Getting Younger

I argue that in Plato’s 141 6– 4, things in time come to be simultaneously older and younger than themselves because a thing’s past and present selves are both real. As a result, whatever temporal relation is predicated of any of these past and present selves is true of the thing in question. Unlike other interpretations, this reading neither assumes that things in time have to replace their parts, nor that time is circular. I conclude that the passage is committed to a conception of the ongoing present and a rejection of presentism and endurantism in favour of a growing universe theory and perdurantism.
