 All these are teachings that are very close to those of Avicenna (Frank 1992, 24–25). Al-Ghazâlî also followed Avicenna in his conviction that this universe is the best of all possible worlds and that “there is in possibility nothing more wondrous than what is” (laysa fî-l-imkân abda’ mimmâ kân) (al-Ghazâlî 1937–38, 13:2515–18 = 2001, 47–50). This led to a long-lasting debate among later Muslim theologians about what is meant by this sentence and whether al-Ghazâlî is, in fact, right (Ormsby 1984). It must be stressed, however, that contrary to Avicenna—and contrary to Frank’s (1992, 55–63) understanding of him—al-Ghazâlî firmly held that God exercises a genuine free will and that when He creates, He chooses between alternatives. God’s will is not in any way determined by God’s nature or essence. God’s will is the undetermined determinator of everything in this world.
