If Socrates was born, Socrates became either when Socrates existed not or when Socrates already existed; but if he shall be said to have become when he already existed, he will have become twice; and if when he did not exist, Socrates was both existent and non-existent at the same time — existent through having become, non-existent by hypothesis. And if Socrates died, he died either when he lived or when he died. Now he did not die when he lived, since he would have been at once both alive and dead; nor yet when he died, since he would have been dead twice. Therefore Socrates did not die. And by applying this argument in turn to each of the things said to become or perish it is possible to abolish becoming and perishing.
— Sextus Empiricus
