ATHEISM:
originally used in Greece of all those who, whether they believed in a
GOD or not, disbelieved in the official GODS of the State: SOCRATES was the classic
instance. In the Roman Empire the term was applied to CHRISTIANS but sometimes Christians,
like POLYCARP, would turn the term against their persecutors. Until the expression
"AGNOSTICISM" came into general use in the nineteenth century, the term
"ATHEISM" was popularly used to describe those who thought the EXISTENCE of GOD
an unprovable thesis.
