“Quality is the response of an organism to its environment’ [he used this example because his chief questioners seemed to see things in terms of stimulus-response behavior theory]. An amoeba, placed on a plate of water with a drip of dilute sulfuric acid placed nearby, will pull away from the acid (I think). If it could speak the amoeba, without knowing anything about sulfuric acid, could say, ‘This environment has poor quality.’ If it had a nervous system it would act in a much more complex way to overcome the poor quality of the environment. It would seek analogues, that is, images and symbols from its previous experience, to define the unpleasant nature of its new environment and thus ‘understand’ it. “In our highly complex organic state we advanced organisms respond to our environment with an invention of many marvelous analogues. We invent earth and heavens, trees, stones and oceans, gods, music, arts, language, philosophy, engineering, civilization and science. We call these analogues reality. And they are reality. We mesmerize our children in the name of truth into knowing that they are reality. We throw anyone who does not accept these analogues into an insane asylum. But that which causes us to invent the analogues is Quality. Quality is the continuing stimulus which our environment puts upon us to create the world in which we live. All of it. Every last bit of it. “Now, to take that which has caused us to create the world, and include it within the world we have created, is clearly impossible. That is why Quality cannot be defined. If we do define it we are defining something less than Quality itself.” I remember this fragment more vividly than any of the others, possibly because it is the most important of all. When he wrote it he felt momentary fright and was about to strike out the words “All of it.”
