Abstract

This paper discusses the views of three medieval thinkers—Anselm, Thomas Aquinas, and John Duns Scotus—about a specific aspect of the problem of evil, which can be dubbed ‘the Lucifer problem’. What was the object of the first evil choice? What could entice a perfectly rational agent placed in ideal circumstances into doing evil? Those thinkers agreed that Lucifer wanted to be happier, but while Anselm thought that that was something Lucifer could achieve by his natural powers, Aquinas held that it was not naturally possible for Lucifer to be happier, even though it was something he could obtain supernaturally. By contrast, Scotus posited that what Lucifer wanted was beyond what was logically possible, i.e. to be as happy as God (or to be God’s equal). An interesting consequence of Scotus’s hypothesis is that God could have done nothing to make Lucifer’s evil choice less likely.
