The Stoics Are Going Further Than Aristotle's Metaphysics

Aristotle did invoke an immaterial god as the primary cause of his cosmos. Yet the stoics too included god in their vision of the cosmos. In fact, they quite literally saw him aphysical being that pervades all things. The sense in which god is fire is more that he is physically subtle and active. He does not just pervade the cosmos, but wisely and artfully builds it from within.
