It is very illustrative of the unguarded points and contradictions of Stoicism, that contentment and apathy were not to permit grief even for the loss of friends. Seneca, on one occasion, admits that he was betrayed by human weakness on this point. On strict Stoical principles, we ought to treat the afflictions and the death of others with the same frigid indifference as our own; for why should a man feel for a second person _more_ than he ought to feel for himself, as a mere unit in the infinitude of the Universe? This is the contradiction inseparable from any system that begins by abjuring pleasure, and relief or protection from pain, as the ends of life. Even granting that we regard pleasure and relief from pain as of no importance in our own case, yet if we apply the same measure to others we are bereft of all motives to benevolence; and virtue, instead of being set on a loftier pinnacle, is left without any foundation. EPICURUS. [311--270 B.C.] Epicurus was born 341 B.C. in the island of Samos. At the age of eighteen, he repaired to Athens, where he is supposed to have enjoyed the teaching of Xenocrates or Theophrastus. In 306 B.C., he opened a school in a garden in Athens, whence his followers have sometimes been called the 'philosophers of the garden.' His life was simple, chaste, and temperate. Of the 300 works he is said to have written, nothing has come down to us except three letters, giving a summary of his views for the use of his friends, and a number of detached sayings, preserved by Diogenes Laertius and others. Moreover, some fragments of his work on Nature have been found at Herculaneum. The additional sources of our knowledge of Epicurus are the works of his opponents, Cicero, Seneca, Plutarch, and of his follower Lucretius. Our information from Epicurean writers respecting the doctrines of their sect is much less copious than what we possess from Stoic writers in regard to Stoic opinions. We have no Epicurean writer on Philosophy except Inicretius; whereas respecting the Stoical creed under the Roman Empire, the important writings of Seneca, Epictetus, and Marcus Antoninus, afford most valuable evidence.
