"When human life lay
groveling in all men's sight, crushed to the earth under the dead
weight of superstition...a man of Greece was first to raise mortal
eyes in defiance, first to stand erect and brave the challenge...He
ventured far out beyond the flaming ramparts of the world and voyaged
in mind throughout infinity." |
"Aristotle maintained that women have fewer teeth than men; although he
was twice married,
it never occurred to him to verify this statement by examining his wives' mouths."
--- Bertrand Russell
Copernicus' Heliocentric Model
