  But can it be true that something, in this case motion, has happened, when it was never true to say of it ‘It is happening’? Yes, replies Diodorus (Sextus, 10.97–100): for example, ‘These men have married’ may be true despite the fact that there was never a time when it was true to say of them ‘These men are marrying,’ since they each married at a different time. This supporting argument, drawn from Diodorus’s logical arsenal, sits comfortably with the assumption that the staccato theory of motion really was his own doctrine. Although unmistakably in the tradition of Zeno of Elea, it is an attempt to make us re-analyse, rather than reject, phenomenal change.
