The philosopher Zeno proposed a paradox. ‘If
one is to run from one place to another, one must first get half-way. Before
that, one must get a quarter-of-the-way, and before that an eighth-of-the-way,
and so on. Indeed, one must traverse an infinite number of finite distances,
which cannot be done. Therefore, there is no motion.’
Diogenes the Cynic responded to this by
getting up and walking.
