The primary challenge for generating a useful scientific definition of life comes from competing concepts of biological activity and our failure to make them explicit in our models. I set forth a three-part scheme for characterizing definitions of life, identifying a binary , a range , and a preference . The three components together form a proper activity in biology . To be clear, I am not proposing that proper activity be adopted as the best definition of life or even (...) as a desirable definition for life. Instead, I am arguing that some notion of proper activity already exists within common scientific definitions. By making the implicit elements explicit, the notion can be analyzed to see whether it is useful and appropriate in the context of the biological sciences. (shrink)

German Romanticism is a thinking of life as exposed. Philosophical conceptions of botanical life are paradigmatic of this. Goethe, Schelling, and Hegel each address the plant in their respective philosophies of nature. This article traces the connections and divergences in their thinking of plants, focusing on the role of love, lack, and exposure in order to present the plant as a peculiarly apt figure for considerations of life as exposed.

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.

By denying to vegetal life the core values of autonomy, individualization, self-identity, originality, and essentiality, traditional philosophy not only marginalizes plants but, inadvertently, confers on them a crucial role in the current transvaluation of metaphysical value systems. From the position of absolute exteriority and heteronomy, vegetation accomplishes a living reversal of metaphysical values and points toward the collapse of hierarchical dualisms.
