Abstract
Augustine has an argument which goes like this: Belief is assent; Assent is up to us: therefore Belief is up to us. The conclusion is-or was thought to be-a doctrine essential to Christian eschatology. The two premisses come from pagan philosophy. Sections I-II set out the argument and its background. Section III is theological. Section IV looks at the conclusion, with the help of Aristotle, while section V and VI look at the premisses. The last three sections of the paper consider some Stoic views pertinent to premiss , and the reply to those views offered by Alexander of Aphrodisias
