"Also the difference of unsentient things from one another, the world with its five divisions.
"This same is real and from all eternity; if it had had a beginning it would have an end:
"Whereas it does not come to an end; and it is not illusorily imagined:
"For if it were imagined it would cease, but it never ceases.

"Two are these persons in the universe, the perishable and the imperishable;
"The perishable is all the elements, the imperishable is the unmodified.
