All this care for the world, we must believe, is taken by the Gods without any act of will or labor. As bodies which possess some power produce their effects by merely existing: e.g. the sun gives light and heat by merely existing; so, and far more so, the providence of the Gods acts without effort to itself and for the good of the objects of its forethought. This solves the problems of the Epicureans , who argue that what is divine neither has trouble itself nor gives trouble to others.
