Maimonides Quote

Fourth Theory.—Man has free will; it is therefore intelligible that the Law contains commands and prohibitions, with announcements of reward and punishment. All acts of God are due to wisdom; no injustice is found in him, and he does not afflict the good. The Mu'tazila profess this theory, although they do not believe in man's absolute free will. They hold that God takes notice of the falling of the leaf and the destruction of the ant, and that his Providence extends over all beings.
