Out of the great No-thing, which is the Void, arises that which is symbolically and mathematically the single point. It is the first appearance within space and time.
This point turns itself into the line, whose two ends oppose and complement each other. This is the cosmic symbol of universal polarity, called by the Chinese Yin-Yang, or masculine-feminine, positive and negative, projective and receptive, creation and disintegration.
The next phase of this dynamic active process is, still speaking symbolically, the development which spreads itself out into the entire Cosmos itself, like a fan, moving by itself as if by magic.
Out of their own thinking the Greeks developed somewhat similar mystical, metaphysical, and mathematical ideas whose geometry is based on the point, the line, the plane, and the solid.
