The Stoics, in the few fragments of their philosophy which have come down to us, sometimes talk of leaving life with a gaiety, and even with a levity, which, were we to consider those passages by themselves, might induce us to believe that they imagined we could with propriety leave it whenever we had a mind, wantonly and capriciously, upon the slightest disgust or uneasiness. “When you sup with such a person,” says Epictetus, “you complain of the long stories which he tells you about his Mysian wars. ‘Now my friend,’ says he, ‘having told you how I took possession of an eminence at such a place, I will tell you how I was besieged in such another place.’ But if you have a mind not to be troubled with his long stories, do not accept of his supper. If you accept of his supper, you have not the least pretence to complain of his long stories. It is the same case with what you call the evils of human life. Never complain of that of which it is at all times in your power to rid yourself.” Notwithstanding this gaiety and even levity of expression, however, the alternative of leaving life, or of remaining in it, was, according to the Stoics, a matter of the most serious and important deliberation. We ought never to leave it till we were distinctly called upon to do so by that superintending Power which had originally placed us in it. But we were to consider ourselves as called upon to do so, not merely at the appointed and unavoidable term of human life. Whenever the providence of that superintending Power had rendered our condition in life upon the whole the proper object rather of rejection than of choice; the great rule which he had given us for the direction of our conduct, then required us to leave it. We might then be said to hear the awful and benevolent voice of that divine Being distinctly calling upon us to do so.
It was upon this account that, according to the Stoics, it might be the duty of a wise man to remove out of life though he was perfectly happy; while, on the contrary, it might be the duty of a weak man to remain in it, though he was necessarily miserable. If, in the situation of the wise man, there were more circumstances which were the natural objects of rejection than of choice, the whole situation became the object of rejection, and the rule which the gods had given him for the direction of his conduct, required that he should remove out of it as speedily as particular circumstances might render convenient. He was, however, perfectly happy even during the time that he might think proper to remain in it. He had placed his happiness, not in obtaining the objects of his choice, or in avoiding those of his rejection; but in always choosing and rejecting with exact propriety; not in the success, but in the fitness of his endeavours and exertions. If, in the situation of the weak man, on the contrary, there were more circumstances which were the natural objects of choice than of rejection; his whole situation became the proper object of choice, and it was his duty to remain in it. He was unhappy, however, from not knowing how to use those circumstances. Let his cards be ever so good, he did not know how to play them, and could enjoy no sort of real satisfaction, either in the progress, or in the event of the game, in whatever manner it might happen to turn out (Cicero De finibus, lib. 3. c. 13.).
The propriety, upon some occasions, of voluntary death, though it was, perhaps, more insisted upon by the Stoics, than by any other sect of ancient philosophers, was, however, a doctrine common to them all, even to the peaceable and indolent Epicureans. During the age in which flourished the founders of all the principal sects of ancient philosophy; during the Peloponnesian War and for many years after its conclusion, all the different republics of Greece were, at home, almost always distracted by the most furious factions; and abroad, involved in the most sanguinary wars, in which each fought, not merely for superiority or dominion, but either completely to extirpate all its enemies, or, what was not less cruel, to reduce them into the
