In taking a glance at what they have to offer us, I shall not go far afield, and shall exercise a brevity compatible with the purpose of mere illustration. To the moralists of ancient Greece, and, to a lesser degree, to those of the Roman Empire, to the Christian teachers who succeeded to their heritage in the centuries which followed, and to the more or less independent thinkers who made their appearance after the Reformation, we can trace our ethical pedigree. For our purpose we need seek no wider field. Here we may find sufficiently notable contrasts of opinion to disturb the dogmatic slumber of even an inert mind. The most cursory glance makes us inclined to accept with some reserve Stephen's claim that "the difference between different systems is chiefly in the details and special application of generally admitted principles." 8. EPICUREAN AND STOIC.--Thus, Aristippus of Cyrene advised men to grasp the pleasure of the moment rather than to await the more uncertain pleasure of the future; but he also counselled, for prudential reasons, the avoidance of a conflict with the laws. Such advice takes cognizance of the self-love of the individual, and is not self-love reasonable? Nevertheless, such advice might be given by a discouraged criminal of a reflective turn of mind, on his release from prison, to a comrade not yet chastened by incarceration. Epicurus praises temperance and fortitude, but only as measures of prudence. He praises justice, but only in so far as it enables us to escape harm, and frees us from that dread of discovery that haunts the steps of the evil-doer. His more specific maxims, do not fall in love with a woman, become the father of a family, or, generally, go into politics, smack strongly of the rule of life recommended to Feuillet's hero, Monsieur de Camors, by his worldly-wise and cynical father. Contrast with these men the Stoics, whose rule of life was to follow Nature, and to eschew the pursuit of pleasure. Man's nature, said Epictetus, is social; wrongdoing is antisocial; affection is natural. [Footnote: _Discourses_, Book I, chapter xxiii--a clever answer to Epicurus.] Said Marcus Aurelius, it is characteristic of the rational soul for a man to love his neighbor. The cautious bachelor imbued with Epicurean principles would find strange and disconcerting the Stoic position touching citizenship: "My nature is rational and social; and my city and country, so far as I am Antoninus, is Rome, but so far as I am a man, it is the world. The things then which are useful to these cities are alone useful to me." [Footnote: _Thoughts_, Book VI, 44; translated by GEORGE LONG.]
