The Refutation of All Heresies

The Stoics themselves also imparted growth to philosophy, in respect of a greater development of the art of syllogism, and included almost everything under definitions, both Chrysippus and Zeno being coincident in opinion on this point. And they likewise supposed God to be the one originating principle of all things, being a body of the utmost refinement, and that His providential care pervaded everything; and these speculators were positive about the existence of fate everywhere, employing some such example as the following: that just as a dog, supposing him attached to a car, if indeed he is disposed to follow, both is drawn, or follows voluntarily, making an exercise also of free power, in combination with necessity, that is, fate; but if he may not be disposed to follow, he will altogether be coerced to do so.

And the same, of course, holds good in the case of men. For though not willing to follow, they will altogether be compelled to enter upon what has been decreed for them. (The Stoics), however, assert that the soul abides after death, but that it is a body, and that such is formed from the refrigeration of the surrounding atmosphere; wherefore, also, that it was called psyche (i.e., soul). And they acknowledge likewise, that there is a transition of souls from one body to another, that is, for those souls for whom this migration has been destined.

And they accept the doctrine, that there will be a conflagration, a purification of this world, some say the entire of it, but others a portion, and that (the world) itself is undergoing partial destruction; and this all but corruption, and the generation from it of another world, they term purgation. And they assume the existence of all bodies, and that body does not pass through body, but that a refraction takes place, and that all things involve plenitude, and that there is no vacuum. The foregoing are the opinions of the Stoics also.
