Such is the train of thought as stated for us in the Critique of Practical Reason.
His criticism of Wolff, which is generally based on sound sense, had much influence upon Kant at the time when his system was forming; and his ethical doctrines are mentioned with respect in the Kritik of Practical Reason.
But what is a postulate of practical reason to explain moral responsibility except a logical use of reason ?
Further, according to Fichte, on the one hand the Ego posits itself as determined through the non-Ego - no object, no subject; this is the principal fact about theoretical reason; on the other hand, the Ego posits itself as determining the non-Ego - no subject, no object; this is the principal fact about practical reason.
Fichte thus transformed the transcendental idealism of Kant by identifying the thing with the object, and by interpreting noumenon, not in Kant's sense of something which speculative reason conceives and practical reason postulates to exist in accordance with the idea, but in the new meaning of a thought, a product of reason.
