ABSTRACT
A priori - A posteriori I should like to start by saying something about apriorism. First, I do not want anyone to tell me what terminology I should use. The main thing is that the terminology is clear. And the term 'genetically a priori' is completely clear, in my view at least. It means that something already exists before the a posteriori, before any perception. Besides, it is necessary to keep using the term 'a priori' because precisely here there is a quite definite relation to Kantianism. In my opinion, Kant becomes much more intelligible if one is clear that, very often at least, he meant 'genetically a priori', although of course he always spoke of 'a priori valid'.
