There is a broad consensus in the literature that in the section on ‘The Genus’ in theScience of Logic, Hegel argues that any living being must exist among other instances of its kind, with which it reproduces to create future generations, and out of which it was itself produced. This view is not only hard to motivate philosophically, it also seems to contradict many things Hegel says elsewhere in his system about the details of living nature, especially concerning the reality of spontaneous generation. After an examination of the secondary literature on ‘The Genus’, I offer an alternative view of this section, which I call ‘the Modal Reading’. The Modal Reading sees the language of pluralities in ‘The Genus’ as really Hegel's peculiar way of articulating certain modal features of thoughts about the living: to grasp a living individual as living, we need to distinguish not only between this individual and its environment, but also between the things this individual actually does and other possibilities which it does not actualize. The Modal Reading has a logical motivation insofar as it articulates what is needed to think of a living being as living, but it also avoids saddling Hegel with the problematic entailments he is usually read as taking on in this section. A further upshot of the Modal Reading is that approaching Hegel in this way provides us with a way to see Hegel as defending a non-nominalistic alternative to essentialist accounts of living kinds. Finding a way to read ‘The Genus’ which coheres with Hegel's views elsewhere in his system thus shows Hegel to have been an especially subtle and penetrating thinker, with continuing relevance for the philosophy of biology.

The first part of the final section of Hegel's Science of Logic, the section on "The Idea", is titled "Life". Logic being the science of thought for Hegel, this section presents Hegel's account of the form of thought peculiar to thinking about living beings as living. Hegel's full account of this form of thought holds that a living being is (1) a functionally organized totality of members (2) that maintains itself in and through its environment (3) in the manner of some particular species. I develop Hegel's account in critical conversation with Kant's more limited principle, in the Critique of the Power of Judgement, for judging about internally purposive "natural ends" as beings in which every part is both means and end to every other. I argue that Hegel's view rationally develops from attempting to think through Kant's principle, retaining what is valuable in Kant's insights without treating the life sciences with skepticism.
