It is a fascinating and provocative thought that a body of water deserves to be considered as an organism in its own right.

I live and work alone and travel light, relying largely on my memory and making a point of letting # intuition guide my way.

If the brain were so simple we could understand it, we would be so simple we couldn't.

Before sight and sound hijacked our attention, we shared with all life a sort of common sense, a chemical sense that depended on direct contact with matter in the water or the air.

If you simply walk on the beach as we are doing, you have no special color. But if you travel with a purpose, it is different. When you go somewhere important or you return home from a long journey, you build a shape around you and it reaches out ahead to touch your destination.

The limits of sensory evolution in fish are defined very largely by their habitat. Water is physically supportive, carries some kinds of odour well, and is kind to sound - letting it travel several times faster than air will allow, but it inhibits other more personal kinds of communication.
