KANT’S GOAL IN THE TRANSCENDENTAL DEDUCTION was to demonstrate that the categories are applicable to objects of sensible intuition. He carried out this task by disclosing the necessity of a transcendental synthesis. In the Transcendental Deduction in the second edition of the Critique of Pure Reason transcendental synthesis has two subspecies: synthesis intellectualis and synthesis speciosa. The distinction between the two types of transcendental synthesis is also mirrored in the structure of the proof of the (...) B Deduction. As several commentators have noted, the B Deduction in fact contains two parts. Each part seems to provide an account of a distinctive kind of transcendental synthesis. The first part provides an account of intellectual synthesis while the second part provides an account of figurative synthesis. (shrink)

Talk at University of Turin, 'Kant, oltre Kant, May 5th 2023. --- -/- It is useful, while keeping in mind a holistic approach, to concentrate on a common theme in Kant’s text, which it will turn out is the quintessential element of his novel ‘way of thinking’, as he himself put it in preface of the second edition of the Critique of Pure Reason. This common theme is the idea of synthesis, which is what holds together, and is the (...) entryway to, all the other familiar aspects of Kant’s thought: his concept of self-consciousness or how mind is involved in cognition, his ideas about the role of the imagination, his theory of knowledge and his metaphysics of experience, and not unimportantly, its relation to what is probably the most Kantian element here: the categories of the understanding as the first principles of knowledge. But the meaning of synthesis and its role in its various facets, though frequently the subject of discussion in papers and monographs alike, is hardly understood in contemporary Kant scholarship. Most readings of the text of the Deduction, the part in which Kant elucidates his concept of synthesis, exhibit a shallow, mechanical understanding of it. -/- A compounding factor is that synthesis can’t really be understood independently of the other aforementioned elements of Kant’s thought. Grasping the meaning of synthesis implies coming to grips with his concept of self-consciousness and the way both self-consciousness and the categories are intricately and intimately involved. Most interpretations consider these aspects too much as if they were indeed separable faculties or entities that serve separable functions, undercutting an important feature of Kant’s metaphysics: the possibility of a priori unified cognition, for which an indivisible self-legislating subject is responsible. Rather, they are expressions of various aspects of a singular function of the mind as the ground of possible unified knowledge. -/- One striking example of such a superficial reading of the text is the way the relation between figurative synthesis and intellectual synthesis—or in the case of the A-Deduction the threefold synthesis—is standardly interpreted, as if the two are independent or quasi-independent functions of different faculties of the mind, the imagination and the understanding. In this paper, I focus on the relation between figurative and intellectual synthesis, while arguing that failing to understand this properly, indeed the relation between the imagination and the understanding, leads to a vicious regress in the explanation of the ground of knowledge, for which a priori synthesis is specifically designed. In other words, failing to see the intimate relation between the imagination and the understanding, the very identity that lies at their root, risks losing sight of the primary aim of Kant’s thought: the possibility of a priori unified knowledge.

This is a system of pure speculative reason in answer to the challenge issued by Immanuel Kant, in his "Critique of Pure Reason," with regard to metaphysics; the challenge being clearly mentioned in the Appendix to his "Prolegomena..." wherein he asks his Reviewer to take any one of his four sets of contradictory propositions, and offer an a priori judgment/proposition of his own that would overturn the antinomy, and thus, allow room for the possibility of raising metaphysics to the (...) level of a science, meaning a synthesis of judgments, from pure reason, self-evidently a priori, therefore, necessary; and that as a synthesis of pure understanding, would relate to and help us make sense of reality, that is, the world of our experience.

A neo-Kantian debate within analytic philosophy, in our reading, would evaluate thevalue of the following question: how the codification of the elements of a representation creates spaces of identification to theorize the possibilities oftruth, in two fields, the analytical and in the synthetic? In the analytic, the theory involves theability to conceptually interpret relations of possibility and impossibility; in the synthetic, thetheory involves the extra-conceptual supplementation of the alignment with the verifiers,providing a measure to encode the semantic contribution of both (...) experience simpliciter andexperience with concepts, made by schemas, analogical systems, etc. We suggest revitalizingthe theory of a priori syntheses, dialoguing with Kantian aspects of Husserl’s SixthInvestigation and confronting the orthodox semantics of empiricist inspiration.Although, in large part, a theory of judgments is equivalent to a dynamic production of models,simplifications and analogies, the focus on the production of synthetic and a priori judgmentspresents some independent problems, which, in our reading, would enrich the universe ofanalytic philosophy and would facilitate the reading of the development of the pragmatic shiftphase, which took place in the second half of the 20th century.Keywords: synthesis a priori; semantics; pragmatism.

The paper is devoted to the role (function) of reflection in cognition and its modes (types) as part of the cognitive ability. Along with logical and transcendental reflection, Kant's transcendental shift (turn) is discussed, as well as the role of reflection in Kant's schematism (the ability to judge) and the formation of schemas. Particular attention is paid to another mode of reflection – reflexive switching, which underlies not only the formation of pure rational concepts and schemes (Kant's concept of epigenesis; (...) metaphysical deduction of categories), but the epigenesis of a priori forms of sensibility of space and (especially) time, connected with the Kantian synthesis of apprehension in the intuition. The article proposes an original conception of time, the so-called onion model of time, which is based on a reflexive (iterative) apperceptive ladder. (shrink)

In this chapter I advance a moderately conceptualist interpretation of Kant’s account of the threefold synthesis in the A-Deduction. Often the first version of TD, the A-Deduction, is thought to be less conceptualist than the later B-version from 1787 (e.g. Heidegger 1991, 1995). Certainly, it seems that in the B-Deduction Kant puts more emphasis on the role of the understanding in determining the manifold of representations in intuition than he does in the A-Deduction. It also appears that in the (...) A-Deduction the seemingly pre-conceptual aspects of a priori synthesis, namely those of the synthesis of apprehension and the imagination, are more prominently featured than in the B-Deduction. And the fact that in the A-Deduction judgement does not appear to play any significant role reinforces the view that the A-Deduction is less strongly conceptualist. I believe that Kant is a conceptualist also in the A-Deduction (as much as in the B-Deduction) in the sense that all syntheses, which are expounded in the second section of the A-Deduction, must be seen as involving the categories or the understanding as the seat of the categories. However, despite some apparent strong modal claims regarding apperception in the A-Deduction, I argue that Kant is a moderate conceptualist in the sense that he allows for the real possibility that some representations are apprehended that are not subsumed or subsumable under the categories, or determined or determinable by the understanding as the seat of the categories. Not all representations must be synthesised and hence be conceptualised (by means of the categories), nor are all representations necessarily conceptualisable (by means of the categories). Often it is argued that the application of the categories must be seen as separate from or prior to conceptualisation (that is, employment of concepts in a judgement), so that the categories must be considered to apply to representations at least to the extent that the productive imagination or recognitive synthesis is involved, even if no empirical concepts are applied in an actual judgement. But it is difficult to see how categories can apply outside the context of an actual judgement in which ipso facto empirical concepts are employed, because, after all, categories are nothing but logical functions of judgement (e.g. B143). More in particular, I shall argue for the claims that (1) appearances to the contrary, all three levels of syntheses in the A-Deduction, including the synthesis of recognition, are interdependent and are not to be seen as operating singly or independently of each other, and hence of the categories; (2) ‘mere’ apprehension, or ‘mere’ intuition, is not dependent on the understanding and the application or possible application of the categories; and that (3) ‘mere’ apprehension does not even invoke a priori synthesis of apprehension and hence is as such fully lawless in terms of Kantian a priori laws. In this context, I also address Kant’s argument in the A-Deduction about the role of the imagination in the production of spatial objects and explain his apt use of the example of cinnabar to show that the kind of association that is at issue here concerns the possibility of knowledge, not the possibility of mere association, as is often assumed.

Um dos aspectos característicos da fundamentação epistemológica da etologia de Konrad Lorenz é a tentativa de síntese entre a teoria darwiniana e a gnosiologia kantiana. A partir dessa premissa, delinearemos, antes de tudo, uma breve história da tradição transcendentalista, focalizando a atenção em alguns elementos que seus críticos consideraram insustentáveis. Em segundo lugar, analisaremos a tentativa de Lorenz de implantar a estrutura transcendental em suas pesquisas etológicas, com uma consequente naturalização do conceito de "a priori". Em terceiro lugar, veremos (...) como a atribuição de a priori próprios das espécies particulares abre a possibilidade de interpretar a epistemologia de Lorenz de duas maneiras distintas, aparentemente conflitantes. Finalmente, preferiremos uma dessas interpretações e mostraremos como ela permite o entendimento das distintas modalidades de conhecimento animal e humano. One of the main features of Konrad Lorenz's epistemological foundation of ethology is the attempt of synthesis between Darwinian theory and Kantian gnosiology. Starting from this premise I will outline, first of all, a brief history of transcendentalist tradition, focusing attention on some elements that its critics have regarded as untenable. Secondly, I will analyze Lorenz's attempt to implant the transcendental structure in his ethological researches as being a consequence of the naturalization of the concept of "a priori". Thirdly, I will see how the attribution of a priori proper to single species opens the possibility of interpreting the epistemology of Lorenz in two apparently conflicting ways. Finally, I will prefer one of these interpretations and I will show that it enables us to understand the distinct modalities of animal and human knowledge. (shrink)

Kant’s philosophy of mathematics presents two fundamental problems of interpretation: (1) Kant claims that mathematical truths or “judgments” are synthetic a priori; and (2) Kant maintains that intuition is required for generating and/or understanding mathematical statements. Both of these problems arise for us because of developments in mathematics since Kant. In particular, the axiomatization of geometry--Kant’s paradigm of mathematical thinking--has made it seem to some commentators as, for example, Russell, that both (1) and (2) are false (Russell 1919, p. (...) 145).2 If virtually all of mathematics, including geometry, is axiomatizable, it would seem that mathematics results in analytic judgments that are totally independent of sensibility, the source, according to Kant, of intuition. In this paper I will address both of these difficulties. I shall argue that Kant’s understanding of both “synthetic” and “intuition” make his position immune to these criticisms. (shrink)

Kant’s theory of cognition aimed to explain the possibility of scientific knowledge. Aesthetics and life science were not considered by Kant in the context of cognition. By contrast, Cassirer set himself a philosophical task to extend Kant’s theory of cognition to all forms of culture, including pre-scientific knowledge and aesthetics. The present study demonstrates how Cassirer explained the possibility of different objective forms, named symbolic, by employing and transforming Kant’s theory of cognition. For this goal, Cassirer took the following steps: (...) modified the definitions of a priori synthesis (the act of understanding) and pure intuition (the forms of space and time) - main building blocks of Kant’s cognition; indicated the necessary correlation of intuition and synthesis; characterized a priori synthesis and the intuition as notions which include contradicted meanings. Cassirer called this contradiction “twofold oppositions” as characteristic of a priori synthesis. The first argument of the article is that the possibility of various synthetic acts is rooted in the nature of a priori synthesis which carries together two different meanings: the act of uniting elements and the initial unity. One synthetic act forms the world of nature and is connected to scientific space and time, and the other is the product of immediate perceptional space and time, from which the world of myth and aesthetics appears. Thus, Cassirer expanded the scope of “pure” synthesis. The second argument is that Cassirer specified a priori synthesis and pure intuition as a functional concept. The functional concept belongs to the model of concept as-relation that Cassirer has elaborated. It includes moments that are separated and united simultaneously. This definition of concept breaks the rules of consistency. The concept of as-relation justifies the contradictory characteristics of a priori synthesis and pure intuition, which include both the combination of moments in a synthesizing act and the initial unity of intuition.

This is a technical treatise for the scientific-minded readers trying to expand their intellectual horizon beyond the straitjacket of materialism. It is dedicated to those scientists and philosophers who feel there is something more, but struggle with connecting the dots into a more coherent picture supported by a way of seeing that allows us to overcome the present paradigm and yet maintains a scientific and conceptual rigor, without falling into oversimplifications. Most of the topics discussed are unknown even to neuroscientists, (...) biologists, philosophers, and yet are based on the findings published in their own mainstream peer reviewed literature or on deep insights of the scientific, philosophical and spiritual giants of the past. -/- A scientific, philosophical, and spiritual overview of the relationship between science and spirituality, neuroscience and the mystery of consciousness, mind and the nature of reality, evolution and life. A plaidoyer for a science that goes beyond the curve of reason and embraces a new synthesis of knowledge. The overcoming of the limitations of the intellect into an extended vision of ourselves and Nature. A critique of physicalism, the still-dominant doctrine that believes that all reality can be reduced to matter and the laws of physics alone. A review and reassessment of the old and new philosophical and metaphysical ideas which attempts to bring closer Western and Eastern traditions where science, philosophy, consciousness, Spirit and Nature are united in a grand vision that transcends the limited conventional scientific and philosophical paradigm. A possible answer to the questions of purpose and meaning and the future evolution of humankind beyond a conception that posits a priori a purposeless and meaningless universe. A report of the new scientific discoveries of a basal intelligence in cells and plants, on the question if mind is computational, the issue of free will, the mind-body problem, and the so called ‘hard problem of consciousness’. An essay on ancient as modern philosophical conceptions, from the One of Plotinus, the God of Spinoza until the recent revival of panpsychism or the universal consciousness. A journey into quantum physics from the perspective of philosophical idealism and an invitation to adopt new ways of seeing that might help us to transform our present understanding, expanding it into an integral cosmology, with a special emphasis on the spiritual and evolutionary cosmology of the Indian seer Sri Aurobindo. -/- Not just a philosophical and metaphysical meditation but, rather, an appeal to work towards a change of consciousness, a widening of our perspective towards a new way of seeing beyond a purely mechanistic worldview to avoid a social, environmental and economic collapse. Humans are transitional beings that will have to make a choice: relapse into a pre-rational state or evolve towards a new trans-rational species supported by an ideal of human unity in diversity as the expression of a spiritual evolutionary process, the call of the Spirit on Nature.

In this paper, I argue that Sellars’s conceptualist reading of Kant, though less radical than more contemporary approaches (e. g., Brandom, McDowell), relies on a controversial account of the relations between the givenness of intuitions, the productive imagination and the power of judgment. I will discuss: 1) how Sellars reconsidered Kant’s account of intuition; and 2) the kind of conceptualism he argues for. I will raise two main claims. First, Sellars’s conceptualist reading of intuition overlooks the role of space and (...) time as givenness conditions. Second, Sellars’s account of the productive imagination disregards the complementary significance of the power of judgment in a priori synthesis, the role of which is to grant synthetic unity. My aim is to reconstruct a consistent dialogue between Sellars and Kant by discussing Sellars’s reading of a priori synthesis and comparing his views to Kant’s original aims. (shrink)

My aim in this paper is to go some way towards showing that the maintenance of hard and fast dichotomies, like those between mind and body, and the real and the virtual, is untenable, and that technological advance cannot occur with being cognisant of its reciprocal ethical implications. In their place I will present a softer enactivist ontology through which I examine the nature of our engagement with technology in general and with virtual realities in particular. This softer ontology is (...) one to which I will commit Kant, and from which, I will show, certain critical moral and emotional consequences arise. It is my contention that Kant’s logical subject is necessarily embedded in the world and that Kant, himself, would be content with this view as an expression of his inspired response to the ‘‘scandal to philosophy... that the existence of things outside us... must be accepted merely on faith’’ [Bxl]. In keeping with his arguments for the a priori framing of intuition, the a priori structuring of experience through the spontaneous application of the categories, the synthesis of the experiential manifold, and the necessity of a unity of apperception, I will present an enactivist account of agency in the world, and argue that it is our embodied and embedded kinaesthetic engagement in our world which makes possible the syntheses of apprehension, reproduction and recognition, and which, in turn, make possible the activity of the reproductive or creative imagination.

Fifteen years after the first edition of this comprehensive work, German historicism remains largely and conspicuously in the shadows. The great historico-philological and historico-sociological work produced by, and on the fringes of, this school has given way to specialization. Great polygraphs of the caliber of a Meinecke, a Vossler, a Curtius, a Cassirer, a Croce, or an Auerbach seem to have completely disappeared from the scene. But is the necessity for cultural synthesis that these men stressed any less urgent (...) today than before? One of the major tasks envisioned by thinkers of the early twentieth century was the development of a philosophical anthropology which would consolidate all the preceding work of cultural synthesis. Today this task remains in the far horizon after a series of distinguished but discontinuous achievements. Thus the reappearance of the ambitious work of Professor Rossi is a welcome event. There are now indications that sociology is moving away from the neutral functionalism of the consensus years and is beginning to show some interest in the subconscious and in concrete constellations of values representative of communal forms of consciousness in a situation. Post-industrial society can no longer be examined with the rough tools of micro- or even macro-analysis. Because of their refinements in quantification and their awareness of the most specific features of every particular form of group consciousness, the new middle range methods are akin to the synthetic spirit of the historical school. As middle range research progresses, its results can provide the ontic ground for an ontology of the human condition in its adjustment to the world, and in its communicative-transcendent goals. For this reason, Rossi’s work, though excellent in its expository aspects should be read with care to avoid overemphasizing, as he does, the distance between rationalism and irrationalism that was apparent in the main tendencies of the historical school. Surely it is a worthwhile thing to show the tensions between the relativists such as Simmel and Spengler, the intuitionists such as Windelband and Rickert, and finally the neo-idealists such as Troeltsch and Meinecke. The tension that pulled apart these intellectual currents shows by contrast the great synthetic force operative in the systems of Dilthey and Weber, which provided the dominant inspiration for the whole school. But the fundamental perspective in today’s reconsideration of historicism need not be the tempering of any search for ideals through the insistence on sober methodological limits. A more fruitful emphasis can be placed today on action as a mediator between thought and adjustment, on community as a mediator between society and individuals, and most of all on expression and adventure as mediators between survival and moral absolutes. With his neo-Kantian insistence on the historical method, on the discovery of the historical horizon of the human condition, and on the establishment of the institutional connections within historical periods, Professor Rossi: a) misses the point of the anti-mechanistic efforts of modern philosophy, i.e., the constitution of synthetic a priori judgments in their true home grounds, the field of spontaneous human communication and action; b) restricts the ability on the part of the historical method to penetrate and elucidate the areas of the unconscious and of passive syntheses ; c) both presupposes and trivializes the definition of freedom. Freedom in Rossi’s interpretation of historicism, seems to result from the objective displacement of values, rather than from the dramatic insufficiency of every finite person as it transpires in the highest forms of symbolic communication and interaction.—A.

In this chapter, I show that there is at least one crucial, non-short, argument, which does not involve arguments about spatiotemporality, why Kant’s subjectivism about the possibility of knowledge, argued in the Transcendental Deduction, must lead to idealism. This has to do with the fact that given the implications of the discursivity thesis, namely, that the domain of possible determination of objects is characterised by limitation, judgements of experience can never reach the completely determined individual, i.e. the thing in itself (...) or the unlimited real, but only objects as objects of possible experience. As such, it can be shown by reference to a key argument from Kant, that Hegel’s famous criticism that Kant is not licensed, on the basis of his core arguments concerning the original-synthetic unity of apperception, to restrict our knowledge to appearances, is mistaken on purely systematic grounds. More specifically, I argue that idealism follows already from the constraints that the use of the categories, in particular the categories of quality, places on the very conceivability of things in themselves. My claim is that, although it is not only possible but also necessary to think things in themselves, it does not follow that by merely thinking them we have a full grasp of the nature of things in themselves, as some important commentators claim we have. We must therefore distinguish between two kinds of conceiving of things in themselves: conceiving in the standard sense of ‘forming the notion of’, and conceiving in the narrow sense of ‘having a determinate intellectual grasp’. So although we must be able notionally to think things in themselves, as the grounds of their appearances, we cannot even conceive, through pure concepts, of how they are in themselves in any determinate, even if merely intellectual, sense. To put it differently, we cannot have a positive conception of things in themselves (this is in line with Kant’s distinction between noumena in the negative and positive senses; cf. B307–9). For support, I resort to a much overlooked chapter in the Critique, concerning the transcendental Ideal, where Kant discusses what it is for a thing to be a thing in itself proper, namely, something that is thoroughly determined. This concerns the real ontological conditions of things, which are not satisfied by the modal categories alone, namely, their existence conditions. I claim that the chief reason why, given Kant’s view of determinative judgement, we cannot determine a thing in itself is because of two connected reasons: (1) a thing in itself is already fully determined and therefore not further determinable and (2) we cannot possibly determine all of the thing’s possible determinations. In this context, I also discuss the notion of material (not: empirical) synthesis—of which Kant speaks in the chapter on the transcendental Ideal—which must be presupposed as the ground of the formal a priori synthesis that grounds possible experience. This material synthesis, which is an idea of reason that defines a thing as thoroughly determined with regard to all of its possible predicates and has mere regulative status, can by implication not be determined by the forms of the understanding, which synthesise only a limited set of predicates. As a result, given this definition of ‘thing in itself’, any object (appearance) as at best44 a limited set of determinations of the thing can never be numerically identical to the thing in itself as thoroughly determined individual. This undercuts a standard assumption about the identity relation between appearances and things in themselves in many contemporary interpretations of Kant’s transcendental idealism. (shrink)

In the Transcendental Aesthetic of the Critique of Pure Reason, Immanuel Kant famously claims that we have an a priori intuition of space as an ‘infinite given magnitude’. Later on, in the Transcendental Analytic, he seems to add that the intuition of space presupposes a synthetic activity of the transcendental imagination. Several authors have recently pointed out that these two claims taken together give rise to two problems. First, it is unclear how the transcendental imagination of a finite mind (...) could ever result in the intuition of an entity that is infinitely large. Second, Kant claims that our intuition of space has a ‘whole-prior-to-its-parts’ structure, such that its parts are given only as limitations of the whole, while synthesis is compositional and has a ‘parts-prior-to-their-whole’ structure, because it consists in first running through and then taking together the parts of a sensible manifold. I will solve these two problems by showing that Kant thought that synthesis does not always have a compositional structure but that there is also a form of ‘decomposing’ synthesis, which has a whole-prior-to-its-parts structure. Building on similarities between Kant, Edmund Husserl and G. W. F. Hegel, I will argue that infinite space is given to us in intuition by precisely such an activity of decomposition, one that allows us to differentiate between finite spatial objects and the unlimited phenomenal horizon in which they appear.

Deleuze's theory of time set out in Difference and Repetition is a complex structure of three different syntheses of time – the passive synthesis of the living present, the passive synthesis of the pure past and the static synthesis of the future. This article focuses on Deleuze's third synthesis of time, which seems to be the most obscure part of his tripartite theory, as Deleuze mixes different theoretical concepts drawn from philosophy, Greek drama theory and mathematics. (...) Of central importance is the notion of the cut, which is constitutive of the third synthesis of time defined as an a priori ordered temporal series separated unequally into a before and an after. This article argues that Deleuze develops his ordinal definition of time with recourse to Kant's definition of time as pure and empty form, Hölderlin's notion of ‘caesura’ drawn from his ‘Remarks on Oedipus’ (1803) and Dedekind's method of cuts as developed in his pioneering essay ‘Continuity and Irrational Numbers’ (1872). Deleuze then ties together the conceptions of the Kantian empty form of time and the Nietzschean eternal return, both of which are essentially related to a fractured I or dissolved self. This article aims to assemble the different heterogeneous elements that Deleuze picks up on and to show how the third synthesis of time emerges from this differential multiplicity. (shrink)

Kant calls the Principle of the Synthetic Unity of Apperception the “highest point” to which we “must affix all use of the understanding, even the whole of logic and, after it, transcendental philosophy.” In this article, I offer an original interpretation of this “supreme principle.” My argument is twofold. First, I argue that the common identification of this principle with the “I think” or even the form of the I think misses the basis on which this principle is capable of (...) grounding Kant’s transcendental deduction. It must be understood as a purely formal, transcendental principle. Second, I argue that this highest principle must be understood as a purely formal principle of pure synthesis in order for Kant’s account of the mind to lay valid claim to such spontaneity without invoking the very dogmatic idealism that he critiques. The reduction of this principle to the real I think, or even to the Transcendental Unity of Apperception, undermines the basic distinction on which Kant’s deduction depends. I pay particular attention to important, recent arguments from Longuenesse on the TUA, Williams on the Original Unity of Apperception, Allison and Pollok on the status of a priori principles, and McLear on the claim that unity necessarily presupposes synthesis.

How synthetic a priori judgments possible problem is that Kant's "Critique of Pure Reason," the basic problem. Possibility of a priori truth is the problem, and integrated synthetic a priori judgments is to answer the key question of truth.

In this paper, the analysis related to (...) the concept of a joint examination, but also pointed out that the concept of comprehensive and clues throughout the cornerstone of criticism lies. How the sythetic judgements a priori are possible is the basic problem of kant's critic of pure reason. The question of the possibility is also the question of transendental truth, and to answer it, the concept of synthesis is the pivot. The fourfold meaning of the concept of synthesis is investigated in this article, which is the sythesis of the logic, the epistemology, the methodology, and the ontology. The related concept of analysis is also investigated jointly, but it is emphasized that the concept of synthesis is the footstone and clue of the whole critic. (shrink)

The article shows that three antirealistic theories of classical analysis and synthesis are logically possible: presentationistic, solipsistic and Kantian, but only the latter is actually being developed. Revealed its specific features and features shared with other, logically possible antirealistic theories. The correlation of the Kantian theory of analysis and synthesis of knowledge with his theory of analysis and synthesis of subjects of knowledge is analyzed. Gnoseological problems that forced Kant to assert that new knowledge is provided only (...) by the synthesis of knowledge, and analysis only clarifies the results of synthesis, are characterized. The Kantian solution to these problems is correlated with their realistic solution. The role that the Kantian "Copernican revolution in philosophy" plays in his interpretation of the analysis and synthesis of subjects of knowledge is investigated. The Kantian theory of analytical and synthetic judgments is considered. It is shown that the Kantian question "how are synthetic judgments a priori possible?" is essentially a question about the nature of theoretical knowledge, which was historically formed in ancient geometry precisely as the unity of analysis and synthesis. A qualitative difference is shown between classical and geometric (by origin) analysis and synthesis. Three historical stages of their formation are described. The assertion of I. Newton that the natural science experiment arose as a result of the extension of the method of geometric analysis and synthesis to the natural sciences is investigated. (shrink)

The words "analysis" and "synthesis" are among the most widely used and misused terms in the history of philosophy. They were originally used in geometrical reasoning during the age of Euclid to describe two opposing, but complementary, methods of arguing (roughly equivalent to deduction and induction). Since then philosophers have used them not only in this way, but also to refer to distinctions of various sorts between types of judgment or classes of propositions. To some they are regarded as (...) defining differences of kind, while others regard them as defining differences of degree. Moreover, they have been connected in numerous different ways with other distinctions, such as "a priori vs. a posteriori" or "necessary vs. contingent". Some philosophers have become so frustrated at the ambiguity attached to the various uses of the terms "analytic" and "synthetic" that they have given up all hope of assigning a coherent meaning to this distinction.

Taken together with other plausible theses, Millianism has the counterintuitive consequence that the following belief reports have the same semantic content. (1a) Lois Lane believes that Superman flies. (1b) Lois Lane believes that Clark Kent flies. It has been popular, at least since the publication of Salmon's Frege's Puzzle (1986), to explain the presence of anti-Millian intuitions in terms of pragmatic phenomena. According to Salmon's account, (1a) and (1b) can be used to communicate distinct propositions, and this leads to the (...) mistaken conclusion that (1a) and (1b) differ in semantic content. Since the publication of Soames's Beyond Rigidity (2002) and Thau's Consciousness and Cognition (2002), it has been popular to say that (1a) and (1b) can be used to communicate descriptive propositions. These propositions may be distinct, and this contributes to the mistaken conclusion that (1a) and (1b) differ in semantic content. In this paper, I elaborate and defend a modified version of Salmon's account. This new account incorporates elements from Soames and Thau, so it can be regarded as a synthesis of previous accounts. It is argued that the new account is superior in various respects, not the least of which is its ability to handle various puzzles and problematic cases. Because of the elements that are incorporated from Soames and Thau, the new account can be regarded as an example of Millian Descriptivism. After explaining and motivating Salmon's account, I consider several problems. I then propose the modified account as an attractive way of avoiding these problems. It is noted that there are several similarities between the modified account and the accounts offered by Soames and Thau, but it is argued that the new account is superior in maintaining certain elements of Salmon's original account. Several consequences of the new account are discussed. Some of them concern the nature of the a priori and others concern the individuation of beliefs. I conclude by defending the new account against recent attacks on Millian Descriptivism. I argue that the new account is not suspectible to the objections that have been standardly raised against Fregean Descriptivism. (shrink)

Abstract. In Dynamics of Reason Michael Friedman proposes a kind of synthesis between the neokantianism of Ernst Cassirer, the logical empiricism of Rudolf Carnap, and the historicism of Thomas Kuhn. Cassirer and Carnap are to take care of the Kantian legacy of modern philosophy of science, encapsulated in the concept of a relativized a priori and the globally rational or continuous evolution of scientific knowledge,while Kuhn´s role is to ensure that the historicist character of scientific knowledge is taken (...) seriously. More precisely, Carnapian linguistic frameworks, guarantee that the evolution of science procedes in a rational manner locally,while Cassirer’s concept of an internally defined conceptual convergence of empirical theories provides the means to maintain the global continuity of scientific reason. In this paper it is argued that Friedman’s neokantian account of scientific reason based on the concept of the relativized a priori underestimates the pragmatic aspects of the dynamics of scientific reason. To overcome this short-coming, I propose to reconsider C.I. Lewis’s account of a pragmatic the priori, recently modernized and elaborated by Hasok Chang.

Is contemporary continental philosophy making a break with Kant? The structures of knowledge, taken for granted since Kants Critique of Pure Reason, are now being called into question: the finitude of the subject, the phenomenal given, a priori synthesis. Relinquish the transcendental: such is the imperative of postcritical thinking in the 21st century. Questions that we no longer thought it possible to ask now reemerge with renewed vigor: can Kant really maintain the difference between a priori and (...) innate? Can he deduce, rather than impose, the categories, or justify the necessity of nature? Recent research into brain development aggravates these suspicions, which measure transcendental idealism against the thesis of a biological origin for cognitive processes. In her important new book Catherine Malabou lays out Kants response to his posterity. True to its subject, the book evolves as an epigenesis – the differentiated growth of the embryo – for, as those who know how to read critical philosophy affirm, this is the very life of the transcendental and contains the promise of its transformation.

This book develops a textually grounded reconstruction of Kant’s argument in the Metaphysical Deduction. The argument proceeds in three steps, developing, first, a concept of judgment on which to base the table of logical functions, next a concept of synthesis of intuition that explains the content of the categories, and finally a concept of the understanding on which the categories belong a priori to the same faculty through which we judge. -/- The investigation presented here is an argumentative (...) reconstruction of Kant’s text. The text in question is the "Guiding Thread to the Discovery of all Pure Concepts of the Understanding" in both the 1781 (A) and 1787 (B) editions of the Critique of Pure Reason (A64-83/B89-113). To illuminate Kant’s reflections in this chapter, the reconstruction also draws on passages from elsewhere in the Critique, from Kant’s writings after the Critique, as well as notes from his Nachlass and student transcriptions of lectures he held during and subsequent to writing the Critique. Four passages, in particular, are of central importance: (i) the retrospective description of the task of the Metaphysical Deduction at B159, (ii) the retrospective description of the procedure of the "Guiding Thread" at A299/B355f., (iii) the section "On the A Priori Grounds for the Possibility of Experience" in the A-edition Transcendental Deduction of the Categories (A95-110), and (iv) §§15-21 in the B-edition Transcendental Deduction (B128-148). -/- The present interpretation of the Metaphysical Deduction thus emerges from a detailed and comprehensive analysis of the "Guiding Thread" that draws on related passages from the indicated portion of Kant’s corpus and, especially, on the aforementioned four passages from the Critique. Viewing these texts together and in a specific relation to one another suggests a reading which leaves little room for doubt. This sort of textually sensitive but charitable reconstruction helps to bring out the enduring force and interest of Kant’s philosophical position. [For Dennis Schulting's review for "Kantian Review" see under "External Links" below.] -/- -- -/- Wie hier durch textnahe und argumentative Rekonstruktion erstmals gezeigt wird, entwickelt Kant in der Metaphysischen Deduktion in drei Schritten: (i) einen Begriff des Urteils, auf dem die Tafel logischer Funktionen beruht; (ii) einen Begriff der Synthesis der Anschauung, der die Inhalte der Kategorien erklärt; und (iii) einen Begriff des Verstandes, demzufolge die Kategorien a priori zu demselben Vermögen gehören, durch das wir auch urteilen. -/- Die vorliegende Untersuchung ist eine argumentative Rekonstruktion von Kants Text. Der rekonstruierte Text ist der „Leitfaden der Entdeckung aller reinen Verstandesbegriffe" auf A 64 bis 83 / B 89 bis 113 der Kritik der reinen Vernunft in ihren beiden Auflagen von 1781 (A) und 1787 (B). Zudem werden andere, für ein Verständnis der Überlegungen in diesem Kapitel erforderliche oder zumindest erhellende Textstellen aus der Kritik herangezogen; aus Schriften, die Kant nach der Kritik geschrieben hat; sowie schließlich aus Kants Nachlass-Notizen und aus Nachschriften zu seinen Vorlesungen jeweils seit der Entstehungszeit der Kritik. Von entscheidender Bedeutung sind dabei vor allem vier weitere Passagen der Kritik selbst: i) die rückblickende Beschreibung der Aufgabe der Metaphysischen Deduktion auf B 159, ii) die rückblickende Beschreibung des Vorgehens im „Leitfaden" auf A 299/B 355 f., iii) der Abschnitt „Von den Gründen a priori zur Möglichkeit der Erfahrung" auf A 95 bis 110 der Transzendentalen Deduktion der Kategorien in der ersten Auflage und schließlich iv) die §§ 15 bis 21 auf B 128 bis 148 der Transzendentalen Deduktion der Kategorien in der zweiten Auflage der Kritik. -/- Vor dem Hintergrund einer umfassenden und detaillierten Analyse des „Leitfadens", bei Hinzuziehung verwandter Stellen aus dem umgrenzten Textbestand und nicht zuletzt bei Berücksichtigung des Verhältnisses des „Leitfadens" zu den genannten vier Passagen der Kritik legt sich eine Interpretation der Metaphysischen Deduktion nahe, die sich nur schwer bestreiten lässt, sobald diese Texte einmal gemeinsam betrachtet und auf eine bestimmte Weise zueinander ins Verhältnis gesetzt werden. Dabei kann eine durchgehend wohlwollende, argumentative Rekonstruktion dazu beitragen, auch die philosophische Überzeugungskraft der Position Kants deutlich zu machen.

ABSTRACT This essay will explore the constitution of a transcendental theory of space through an examination of the notion of spatial synthesis in the works of Husserl, Paliard, and Deleuze. First, we shall explore the constitution of the sensorial fields in Husserl’s phenomenology. In Husserlian terms, space is not originally an empty form that can eventually be filled with a certain empirical content. Accordingly, the philosopher claims that spatiality is a consequence of the immanent synthesis of sensations. Then, (...) we will move on to Jacques Paliard’s psychology of perception, where we will find both aesthetic and noetic synthesis as transcendental conditions for the perception of space. Lastly, we will explore Deleuze’s theory of intensive space, specifically the concept of depth developed in a dialogue with Paliard. This comparative analysis shows that purely intensive fields of individuation are a transcendental a priori for the perception of an extensive space. (shrink)

In recent years many influential philosophers have advocated that philosophy is an a priori science. Yet very few epistemology textbooks discuss a priori knowledge at any length, focusing instead on empirical knowledge and empirical justification. As a priori knowledge has moved centre stage, the literature remains either too technical or too out of date to make up a reasonable component of an undergraduate course. Edwin Mares book aims to rectify this. This book seeks to make accessible to (...) students the standard topics and current debates within a priori knowledge, including necessity and certainty, rationalism, empiricism and analyticity, Quine's attack on the a priori, Kantianism, Aristotelianism, mathematical knowledge, moral knowledge, logical knowledge and philosophical knowledge.

Abstract: My aim is to reconstruct Kant's argument for the principle of the synthetic unity of apperception. I reconstruct Kant's argument in stages, first showing why thinking should be conceived as an activity of synthesis (as opposed to attention), and then showing why the unity or coherence of a subject's representations should depend upon an a priori synthesis. The guiding thread of my account is Kant's conception of enlightenment: as I suggest, the philosophy of mind advanced in (...) the Deduction belongs to an enlightenment epistemology. Kant's conception of enlightenment turns on the requirement that a subject be able to recognize herself as the source of her cognitions. The argument for the apperception principle is reconstructed under the guidance of this conception of the ideal of enlightenment. (shrink)

The contention in this paper is that central to Sellars’s famous attempt to fuse the “manifest image” and the “scientific image” of the human being in the world was an attempt to marry a particularly strong form of scientific naturalism with various modified Kantian a priori principles about the unity of the self and the structure of human knowledge. The modified Kantian aspects of Sellars’s view have been emphasized by current “left wing” Sellarsians, while the scientific naturalist aspects have (...) been championed by “right wing” Sellarsians, the latter including William Rottschaefer’s constructive criticisms of my own reconciling interpretation of Sellars. In this paper I focus first on how (1) Sellars’s Kantian conception of the necessary a priori unity of the thinking self does not conflict with his ideal scientific naturalist conception of persons as “bundles” or pluralities of scientifically postulated processes. This then prepares the way for a more comprehensive discussion of how (2) Sellars’s modified Kantian account of the substantive a priori principles that make possible any conceptualized knowledge of a world does not conflict with his simultaneous demand for an ideal scientific explanation and evolutionary account of those same conceptual capacities. Sellars’s own attempted via media synthesis—what I call his “Kantian scientific naturalism”—merits another look from both the left and the right. (shrink)

Der Autor bietet eine Darstellung spannungsreicher Formen der transzendentalen Einheit, die Kants Auffassung der Synthesis erhellt. Die Abhandlung beginnt mit Reflexionen zur Synthesis, die den historischen und systematischen Rahmen der Untersuchung bestimmen, und erläutert dann Unterscheidungen und Übergänge zwischen Kritik, Transzendentalphilosophie und Metaphysik als Teilen des Systems der reinen Philosophie. Damit wird die verkannte Funktion dieser Systematik in der Aufstellung des apriorischen Leitfadens für den Erkenntnisgebrauch der Vernunft umrissen. Ein Leitfadenproblem, mit dem sich die,,metaphysische Deduktion" der Kategorien beschäftigt, (...) liegt aber zuallererst im Kern der Kritik. Das zweite Kapitel legt diesen verschlüsselten Textabschnitt aus, insbesondere seinen grundlegenden, oft von der Frage nach der Vollständigkeit der Kategorientafel überschatteten Anspruch, die Begriffe a priori der Einheit aller Verstandesfunktionen ‑ der Synthesis der Anschauung und des Urteils ‑ systematisch darzustellen. Die Überlegung zur Verstandesfunktion gibt schließlich Anlass, die bislang nicht hinterfragte Annahme, die Ausdrücke,,reiner Verstandesbegriff" und,,Kategorie" seien bloß Synonyme, in Frage zu stellen.

Ever since Aristotle, ontology has been assumed to have a single meaning. Classic ontology branched into three directions established by Kant--the three chief manifestations of reality: cosmology, psychology, and theology--and in its quality of pure ontology became the study exclusively of being. On the other hand, the three dialectical branches have been losing their validity and are being replaced by regional ontologies which take explicit account of their several objects. Four territories today present themselves for intensive speculative cultivation; quantity, matter, (...) life, and spirit. Theology has returned to its classic position at the side of pure ontology. The ideas of object and of concept are radically opposite, but nevertheless are closely related in the context of knowledge; an object is the source of a concept. A concept is formed by one or several objective instances, but does not include all of them; there are more or less determinate objects, some of which have undergone conceptual modification while others remain quite obscure, all of which indicates that the world of reality is not so evident or firm as it appears to common sense. The ideas of being and of objects bring us again to the consideration of the metaphysical theme of the individual. Neither being nor object is the concrete individual; the problem of the individual remains involved in the whole problem of substance as it was discussed in classic metaphysics, because it was completely grounded in this metaphysics and is best discussed and appreciated as the problem of the incommunicable and subsistent. Regional ontology, in fixing its attention entirely on the object, thereby limits itself and makes clear its methodological orientation. Regional ontology by no means is to be considered as a theory of science; any theory, concrete or general is subject to a synthetic process in which facts and proofs immediately given incorporate the theory into the patrimony and positive achievements of intelligence. A theory is a scientific synthesis, and although its fundamental role is logical, its origin implies experimental functions. Regional ontology can be considered as a theory of objects, but its validation does not come from science itself; rather, it is the validation of scientific facts. Ontology might be called a theory a priori, but in that case the terms "theory" and "a priori" would be contradictory since the former requires experience and the latter renounces all experimental data. Ontology operates by means of general essences which objects of the same denomination have in common; thus we speak of the realm of quantity, the realm of matter, the realm of life, and the realm of spirit. The mathematical as well as the natural, biological, and spiritual sciences clearly have different objective planes which correspond to different ontological categories, which are foreign to the experiencing subject because it knows them only concretely as phenomena. The metaphysical basis of mathematics is quantity, a real accident of matter. Quantity examined according to the ontology of mathematics arises from matter, finding its origin in matter as the quality related to form. The ontology of the physicochemical sciences is concerned with the contents of quantity, with the internal object by which quantity is numbered and given its nature. Matter presents a problem to philosophy no less important than the problem it presents to the sciences whose data are mere approximations to matter. Natural sciences which seem very intelligible resolve themselves into a morass of questions when one tries to reduce them to science strictly so-called. In present-day philosophy we say that the nature and structure of objects and beings, both inorganic and organic, are in practice external to human action, taking "human" in the sense of spiritual being. The instability of living being, in contrast to the internal equilibrium of inanimate being, makes it appear less intelligible. On the plane of ontology of life, man is the central problem, even though he is one of the most definite and individualized of beings. Man's life culminates in freedom, which makes man a responsible being, in this respect resembling God. Though less unknown than mathematical, material, and biological objects, mental objects are more difficult and involve subtle and risky problems. The first great phenomenon offered to the philosophy which penetrates the field of the ontology of the social sciences is the identity between the object and the subject, since the subject, who as far as possible refers systematically to the pure object, continually treads the boundary of reality and arrives at himself; that is, the inquiring subject becomes simultaneously the object investigated--a kind of cognitive identity possible in reflection. The second problem of this field of philosophy is the consideration of "I" as absolutely empty of objectivity. For contemporary philosophy, spirit is the world of values, and it is not so important to determine the pure reality of spirit as to understand its life, its activity, and its specific manifestation which is the world of culture. The social sciences deal with man as a spiritual being, and with the facts of culture. The values produced by culture constitute a hierarchy which goes from the most humble to the most elevated, from plain economic interest to an intense desire for God. Culture is produced by the objectification of values; spirit becomes fixed in certain entities which are cultural objects: a theory, a machine, a concert. Man acts as the creator of a culture, but the culture in turn spiritually actuates and nourishes him. The sciences of spirit go from signs to their meaning, from the expression to the living. The point of departure in historical knowledge is our own vital experience, the very life which flows within us. Only life understands life. Here we find the reason why culture indicates the maximum expression of life; in culture, man contemplates himself, and in himself he contemplates all the beings of creation. (shrink)

Kant's theory of arithmetic is not only a central element in his theoretical philosophy but also an important contribution to the philosophy of arithmetic as such. However, modern mathematics, especially non-Euclidean geometry, has placed much pressure on Kant's theory of mathematics. But objections against his theory of geometry do not necessarily correspond to arguments against his theory of arithmetic and algebra. The goal of this article is to show that at least some important details in Kant's theory of arithmetic can (...) be picked up, improved by reconstruction and defended under a contemporary perspective: the theory of numbers as products of rule following construction presupposing successive synthesis in time and the theory of arithmetic equations, sentences or "formulas"—as Kant says—as synthetic a priori. In order to do so, two calculi in terms of modern mathematics are introduced which formalise Kant's theory of addition as a form of synthetic operation. (shrink)
