B.F. Skinner — "The human organism is not a mere puppet, but a complex system that interacts wit…"

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

"No one asks how to motivate a baby. A baby naturally explores everything it can get at, unless restraining forces have already been at work. And what is true of the baby is true of the scientist."

"The technology of behavior is not a threat to freedom, but a means to achieve it."

"The consequences of behavior determine the behavior."

"The ideal of a body of knowledge to which all men can contribute and which all men can use has been the great motivating force of science."
