 In the next few paragraphs of the Transcendental Aesthetic, Kant reaches the famous conclusions that we can speak of space “only from the human standpoint” (A26/B42) and that space has “transcendental ideality” (A28/B44). This is the heart of one of Kant’s main positions in the Critique of Pure Reason. In order to clarify these ideas, I first follow Kant’s suggestion in the passage above that he intends his position to be contrasted in some respects with the positions of Leibniz and of Newton. This maneuver will place us in a position to understand transcendental idealism in a bit more depth.
