1. Introduction

In the introduction of this review I will provide some general comments on the nature of the layout, methodology, and style of Zahavi’s work before moving into a detailed commentary. Page numbers refer to the reviewed work unless otherwise indicated.

Husserl’s Legacy is an attempt to defend Husserlian phenomenology from a variety of perceived misconceptions and misinterpretations that have been voiced from both within and outside of the Continental tradition. In particular, it is an attempt to show that Husserl avoids a variety of positions have been levelled at him as criticisms and which are, one assumes, perhaps seen as out of touch with contemporary trends in Anglophone philosophy, i.e. methodological solipsism, internalism, idealism, and metaphysical neutrality.

Interestingly, Zahavi does not attempt to show that one should reject any of these positions for their own reasons. Nor does he argue that one should reject these positions for the reasons Husserl did (and in fact Husserl’s arguments are not often provided). This remains implicit. The scope of the book is to show, via close study of Husserl’s corpus, that Husserl does indeed reject the aforementioned positions. As interesting as Husserl scholars will find this project, it is an unexpected turn from an author who has claimed that one “of phenomenology’s greatest weaknesses is it preoccupation with exegesis” (Zahavi, 2005, 6). The value of the project is that close exegesis serves to precisely locate Husserl’s position on contemporary philosophical issues. But I doubt that it will serve to bring anyone into the Husserlian tent that does not already have some affinity with it.

Thematically, the book has a cyclical character, and questions which are raised early on are returned to as the work unfolds; the central debates are interwoven throughout the work. The work is decisive, yet also full of Zahavi’s characteristic diplomacy, and his careful and considerate attention to detailed distinctions; Zahavi will often proceed by firstly teasing out different meanings of key concepts like metaphysics or naturalisation. In this work, Zahavi draws on his expert knowledge of the full range of Husserl’s collected works, drawing insightful quotes from a range of primary sources. Zahavi also shows his expertise concerning well known commentaries on Husserl from canonical figures like Heidegger and Merleau-Ponty, and a wealth of other Husserlian interpreters.

Zahavi’s methodological approach is to generally begin with a discussion of the position of an interlocutor who has claimed that Husserl held one of the aforementioned positions (i.e. solipsism, internalism, etc.). One method Zahavi then employs is to outline Husserl’s position on a given topic (say intersubjectivity), and on this basis to reason that it would be inconsistent to assume that Husserl held the position his interlocutors ascribe to him (i.e. methodological solipsism). Of course, this approach assumes that Husserl philosophy is internally consistent. Anyone familiar with the Fifth Meditation, for example, will know that Husserl struggled to bring about this consistency. An alternate method that Zahavi employs in dealing with an interlocutor is to provide a sample of excerpts drawn from a variety of Husserlian texts wherein Husserl explicitly disavows the position in question, or endorses an alternate position, i.e. when Husserl says that no “realist has been as realistic and concrete as me, the phenomenological idealist” (170). This second method is certainly enough to establish that Husserl believed that, on a certain rendering, he did not subscribe in a straightforward way to some of the positions he was reproached with (i.e. idealism), and it means we will need to approach our depiction of his position with care, as Zahavi does. However, like much of Husserl’s project, many of these quotes are what Hopkins describes as ‘promissory notes’—statements which require much filling in and detail if they are to be substantiated. Husserl did not always get around to paying these promissory notes out, and this raises a methodological hurdle for Zahavi.

Zahavi locates Husserl’s position on three central issues. 1) The relation between phenomenology and metaphysics, and the clash with speculative realism. 2) Internalism vs. externalism, and the question of methodological solipsism. 3) The naturalisation of phenomenology. There is far too much dense exegesis to provide an enlightening and comprehensive review in the space available here; I will discuss and provide some criticisms of Zahavi’s discussion of theme 1 and 2. As we shall see, Zahavi thinks that locating Husserl’s position on these themes pivots on the interpretation of two key aspects of the Husserlian framework: the noema and the reduction.

  1. Metaphysics and Phenomenology, Part 1.

In this section, I will trace Zahavi’s comments on the metaphysical relevance of Husserl’s early phenomenology. The relation between phenomenology and metaphysics is firstly raised in the second chapter of Husserl’s Legacy. The question which drives this investigative theme is whether or not Husserlian phenomenology can contribute to metaphysical discussions. Zahavi traces the source of Husserlian phenomenology’s purported metaphysical neutrality back to the earlier descriptive project of the Logical Investigations. As Zahavi outlines, for the author of the Investigations, the term metaphysics denoted a science which clarifies the presuppositions of the positive sciences. Metaphysics is, in this sense, the meta to physics. As Husserl is interested in the foundation of all sciences, pure and a priori ones included, he thus sees his project as superseding the metaphysical one. In this sense, Zahavi shows that Husserl saw phenomenology as meta-metaphysical, as various quotes from the Logical Investigations attest. We shall see later that Zahavi provisionally defines metaphysics as taking a position on the question of whether or not physical objects are real or purely mental (ideal) and, as Husserl’s early project does not deign to comment on this issue, it is on this basis that Zahavi views it as metaphysically neutral.

However, Zahavi shows that not everyone has seen Logical Investigations this way. Various interpreters have seen it as a realist manifesto. This reading is motivated by the strong rejection of representationalism which is contained in the Investigations—the reasoning being that, if Husserl is not an intra-mental representationalist, then he must be a metaphysical realist. In response Zahavi claims that this reading ignores one of the key distinction of the Investigations—that between intentional objects which happen to exist in the spatio-temporal nexus, and those that do not. This purely descriptive distinction refers only to modes of givenness, and is indicative of the manner in which the Investigations avoid metaphysics (36).

Zahavi similarly rejects an idealistic interpretation of the Investigations. For example, he discusses Philipse interpretation, which claims that Husserl identifies the adumbrations of an object with the immanent sensations via which these adumbrations are given to us and argues that, as all objects are given via adumbrations for Husserl, all objects are thereby reducible to our immanent sensations. Therefore, Husserl must be some sort of phenomenalist like Berkeley. Zahavi argues that Philipse ignores that Husserl distinguishes between differing parts of a perception, some of which are properties of the object itself, others of which are immanent sensations, and refers to both (unfortunately) as adumbrations. Husserl very clearly states that the reality of an object “cannot be understood as the reality of a perceived complex of sensations” (40).

So, Zahavi shows that, if we are talking about the descriptive project contained in the Investigations, then Husserlian phenomenology is indeed metaphysically neutral, in the sense that it does not take a realist or idealist position on the existential status of physical objects.

Zahavi’s discussion of Philipse utilises the method of providing direct citations from Husserl which contradict one of his interlocutor’s renditions. However, Zahavi also mentions here the spectre which, given this method, haunts Legacy: the validity of Husserl’s assessment of his own project (42). As Zahavi observes, Heidegger was certainly sceptical about Husserl’s evaluation of his own work. This problem is compounded by the fact that some of the claims about his own work are where Husserl spends some of his largest banknotes.

Zahavi agrees that Husserl does not always seem to view his own project clearly or consistently. To illustrate this, Zahavi considers the discrepancy between Husserl’s actual description of intentional acts and his second order reflections on what he is doing. On the one hand, Husserl seems to claim to restrict his analyses in Logical Investigations to the noetic and immanent psychic contents in certain parts. In parts of Ideas 1 Husserl again seems to endorse the claim that only the immanent sphere is totally evident and therefore fair game for phenomenology investigation. However, in both works, he clearly begins to analyse the noematic components of intentional experiences. Although this section is ostensibly in the thematic context of discussing Husserl’s reliability as a commentator on his own work, it very much pertains to the internalist/externalist debate which will take centre stage later, as it concerns the extent to which Husserl’s phenomenology engages with the external world. Indeed, these inconsistencies perhaps illuminate why some of Zahavi’s latter interlocutors have branded Husserl an internalist; perhaps these interlocutors are basing their evaluation on Husserl’s own comments.

Zahavi finishes the section on the Investigations by questioning whether one should react to the metaphysical neutrality contained therein as either liberating or constricting, but then adds the embracing and diplomatic remark that it might be both, or neither, depending on the metaphysical question under discussion. He adds that Husserl began to acknowledge that, if metaphysics is taken in the sense of more than an addendum to physical sciences, then perhaps it might be of relevance to the phenomenologist. He also thinks that there is no need to emphasise the value of the neutrality of the “Logical Investigations at the expense of Husserl’s later works” (47). So, on the one hand, Zahavi endorses the neutrality of the Logical Investigations and simultaneously proclaims its value, whilst on the other hand he paves the way for the more metaphysically relevant phenomenology which is to come with Husserl’s transcendental turn.

  1. Metaphysics and Phenomenology, Part 2.

In the opening of chapter 3, Zahavi draws on one commentator (Taylor Carman) who engages in a practice which is almost a rite of passage for any commentator on a post-Husserlian phenomenologist: showing how one of Husserl’s successors vastly improved on the project outlined by Husserl. These sorts of analyses almost always end up straw manning Husserl, and Zahavi is right to correct them. Zahavi recounts how Carman attributes the success of Heidegger’s project to his rejection of the method of phenomenological reduction (53). Zahavi shows that a similar account is provided by certain Merleau-Ponty commentators. Zahavi pinpoints that the inaccuracy of these accounts lies in their characterisation of the epoche and the reduction leading to solipsism and internalism (55).

Zahavi characterisation of the reduction emphasises Husserl’s comments which stress that the reduction does not involve a turning away from the world of everyday concerns, and that what is initially bracketed (i.e. the positing of the existential concrete person and the lifeworld they are in) is eventually reintroduced and accounted for. Indeed, for Husserl, it is only because phenomenology begins form the reduced ego that it can, eventually, give an accurate and expansive characterisation of the constitutive activities of consciousness and the existence of transcendental entities. The reduction is, on this reading, not an internalist shift. Zahavi will later also emphasise that, in fact, for Husserl just as the ego is the precondition for the constitution of the lifeworld, the transcendental ego is just as equally constituted by its factical engagement.

Zahavi’s discussion turns to the question of whether or not a transcendental Husserlian phenomenology, which is guided by the reduction, can contribute more to metaphysical discussions than the descriptive variety. Zahavi discusses that two prominent commentators, Crowell and Carr, both assert that the transcendental project is concerned with issues that have to do with meaning. On this rendition, because meaning is a concept which transcends being, transcendental phenomenology is thus unconcerned with reality—and metaphysics.

Contra Crowell and Carr, Zahavi argues that the latter Husserl does embrace metaphysical issues. He uses two strategies to make this claim. Firstly, Zahavi quotes a number of Husserlian passages which show that he thought that phenomenology began to embrace metaphysical questions, for example, when Husserl states that phenomenology “does not exclude metaphysics as such” (64 italics removed). However, as Zahavi then states, Husserl rejected some traditional meanings of the term metaphysics, and at other times was quite equivocal about what he meant by it, so some unpacking is required to determine exactly what Husserl’s really means when he says phenomenology might involve metaphysics. Zahavi explicitly avoids one of the ways that Husserl spelled out the claim that phenomenology did metaphysics (i.e. via the exploration of themes related to the ethical-religious domain and the immortality of the soul).

Instead, Zahavi sticks with the sense in which metaphysics is defined as pertaining “to the realism-idealism issue, i.e. to the issue of whether reality is mind-independent or not” (65). It is therefore surprising that an argument Zahavi makes is that Husserlian phenomenology is relevant to metaphysics in this sense because, if phenomenology had no metaphysical implications, then it could not reject both realism and idealism so unequivocally. The odd thing is that that Zahavi has just argued that, because Husserl rejected both of these positions in the Investigations, the early descriptive project is metaphysically neutral. Here he seems to argue that this rejection is a reason to accept that Husserl’s philosophy has metaphysical implications.

To unpack Zahavi’s claim a little more, however, he thinks that because Husserl took a stand on the relationship between phenomena and reality, phenomenology therefore has “metaphysical implications” (74). Zahavi argues that Husserl thought there can be no ‘real’ objects, in principle unknowable, behind appearances. For Husserl, the phenomena is the thing, but taken non-naively. It is thus Husserl’s characterisation of phenomena which imports the metaphysical implications Zahavi mentions. It thus doesn’t make any sense to talk about some other Ding-an-Sich behind the phenomena; it is nonsensical to say that the Kantian thing-in-itself exists.

As Zahavi notes, for Husserl “the topics of existence and non-existence, of being and non-being, are… themes addressed under the broadly understood titles of reason and unreason” (66). So, questions concerning the existence of the thing-in-itself can be referred to our account of the rational experience of objects in the world. According to this account, for Husserl ‘existence’ entails the possibility of an experience which provides evidence for a thing. The possibility of this experience, however, must be a real and motivated one, and belong to the horizon of an actually existing consciousness. It must not be a purely empty and formal possibility. Put another way, the world and nature cannot be said to exist unless there is an actual ego which also exists that can, in principle at least, experience this world in a rationally coherent way. Thus, “reason, being, and truth are inextricably linked” (72). And so, as a result, we can deny the possibility of a mind independent and in principle unknowable reality, and we can also deny any form of global scepticism. Ontological realism and epistemological idealism are both false. I was left a little uncertain how this position is any less neutral than the one advocated for in the Logical Investigations.

The section on metaphysics can be subject to the criticism that Zahavi proceeds to cite Husserl’s text on a particular issue, and rarely provides any further argumentation or clarification. For example, Zahavi notes that Husserl states that it “is impossible to elude the extensive evidence that true being as well only has its meaning as the correlate of a particular intentionality of reason” (72). One is left wondering what evidence Husserl could possibly be referring to, and therefore why we ought to accept this enigmatic claim. Elsewhere, Zahavi states that “the decisive issue is not whether Husserl was justified in rejecting global scepticism, but simply that he did reject the very possibility of reality being fundamentally unknowable” (73). This is perhaps the decisive issue within the (narrow exegetical) context of Zahavi’s discussions. But surely Zahavi recognises that a lot hinges on Husserl’s justification for his position, especially within the context of the project of keeping Husserl’s philosophy relevant.

In fact, towards the end of the work, Zahavi shows that he is aware of this objection. He states that his “aim in the foregoing text has been to elucidate and clarify Husserl’s position, rather than to defend it or provide independent arguments for it” (208). And it is really the final chapter, when Zahavi places Husserl’s phenomenology in confrontation with speculative realism, that his detailed exegesis of metaphysics bears serious polemical fruit. But even then, what one could take away from these later sections is that certain interpretations of Husserl are incorrect, and that perhaps Husserl’s position is more coherent or valuable than that of the speculative realists. Zahavi is aware of the need for more detailed and concrete analyses than the ones he has provided, and even notes that Husserl “remained unsatisfied ‘as long as the large banknotes and bills are not turned into small change’ (Hua Dok 3-V/56). A comprehensive appraisal of his philosophical impact would certainly have to engage in a detailed study of the lifeworld, intentionality, time-consciousness, affectivity, embodiment, empathy, etc.” (211). Such small change can only be rendered by a close examination of the things themselves, however.

  1. Internalism vs. Externalism, Part 1.

The fourth chapter aims to situate transcendental Husserlian phenomenology within the context of the internalism vs. externalism debate. Zahavi notes that several commentators (namely, Rowlands, Dreyfus, Carman, and McIntyre) have considered Husserl an “archetypal internalist” (79), often using Husserl’s position as a foil to later phenomenologist like Sartre or Heidegger. Zahavi traces this conception of Husserl to the West coast ‘Fregean’ interpretation of the noema. Zahavi strategy, as he states (82), is not to argue for the East coast interpretation (he considers this issue settled, has addressed it in earlier books (Zahavi, 2003), and provides references for the works he considers decisive on this issue). He shows, instead, that if the East coast interpretation is correct, then Husserl is not so much of an archetypal internalist after all.

According to Zahavi and the East coast interpretation, the noema is not an extraordinary (i.e. abstract) object. It is not a concept, or a sense, or a propositional content. It is an ordinary object, but considered in an extraordinary (phenomenological) attitude. There is not an ontological difference between the object and the noema, but a structural difference only recognised post reduction. Thus, the reduction does not shift our focus from worldly objects to intra-mental representational (i.e. semantic) content of some sort, via which an act is directed to the aforementioned worldly objects. No, the reduction reveals that consciousness is correlated with worldly objects which themselves bear the content that is presented in intentional acts (83-84).

Zahavi then discusses that the West coast critique of the East coast interpretation would align Husserl with modern day disjunctivism, because of the trouble in accounting for non-veridical experiences like hallucinations. In short, if perception is just of ordinary objects as the East coast interpretation maintains, and there is no internal representational mediator (as disjunctivists agree), then what accounts for the difference between veridical and non-veridical experiences which seem indistinguishable?

Zahavi observes that Husserl distinguishes between two experiences which contain objects that seem the same, but are not. Thus, if I look at an object, and then the object is replaced unbeknownst to me as I close my eyes, then even though upon opening my eyes I think my perception is of the same object, Husserl makes a distinction between the two perceptions, because the object they intend are not identical. Thus, an experience in which an existing object and a seemingly existing (but hallucinatory) object are given are not identical either, even if they seem so. This response is paired with the more experientially based point that hallucinations and perceptions do not, in fact, ever seem the same. A perceptual experience is one which is given within a horizon that unfolds over time, and is intersubjectively verifiable. Hallucinations do not meet these experiential criterions (87-88).

These passages contain convincing arguments for Husserl’s position that could be brought to bear on the contemporary debate between conjunctivists and disjunctivists, but ignore recent work by Overgaard. Overgaard claims that “Husserl believes illusions and hallucinations can be indistinguishable from genuine, veridical perceptions. Husserl grants ‘the possibility of an exactly correspondent illusion’ (Hua XIX/1, 458 [137]), and maintains that ‘differences of […] veridical and delusive perception, do not affect the internal, purely descriptive (or phenomenological) character of perception’ (Hua XIX/1, 358 [83])” (Overgaard, 2018, 36).

Zahavi spends some time recounting various passages which are favoured by the East and West coast schools respectively. He lends his support to Fink’s interpretation, according to which the noema can be considered in both a transcendental and psychological context, and he claims that the fault of the West coast school is taking it solely in the latter. Importantly, he says that grasping the transcendental rendition of the noema is predicated on a proper understanding of the transcendental aspects of the reduction. The transcendental function of the reduction is to collapse the distinction between the reality and being of worldly objects and their “constituted validity and significance” (92). It is the West coast, overly psychological reading of the reduction as an internalist form of methodological solipsism which leads them to an internalist rendering of the noema as an intra psychic representational entity.

During the discussion of the noema, the inconsistency and lack of clarity concerning Husserl’s own work on this topic lurks in the background. The simple fact is, Husserl’s doctrine of the noema is sometimes unclear, on either the West or East coast interpretation, and leaves many questions unanswered. Zahavi acknowledges this when he discusses Bernet’s article that outlines “no fewer than three different concepts of the noema” (93). At this point, Zahavi toys with the conciliatory idea that perhaps there is support for both the East and West Coast reading. What Zahavi decides is that we should seek Husserl’s mature view, and one which coheres with the rest of his ideas. However, perhaps this affords Husserl too much charity; I suspect an outsider to Husserlian phenomenology would conclude as much. Perhaps the correct conclusion is that Husserl’s doctrine of the noema is confused.

Either way, Zahavi concludes that, if internalism is defined as the theory that our access to the world is mediated and conditioned by internal representations, then we can conclude Husserl is not an internalist (94), assuming one follows Zahavi’s interpretive approach to the reduction and the noema. If the reduction is seen clearly, and the distinction between objects in the world and noemata is partially collapsed, it cannot be maintained that the subject who intends a noema is cocooned in their own internal representational prison which is disjointed from the world. For Husserl, objects/meanings are actually in the world, and correlated with consciousness, which is a centre for disclosure (94).

  1. Internalism vs. Externalism, Part 2.

The next objection Zahavi addresses is that the foregoing discussion cannot be reconciled with the fact that Husserl’s is a self-confessed transcendental idealist, and ergo an internalist. Thus, like much of the book, we return to the theme of attempting to unravel exactly what Husserl’s transcendental idealism amounts to. In this section, Zahavi explores two crucial aspects to this problem: 1) understanding the constitutive relationship. 2) Understanding key passages from Ideas 1. My review will end with a discussion of these points.

Regarding the first point, Zahavi’s thinks that we should divorce the notion of constitutive dependence from substance metaphysics. The orld does not depend on one type of substance or another for its constitution. For Husserl, the world does not supervene or reduce to some other type of substance, but depends on being known. In this sense, transcendental “idealism is not participating in… the debate between monists and dualists. Its adversary is not materialism, but objectivism” (102). In the end of this discussion, Zahavi seems also suggests that there is an bidirectional constitutive correlation between consciousness and world (102), something he again suggests in latter passages concerning the factical embeddedness of consciousness (section 4.4). In this sense, Husserl’s thesis of constitution is less internalist than might be assumed, as the world constitutes consciousness as much as vice versa.

Zahavi then turns his attention to discussing the passages in sections 47-55 of Ideas 1 which contain some of Husserl’s most strident commitments to idealism. He mentions the notorious section 49, wherein Husserl claims that consciousness subsists after the annihilation of the world. How are we to square this with Husserl’s purported externalism? Zahavi argues that the best way to interpret this passage is that it expresses Husserl’s commitment to two theses: firstly, that some form of consciousness is non-intentional and, secondly, it is the intentional form of consciousness which is “world involving”, i.e. inextricably correlated with the world. Thus, if the world were annihilated, then intentional consciousness would cease, but if consciousness per se is divorced from intentional consciousness, then some form of consciousness could survive this cessation. So, Husserl can maintain that some form of consciousness is ‘externalised’, whilst another form of consciousness is independent from world experience.

Zahavi then turns to Husserl’s claim (found in section 54) that the being of consciousness is absolute, whilst the being of the world is only ever relative. How can we reconcile this with an externalism that avoids affirming consciousness at the expense of the reality of the world? Zahavi’s controversially rejects the traditional interpretation of this passage, according to which in making this claim Husserl means that consciousness is given absolutely and not via adumbrations, unlike spatial objects which are always adumbrated. Zahavi claims that this reading “falls short” (105), but (surprisingly) never mentions how.

Zahavi’s alternate reading is that Husserl most often talks about the absolute in the context of inner time consciousness. Zahavi claims that the absoluteness of temporal consciousness is intimately linked with the prereflectiveness of consciousness, and that we ought to interpret Husserl’s comments concerning the absolute being of consciousness to mean that consciousness is always prereflectively given. Zahavi is right that sometimes Husserl speaks of the absolute in this context. But this is not really the context in which the passage in question in Ideas 1 occurs.

In section 42 and 44 of Ideas 1, Husserl explicitly connects modes of givenness (i.e. adumbrated vs. non-adumbrated) with modes of being (i.e. contingent vs. absolute). For example, he says that every perception of a mental process is “a simple seeing of something that is (or can become) perceptually given as something absolute” (Husserl, 1983, 95). Note the phraseology: given as absolute. In section 54, Husserl states that transcendental consciousness survives even after psychic life has been dissolved and annulled. The central contrast which Husserl makes in this passage is that even intentional psychological life, and the life of the Ego, is relative when compared to pure or absolute nature of transcendental consciousness. Zahavi is right that Husserl may here may be thinking of the prereflective givenness of the absolute temporal flow. But Husserl does not name what remains after consciousness has been divorced from psychological egological life. He nowhere here mentions concepts like the temporal stream and prereflective consciousness.

So, another parsimonious interpretation is that Husserl talks about the absolute in two contexts, one relating to the connection between modes of givenness and modes of being, and one relating to the different strata of temporal consciousness and prereflective givenness. Now, one might argue that Husserl ultimately sees one context as foundational for the other. In fact, Zahavi has shown elsewhere that Husserl certainly thinks that the capacity to reflect presupposes prereflective consciousness, and in Ideas 1 Husserl says that the “‘absolute’ which we have brought about by the reduction… [i.e. pure consciousness] has its source in what is ultimately and truly absolute”, i.e. temporal flow (Husserl, 1983, 192) . However, Husserl then notes the current discussion has thus far “remained silent” concerning this ultimate absolute, and that we can, for now, “leave out of account the enigma of consciousness of time” (Ibid, 194), barring a cursory account of the threefold structure of temporality. And so, it’s difficult to see how we should read the passages in section 54 as concerning the absoluteness of temporality, as Husserl explicit directs us away from this theme in Ideas 1. And, I don’t think we can direct discussions about reflective givenness to a discussion of temporality (and on to prereflectiveness) without further ado, as Zahavi seems to do here.

I just don’t think the selected passage from Ideas 1 is the best way to get to a discussion of temporal consciousness and prereflective givenness in relation to the concept of the absolute. Zahavi chooses to take this direction because he is concerned that the traditional reading of these passages puts Husserl in the position of a metaphysical or absolute idealist (105). My final point is that this need not be the case as, even on the traditional reading, Husserl’s talk of the ‘absolute’ in Ideas 1 is not leading to an ontological claim. Because, the thesis that consciousness is given absolutely in reflective acts could just as well be labelled a descriptive one, as it rests on a distinction between modes of access to states of consciousness.

This is a book long overdue. Other authors have made more or less recent phenomenological and transcendental-idealist contributions to the philosophy of mathematics: Dieter Lohmar (1989), Richard Tieszen (2005) and Mark van Atten (2007) are perhaps the most important ones. Ten years is a sufficiently wide gap to welcome any new work. Yet da Silva’s contribution stands out for one reason: it is unique in the emphasis it puts, not so much, or not only, on the traditional problems of the philosophy of mathematics (ontological status of mathematical objects, mathematical knowledge, and so on), but on the problem of the application of mathematics. The author’s chief aim – all the other issues dealt with in the book are subordinated to it – is to give a transcendental phenomenological and idealist solution to the evergreen problem of how it is that we can apply mathematics to the world and actually get things right – particularly mathematics developed in complete isolation from mundane, scientific or technological efforts.

Chapter 1 is an introduction. In Chapters 2 and 3, da Silva sets up his tools. Chapters 4 to 6 are about particular aspects of mathematics: numbers, sets and space. The bulk of the overall case is then developed in Chapters 7 and 8. Chapter 9, “Final Conclusions”, is in fact a critique of positions common in the analytic philosophy of mathematics.

Chapter 2, “Phenomenology”, is where da Silva prepares the notions he will then deploy throughout the book. Concepts like intentionality, intuition, empty intending, transcendental (as opposed to psychological) ego, and so on, are presented. They are all familiar from the phenomenological literature, but da Silva does a good job explaining their motivation and highlighting their interconnections. The occasional (or perhaps not so occasional) polemic access may be excused. The reader expecting arguments for views or distinctions, however, will be disappointed: da Silva borrows liberally from Husserl, carefully distinguishing his own positions from the orthodoxy but stating, rather than defending, them. This creates the impression that, at least to an extent, he is preaching to the converted. As a result, if you are looking for reasons to endorse idealism, or to steer clear of it, this may not be the book for you.

Be that as it may, the main result of the chapter is, unsurprisingly, transcendental idealism. This is the claim that, barring the metaphysical presuppositions unwelcome to the phenomenologist, there is nothing more to the reality of objects than their being “objective”, i.e., public. ‘Objectivation’, as da Silva puts it, ‘is an intentional experience performed by a community of egos operating cooperatively as intentional subjects. … Presentifying to oneself the number 2 as an objective entity is presentifying it and simultaneously conceiving it as a possible object of intentional experience to alter egos (the whole community of intentional egos)’ (26-27). This is true of ideal objects, as in the author’s example, but also of physical objects (the primary type of intentional experience will then be perception).

There are two other important views stated and espoused in the chapter. One is the Husserlian idea that a necessary condition for objective existence is the lack of cancellation, due to intentional conflict, of the relevant object. Given the subject matter of the book, the most important corollary of this idea is that ideal objects, if they are to be objective, at the very least must not give rise to inconsistencies. For example, the set of all ordinals does not objectively exist, because it gives rise to the Burali-Forti paradox. The other view, paramount to the overall case of the book (I will return to it later), is that for a language to be material (or materially determined) is for its non-logical constants to denote materially determined entities (59). If a language is not material, it is formal.

Chapter 3 is about logic. Da Silva attempts a transcendental clarification of what he views as the trademark principles of classical logic: identity, contradiction and bivalence. The most relevant to the book is the third, and the problem with it is: how can we hold bivalence – for every sentence p, either p or not-pand a phenomenological-idealist outlook on reality? For bivalence seems to require a world that is, as da Silva puts it, ‘objectively complete’: such that any well-formed sentence is in principle verifiable against it. Yet how can the idealist’s world be objectively complete? Surely if a sentence is about a state of affairs we currently have no epistemic access to (e.g., the continuous being immediately after the discrete) there just is no fact of the matter as to whether the sentence is true or false: for there is nothing beyond what we, as transcendental intersubjectivity, have epistemic access to.

Da Silva’s first move is to put the following condition on the meaningfulness of sentences: a sentence is meaningful if and only if it represents a possible fact (75). The question, then, becomes whether possible facts can always be checked against the sentences representing them, at least in principle. The answer, for da Silva, turns on the idea, familiar from Husserl, that intentional performances constitute not merely objects, but objects with meanings. This is also true of more structured objectivities, such as states of affairs and complexes thereof – a point da Silva makes in Chapter 2. The world (reality) is such a complex: it is ‘a maximally consistent domain of facts’ (81). The world, then, is intentionally posited (by transcendental intersubjectivity) with a meaning. To hold bivalence as a logical principle means, transcendentally, to include ‘objective completeness’ in the intentional meaning (posited by the community of transcendental egos) of the world. In other words, to believe that sentences have a truth value independent of our epistemic access to the state of affairs they represent is to believe that every possible state of affairs is in principle verifiable, in intuition or in non-intuitive forms of intentionality. This, of course, does not justify the logical principle: it merely gives it a transcendental sense. Yet this is exactly what da Silva is interested in, and all he thinks we can do. Once we refuse to assume the objective completeness of the world in a metaphysical sense, what we do is to assume it as a ‘transcendental presupposition’ or ‘hypothesis’. In the author’s words:

How can we be sure that any proposition can be confronted with the facts without endorsing metaphysical presuppositions about reality and our power to access reality in intuitive experiences? … By a transcendental hypothesis. By respecting the rules of syntactic and semantic meaning, the ego determines completely a priori the scope of the domain of possible situations – precisely those expressed by meaningful propositions – which are, then, hypothesized to be ideally verifiable. (83)

Logical principles express transcendental hypotheses; transcendental hypotheses spell out intentional meaning. … The a priori justification of logical principles depends on which experiences are meant to be possible in principle, which depends on how the domain of experience is intentionally meant to be. (73)

There is, I believe, a worry regarding da Silva’s definition of meaningfulness in terms of possible situations: it seems to be in tension with the apparent inability of modality to capture fine-grained (or hyper-) intensional distinction and therefore, ultimately, meaning (for a non-comprehensive overview of the field of intensional semantics, see Fox and Lappin 2005).[1] True, since possible situations are invoked to define the meaningfulness, not the meaning, of sentences, there is no overt incompatibility; yet it would be odd to define meaningfulness in terms of possible situations, and meaning in a completely different way.

Chapter 4, “Numbers”, has two strands. The first deals with another evergreen of philosophy: the ontological status of numbers and mathematical objects in general. Da Silva’s treatment is interesting and his results, as far as I can see, entirely Husserlian: numbers and other mathematical objects behave like platonist entities except that they do not exist independently of the intentional performances that constitute them. One consequence is that mathematical objects have a transcendental history which can and should be unearthed to fully understand their nature. The phenomenological approach is unique in its attention to this interplay between history and intentional constitution, and it is to da Silva’s credit, I believe, that it should figure so prominently in the book. Ian Hacking was right when he wrote, a few years back, that ‘probably phenomenology has offered more than analytic philosophy’ to understand ‘how mathematics became possible for a species like ours in a world like this one’ (Hacking 2014). Da Silva’s work fits the pattern.

And yet I have a few reservations, at least about the treatment (I will leave the results to readers). For one thing, there is no mention of unorthodox items such as choice sequences. Given da Silva’s rejection of intuitionism in Chapter 3, perhaps this is unsurprising. Yet not endorsing is one thing, not even mentioning is quite another. I cannot help but think the author missed an opportunity to contribute to one of the most engaging debates in the phenomenology of mathematics of the last decade (van Atten’s Brouwer Meets Husserl is from 2007). Da Silva’s seemingly difficult relationship with intuitionism is also connected with another conspicuous absence from the book. At p. 118 da Silva looks into the relations between our intuition of the continuum and its mathematical construction in terms of ‘tightly packed punctual moments’, and argues that the former does not support the latter (which should then be motivated on different grounds). He cites Weyl as the main purveyor of an alternative model – which he might well be. But complete silence about intuitionist analysis seems frankly excessive.

A final problem with da Silva’s presentation is his dismissal of logicism as a philosophy of, and a foundational approach to, mathematics. ‘Of course,’ he writes, ‘Frege’s project of providing arithmetic with logical foundations collapsed completely in face of logical contradiction (Russell’s paradox)’ (103). The point is not merely historical: ‘Frege’s reduction of numbers to classes of equinumerous concepts is an unnecessary artifice devised exclusively to satisfy logicist parti-pris … That this caused the doom of his projects indicates the error of the choice’. I would have expected at least some mention of either Russell’s own brand of logicism (designed, with type theory, to overcome the paradox), or more recent revivals, such as Bob Hale’s and Crispin Wright’s Neo-Fregeanism (starting with Wright 1983) or George Bealer’s less Fregean work in Quality and Concept (1982). None of these has suffered the car crash Frege’s original programme did, and all of them are still, at least in principle, on the market. True, da Silva attacks logicism on other grounds, too, and may argue that, in those respects, the new brands are just as vulnerable as the old. Yet, that is not what he does; he just does not say anything.

The second strand of the chapter, more relevant to the overall case of the book, develops the idea that numbers may be regarded in two ways: materially and formally. The two lines of investigation are not totally unrelated, and indeed some of da Silva’s arguments for the latter claim are historical. The claim itself is as follow. According to da Silva, numbers are essentially related to quantity: ‘A number is the ideal form that each member of a class of equinumerous quantitative forms indifferently instantiates’, and ‘two numbers are the same if they are instantiable as equinumerical quantitative forms’ (104).[2] Yet some types of numbers are more or less detached from quantity: if in the case of the negative integers, for example, the link with quantity is thin, when it comes to the complex numbers it is gone altogether. Complex numbers are numbers only in the sense that they behave operationally like ones – but they are not the real (no pun intended) thing. Da Silva is completely right in saying that it was this problem that moved the focus of Husserl’s reflections in the 1890s from arithmetic to general problems of semiotic, logic and knowledge. The way he cashes out the distinction is in terms of a material and a formal way to consider numbers. Genuine, ‘quantitative’ numbers are material numbers. Numbers in a wider sense, and thus including the negative and the complex, are numbers in a formal sense. Since, typically, the mathematician is interested in numbers either to calculate or because they want to study their relations (with one another or with something else), they will view numbers formally – i.e., at bottom, from the point of view of operations and structure – rather than materially.

Thus, the main theoretical result of the chapter is that, inasmuch as mathematics is concerned with numbers, it is ‘essentially a formal science’ (120). In Chapter 7, da Silva will put forward an argument to the effect that mathematics as a whole is essentially a formal science. This, together with the idea, also anticipated in Chapter 4, that the formal nature of mathematics ‘explains its methodological flexibility and wide applicability’, is the core insight of the whole book. But more about it later.

Chapter 5 is about sets. In particular, da Silva wants to transcendentally justify the ZFC axioms. This includes a (somewhat hurried) genealogy, roughly in the style of Experience and Judgement, of ‘mathematical sets’ from empirical collections and ‘empirical sets’. The intentional operations involved are collecting and several levels of formalisation. The details of the account have no discernible bearing on the overarching argument, so I will leave them to one side. It all hinges, however, on the idea that sets are constituted by the transcendental subject through the collecting operation, and this is what does the main work in the justification. This makes da Silva’s view very close to the iterative conception (as presented for example in Boolos 1971); yet he only mentions it once and in passing (146). Be that as it may, it is an interesting feature of da Silva’s story that it turns controversial axioms such as Choice into sugar, while tame ones such as Empty Set and Extensionality become contentious.

Empty Set, for example, is justified with an account, which da Silva attributes to Husserl, of the constitution of empty sets that I found fascinating but incomplete. Empty sets are clearly a hard case for the phenomenological account: because, as one might say, since collections are empty by definition, no collecting is in fact involved. Or is it? Consider, da Silva says, the collection of the proper divisors of 17:

Any attempt at actually collecting [them] ends up in collecting nothing, the collecting-intention is frustrated. Now, … Husserl sees the frustration in collecting the divisors of 17 as the intuitive presentation of the empty collection of the divisors of 17. So empty collections exist. (148)

It is a further question, and da Silva does not consider it, whether this story accounts for the uniqueness of the empty set (assuming he thinks the empty set is indeed unique, which, as will appear, is not obvious to me). Are collecting-frustration experiences all equal? Or is there a frustration experience for the divisors of 17, one for the divisors of 23, one for the round squares, and so on? If they are all equal, does that warrant the conclusion that the empty sets they constitute are in fact identical? If they are different, what warrants that conclusion? Of course, an option would be: it follows from Extensionality. Yet, I venture, that solution would let the phenomenologist down somewhat. More seriously, da Silva even seems to reject Extensionality (and thus perhaps the notion that there is just one empty set). At least: he claims that there is ‘no a priori reason for preferring’ an extensional to an intensional approach to set theory, but that if we take ‘the ego and its set-constituting experiences’ seriously we ought to be intensionalists (150).

Chapters 6 is about space and its mathematical representations – ‘a paradigmatic case of the relation between mathematics and empirical reality’ (181). It is where da Silva deals the most with perception and the way it relates with mathematical objects. For the idealist, there are at least four sorts of space: perceptual, physical, mathematical-physical and purely formal. The intentional action required to constitute them is increasingly complex, objectivising, idealising and formalising. Perceptual space is subjective, i.e., private as opposed to public. It is also ‘continuous, non-homogeneous, simply connected, tridimensional, unbounded and approximately Euclidean’ (163). Physical space is the result of the intersubjective constitution of a shared spatial framework by harmonization of subjective spatial experiences. This constitution is a ‘non-verbal, mostly tacit compromise among cooperating egos implicit in common practices’ (167). Unlike its perceptual counterpart, physical space has no centre. It also admits of metric, rather than merely proto-metric, relations. It is also ‘everywhere locally’, but not globally, Euclidean (168). The reason is that physical space is public, measurable but based merely on experience (and more or less crude methods of measurement) – not on models.

We start to see models of physical space when we get to mathematical-physical space. In the spirit of Husserl’s Krisis, da Silva is very keen on pointing out that mathematical-physical space, although it does indeed represent physical space, does not reveal what physical space really is. That it should do so, is a naturalistic misunderstanding. In the author’s words:

At best, physical space is proto-mathematical and can only become properly mathematical by idealization, i.e., an intentional process of exactification. However, and this is an important remark, idealization is not a way of uncovering the “true” mathematical skeleton of physical space, which is not at its inner core mathematical. (169)

Mathematical-physical space is what is left of the space we live in – the space of the Lebenswelt, if you will – in a representation designed to make it exact (for theoretical or practical purposes). Importantly, physical space ‘sub-determines’ mathematical-physical space: the latter is richer than the former, and to some extent falsifies what it seeks to represent. Euclidean geometry is paradigmatic:

The Euclidean representation of physical space, despite its intuitive foundations, is an ideal construct. It falsifies to non-negligible extent perceptual features of physical space and often attributes to it features that are not perceptually discernible. (178)

The next step is purely formal representations of space. These begin by representing physical space, but soon focus on its formal features alone. We are then able to do analytic geometry, for example, and claim that, ‘mathematically, nothing is lost’ (180). This connects with da Silva’s view that mathematics is a formal science and, in a way, provides both evidence for and a privileged example of it. If you are prepared to agree that doing geometry synthetically or analytically is, at bottom, the same thing, then you are committed to explain why that is so. And da Silva’s story is, I believe, a plausible candidate.

Chapter 7 is where it all happens. First, and crucially, da Silva defends the view that mathematics is formal rather than material in character. I should mention straight away that his argument, a three-liner, is somewhat underdeveloped. Yet it is very clear. To say that mathematics is essentially formal is, for da Silva, to say that mathematics can only capture the formal aspects of reality (as the treatment of space is meant to show). The reason is as follows. Theories are made up of symbols, which can be logical or non-logical. The non-logical symbols may, in principle, be variously interpreted. A theory whose non-logical symbols are interpreted is, recall, material rather than formal. Therefore, one could argue, number theory should count as material. Yet, so da Silva’s reasoning goes, ‘fixing the reference of the terms of an interpreted theory is not a task for the theory itself’ (186). The theory, in other words, cannot capture the interpretation of its non-logical constant: that is a meta-theoretical operation. But then mathematical theories cannot capture the nature, the specificity of its objects even when these are material.

That is the master argument, as well as the crux of the whole book. For it follows from it that mathematics is essentially about structure: objects in general and relations in which they stand. This, for da Silva, does not mean that mathematics is simply not about material objects. That would be implausible. Rather, the claim is that even when a mathematical theory is interpreted, or has a privileged interpretation, and is therefore about a specific (‘materially filled’) structure, it does not itself capture the interpretation (the fixing of it) – and thus it is really formal. Some mathematical theories are, however, formal in a stricter sense: they are concerned with structures that are kept uninterpreted. These are purely formal structures. Regarding space, Hilbert’s geometry is a good example.

Da Silva’s solution to the problem of the applicability of mathematics is thus the following. Mathematics is an intentional construction capable of representing the formal aspects of other intentional constructions – mathematics itself and reality. Moreover, it is capable of representing only the formal aspects of mathematics and reality. It should then be no surprise, much less a problem, that any non-mathematical domain can be represented mathematically: every domain, insofar as it is an intentional construction, has formal aspects – which are the only ones that count from an operational and structural standpoint.

This has implications for the philosophy of mathematics. On the ground of his main result, da Silva defends a phenomenological-idealist sort of structuralism, according to which structures are the privileged objects of mathematics. Yet his structuralism is neither in re nor ante rem. Not in re, because structures, even when formal, are objects in their own right. Not ante rem, because structures are intentional constructs, and thus not ontologically independent. They depend on intentionality, but also on the material structures on whose basis they are constituted through formalisation. This middle-ground stance is typical of phenomenology and transcendental idealism.

I have already said what the last two chapters – 8 and 9 – are about. The latter is a collection of exchanges with views in the analytic philosophy of mathematics. They do not contribute to the general case of the book, so I leave them to prospective readers. The former is an extension of the results of Chapter 7 to science in general. A couple of remarks will be enough here. Indeed, when the reader gets to the chapter, all bets are off: by then, da Silva has put in place everything he needs, and the feeling is that Chapter 8, while required, is after all mere execution. This is not to understate da Silva’s work. It is a consequence of his claim (217) that the problem of the applicability of mathematics to objective reality, resulting in science, just is, at bottom, the problem of the applicability of mathematics to itself – which the author has already treated in Chapter 7. Under transcendental idealism, objective, physical reality, just like mathematical reality, is an intersubjective intentional construct. This construct, being structured, and thus having formal aspects to it, ‘is already proto-mathematical’ and, ‘by being mathematically represented, becomes fully mathematical’ (226). The story is essentially the same.

Yet it is only fair to mention that, while in this connection it would have been easy merely to repeat Husserl (the approach is after all pure Krisis), that is not what da Silva does. He rather distances himself from Husserl in at least two respects. First of all, he rejects what we may call the primacy of intuition in Husserl’s epistemology of mathematics and science. Second, he devotes quite a bit of space to the heuristic role of mathematics in science – made possible, so the author argues, by the formal nature of mathematical representation (234).

As a final remark, I want to stress again what seems to me the chief problem of the book. Da Silva’s aim is to give a transcendental-idealist solution to the problem of the applicability of mathematics. Throughout the chapters, he does a good job spelling out the details of the project. Yet there is no extensive discussion of why one should endorse transcendental idealism in the first place. True, a claim the author repeatedly makes is that idealism is the only approach that does not turn the problem into a quagmire. While the reader may be sympathetic with that view (as I am), da Silva offers no full-blown argument for it. As a result, the book is unlikely to build bridges between phenomenologists and philosophers of mathematics of a more analytic stripe. Perhaps that was never one of da Silva’s aims. Still, I believe, it is something of a shame.
