Of course, behaviorism works. So does torture. Give me a no-nonsense, down-to-earth behaviorist, a few drugs, and simple electrical appliances, and in six months I will have him reciting the Athanasian Creed in public.
Suppose that humans happen to be so constructed that they desire the opportunity for freely undertaken productive work. Suppose that they want to be free from the meddling of technocrats and commissars, bankers and tycoons, mad bombers who engage in psychological tests of will with peasants defending their homes, behavioral scientists who can't tell a pigeon from a poet, or anyone else who tries to wish freedom and dignity out of existence or beat them into oblivion.
What is the appropriate behavior for a man or a woman in the midst of this world, where each person is clinging to his piece of debris? What's the proper salutation between people as they pass each other in this flood?
Physics does not change the nature of the world it studies, and no science of behavior can change the essential nature of man, even though both sciences yield technologies with a vast power to manipulate the subject matters.
When man learns to understand and control his own behavior as well as he is learning to understand and control the behavior of crop plants and domestic animals, he may be justified in believing that he has become civilized.
I place a high moral value on the way people behave. I find it repellent to have a lot, and to behave with anything other than courtesy in the old sense of the word -- politeness of the heart, a gentleness of the spirit.
