The simplest and most satisfactory view is that thought is simply behavior - verbal or nonverbal, covert or overt. It is not some mysterious process responsible for behavior but the very behavior itself in all the complexity of its controlling relations.

Problem-solving typically involves the construction of discriminative stimuli

We have seen that in certain respects operant reinforcement resembles the natural selection of evolutionary theory. Just as genetic characteristics which arise as mutations are selected or discarded by their consequences, so novel forms of behavior are selected or discarded through reinforcement.

Somehow people get the idea I think we should be given gumdrops whenever we do anything of value.

A person's genetic endowment, a product of the evolution of the species, is said to explain part of the workings of his mind and his personal history the rest.

The problem of far greater importance remains to be solved. Rather than build a world in which we shall all live well, we must stop building one in which it will be impossible to live at all.

Do not intervene between a person and the consequences of their own behavior.
