The effort of Fichte’s Foundations of the Entire Science of Knowledge is to ground the whole of the science in so called principles. This aim is a specific expression of the project of self-assurance of human being characterizing the important movement of modern metaphysics.
The movement towards self-assurance even culminates here: it gets a form of showing human being as an entity founding itself and in totality with itself the whole of actuality. The foundation of science is therefore in this Fichte’s work completely subordinated to the project of explicit self-constitution of human being based in practical-theoretical mastering of consciousness of its own ontological-ontical priority.
