X. The Annicereans, in many respects, agreed with these last; but they admitted the existence in life of friendship and gratitude and respect for one’s parents, and the principle of endeavouring to serve one’s country. On which principle, even if the wise man should meet with some annoyance, he would be no less happy—even though he should have but few actual pleasures. They thought that the happiness of a friend was not to be desired by us for its own sake; for that in fact such happiness was not capable of being felt by the person’s neighbour; and that reason is not sufficient to give one confidence, and to authorise one to look down upon the opinions of the multitude; but that one must learn a deference for the sentiments of others by custom, because the opposite bad disposition being bred up with infirm and early age. They also taught that one ought not to like friends solely on account of the advantage that we may derive from them, and not discard them when these hopes or advantages fail; but that we ought rather to cultivate them on account of one’s natural feelings of benevolence, in compliance with which we ought also to encounter trouble for their sakes, so that though they consider pleasure the chief good, and the deprivation of it an evil, still they think that a man ought voluntarily to submit to this deprivation out of his regard for his friend. XI. The Theodoreans, as they are called, derived their name from the Theodorus who has been already mentioned, and adopted all his doctrines. XII. Now Theodorus utterly discarded all previous opinions about the Gods: and we have met with a book of his which is entitled, On Gods, which is not to be despised; and it is from that that they say that Epicurus derived the principal portions of his sentiments. But Theodorus had been a pupil of Anniceris, and of Dionysius the Dialectician, as Antisthenes tells us in his Successions of Philosophers.
