[8] However, Democritus and Epicurus, and the principal number of the Stoic philosophers, affirm both the creation and the destructibility of the world, though they do not all speak in similar senses; for some give a sketch of many worlds, the generation of which they attribute to the concourse and combination of atoms, and their destruction they impute to the dissolution and breaking up of the combined particles. But the Stoics speak of one world only, and affirm that God is the cause of its creation, but that the cause of its corruption is no longer God, but the power of invincible, unwearied fire, which pervades all existing things, in the long periods of time dissolving everything into itself, while from it again a regeneration of the world takes place through the providence of the Creator.
