Kant’s philosophy of science takes on sharp contour in terms of his interaction with the practicing life scientists of his day, particularly Johann Blumenbach and the latter’s student, Christoph Girtanner, who in 1796 attempted to synthesize the ideas of Kant and Blumenbach. Indeed, Kant’s engagement with the life sciences played a far more substantial role in his transcendental philosophy than has been recognized hitherto. The theory of epigenesis, especially in light of Kant’s famous analogy in the first Critique, posed crucial (...) questions regarding the ‘looseness of fit’ between the constitutive and the regulative in Kant’s theory of empirical law. A detailed examination of Kant’s struggle with epigenesis between 1784 and 1790 demonstrates his grave reservations about its hylozoist implications, leading to his even stronger insistence on the discrimination of constitutive from regulative uses of reason. The continuing relevance of these issues for Kant’s philosophy of science is clear from the work of Buchdahl and its contemporary reception. (shrink)

Gayon's recent claim that Buffon developed a concept of species as physical individuals is critically examined and rejected. Also critically examined and rejected is Gayon's more central thesis that as a consequence of his analysis of Buffon's species concept, and also of Darwin's species concept, it is clear that modern evolutionary theory does not require species to be physical individuals. While I agree with Gayon's conclusion that modern evolutionary theory does not require species to be physical individuals, I disagree with (...) his reasons and instead provide logical rather than historical reasons for the same conclusion.

Though it did not yet exist as a discrete field of scientific inquiry, biology was at the heart of many of the most important debates in seventeenth-century philosophy. Nowhere is this more apparent than in the work of G. W. Leibniz. In Divine Machines, Justin Smith offers the first in-depth examination of Leibniz's deep and complex engagement with the empirical life sciences of his day, in areas as diverse as medicine, physiology, taxonomy, generation theory, and paleontology. He shows how these (...) wide-ranging pursuits were not only central to Leibniz's philosophical interests, but often provided the insights that led to some of his best-known philosophical doctrines.Presenting the clearest picture yet of the scope of Leibniz's theoretical interest in the life sciences, Divine Machines takes seriously the philosopher's own repeated claims that the world must be understood in fundamentally biological terms. Here Smith reveals a thinker who was immersed in the sciences of life, and looked to the living world for answers to vexing metaphysical problems. He casts Leibniz's philosophy in an entirely new light, demonstrating how it radically departed from the prevailing models of mechanical philosophy and had an enduring influence on the history and development of the life sciences. Along the way, Smith provides a fascinating glimpse into early modern debates about the nature and origins of organic life, and into how philosophers such as Leibniz engaged with the scientific dilemmas of their era.

This intellectual biography of Immanuel Kant's early years--from 1747 when his first book was published, to 1770 when his Critique of Pure Reason was about to be printed--makes an outstanding contribution to Kant scholarship. Schonfeld meticulously examines almost all of Kant's early works, summarizes their content, and exhibits their shortcomings and strengths. He places the early theories in their historical context and describes the scientific discoveries and philosophical innovations that distinguish Kant's pre-critical works. Schonfeld argues that these works were all (...) aspects of a single project carried out by Kant to reconcile metaphysical and scientific perspectives and combine them into a coherent model of nature.

Sloan - Performing the Categories: Eighteenth-Century Generation Theory and the Biological Roots of Kant's A Priori - Journal of the History of Philosophy 40:2 Journal of the History of Philosophy 40.2 229-253 Preforming the Categories: Eighteenth-Century Generation Theory and the Biological Roots of Kant's A Priori Phillip R. Sloan Situating Kant's philosophical project in relation to the natural sciences of his day has been of concern to several scholars from both the history of science and the history of (...) philosophy. Historians of philosophy have displayed an expanded awareness of, and interest in, the importance of the scientific context of the period in which Kant carried out his "Copernican" revolution. Most commonly among philosophers, this interest has been analyzed in relation to Kant's concerns with the foundations of mechanics, matter theory, and the epistemology of Newtonian science, with the central text of interest being the Metaphysische Anfangsgründe. On the other hand, historians of philosophy and historians of science, interested in the issues of the third Critique and in the several papers of Kant dealing with biological and anthropological issues, have emphasized the unified nature of Kant's inquiries into the natural sciences, and the importance of his continued interest in the life and human sciences alongside his interests in the foundations of the physical sciences. The effort to understand the unity of Kant's.. (shrink)

Since the 1970s, there has been a tremendous amount of literature on Ghiselin's proposal that species are individuals. After recalling the origins and stakes of this thesis in contemporary evolutionary theory, I show that it can also be found in the writings of the French naturalist Buffon in the 18th Century. Although Buffon did not have the conception that one species could be derived from another, there is an interesting similarity between the modern argument and that of Buffon regarding the (...) individuality of species. The analogy is strong enough to force us to recognize that genuine evolutionary (or Darwinian) questions might be of secondary importance in the discussion. In consequence, the third section of the paper proposes an alternative schema for the logical structure of the Darwinian concept of species. Darwin distinguished the problem of the designation of a concrete species, and the problem of its signification of species within his theory of descent? The resulting notion of species involves a logical structure based on the fusion of the logical operations of classification and ordering. The difficulty — and interest — is that this interpretation of species does not entail any precise operational definition of species; it can only tell us what the ultimate signification of classification is within the theory of descent with modification through natural selection.

Malebranche is both an occasionalist and an advocate of the preformationist theory of generation. One might expect this given that he is a mechanist: passive matter cannot be the source of its own motion and so requires God to move it (occasionalism); and such matter, moving according to a few simple laws of motion, could never fashion something as complex as a living being, and so organisms must be fashioned by God at Creation (preformationism). This expectation finds a challenge in (...) Kant's depiction of the relation between causation and generation. According to Kant, preformation is the generation theory one would expect the advocate of the pre-established harmony to endorse, while the occasionalist would endorse a theory whereby God directly forms the organism upon every insemination. I make sense of Malebranche's position in light of Kant's suggestion by examining the relation Malebranche sees between science and metaphysics, the roles that he believes empirical investigations and final causes have in scientific practice and explanation, and the role of the supernatural in Malebranche's philosophy.

It is beyond the scope of this paper to describe in detail the rise to popularity of the emboîtement theories during the last decades of the seventeenth century.51 Eventually the theories did gain great influence, but some points emerging from the above discussion indicate that the rise to popularity was not, perhaps, quite as rapid as has sometimes been assumed.52 Although the earlier preformation theories were sometimes regarded as the ancestors of the later ideas,53 there was little intellectual continuity between (...) the two movements, based as they were upon such divergent motivations. Nor can the preformation theories be regarded as the origin of the belief that a miniature can actually be seen within the egg, since the existence of metamorphosis as a perfectly valid alternative to epigenesis meant that the work of Malpighi and others, usually described as “preformationist,” was not always taken in this latter sense at the time it was published. The pre-existence theories developed in response to particular philosophical problems, and were themselves responsible for the reinterpretation of the observations. In France, the thoughts of Malebranche and Perrault were probably already exerting influence before their written support for pre-existence appeared, but elsewhere the idea was not taken up so rapidly, and ovism, for instance, could develop without associating itself with emboîtement. Malpighi always seems to have remained opposed to pre-existence,54 but by the last decade of the century, the idea had become sufficiently powerful to influence Ray and Garden in Britain, and was receiving support from as influential a thinker as Leibniz.55 But Garden and Hartsoeker were responsible for dividing emboîtement between two schools, just as the concept itself was becoming popular. The work of both Malpighi and Leeuwenhoek served as the basis of the animalculist version, illustrating how the microscopic discoveries served as much to disrupt the intellectual development of the emboîtement concept as they did to promote it. *** DIRECT SUPPORT *** A8402051 00002.

Contemporary philosophers frequently assume that Kant never seriously engaged with Spinoza or Spinozism --certainly not before the break of Der Pantheismusstreit, or within the Critique of Pure Reason. Offering an alternative reading of key pre-critical texts and to some of the Critique's most central chapters, Omri Boehm challenges this common assumption. He argues that Kant not only is committed to Spinozism in early essays such as "The One Possible Basis" and "New Elucidation," but also takes up Spinozist metaphysics as Transcendental (...) Realism's most consistent form in the Critique of Pure Reason. (shrink)
