:cool: There's no wavey icon here, so that'll do instead.
Eh, it becomes tricky. I think this depends on how one thinks about rationalism actually, and how much Descartes to Hume could be said to be aware of "things-in-themselves".
Of course, though "synthesizing" rationalism and empiricism, one would have to say that, on the whole, Kant is very much in the rationalist camp in so far as he attributes to our mental powers so much more than Locke and Hume.
Though proceeded by others - clearly - the phenomena - things-in-themselves distinction is crucial here, as is the reigning in of speculative metaphysics. These arguments cause lots of arguments in favor and against.
Then you have, roughly, Humean, "empiricists", of a (to me) poorer quality than Hume's.
Descartes, generally, is not much praised these days, with few outliers, like Husserl and Chomsky.
The important thing to me and what I think makes Kant such an important figures, is that up to Kant, almost everyone agrees who the great philosophers were. Beyond him, there is no agreement, with the possible exception of the major American Pragmatists.
Marx, Nietzsche, Russell, Husserl, Heidegger, Quine, Carnap, Whitehead and others are extremely polarizing.
