obligation, it was in our power to prevent or put an end to their calamity, it undoubtedly was our duty to do so. The propriety of action, the rule which Jupiter had given us for the direction of our conduct, evidently required this of us. But if it was altogether out of our power to do either, we ought then to consider this event as the most fortunate which could possibly have happened: because we might be assured that it tended most to the prosperity and order of the whole, which was that we ourselves, if we were wise and equitable, ought most of all to desire. It was our own final interest considered as a part of that whole, of which the prosperity ought to be, not only the principal, but the sole object of our desire. 'In what sense,' says Epictetus, 'are some things said to be according to our nature, and others contrary to it? It is in that sense in which we consider ourselves as separated and detached from all other things. For thus it may be said to be according to the nature of the foot to be always clean. But if you consider it as a foot, and not as something detached from the rest of the body, it must behove it some times to trample in the dirt, and sometimes to tread upon thorns, and sometimes, too, to be cut off for the sake of the whole body; and if it refuses this, it is no longer a foot. Thus, too, ought we to conceive with regard to ourselves. What are you? A man. If you consider yourself as something separated and detached, it is agreeable to your nature to live to old age, to be rich, to be in health. But if you consider yourself as a man, and as a part of a whole, upon account of that whole, it will behove you sometimes to be in sickness, sometimes to be exposed to the inconveniency of a sea voyage, sometimes to be in want, and at last perhaps to die before your time. Why then do you complain? Do not you know that by doing so, as the foot ceases to be a foot, so you cease to be man?'
