I just can't get my head around what Kant means by "transcendental" in the term "transcendental idealism". Can you help? Also, Kant CAN"T be serious suggesting that we create space and time! If I create it, how did YOU get in my space-time and I in yours? After all, we're talking to, and recognizing each other. (Not sure I'm even understanding this really). Also, idealism seems, as Popper says somewhere, very anthropomorhic. We think we are so special, so crucial to reality. My, we are quite full of ourselves.---Baffled.

Transcendental idealism does not mean that we create our own ideas, but that we can only apply them to our experience. That is, we can only know they apply to our experience, since what counts as objective knowledge is defined in terms of them. We cannot say whether those ideas extend anywhere beyond our experience, that would be transcendent realism, and transcendental idealism is far less ambitious. It just claims that what we call an object has to be characterized by particular categories of thought and those categories can only be used by us to describe experience, nothing else.

It is anthropomorphic in the sense that the rules of what counts as an object for human beings is indeed limited to human beings. We are not crucial to reality, but what we call reality has to be based on our ideas of it. It is in fact a very restrictive and limited principle. We cannot say whether what we call objects really exist outside of our approach to the world, since our ideas stop at experience. Not a lot to be smug about there, I think.
