(fl. late 4th and early 3d cent. bc), Greek philosopher,
founder of
STOICISM, (q.v.). He
was born in Citium, Cyprus. Little is known of his early life except
that his contemporaries referred to him as a Phoenician. He was
a student of the 4th century bc Cynic philosopher Crates
of Thebes (365?–285 bc) and of the Platonist Xenocrates.
About 300 bc, Zeno founded his own school of philosophy,
known as Stoicism. The name of the school was derived from Stoa
Poikilf (“painted porch”),
the name given to the public portico where the master taught his
disciples. Moral obligation, self-control, and living in harmony
with nature were some of the principles of practical ethics with
which Zeno was chiefly concerned. He taught in Athens for more than
50 years and was publicly honored for his upright manner of living.
It is said, however, that he refused the offer of Athenian citizenship
out of loyalty to his native Cyprus. Zeno left no written accounts
of his teachings, but they were transmitted by his many disciples.
