In truth, the Stoics, who taught that all virtue was conformity to nature, were, in this respect, eminently false to their own principle. Human nature, as revealed to us by reason, is a composite thing, a constitution of many parts differing in kind and dignity, a hierarchy in which many powers are intended to co-exist, but in different positions of ascendancy or subordination. To make the higher part of our nature our whole nature, is not to restore but to mutilate humanity, and this mutilation has never been attempted without producing grave evils. As philanthropists, the Stoics, through their passion for unity, were led to the extirpation of those emotions which nature intended as the chief springs of benevolence. As speculative philosophers, they were entangled by the same desire in a long train of pitiable paradoxes. Their famous doctrines that all virtues are equal, or, more correctly, are the same, that all vices are equal, that nothing is an evil which does not affect our will, and that pain and bereavement are, in consequence, no ills,(242) though partially explained away and frequently disregarded by the Roman Stoics, were yet sufficiently prominent to give their teaching something of an unnatural and affected appearance. Prizing only a single object, and developing only a single side of their nature, their minds became narrow and their views contracted. Thus, while the Epicureans, urging men to study nature in order to banish superstition, endeavoured to correct that ignorance of physical science which was one of the chief impediments to the progress of the ancient mind, the Stoics for the most part disdained a study which was other than the pursuit of virtue.(243) While the Epicurean poet painted in magnificent language the perpetual progress of mankind, the Stoic was essentially retrospective, and exhausted his strength in vain efforts to restore the simplicity of a by-gone age. While, too, the school of Zeno produced many of the best and greatest men who have ever lived, it must be acknowledged that its records exhibit a rather unusual number of examples of high professions falsified in action, and of men who, displaying in some forms the most undoubted and transcendent virtue, fell in others far below the average of mankind. The elder Cato, who, though not a philosopher, was a model of philosophers, was conspicuous for his inhumanity to his slaves.(244) Brutus was one of the most extortionate usurers of his time, and several citizens of Salamis died of starvation, imprisoned because they could not pay the sum he demanded.(245) No one eulogised more eloquently the austere simplicity of life which Stoicism advocated than Sallust, who in a corrupt age was notorious for his rapacity. Seneca himself was constitutionally a nervous and timid man, endeavouring, not always with success, to support himself by a sublime philosophy. He guided, under circumstances of extreme difficulty, the
