And what passes for wisdom is not;
unwise are those who aspire, who outrange the limits of man.
Briefly, we live. Briefly,
then die. Wherefore, I say,
he who hunts a glory, he who tracks
some boundless superhuman dream,
may lose his harvest here and now
and garner death. Such men are mad,
their counsels evil.
Euripides, Bacchae, lines 395-400
