THE LOGIC OF STOICISM.--Stoicism existed as a germ in the Cynic philosophy (and also in Socrates) as did Epicureanism in Aristippus. Zeno was the pupil of Crates. In extreme youth he opened a school at Athens in the Poecile. The Poecile was a portico; portico in Greek is stoa, hence the name of Stoic. Zeno taught for about thirty years; then, on the approach of age, he died by his own hand. Zeno thought, as did Epicurus and Socrates, that philosophy should only be the science of life and that the science of life lay in wisdom.
