I recently asked a series of questions about ET, and this is one of them :)
Intuitively, it seems to me that ET is supposed to contradict Kant's (or more generally, the German Idealism's) Metaphysics (historically I've learned that's how it was, a heated debate between the both, with Darwin attacking Hegel's theories and Schelling defending).
But after learning more of the different opinions on ET, I thought it would be good to ask and see what people say about the subject.
The more specific subjects are
a) Kant's moral law
b) Hegel's History of Spirit.
[tell me if you think this should be separated into two questions.]
Edit:
For clarification, when I sat Kant's Metaphysics I mean both the thing-in-itself and the way our consciousness came to be, and the moral law.
