My aim in this essay is to lead the reader through the complexity of Hegel’s philosophical understanding of organic nature by highlighting its distinctive theoretical features and by examining these historically, both against the background of the approaches, achievements and trends of the empirical sciences of his time and in light of their scholarly reception.1 First, I focuss on Hegel’s definition of the ‘universal form’ of life, pointing to what the connection is, in his philosophy of nature, between the structure (...) of conceptual and living processes in the path to the individualization of matter. Second, since Hegel calls animal life “the truth of organics,” 2 I shall try to explain how in the philosophy of nature the Idea of life comes to differentiate itself into certain essential characteristics of immediate, finite and individual animals, passing through the stages of geological nature and vegetable organisms.
