True.
Then, that which becomes older than itself, also becomes at the same time younger than itself, if it is to have something to become older than.
What do you mean?
I mean this:—A thing does not need to become different from another thing which is already different; it IS different, and if its different has become, it has become different; if its different will be, it will be different; but of that which is becoming different, there cannot have been, or be about to be, or yet be, a different—the only different possible is one which is becoming.
That is inevitable.
But, surely, the elder is a difference relative to the younger, and to nothing else.
True.
Then that which becomes older than itself must also, at the same time, become younger than itself?
Yes.
But again, it is true that it cannot become for a longer or for a shorter time than itself, but it must become, and be, and have become, and be about to be, for the same time with itself?
