For man did not appear on earth until the earth itself, together with all its biological forms, had evolved to a certain degree of balance and complexity. At this point of evolution the earth "implied" man, just as the existence of man implies that sort of a planet at that stage of evolution. The balance of nature, the "harmony of contained conflicts," in which man thrives is a network of mutually interdependent organisms of the most astounding subtlety and complexity. Teilhard de Chardin has called it the "biosphere," the film of living organisms which covers the original "geosphere," the mineral planet. Lack of knowledge about the evolution of the organic from the

"inorganic," coupled with misleading myths about life coming "into"

this world from somewhere "outside," has made it difficult for us to see that the biosphere arises, or goeswith, a certain degree of geological and astronomical evolution. But, as Douglas E. Harding has pointed out, we tend to think of this planet as a life-infested rock, which is as absurd as thinking of the human body as a cell-infested skeleton. Surely all forms of life, including man, must be understood as "symptoms" of the earth, the solar system, and the galaxy—in which case we cannot escape the conclusion that the galaxy is intelligent.

If I first see a tree in the winter, I might assume that it is not a fruit-tree. But when I return in the summer to find it covered with plums, I must exclaim, "Excuse me! You were a fruit-tree after all." Imagine, then, that a billion years ago some beings from another part of the galaxy made a tour through the solar system in their flying saucer and found no life. They would dismiss it as "Just a bunch of old rocks!" But if they returned today, they would have to apologize: "Well—you were peopling rocks after all!" You may, of course, argue that there is no analogy between the two situations. The fruit-tree was at one time a seed inside a plum, but the earth—much less the solar system or the galaxy—was never a seed inside a person. But, oddly enough, you would be wrong.

I have tried to explain that the relation between an organism and its environment is mutual, that neither one is the "cause" or determinant of the other since the arrangement between them is polar. If, then, it makes sense to explain the organism and its behavior in terms of the environment; it will also make sense to explain the environment in terms of the organism. (Thus far I have kept this up my sleeve so as not to confuse the first aspect of the picture.) For there is a very real, physical sense in which man, and every other organism, creates his own environment.

Our whole knowledge of the world is, in one sense, self-knowledge.

For knowing is a translation of external events into bodily processes, and especially into states of the nervous system and the brain: we know the world in terms of the body, and in accordance with its structure.

Surgical alterations of the nervous system, or, in all probability, sense-organs of a different structure than ours, give different types of perception—just as the microscope and telescope change the vision of the naked eye. Bees and other insects have, for example, polaroid eyes which enable them to tell the position of the sun by observing any patch of blue sky. In other words, because of the different structure of their eyes, the sky that they see is not the sky that we see. Bats and homing pigeons have sensory equipment analogous to radar, and in this respect see more "reality" than we do without our special instruments.

From the viewpoint of your eyes your own head seems to be an invisible blank, neither dark nor light, standing immediately behind the nearest thing you can see. But in fact the whole field of vision "out there in front" is a sensation in the lower back of your head, where the optical centers of the brain are located. What you see out there is, immediately, how the inside of your head "looks" or "feels." So, too, everything that you hear, touch, taste, and smell is some kind of vibration interacting with your brain, which
