Pythagoras. ca.560-ca.480 BC. Greek philosopher and mathematician.

There is geometry in the humming of the strings. There is music in the spacing of the spheres.
Geometry is knowledge of the eternally existent.
 


Above the cloud with its shadow is the star with its light. Above all things reverence thyself.



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.



The oldest, shortest words - "yes' and "no" - are those which require the most thought.
