I could identify for virtually every important figure in the history of modern continental philosophy an idea (or more than one) absolutely central to that philosopher's thought, whose original author was Fichte.

Being aware of truths about what is good or right or about what we ought to do is not the same as deciding what to do. Nor can the former truths be derived from decisions about what to do, or about procedures for making such decisions, unless these procedures themselves rest in some way on the apprehension of truths about what we ought to do.

Capitalism has not proven to be a transitional form, a gateway to a higher human future.

It is actually a nice question how far Descartes himself endorses the monological and metaphysically dualistic theory of mind associated with his name and his legacy in early modern philosophy. But Fichte does reject this tradition, by suggesting that an immaterial thinking substance is an incoherent notion, and a rational being whose rationality was not developed through communication with others is a transcendental impossibility.

Freedom is an unprovable but unavoidable presupposition, not an article of faith.

We commit not only theoretical error but also moral wrong in objectifying ourselves or other rational beings, ignoring their capacities for free action and communicative interaction with us.

Since the Enlightenment, popular religion has rejected the Enlightenment path and transformed itself into a bastion of resistance against reason.
