Libertarianism is one of the main philosophical positions related to the problems of free will and determinism which are part of the larger domain of metaphysics.[1] In particular, libertarianism is an incompatibilist position[2][3] which argues that free will is logically incompatible with a deterministic universe. Libertarianism states that since agents have free will, determinism must be false and vice versa.[4]
