Thomas Reid in the context of "Libertarianism (metaphysics)"

Metaphysical libertarianism is the philosophical view that free will exists, that it is incompatible with determinism, and therefore that determinism is false. In the branch of philosophy known as metaphysics, libertarianism is one of the main positions related to the problems of free will and determinism. In particular, libertarianism is an incompatibilist position which argues that free will is logically incompatible with a deterministic universe. Libertarianism states that since agents have free will, determinism must be false.

One of the first clear formulations of libertarianism is found in John Duns Scotus. In a theological context, metaphysical libertarianism was notably defended by Jesuit authors like Luis de Molina and Francisco Suárez against the rather compatibilist Thomism of Domingo Báñez. Other important metaphysical libertarians in the early modern period were René Descartes, George Berkeley, Immanuel Kant and Thomas Reid.
