a creature
capable of the kind of highly sophisticated, behaviourally efficacious conscious mentation that Berkeley and Hume devised their associationist psychology to explain. Thanks to some fortuitous mutation or other alteration in its genome, its progeny included creatures capable of the representation ‘I think.’ Having no evident selective advantage by itself, this neural capacity presumably could have established itself in the population only as a spandrel piggy-backing on some genetically connected trait that earned its evolutionary keep. (177)
Eventually enabling complex propositions and inferences, Waxman contends, the ‘I-think’ representation would have enabled behaviours with adaptive value. This evolutionary story complements Waxman’s interpretation of Kant’s logical forms of judgment as more basic than language and indeed making language possible:
The ability of linguistic propositions to blend with non-linguistic is, in its way, no less amazing than the mathematizability of nature. But isn’t this exactly what we should expect if language was originally crafted by creatures already fully conversant in the use of non-linguistic propositional representation, transcendental judgments included? (315).
The chapters of Part II centre around Kant’s psychologization of logic in relation to sensory and propositional representation. Waxman details how Kant adapts from Descartes the contentless representation ‘I think’, which “in and of itself, has no content [and hence] cannot be suspected of having borrowed any, whether from language or anywhere else” (158). Being non-linguistic, it is not attributable to convention and thus provides a purely psychological basis for logical generality that synthetically unifies all possible representable contents (174). According to this notion of pure apperception, Waxman argues that Kantian logic is based in a universal self-consciousness which includes “the totality of logical structures universals enable us to form—propositions, inferences, narratives, et al.” (149). Unfortunately, Waxman doesn’t elaborate on whether self-consciousness is for Kant always a form of ‘bright consciousness’, or could exist in ‘darker’ shades as he argues it does for Hume (120).
Kant brings what Waxman calls “intelligence”—which amounts to consciousness of universality and modality—to Humean representations of general relational concepts which lack any awareness of the “logical universe of possible representations” (171). Kantian concepts “enable us to consciously represent each and every associative combination as a grouping of denizens of the logical universe that are thereafter sortable not only by their sensible/imaginable properties but by their logical ones as well” (171). According to Waxman, Kant’s logical forms of judgment are what “make any ‘I think’-generated concept combinable with any other such concept in a single act of thought, or propositional representation” (167). Conceptual representation is thus explicated as the gradual elimination of degrees of “logical freedom” (150) by restricting the space of logical possibilities to what is representable given the content supplied by sensation and association.
According to Kant’s psychologization of logic, fixing the position of a term as subject or as predicate in a categorical judgment is a psychological act starting with the bifurcation of the logical universe (170). However, such a “logical form by itself cannot guarantee that a proposition will result. In particular, even if a would-be proposition is logically well formed, it would still fail to be a genuine proposition if, for other than strictly formal logical reasons, it cannot be thought without generating not just falsehood but one or another species of impossibility, e.g. … ‘water is not always H2O’” (175). For Waxman’s Kant, categorical form permits the unification of concepts in a single consciousness, but it does not allow a unified representation of the resulting propositions (175). In addition to the assertoric modality, then, we need Kant’s problematic modality, which asserts merely the relation between two propositions, suspending judgment on the propositions themselves. The logical form this assumes in us, hypothetical judgment, relates problematic propositions as ground to consequent in the assertoric modality. Together, hypothetical and categorical forms enable any combination of the totality of possible propositions to be unified in a single conscious act (175f).
Waxman mobilizes this account to show that Kant (1) does not restrict intelligence to language-using organisms, nor (2) does he impose our parochial linguistic structures on his model of the basic “building blocks of propositional thought” (22). Waxman takes his elucidation of Kant’s transcendental logic to counter both misconceptions:
Intelligence can be accorded to any creature, actual or possible, that is capable of pure apperception … even including beings so asocial as to be devoid of anything remotely analogous to language or socially grounded symbolic communication of any kind. This is not to deny that Kant regarded all non-human animals known to him as incapable of apperception and therefore unintelligent. (172)
But, Waxman adds, “that does not mean he would have persisted in that view had he known what we know today” (172). This is an interesting speculation, implying that animals have some form of awareness of universality and modality—not in Hume’s sense, but in Waxman’s more demanding Kantian sense of apperception—“an a priori logical universe that quite literally encompasses all possible conscious representations” (169). I fully agree that Kant’s logic is non-linguistic, but I want to know more exactly how Waxman understands our present knowledge of animal intelligence such that it could make Kant change his mind on this controversial topic.
Waxman regularly refers to his lengthier engagements with Kant’s first Critique in footnotes. These references will be necessary for scholars seeking to determine Waxman’s position on exegetical debates. Part II succeeds in presenting Kant’s account of logical forms and concepts as centrally relying on consciousness, and hence psychologistic, while emphasizing that propositional representation need not be construed as an evolutionary leap separating humans from other animals. The combination of these theses makes for an original, stimulating addition to works on Kant’s first Critique.
I now have some remarks on the book’s intriguing but somewhat ambivalent references to the sciences. Waxman’s general stance that the insights of Kantian psychologism extend beyond their own scientific and philosophical context is very ambitious, and I’m not sure his case is equally strong for each of the sciences he addresses. Waxman makes a convincing case that non-Euclidean geometries cannot falsify any of Kant’s statements about pure intuition, as the latter pertain to the necessary features of any representation of space, rather than any particular geometry:
the formal intuition of space is not only neither Euclidean nor non-Euclidean but completely indeterminate as regards number, limit, distance, metric, part-whole relationships, and everything else that makes space suitable for properly mathematical representation or objective representation of any kind (208-9).
When it comes to the life sciences, however, Waxman’s perspective is (perhaps inevitably) more in tension with the scientific context Kant was writing in.
Waxman is clearly not neutral on matters of philosophy of consciousness, stating at the outset that consciousness is for his purposes identical in existence to its neural correlates (13-14), but that there is nonetheless a distinct psychological reality (14, 57, 159, 162, 177f). As this commitment is not compared to any alternatives, I am curious as to why he has opted for this particular form of identity theory to defend the biological plausibility of Kant’s psychologism, rather than functionalism or some form of emergentism. Polák and Marvan (2018), for example, defend the view preferred by Waxman that neural correlates are not in a causal relation to conscious states but an identity relation—a position which philosophers of mind might like to see defended more explicitly in connection with Kant’s views. Also, they may ask whether there is a specifically Kantian motivation for understanding the “mystery of consciousness” as Waxman does, that is, “a purely physical existence that is at the same time irreducible to physical reality” (14). Waxman clearly wants a naturalistic position to complement his psychologistic interpretation, but he also does not want to impose too much recent theory on the historical theories. Given this concern, psychophysical parallelism—an early form of identity theory espoused in different (including Neo-Kantian) versions by German philosophers from Fechner to Feigl via Riehl and Schlick—could illuminate Kantian psychologism from this side of Darwin and experimental psychology (see Heidelberger 2004, Ch. 5). Of course, it would be possible for most Kant scholars to profess neutrality with respect to these debates, but Waxman has—to his credit—set different standards.
Waxman’s decision to adhere to Kant’s original terminology and to steer clear of issues of translation in one sense makes the book smoother. The book conveniently contains a glossary, and tailor-made terms such as ‘AUA [analytic unity of apperception] concepts’, and ‘dark consciousness’ helpfully remind us that a term is not being used in its familiar sense. Waxman’s capacious use of ‘consciousness’ clearly works in his favour insofar as Modern and Kantian philosophy become much more relatable simply by lowering the threshold (as we understand it) on what sensory and cognitive states count as conscious. Yet it would have helped for Waxman to illustrate the general features of (what Descartes, Locke and Kant viewed as) ‘dark consciousness’ in more descriptive neural or psychophysical terms—not simply because readers may have difficulty forgetting the current meanings of such terms and the controversies attached to them, but because it would improve the book’s case for making psychologism compatible with contemporary biology.
One of the book’s most interesting features is its rapprochement between Kant and Darwin. Frequent references to phylogeny and the evolutionary plausibility of psychologism (as contrasted with platonism and conventionalism) evidence Waxman’s eagerness to integrate Kant’s insights into a post-Darwinian landscape, which I take to be a very important, relatively neglected project:
[N]ot only is Kant’s psychologism consistent with evolution, it actually spotlights suitably primitive forms of empirical consciousness that would gain adaptational advantages from a priori consciousness. Most basically, formal intuitions can easily be conceived to be of use to minds grappling with the challenge of combining external sensations into a single, unified external sense capable of providing immediate access to sense-divide transcending objects. (306)
This illumination does not go both ways, however, since Waxman also says that transcendental consciousness is entirely outside the scope of scientific explanation (295)—“because the subjectivity constituted by apperception … becomes part of the explanation of the physical, it cannot itself be explained physically on pain of circularity” (23). This claim recalls circularity charges against naturalized epistemology and logic, which in my view can be convincingly refuted by pragmatic and holistic considerations. It also blatantly contradicts the book’s initial claim that “[t]he mental is causally and in every other way fully determined by its physical underpinnings, and so is in principle fully explicable by science” (21). This is surprising, after seeing Waxman go to great lengths to argue that although a priori, the most innovative aspects of Kantian philosophy are features of our natural constitution, different in complexity but not radically different in kind from the sensory sensitivity of an oyster. Placing a priori elements of Kantian psychologism beyond the reach of current and future biological explanation strikes me as a missed opportunity, and again makes me doubt what is meant by psychologism. Empirical research in animals can indicate how consciousness might have arisen, and in a footnote Waxman considers but then discards a few such accounts based on their comparatively restrictive definition of consciousness (63n). The reader may suspect that casting the net more widely would reveal theories more congenial to Waxman’s evolutionary take on subjectivity, such as Godfrey-Smith (2016).
The following passage is a good example of Waxman’s ambivalence towards his own naturalistic outlook:
The connection between the subjective psychological reality of consciousness and the objective physical reality of neurophysiology is a complete mystery in both directions, today and quite possibly for some time to come. Thus, Kantian logical forms of judgment pose no special mystery but instead are best regarded as simply an additional species of phylogeny-dependent neuro-psychological reality in addition to sensations, emotions, dreams, and the rest. (178)
Because Waxman has not restricted himself to purely exegetical argument, or the Kitcherian ‘proto-cognitivist’ angle described earlier, the reader may wonder how literally such claims are to be taken. One cannot but agree that (something similar to) Kantian a priori capacities such as the logical forms of judgment must have evolved somehow, just as there must be some neural correlates for the empiricists’ associative psychologies, as indicated in Part I. But the empirically-minded reader will want to know in more detail how forms of judgment (or their successors in contemporary science of mind) could be modelled and studied, if they are on a par with sensations and emotions.
A Guide to Kant’s Psychologism is bound to appeal to diverse philosophical audiences for its fresh take on Kant’s theoretical philosophy as a priori psychologism. It is also a lively, articulate instance of philosophical storytelling. Waxman avoids approaching Kant through the lens of contemporary philosophical problems where semantics, epistemology and metaphysics are concerned. When it comes to the sciences, however, the book makes us acutely aware of pieces of the puzzle of the mind in nature that Kant simply cannot have anticipated. Kant’s understanding of his current science needs to be confronted with today’s sciences in order to address all of the questions raised by an interpretation of Kantian philosophy as naturalistic a priori psychologism. Over the course of Waxman’s book, frequent references to neural correlates and phylogeny habituate the reader to seeing our biological reality in the same conceptual space as Kantian doctrines, which is surely a step in the right direction. As is perhaps Waxman’s intention, it is left to the reader to ponder the convergences and divergences between Kant’s account of the mind and current scientific knowledge, perhaps especially the life sciences. The book offers its non-Kantian readers a challenging, raw encounter with Kant’s theoretical philosophy, and will leave Kant scholars much to think about both on the old problem of psychologism and new ones arising from Waxman’s brand of naturalism.

The decisive influence of McDowell in shaping the contemporary debate over non-conceptual content is well known. After the release of Mind and World (1994), almost any attempt to assign non-conceptuality to the contents of perception had to engage with McDowell’s conceptualist model of experience. The rich discussions inspired by conceptualism in the current literature on non-conceptual content, however, often ignore the original philosophical motivation behind McDowell’s thesis, or so goes the premise of Van Mazijk’s new book Perception and Reality in Kant, Husserl, and McDowell (2020). This motivation comes from the tradition initiated by Kant in the 18th century, and followed by Husserl in the late 19th, known as transcendental philosophy, whose main idea is to put into question that which is the fundamental presupposition of the sciences, namely the availability of reality to us. The central aim of Van Mazijk’s book is to recover this original transcendental concern of McDowell’s thought by inserting his conceptualism within this broader tradition mainly represented by Kant and Husserl. As a result, it ends up by exploring how Kantian and Husserlian approaches of transcendental problems avoid certain inconsistencies in McDowell’s conceptualism, thus providing better alternatives for understanding the relation between mind and world.
The book is structured in three parts, each containing two chapters dealing with those thinkers’ theories of perception, since perception represents the most basic way through which the world is made available to us. Given the author’s overall aim to offer a new critique of McDowell’s thought, both Kantian and Husserlian theories of perception are analyzed through the lens of the conceptualism debate. This is made possible with the help of the distinction between weak conceptualism and strong conceptualism, which represents the key distinction of the entire book. Weak conceptualism is defined as “the view that all intuition and perception is, for us at least, open to conceptual exercise” (4), and strong conceptualism as the view that “concepts structure sense experience, and this is in fact what first makes reality perceptually available” (4). All the discussions that follow are carried out in view of this important hermeneutical tool.
The book follows historical sequence, thus beginning with Kant and ending with McDowell. The author himself, however, suggests that the chapters could be read independently of one another, and that any reader specifically interested in McDowell and in contemporary philosophy of perception could begin with the two last chapters on McDowell. I would rather suggest that readers not familiar with the contemporary discussion of conceptualism in philosophy of perception do that. This way they will better understand what is mainly at stake in the discussions with Kant and Husserl in the remaining chapters.
The first part focuses on how Kant’s transcendental philosophy provides us the tools to have an immediate access to reality, and not, e.g., an inferential one. The overall purpose is to advocate a weak conceptualist reading of Kant’s theory of perception, in opposition to, for instance, McDowell’s strong conceptualist reading of it. After introducing the basics of Kant’s theory of knowledge in the first chapter, Van Mazijk proceeds, in the second chapter, to the transcendental deduction. An adequate reading of the deduction is essential to a conceptualist interpretation of Kant’s theory. For instance, according to Van Mazijk, McDowell’s reading of the deduction is at the basis of his strong conceptualist interpretation of Kant. The author reads McDowell as stating that Kant places the dependence of sensible intuition on the categories at the same level as the dependence of it on space and time (41). This is a mistake, Van Mazijk’s points out, as the necessity of a transcendental deduction is justified precisely due to the fact that the “pure concepts, in Kant’s view, stand at a certain distance from the world; they are not sine qua non conditions for sensible intuitions in the way space and time are” (40).
Van Mazijk’s analyses of the A and B-Version of the deduction yield basically the same conclusion, namely that Kant is mainly concerned with weak conceptualism, as long as he insists that appearances have to be relatable to a unitary consciousness (which does not compel them to be always necessarily related to a self-consciousness or standing I). Apperception, so goes Van Mazijk in a close reading of Kant, is defined in terms of potentiality: “Apperception, then, need not be understood as a permanent, onlooking I; it is rather itself the potential for the I to be awakened; a transcendental potential for becoming actively aware of what is intuited” (45).
Besides that, however, strong conceptualism seems to also play a role in the deduction, especially in the A-Version. This is due to the synthesis of imagination and its specific role in the openness of intuitions to conceptualization. The main idea seems to be the following: The adequacy of intuitions to pure concepts – what Kant calls their affinity (46) – is the product of the synthesis of imagination. This affinity is already to be found previously in the sensibility itself as an “aptitude” of intuitions to be associable with pure concepts. This means that the contents of sensibility must already have an affinity with the understanding. Now, the synthesis of the imagination, Kant states, is grounded in the categories (46). Therefore, the categories are constitutive of intuitions, which is exactly the strong conceptualist thesis. That is, intuition is open to conceptualization (weak conceptualism) precisely because it is conceptually structured (strong conceptualism). Van Mazijk concludes from this that “pure concepts might after all play an important role in intuition, insofar as they would supply the imagination with the forms of synthesis required to make intuitions open to conceptualization” (47). In the end, however, the greater prominence seems to be given to weak conceptualism: “It can be concluded that, in both versions of the deduction, Kant’s principal aim is to show that pure concepts apply unconditionally to any intuition” (49). With regard to strong conceptualism, Van Mazijk only states that we have “some textual support” (49) for it.
The second part deals with Husserl’s theory of perception and knowledge. The third chapter begins by introducing the basic elements of Husserl’s early theory of intentionality that comes from the Logical Investigations. They are the quality (the way of intending something), the object-reference and the matter (the Fregean sense) of the act (63). Another important element within the intentional structure of consciousness is the sensation content, which Van Mazijk interprets not as unstructured data, but as having some kind of non-intentional and non-conceptual structure (66). Despite being non-conceptual, sensations are not regarded as merely natural facts, and are not, therefore, excluded from the concern of philosophy as a matter of, e.g., physiology, as in Kant’s account.
Nevertheless, sensations do not play any role in Husserl’s account of knowledge as synthesis of fulfillment, as long as they do not have an articulable structure, that is, a propositional structure which can be also instantiated in beliefs. Van Mazijk begins his explanation of Husserl’s theory of fulfillment by stressing that “it is crucial to observe first that, in Husserl’s view, signitive acts alone can be defined as meaning acts” (68). Knowledge is then explained as a coincidence that happens between this empty act of meaning and an appropriate fulfilling act. When I merely entertain the thought of a blackbird in the garden, for instance, I have an empty signitive act of meaning. When I look and see the blackbird, this act of intuition comes into a coincidence with my former signitive act and gives rise to a synthesis of fulfillment (69). Van Mazijk goes on to explore that not only sensible perception can provide fulfillment, but also memory, categorial intuition of ideal states-of-affairs and universal intuition. (69-70). Importantly, the fulfillment does not rely on all the aspects of the act, but only on the intentional ones: “all and only intentional contents come up for fulfillment and allow of propositional articulation” (71). From this, the author concludes that Husserl “clearly defends a version of weak conceptualism” (71). The reason why this conceptualism is weak is because “the articulable content of the fulfilling act (say, a perceptual content) can play its fulfilling part only by virtue of the fact that it is not just a conceptual content” (79). That is, the fulfillment can provide warrant for empty beliefs due to the fact that it makes an extra-conceptual contribution to it.
The clarity with which the theory is presented hides, however, the greatest difficulties of Husserl’s text. There are, for example, some problematic passages in the Logical Investigations where Husserl states that “the very thing that we marked off as the ‘matter’ of meaning, reappeared once more in the corresponding intuition” (Husserl, 2001, 241). This kind of statement seems to challenge the author’s affirmation that “signitive acts alone can be defined as meaning acts” (68), since the “matter” – understood as the Fregean sense and hence as conceptual content – would make both signitive and intuitive acts as carriers of meaning. Another problem not faced by the author is one concerned with the concept of fullness. It is only stated, at the end of the section dealing with fulfillment, that it is the “peculiar character of fullness” that “distinguishes perception (as an intuitive act) from thinking (as an empty act) – instead of, say, a real causal relation to an object” (72). Nothing, however, is said about this peculiarity itself, and the difficulties that are implied by this statement are not deemed important by the author. I find this to be a mistake, since the exact way in which the fullness gives fulfillment is one of the most important and controversial aspects of Husserl’s theory, and its clarification seems to me to be necessary to make understandable the “extra-conceptual contribution intuition makes relative to our empty beliefs” (72) mentioned above. The apparent inconsistencies in Husserl’s description of fulfillment was, by the way, one of the initial motives for the dispute over conceptualism with regard to his theory of perception.
The second half of the third chapter deals with Husserl’s transcendental turn and offers an interesting and original reading of the phenomenological reduction. The reduction should show us that all the sorts of nature-reason divide that somehow sets consciousness apart from the world are in the wrong path. Rather, reason and nature form a whole that could be investigated from the perspective of consciousness (as manifestations in my streaming conscious life) and from the perspective of nature (as real facts in the world). This results in a view the author calls “the double aspect theory” (80), which allows both natural science and philosophy to study the relation between mind and world: the former studies it as a natural fact under a natural attitude, forming a space of nature; the latter as a relation in the streaming of conscious life under a phenomenological attitude, forming a space of consciousness (81).
I find this way of presenting the phenomenological reduction to be one of Van Mazijk’s most interesting contributions that should be explored in the approximations between Husserlian phenomenology and conceptualism. Particularly important is that it understands the space of consciousness as wider than the space of concepts, thus making room for non-conceptual and non-intentional sensations in the philosophical approach of consciousness. For instance, the naturalistic psychology of Husserl’s time tended to see everything that does not have a relation to an apperception as a natural fact. By the same token, McDowell tends to see everything that falls outside the conceptual space of reasons as a natural fact. From Husserl’s perspective, in Van Mazijk’s view, this results from a failure to see that the world is not divided into two separated regions, mind and world, but is rather “one totality of being (mind and world), which can be viewed either under the aspect of nature or that of consciousness” (87). Absolutely everything is encompassed by the space of consciousness, only that under its specific attitude, which is not the same of the natural sciences. There is no reason, therefore, to exclude the non-conceptual and the non-intentional from it.
The fourth chapter turns to Husserl’s later genetic investigations in order to demonstrate how phenomenology can accommodate all accomplishments of consciousness. Van Mazijk proceeds here to the concrete analyses of non-conceptual levels of perception, showing that they are not restricted to empirical investigations, as in Kantian and McDowellian pictures. The chapter exhibits the powerful scope of phenomenology, which ranges from the most basic level of mere sensation to conceptual thought. This is considered by the author “Husserl’s master thought”, namely that “the space of consciousness can be analyzed as a unitary whole” (117), and not only as empty a priori forms of knowledge (Kant) or as conceptual capacities in the space of reasons (McDowell).
The genetic investigations present our openness to the world in a stratified manner. Three levels of perceptual accomplishments as well as three levels of conceptual ones are distinguished by the author. The analysis of these accomplishments provides an occasion for an interesting discussion with McDowell. Husserl is said to obey a strict divide between perceptual and conceptual content (105). Thus, to perceive something as being thus and so and to judge something as being thus and so are two different things, one involving a perceptual content, the other involving a conceptual content. But how do we get from perception to judgment? This is, of course, one of the most important problems of McDowell’s Mind and World, and it is there solved by appealing to strong conceptualism: the conceptual contents determine the perceptual experience. Husserl, in turn, has another story to tell. It is possible to perceive something as being thus and so without forming a judgment about that, that is, it is possible to “perceptually explicate relations between things perceived, yet lacking the ability to attain the propositionally articulated content” (104). Therefore, it is not the judgment that determines perception, but the other way around: it is because we can intentionally (albeit non-conceptually) be related to things in perception, that we can form judgments about them, and not the other way around. In order to make a judgment, “the ego must repeat the passive process, but this time in a changed, active attitude” (105). By doing this, the ego “extracts” the contents of perception and informs them with propositional articulation in judgment.
This narrative is a bit obscured, however, as Husserl speaks of the propositionally structured object being “pre-figured” in perception (105). This paradoxical statement serves to complicate the matters in the attempt to fit Husserl in the conceptualist or non-conceptualist parties. Van Mazijk does not overlook this challenging problem and engages with it in the second half of the chapter by exploring Husserl’s notions of horizonal awareness, motivation and bodily action – which form a “kinesthetic system” (107-110) –, and also his concept of habit (acquired skill) (111-117). Generally speaking, the idea is that perception considered as a simple intentional relation to an object is, on Husserl’s account, an abstraction. It is not a starting point (as it is in almost any theory of perception), but a resulting process. The original genetic analyses provided in this section show that “for us, then, perception is saddled with concepts after all” (118). This, however, in the author’s view, is not enough to assign Husserl a strong conceptualist theory of perception, since “intellectual acts are not a condition of possibility for a rich perceptual intentionality”, and “the fact that (some) perceptual contents are fit to figure in judgments does not derive from a capacity to judge; it is due to perception itself” (p118). Husserl remains, thus, in the end, a weak conceptualist.
The last part of the book focuses on the theory that orients all the discussions of the previous chapters, namely McDowell’s conceptualism. The fifth chapter introduces the central conceptualist claim that the contents of experience are all conceptual and explains how it arises as the only way out of the epistemological dilemma between the myth of the given and coherentism. As is well known, McDowell’s solution is to expand the conceptual domain beyond the mental sphere and to place it in the world, admitting experience to have conceptual content.
Having stated the conceptualist thesis, Van Mazijk goes on to ask some important questions that challenge its overall consistency. The author lists and analyzes 14 fragments from McDowell’s writings in order to find out what exactly does it mean to say that the contents of experience are conceptual. A close and detailed reading of these fragments reveal that McDowell oscillates between a weak and strong conceptualism, but in the long run favours the strong version. Strong conceptualism, in turn, raises the most important issues with respect to the consistency of McDowell’s idea. Particularly, it does not explain which concepts specifically are necessary to inform perceptual experience and leaves unanswered the question of how perception in non-rational animals is possible (since they do not possess concepts) (124-132).
After exploring these inherent difficulties in McDowell’s conceptualism thesis, Van Mazijk goes on to discuss how Kant and Husserl could offer better answers to them. The main purpose is to show that a weak conceptualism “should suffice to establish intuition’s inclusion in the McDowellian space of reasons” (133). That is, since weak conceptualism, either in its Kantian or Husserlian forms, avoids the issues raised above against McDowell’s strong conceptualism, then the former is preferable to the latter. With respect to Kant, the author states that it is at least conceivable that an imagination functioning differently from ours synthesizes intuitional contents in a non-conceptual manner (134). Therefore, it is at least thinkable, in the Kantian framework, to have a non-conceptual relation to the world. As to Husserl, it is said that both the early theory of fulfillment and the genetic investigations of later phenomenology offer good reasons not to account for the contents of perception under the unique category of the conceptual. Both Kantian and Husserlian more detailed distinctions in the realm of perceptual content should then make room for some kinds of nonconceptuality in the contents of perception that do not fall prey to the myth of the given, thus avoiding the necessity of strong conceptualism.
The sixth and final chapter criticizes the most important assumption of McDowell’s conceptualism, namely his division of spaces. In short, this division amounts to two ways of dealing with things: as natural lawful phenomena (the space of nature) or as rationally relevant exercises (the space of reasons). Van Mazijk proceeds to analyse how McDowell, in order to avoid any threat of non-naturalism, allows everything else but conceptual contents to be placed within the space of nature. This generates several problems. Among them, it makes it impossible for McDowell to give a satisfactory account of the genesis of reason (Bildung), thus making rationality a kind of miracle (150-153). A more adequate picture of perception, which does not preclude the possibility of offering a genesis of reason, is offered by Husserl, as the author showed in the fourth chapter. Another problem concerns the transcendental significance of McDowell’s enterprise. Conceptualism, in McDowell’s view, is said to refer to “prior conditions of being directed at reality” (156). This way, any claim concerning the space of nature (actually, any claim at all) must be made through the space of reasons. But this clearly contradicts McDowell’s affirmations that “thinking and knowledge can after all be conceived of as natural phenomena” (156). In Van Mazijk’s view, there is no way to conceive the space of reasons as being both condition of and conditioned by the space of nature (156). Both Kant and Husserl show that this is a “transcendental absurdity”, since it “conflates distinct levels of explanations” (161).
On the way towards a conclusion, Van Mazijk points out that it is precisely this division of spaces which makes conceptualism attractive after all. That is, only if one accepts that the space of reasons consists exclusively of concepts, one will tend to ascribe conceptuality to perception (in order to make it rationally intelligible). But, as all the analyses of both Husserlian and Kantian framework have shown, there are good reasons not to consider concepts to be the exclusive accomplishment of rationality and therefore not to accept this division of spaces. The rest of the chapter is then dedicated to reinforcing the main conclusion of the book, namely the idea that the Kantian and (specially) Husserlian accounts of perception and reality avoid the inconsistencies generated by McDowellian conceptualism and offer, therefore, better alternatives to it. The final preference is given to the Husserlian framework, as it “provide[s] the most interesting and viable alternative when it comes to determining reference for concepts of the mental, as well as for specifying the contents of various types of sensible operations” (157).
In sum, Van Mazijk’s rich book does an excellent job of showing how the three authors work towards the same epistemological problems and have shared ambitions. To all of them, the Cartesian approach on subjectivity is misguided; and to all of them, it is precisely this approach that is at the basis of the epistemological problems concerning the gulf between mind and world. As to the overcoming of the Cartesian picture, they all want to reject transcendental realism, that is, the idea that reality is radically independent of our knowledge. This way, Kant, Husserl and McDowell intend to show that the world is a priori a world of rational experience. The conflict emerges when McDowell achieves that by appealing to the exclusively conceptual configuration of the world, which is denied by both Kant and Husserl. In this way, the book successfully accomplishes one of its purposes announced in the preface of “connecting [McDowell’s work] to key figures of the German transcendental tradition”, and so of “uncovering a continuing tradition hidden underneath today’s more specialized and fragmented philosophical landscape” (7). Therefore, it should appeal to anyone interested in a historical study of Kant, Husserl and McDowell. As to its more original purpose, “to develop new critical reflections on core tenets of McDowell’s philosophy” (7), that is principally achieved by the author’s recourse to Husserl in order to advocate weak conceptualism. I am not convinced, however, that the Husserlian perspective as offered here by the author is free of difficulties. At most, it seems to me to be as problematic as McDowell’s views. The early theory of fulfillment, as I have said, has many problems concerning the concepts of matter and fullness. As to the genetic analyses, the author himself recognizes that Husserl’s work on habit poses serious difficulties to the overall interpretation of his theory as conceptualist (weak or strong) or non-conceptualist. It seems that these problems should be faced more at length if Husserl is to be seriously considered as an alternative to conceptualism.
