Libertarianism (metaphysics)

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.[4]

The task of the metaphysical libertarian is to reconcile free will with indeterminism

One of the first clear formulations of libertarianism is found in John Duns Scotus. In theological context, metaphysical libertarianism was notably defended by Jesuit authors like Luis de Molina and Francisco Suárez against rather compatibilist Thomist Bañecianism. Other important metaphysical libertarians in the early modern period were René Descartes, George Berkeley, Immanuel Kant and Thomas Reid.[5]

Roderick Chisholm was a prominent defender of libertarianism in the 20th century[6] and contemporary libertarians include Robert Kane, Peter van Inwagen and Robert Nozick.
