ABSTRACT
This chapter discusses the arguments concerning principles (archai). Since most agree that some principles are material, while others are efficient, let us make the beginning (arche) of the argument with the efficient ones, since they say that these are more important than the material ones. And since most have declared that God is the most efficient cause, it first inquires into God, making it clear beforehand that, while following ordinary life undogmatically saying that there are gods, and honouring them, and saying that they have foreknowledge, peope none the less say the following things against the rashness of the Dogmatists. Sextus deploys the Diodoran argument to show that motion (indeed change in general) is impossible either on atomic or continuous hypotheses: if it moves in any way, it does so either (a) with the first part first, or (b) by occupying the whole divisible interval.
