I imagine that I lived in the ancient time, and was a hunter of deers and a forager of berries. I saw the direction of streams, the movements of stars, the shapes of clouds in summers and winters, and the colours of trees in springs and autumns. The lawfulness of nature was apparent to me, although I could not decipher the details of its laws.

What language must I create to describe nature? What system must I invent, to organize observations and experiences?

Reading I-Ching, a sweeping vision of nature and humanity spreads before me.

I-Ching, also known as the Book of Change, is a system said to be originated by Fu Hsi (~2800BC). Using a binary notation to represent a set of 64 symbols, it is an elaborate system that interprets the processes of nature, and thereby the affairs of man.

The name "I Ching" implies three ideas: Simplicity, Change, and Invariability. Each entry in the book starts with a hexagram,

• 0-1
• 2-3
