In describing Kant's idea of the "thing-in-itself" Thomas Pogge (in response to a recent question on this site) recently wrote that "According to this explanation, space and time are then features only of objects as they appear to us." I'm having a difficult time deciphering this statement. To me when you speak of a feature of an object you are referring to that object in-itself almost by definition. It seems like space and time could be either a feature of the world or a feature of our mind/cognition or psychic tendencies which we project onto the world but not both. To say that space/time is a feature of the world as it appears seems to involve a confusion of how language is used to speak about being. Appearances can reveal or distort being but I don't see how they can contribute to being. We don't speak of colors as features of the (outer) world as they appear to us do we? We try to figure whether colors originate in the mind or in the world and though we allow that there is some degree of interaction between the world and our faculties it is still in some ultimate sense one or the other.
