According to Kant, we think of ourselves as having free will. This lets us make judgments such as “you ought to have done that thing that you did not do.” Kant argues that this notion of freedom cannot be derived from our experience. We can be sure that this concept of freedom doesn't come from experience because experience itself contradicts it. Our experience is of everything in the sensible world and in the sensible world, everything that happens does so in accord with the laws of nature and there is no room for a free will to influence events.
