1In 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.
2Husserl’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.
3Interestingly, 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.
4Thematically, 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.
5Zahavi’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.
6Zahavi 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.
7In 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.
8However, 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).
9Zahavi 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).
10So, 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.
11Zahavi’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.
12Zahavi 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.
13Zahavi 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.
14In 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).
15Zahavi 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.
16Zahavi’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.
17Contra 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).
18Instead, 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.
19To 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.
20As 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.
21The 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.
22In 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.
23The 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.
24According 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).
25Zahavi 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?
26Zahavi 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).
27These 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 ), 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 )” (Overgaard, 2018, 36).
28Zahavi 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.
29During 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.
30Either 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).
31The 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.
32Regarding 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.
33Zahavi 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.
34Zahavi 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.
35Zahavi’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.
36In 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.
37So, 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.
38I 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.References:
