B.F. Skinner — "The only difference between rats and people is that rats learn from experience."

"Man is a machine in the sense that he is a complex system behaving in lawful ways, but the complexity is extraordinary."

"I am sometimes accused of having left something out of account in my analysis of human behavior, and I usually admit it. I have left out the mind."

"The ideal of behaviorism is to eliminate coercion: to apply controls by changing the environment in such a way as to reinforce the kind of behavior that benefits everyone."

"The future of man depends on the control of human behavior."

"The experimental analysis of behavior is a natural science, a branch of biology."
