(It is proper also to bear in mind how many discourses have been devoted by men in the past to show that man is by nature a social animal. And shall we, after, asserting this and enjoining it, bear ourselves unsociably to our neighbours? Then let everyone make the basis of his conduct moral virtues, and actions like these, namely reverence towards the gods, benevolence towards men, personal chastity; and thus let him abound in pious acts, I mean by endeavouring always to have pious thoughts about the gods, and by regarding the temples and images of the gods with due honour and veneration, and by worshipping the gods as though he saw them actually present. For our fathers established images and altars, and the maintenance of undying fire, and, generally speaking, everything of the sort, as symbols of the presence of the gods, not that we may regard such things as gods, but that we may worship the gods through them. For since being in the body it was in bodily wise that we must needs perform our service to the gods also, though they are themselves without bodies; they therefore revealed to us in the earliest images the class of gods next in rank to the first, even those that revolve in a circle about the whole heavens. But since not even to these can due worship be offered in bodily wise—for they are by nature not in need of anything(509)—another class of images was invented on the earth, and by performing our worship to them we shall make the gods propitious to ourselves. For just as those who make offerings to the statues of the emperors, who are in need of nothing, nevertheless induce goodwill towards themselves thereby, so too those who make offerings to the images of the gods, though the gods need nothing, do nevertheless thereby persuade them to help and to care for them. For zeal to do all that is in one’s power is, in truth, a proof of piety, and it is evident that he who abounds in such zeal thereby displays a higher degree of piety; whereas he who neglects what is possible, and then pretends to aim at what is impossible, evidently does not strive after the impossible, since he overlooks the possible. For even though God stands in need of nothing, it does not follow that on that account nothing ought to be offered to him. He does not need the reverence that is paid in words. What then? Is it rational to deprive him of this also? By no means. It follows then that one ought not to deprive him either of the honour that is paid to him through deeds, an honour which not three years or three thousand years have ordained, but all past time among all the nations of the earth.)
