"Determinism, Chance and Freedom," for IVP Dictionary of Apologetics.
Determinists believe that every event (or every event in a certain category) has a cause that makes it happen exactly as it happens. Among the varieties of determinism are the views of (1) Plato, who held that one's ethical choices are determined by his view of what is good, (2) B. F. Skinner, who believed that stimuli, dispositions and motives govern all human behavior. (3) Democritus, Hobbes, Spinoza, and many others, who have held that every event in the universe is determined by a physical cause. Of special interest to us are (4) theological determinists, who hold that all events occur exactly as God has foreordained them. These would include Calvin and others in his tradition. The classic exposition of theological determinism is Jonathan Edwards' Freedom of the Will. Note that it is possible to be a determinist in sense (4) without being a determinist in sense (3). That seems to be the position of the Westminster Confession of Faith, which says in 3.1 that "God did... ordain whatsoever comes to pass," but also says in 9.1 that man's will "is neither forced, nor, by any absolute necessity of nature, determined to good, or evil" (compare 5.2).
