Let us admit that the universal Soul is not in time; why should she
beget time rather than eternity? Because the things she begets are
comprised within time, instead of being eternal. Neither are the
other souls within time; nothing of them, except their "actions and
reactions" (Stoic terms). Indeed, the souls themselves are eternal;
and therefore time is subsequent to them. On the other hand, what is in
time is less than time, since time must embrace all that is within it,
as Plato says, that time embraces all that is in number and place.
