 These distinctions, according to Kant, allow us to resolve the “antinomy” about free will by interpreting the “thesis” that free will is possible as about noumena and the “antithesis” that every event has a cause as about phenomena. Morality thus presupposes that agents, in an incomprehensible “intelligible world,” are able to make things happen by their own free choices in a “sensible world” in which causal determinism is true.
