This paper argues that Hegel's depiction of knowledge, as presented in the Encyclopaedia philosophy of subjective Spirit, is founded on what he deems to be the practical interests of self-consciousness. More specifically, it highlights the significance of the will in Hegel's understanding of the cognitive process. I begin with a survey of the relation between category-formation and the notion of self-determining freedom in the Logic , and therewith draw attention to the unity of thinking and willing in the Concept. I (...) then indicate how Hegel's philosophy of subjective Spirit should be read as the applied logic of the Concept, according to which the socially constituted self-conscious I seeks to realise its claims to freedom through its theoretical cognitions of objects. As part of what could be called Hegel's integrative theory of the faculties, I finally argue that the will underscores both the determinate character of our theoretical cognitions and the reflexivity of knowledge in general. On this score, I maintain that Hegel, whose relation to Kant and Fichte I also consider, is of the view that it is with reference to willing that we can account for the self-referential nature of reason in toto as the actualised unity of theoretical-practical subjectivity.
