Pythagoras made two co-ordinations of things, one as follows :

Finite - Straight Odd - Light One - Square Right - Rest Male - Good.

But the other is:

Infinite - Crooked Even - Darkness Multitude - Oblong Left - Motion Female - Evil.

The Pythagoreans, however, by placing the one in the co-ordination of things good, indicated its perfective and preserving nature. For every thing is perfected in this, and is benefited and preserved by abiding in unity, since it is thus undissipated and undivided. But when it loses its oneness, it also loses its being.
