Abstract

This paper presents Fichte’s system of philosophical science with the aim of elucidating the boundary separating the pure, absolute I and the empirical, individual I in the system. Tapping on writings related to the two versions of the Jena Doctrine of Science, I represent Fichte’s philosophical project as the primarily epistemological one of maintaining the scientific status of pre-philosophical knowledge in the face of the Maimonian skeptical challenge. Apparently, Fichte analyzes the scientificity of a body of knowledge in terms of its certainty and systematicity. But it is in connection with his conception of a philosophical-scientific system as a presentation of an autonomous “system of a human mind” that we are able to make sense of the systematicity and certainty that are at play in the concept. Moreover, the philosophical-scientific system falls short of meeting the Maimonian skeptical challenge so long as it remains incomplete. Most importantly, the human-mental system is no empirical subject, but a pure subject that maps the possible perceptions and actions which an empirical subject has the potential to realize for itself.
