37 But this is the state of the case, that as you are exceedingly strong in war and in military power, you think you excel in knowledge of the truth also, and are pious before the gods, whose might you have been the first to besmirch with foul imaginings. Here, if your fierceness allows. and madness suffers, we ask you to answer us this: Whether you think that anger finds a place in the divine nature, or that the divine blessedness is far removed from such passions?
For if they are subject to passions so furious, and are excited by feelings of rage as your imaginings suggest.— for you say that they have often shaken the earth with their roaring, and bringing woeful misery on men, corrupted with pestilential contagion the character of the times, both because their games had been celebrated with too little care, and because their priests were not received with favour, and because some small spaces were desecrated, and because their rites were not duly performed—it must consequently be understood that they feel no little wrath on account of the opinions which have been mentioned.
But if, as follows of necessity, it is admitted that all these miseries with which men have long been overwhelmed flow from such fictions, if the anger of the deities is excited by these causes, you are the occasion of so terrible misfortunes, because you never cease to jar upon the feelings of the gods, and excite them to a fierce desire for vengeance. But if, on the other hand, the gods are not subject to such passions, and do not know at all what it is to be enraged, then indeed there is no ground for saying that they who know not what anger is are angry with us, * and they are free from its presence, and the disorder it causes.
For it cannot be, in the nature of things, that what is one should become two; and that unity, which is naturally uncompounded, should divide and go apart into separate things.
