It takes a lot to overturn the accepted view of reality, but it doesn't take a lot to begin. The accepted view of reality holds that human beings exist in the context of a vast physical universe "out there." Only an extreme mystic would doubt this description, but all of us should. Sir John Eccles, a famous British neurologist and Nobel laureate, declared, "I want you to realize that there exists no color in the natural world, and no sound – nothing of this kind; no textures, no patterns, no beauty, no scent." What Eccles means is that all the qualities of Nature, from the luxurious scent of a rose to the sting of a wasp and the taste of honey, are produced by human beings. Erwin Schrödinger, one of the main founders of quantum mechanics, said essentially the same thing when he declared that photons, quanta of light, have no color, such properties arise in the biology of perception.
