 His study of the writings of K. L. Reinhold convinced Fichte that the systematic unity of the Critical philosophy—specifically, the unity of theoretical and practical reason, of the First and Second Critiques—was insufficiently evident in Kant’s own presentation of his philosophy and that the most promising way to display the unity in question would be to provide both theoretical and practical philosophy with a common foundation. The first task for philosophy, Fichte therefore concluded, is to discover a single, self-evident starting point or first principle from which one could then somehow “derive” both theoretical and practical philosophy, which is to say, our experience of ourselves as finite cognizers and as finite agents. Not only would such a strategy guarantee the systematic unity of philosophy itself, but, more importantly, it would also display what Kant hinted at but never demonstrated: viz., the underlying unity of reason itself.
