Zeno first came under the influence of the Cynics when he arrived in Athens around 313 BCE. He later founded the philosophical school of Stoics (from stoa, doorway or porch, a point of congregation) around the year 308 BCE. He taught the calm and rational acceptance of all occurences as manifestations of the gods' will. He taught a particularly stringent ethics: one either lives up to the standard of the Stoic sage, and is therefore good, or one entirely lacks virtue.
