Having proved, to his satisfaction, that the nature of things is unknowable, Pyrrho proceeds to deal with the two remaining heads of the philosophic problem. To the question what should be our relation to a universe which we cannot reach, the answer is, naturally, one of total indifference. And the advantage to be derived from this attitude is, he tells us, that we shall secure the complete imperturbability wherein true happiness consists. The sceptical philosophy does not agree with Stilpo in denying the reality of actual and immediate annoyances, for it denies nothing; but it professes to dispel that very large amount of unhappiness which arises from the pursuit of fancied goods and the expectation of future calamities. In respect to the latter, what Pyrrho sought was to arrive by the exercise of reasoning at the tranquillity which unreasoning animals naturally enjoy. Thus, we are told that, when out at sea in a storm, he called the attention of the terrified passengers to a little pig which was quietly feeding in spite of the danger, and taught them that the wise man should attain to a similar kind of composure. Various other anecdotes of more or less doubtful authenticity are related, showing that the philosopher could generally, though not always, act up to his own ideal of indifference. He lived with his sister, who was a midwife by profession, and patiently submitted to the household drudgery which she unsparingly imposed on him. Once, however, she succeeded in goading him into a passion; and on being rather inopportunely reminded of his professed principles by a bystander, the sceptic tartly replied that a wretched woman like that was no fit subject for a display of philosophical indifference. On another occasion, when taunted for losing his self-possession at the attack of a furious dog, he observed, with truth, that, after all, philosophers are human beings.[228]
