Kant’s theory of biology in the Critique of the Power of Judgment may be rejected as obsolete and attacked from two opposite perspectives. In light of recent advances in biology one can claim contra Kant, on the one hand, that biological phenomena, which Kant held could only be explicated with the help of teleological principles, can in fact be explained in an entirely mechanical manner, or on the other, that despite the irreducibility of biology to physico-mechanical explanations, it is nonetheless (...) proper science. I argue in response that Kant’s analysis of organisms is by no means obsolete. It reveals biology’s uniqueness in much the same way as several current theorists do. It brings to the fore the unique purposive characteristics of living phenomena, which are encapsulated in Kant’s concept of “natural end” and which must be explicated in natural terms in order for biology to become a science. I maintain that Kant’s reluctance to consider biology proper science is not a consequence of his critical philosophy but rather of his inability to complete this task. Kant lacked an appropriate theoretical framework, such as provided later by modern biology, which would enable the integration of the unique features of biology in an empirical system. Nevertheless, as I show in this paper, the conceptual problems with which Kant struggled attest more to the relevance and depth of his insights than to the shortcomings of his view. His contribution to the biological thought consists in insisting on an empirical approach to biology and in providing the essential philosophical underpinning of the autonomous status of biology.

We outline an alternative to both scientific and liberal naturalism which attempts to reconcile Sellars’ apparently conflicting commitments to the scientific accountability of human nature and the autonomy of the space of reasons. Scientific naturalism holds that agency and associated concepts are a mechanical product of the realm of laws, while liberal naturalism contends that the autonomy of the space of reason requires that we leave nature behind. The third way we present follows in the footsteps of German Idealism, which (...) attempted to overcome the Kantian chasm between nature and agency, and is thus dubbed ‘post-Kantian.’ We point to an overlooked group of scholars in the naturalism debate who, along with recent work in biology and cognitive science, offer a path to overcome the reductive tendencies of empiricism while avoiding the dichotomy of logical spaces. We then bring together these different streams of research, by foregrounding and expanding on what they share: the idea of organisms as living agents and that of a continuity without identity between life and mind. We qualify this as a bottom-up transformative approach to rational agency, which grounds cognition in the intrinsically purposive nature of organisms, while emphasizing the distinction between biological agency and full-fledged mindedness.

This thesis defines the philosophical concept of speculation and assessesits emergence in Kantian and post-Kantian German philosophy, in the attempted construction of a post-Enlightenment “scientific” philosophy and alongside early work in anthropology and gynaecology. It argues that in the historical elaboration of the problem of speculation “race” and “sex” emerge as concerns for this newly defined scientific philosophy. Moreover, a concept of performativity is introduced in the attempt to think the ontological implications or “effects” of speculative thought. This thesis proposes (...) that Hegel is the originator of such a concept of performativity, introduced as the conclusion to the Science of Logic. Here, performativity is defined as activity of form or determinate being in contrast to the empty notion of being pure being with which the Logic begins. Speculation, the Logic proposes, is not only a methodological necessity giving rise to an essentially epistemological problem, as Kant had defined it, but is also to be thought as ontological Thätigkeit proper. Rewriting speculation as an ontological concept of form, Hegel uses, among others, social and political examples to illustrate the nature of speculative thought. The surprising appearance of the state and the sexual relation in the Logic, alongside the concepts of violence, resistance, power and freedom, demonstrates that speculative reason necessarily encounters political categories and suggests that these might be exemplary of its nature. While it remains unclear, in Hegel, precisely how the unfolding of conceptual form leads to political categories, both Irigaray and Butler offer answers to this question. In doing so, they separately outline ways of thinking the ontological dimension of speculative thought: Irigaray by modifying speculation as speculation – an attempt to visualise speculation and to render its social dimensions visible; and Butler by formulating the concept of gender performativity. This thesis offers its own answer, too, by situating the emergence of speculation and performativity as philosophical concepts in the context of the history of modern gynaecology and the speculum. It reads these concepts alongside those of sexual difference, Geschlecht and gender, arguing that only in this way can speculation and performativity be thought. (shrink)
