 Kant concluded that certain big-ticket questions of metaphysics were impossible to settle, and he compiled a list of such questions, calling them, in fancy terms, the antinomies of critical reason. By antinomy, he means a question which critical reason was incapable of settling one way or the other. One must remain agnostic on these points, or these questions. Whether the world had a beginning in time, or whether it was eternal, whether the soul was immortal, or whether it ceased to exist with death, whether the will was genuinely free, or whether its experience of freedom was illusory, and lastly and most importantly for our concerns, whether God exists. Kant maintained that the answers to these questions can never be known by man.
