If there be light, then there is darkness; if cold, heat; if height, depth; if solid, fluid; if hard, soft; if rough, smooth; if calm, tempest; if prosperity, adversity; if life, death.
PythagorasHe who knoweth not what he ought to know, is a brute beast among men; he that knoweth no more than he hath need of, is a man among brute beasts; and he that knoweth all that may be known, is as a God among men.
Pythagoras
