Can someone explain synthetic a priori as defined by Immanuel Kant to me? I've been reading up on various web pages but still don't get it. What I understood so far:
a priori: the proposition is not based on experience or perception.
synthetic: the truth value of the proposition isn't immediatly apparent and needs verification from the real world.
Somehow I don't see how those two go toghether...
I need some examples... anyone?
Thanks!
