“All soul is immortal. For that which is always in movement is immortal; that which moves something else, and is moved by something else, in ceasing from movement ceases from living. So only that which moves itself, because it does not abandon itself, never stops moving. But it is also source and first principle of movement for the other things which move. Now a first principle is something which does not come into being. For all that comes into being must come into being from a first principle, but a first principle itself cannot come into being from anything at all; for if a first principle came into being from anything, it would not do so from a first principle. Since it is something that does not come into being, it must also be something which does not perish. For if a first principle is destroyed, neither will it ever come into being from anything itself nor will anything else come into being from it, given that all things must come into being from a first principle. It is in this way, then, that that which moves itself is a first principle of movement. It is not possible for this either to be destroyed or to come into being, or else the whole universe and the whole of that which comes to be might collapse together and come to a halt, and never again have a source from which things will be moved and come to be. And since that which is moved by itself has been shown to be immortal, it will incur no shame to say that this is the essence and the definition of the soul”
