An Inquiry into the Modern Prevailing Notions of the Freedom of the Will which is Supposed to be Essential to Moral Agency, Virtue and Vice, Reward and Punishment, Praise and Blame or simply The Freedom of the Will, is a work by Christian reformer, theologian, and author Jonathan Edwards which uses the text of Romans 9:16 as its basis. It was first published in 1754 and examines the nature and the status of humanity's will. The book takes the classic Calvinist viewpoint on total depravity of the will and the need of humanity for God's grace in salvation.
