"I will tell you," said I, "what seems to me; for philosophy is, in fact, the greatest possession, and most honourable before God, to whom it leads us and alone commends us; and these are truly holy men who have bestowed attention on philosophy. What philosophy is, however, and the reason why it has been sent down to men, have escaped the observation of most; for there would be neither Platonists, nor Stoics, nor Peripatetics, nor Theoretics, nor Pythagoreans, this knowledge being one. I wish to tell you why it has become many-headed. It has happened that those who first handled it, and who were therefore esteemed illustrious men, were succeeded by those who made no investigations concerning truth, but only admired the perseverance and self-discipline of the former, as well as the novelty of the doctrines; and each thought that to be true which he learned from his teacher: then, moreover, those latter persons handed down to their successors such things, and others similar to them; and this system was called by the name of him who was styled the father of the doctrine...."
I have previously discussed the Middle Platonist background to St. Justin's ideas.
