Berkeley and Kant are known for having developed philosophical critiques of materialism, critiques leading them to propose instead an epistemology based on the coherence of our mental representations. For all that the two had in common, however, Kant was adamant in distinguishing his own " empirical realism " from the immaterialist consequences entailed by Berkeley's attack on abstract ideas. Kant focused his most explicit criticisms on Berkeley's account of space, and commentators have for the most part decided that Kant either misunderstood or was simply unfamiliar with the Bishop's actual position. Rather than demonstrate that Kant understood Berkeley perfectly well—an argument that has already been forcefully made by Colin Turbayne—I want to take a different tack altogether. For it is by paying attention to Berkeley's actual account of space, an account oriented by his rejection of spatial " geometers " like Descartes, and spatial " absolutists " like Newton, that we discover an account of embodied cognition, of spatial distance and size that can only be known by way of the body's motion and touch. Perhaps even more striking, I will want to suggest, is the manner in which Kant's approach to the problem of incongruent counterparts will equally need to rely on a proprioceptive cognition, one requiring a different geometry of position altogether. My discussion proceeds in three stages, with stage one focused on Kant's efforts to distinguish his philosophical project from Berkeley's own idealist system, and stages two and three describing the manner in which their approach to spatial orientation both challenges and extends the traditional narrative of their differences as laid out in stage one.

The investigation that I am going to pursue here is part of a larger effort on my part to understand the relationship between Kant’s so-called “philosophical anthropology” and the development of early German anthropology since it is my sense that Kant had a determinate, if indirect, effect on the history of that separate field. For now this larger project has three main foci: an account of Kant’s philosophical anthropology in all its parts, an inquiry into Kant’s relationship to the theories engaged by German anthropologists between roughly the 1750s-1790s, and finally, an effort to track the subsequent routes taken by German anthropology in the first half of the 19th-c. In this discussion I am going look at one particular trajectory in anthropological research where we can see Kant’s effect.

Although scholarly attention has been mostly paid to the many connections existing between Kant and the exact sciences, the landscape of Kant studies has begun to noticeably change during the last decade, with many new pieces devoted to a consideration of Kant’s relation to the life sciences of his day. It is in this vein, for example, that investigators have begun to discuss the importance of Kant’s essays on race for the development of Anthropology as an emerging field. The bulk of the contributions to this recent trend, however, have focused on Kant’s remarks on organic life in the Critique of Judgment, such that Kant’s “theory of biology” is now seen to be firmly located in that text. Amidst such consolidation, there are a few pieces that have begun to address Kant’s appeal to organic vocabulary within the context of his theory of cognition, though these too remain dominated by the interpretive template set by the third Critique. My own strategy in this essay will be different. Kant did indeed borrow from the life sciences for his model of the mind, but in a manner that would reject a naturalized account. His preference for epigenesis as a theory of organic generation needs to be carefully distinguished, therefore, from the use he would make of it when discussing a metaphysical portrait of reason.

Focusing on the account of synthesis in Kant’s Transcendental Deduction allows us to see a greater degree of compatibility between the two editions of theCritique of Pure Reason than is sometimes thought. The first Deduction shows that while it emphasizes an account of empirical synthesis it also includes a more properly transcendental account of the synthetic unity required for cognition. The second edition simply focuses on this feature of synthesis to the exclusion of the empirical. The result: a complete account of synthesis with the A-edition starting “bottom up” from sense and the B-edition working “top-down” from thought.

This dissertation describes the development of Kant's transcendental idealism starting with the 1770 Inaugural Dissertation and continuing through to the 1787 second edition of the Critique of Pure Reason. My central argument is that transcendental idealism develops in response to the question concerning the relation between concepts and objects. In making this point I examine the emphasis placed on sense in the Dissertation, an emphasis demanding Kant's rejection of intellectual intuition, before moving to a discussion of Kant's famous letter to Marcus Herz. While the problem was thus exposed as early as 1772 it is only in 1781 that Kant is able to present his "Copernican revolution" in philosophy as the definitive solution. The second half of this study traces out the consequences of Kant's solution, specifically with respect to the charge of a Berkeleyan idealism.

The thirteen essays collected by Paul Guyer for Kant’s System of Nature and Freedom represent, with three exceptions dating from the early 1990’s, pieces either written or presented by Guyer since the year 2000. The one wholly new piece added to the collection nicely confirms an increasing sense throughout the volume of Guyer’s ultimate interest in Kant’s questions concerning right, morality, and our relationships and obligations towards nature and mankind. More than simply offering a reconstruction of Kant’s understanding of the system of nature and freedom, in this collection Guyer appears to be increasingly concerned with the possibilities for thinking through Kant towards a less restrictive liberal agenda. And with this agenda in mind one can say that, particularly with respect to the most recent essays, he has been quite successful. The book is suitable for any advanced students wishing for detailed and careful analyses of Kant’s notion of system, and certainly for anyone engaged in the niceties of Kant scholarship in general. Experts will, of course, have their quibbles, particularly with respect to parts two and three, but this is only right since these discussions are, to my mind, the richest.

Kant’s longstanding interests in science have been well-documented. There are numerous studies devoted to Kant’s early work on cosmology in his Universal Natural History and Theory of the Heavens (1755), and of course also to his interests in physics and his work on forces (1747), axial rotation (1754), the ages of the earth (1754), fire (1755), earthquakes (1756), winds (1757), and even to his discussion of volcanoes on the moon (1785). It is well-known, moreover, that part of Kant’s work in the Critique of Pure Reason (1781) was to ground the certainty of scientific claims against Hume’s skepticism, and that Kant’s program for securing our experience of the natural world extended to his later account of the Metaphysical Foundations of Natural Science (1786). Less well-known, however, is the realization that Kant’s apparent bias toward the hard sciences has lain rather more in the interests of Kant scholars, than in Kant himself.

Kant's 1772 letter to Markus Herz is celebrated for its marking the ‘Critical turn’ in Kant's thought, a turn that would move Kant away from the speculative metaphysics of the 1750s towards the Critical philosophy of 1781. It is here, seemingly for the first time, that Kant asks the question concerning the relationship between concepts and objects, telling his former pupil that the answer to this question ‘constitutes the key to the whole secret of hitherto still obscure metaphysics.’ For anyone interested in the development of Kant's thought this makes for exciting news since it is the posing of this question that marks Kant's first step towards the Critique and it is the answer to this question that will come to identify the ‘objective portion’ of the Transcendental Deduction, a text that already begins with a rehearsal of points raised in Kant's letter. But while the letter to Herz is clearly itself a key to what Kant sees as the ‘whole secret of hitherto still obscure metaphysics’, the question concerning concepts and objects itself poses interpretive problems that need to be addressed. Above all, one needs to ask how Kant arrived at such a question

This essay discusses Kant’s account of truth, arguing that he offers us a weak coherence theory: weak for his insistence on an independent, sensuous content for intuition, coherentist for the transcendental apparatus supporting experience. While Kant is free to use the language of correspondence within experience, “empirical truth” will always be limited by the formative requirements set by “transcendental truth.” The difficulty, for Kant, is the role played by sensuous content since the sameness of this content in intersubjective experience seems to point outside the conditions of synthesis to a transcendentally real object. While the consequence of this would seem to leave Kant in a contradiction—denying transcendental realism at the same time that he must affirm it—we must read Kant’s insistence on a merely negative use of noumena as evidence that he adopts the role of the skeptic as a means for maintaining his epistemic goals.

John Locke’s theory of classification is a subject that has long received scholarly attention. Little notice has been taken, however, of the problems that were posed for taxonomy by its inability to account for organic processes. Classification, designed originally as an exercise in logic, becomes complicated once it turns to organic life and the aims of taxonomy become entangled with processes of generation, variation, and inheritance. Locke’s experience with organisms—experience garnered through his work in botany and medicine—suggested to him both the dynamism of nature and the artificiality of any a priori system of classification. This reinforced Locke’s critique of classification in the Essay Concerning Human Understanding, and by tracing its influence it is possible to approach Locke’s nominalism from a fresh perspective.

This paper examines one of the central complaints regarding Locke’s Essay, namely, its supposed incoherence. The question is whether Locke can successfully maintain a materialistic conception of matter, while advancing a theory of knowledge that will constrain the possibilities for a cognitive accessto matter from the start. In approaching this question I concentrate on Locke’s account of unity. While material unity can be described in relation to Locke’s account of substance, real essence, and nominal essence, a separate discussion will be called for altogether in the case of organic unity. In closing, I turn to Kant as a model for locating Locke’s purported incoherence, suggesting that his “skeptical idealism” yields the same epistemic advantages as those won by Kant’s “empirical realism.”

Kant’s Organicism: Epigenesis and the Development of Critical Philosophy, traces the decisive role played by eighteenth century embryological research for Immanuel Kant’s theories of mind and cognition. I begin this book by following the course of life science debates regarding organic generation in England and France between 1650 and 1750 before turning to a description of their influence in Germany in the second half of the eighteenth century. Once this background has been established, the remainder of Kant’s Organicism moves to the influential role played by models of embryological development for Kant’s approach to understanding the cognitive processes responsible for the generation of knowledge, with special attention paid to Kant’s Precritical writings in the 1760s and 1770s. The book closes with a reinterpretation of Kant’s transcendental deduction in the Critique of Pure Reason.

Abstract: This essay addresses three specific moments in the history of the role played by intuition in Kant's system. Part one develops Kant's attitude toward intuition in order to understand how ‘sensible intuition’ becomes the first step in his development of transcendental idealism and how this in turn requires him to reject the possibility of an ‘intellectual intuition’ for human cognition. Part two considers the role of Jacobi when it came to interpreting both Kant's epistemic achievement and what were taken to be the outstanding problems of freedom's relation to nature; problems interpreted to be resolvable only via an appeal to ‘intellectual intuition’. Part three begins with Kant's subsequent return to the question of freedom and nature in his Critique of Judgment. With Goethe's contemporaneous Metamorphoses of Plants as a contrast case, it becomes clear that whereas Goethe can embrace the role of an intuitive understanding in his account of nature and within the logic of polarity in particular, Kant could never allow an intuition of nature that in his system would spell the very impossibility of freedom itself

This edited collection began as an international symposium on Kant and biology held at the University of Tübingen in 2010 and the now-published volume offers us new ways of thinking about Kant’s theory of biology with respect to not only his own work but to contemporary discussions regarding biological function and form. With a consistently high level of scholarship and a set of internationally renowned contributors, Kant’s Theory of Biology thus offers us an important contribution to the field’s rapidly growing interest in the history of the life sciences, and the book’s discussions devoted to the Critique of Judgement, in particular, will no doubt shape the course of subsequent investigations in the years to come. The anthology contains fifteen essays divided into three parts, with a focus on the development of the philosophy of biology in Kant’s early writings, the theory of organisms in Kant’s Critique of Judgement, and current perspectives on the teleology of nature. The quality of the editing on this book is excellent, far superior to that of a typical anthology, and what is to be especially appreciated is the helpful cross-referencing being done by the majority of the papers in so far as this lends the collection an organic, as opposed to a merely aggregative, feel.
