Principal Doctrine 39

XXXIX "He who desires to live in tranquility with nothing to fear from other men ought to make friends. Those of whom he cannot make friends, he should at least avoid rendering enemies; and if that is not in his power, he should, as much as possible, avoid all dealings with them, and keep them aloof, insofar as it is in his interest to do so" (Epicurus, Principal Doctrine 39)
