In keeping with the old principle of triangulation, you cannot establish the position of a particular object unless you observe it from two particula… - Alan Watts

Human desire tends to be insatiable. We are so anxious for pleasure that we can never get enough of it. We stimulate our sense organs until they become insensitive, so that if pleasure is to continue they must have stronger and stronger stimulants. In self-defense the body gets ill from the strain, but the brain wants to go on and on. The brain is in pursuit of happiness, and because the brain is much more concerned about the future than the present, it conceives happiness as the guarantee of an indefinitely long future of pleasures. Yet the brain also knows that it does not have an indefinitely long future, so that, to be happy, it must try to crowd all the pleasures of Paradise and eternity into the span of a few years.

[T]he problem of man and technics is almost always stated in the wrong way. It is said that humanity has evolved one-sidedly, growing in technical power without any comparable growth in moral integrity, or, as some would prefer to say, without comparable progress in education and rational thinking. Yet the problem is more basic. The root of the matter is the way in which we feel and conceive ourselves as human beings, our sensation of being alive, of individual existence and identity. We suffer from a hallucination, from a false and distorted sensation of our own existence as living organisms. Most of us have the sensation that “I myself” is a separate center of feeling and action, living inside and bounded by the physical body — a center which “confronts” an “external” world of people and things, making contact through the senses with a universe both alien and strange. Everyday figures of speech reflect this illusion. “I came into this world.” “You must face reality.” “The conquest of nature.”

This feeling of being lonely and very temporary visitors in the universe is in flat contradiction to everything known about man (and all other living organisms) in the sciences. We do not “come into” this world; we come out of it, as leaves from a tree. As the ocean “waves,” the universe “peoples.” Every individual is an expression of the whole realm of nature, a unique action of the total universe. This fact is rarely, if ever, experienced by most individuals. Even those who know it to be true in theory do not sense or feel it, but continue to be aware of themselves as isolated “egos” inside bags of skin.

Naturally, for a person who finds his identity in something other than his full organism is less than half a man. He is cut off from complete participation in nature. Instead of being a body, he 'has' a body. Instead of living and loving he 'has' instincts for survival and copulation.
