I'm reading Schelling's System of Transcendental Idealism, and in the end of the 3rd part (the end of the theoretical philosophy) schelling disproves the idea that a priori ideas are inherent in us from birth, and the idea that they come from an "original" flow (not sure or the correct term). After that he dismisses Malebranche and Berkeley's thoughts that the ideas originated in God.
Schelling then later on continues to state that all those mistaken conclusions can be resolved by the statement that the consciousness is neither a priori nor a postriori, when we see that the core of that seperation lies in the fact that the object of philosophy, the "I", is neither of those, which eliminates any objectiveness of a priori consciousness.
Now, I don't see Schelling disproves the concept of a priori ideas at all, in fact he relies deeply on that concept in his transcendental research. So I would like to ask, where DOES the a priori ideas lay?
