We have not yet seen what man can make of man.

It is a mistake to suppose that the whole issue is how to free man. The issue is to improve the way in which he is controlled.

Teachers must learn how to teach ... they need only to be taught more effective ways of teaching.

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.

I may say that the only differences I expect to see revealed between the behavior of the rat and man (aside from enormous differences of complexity) lie in the field of verbal behavior.

To say that a man is sinful because he sins is to give an operational definition of sin. To say that he sins because he is sinful is to trace his behavior to a supposed inner trait. But whether or not a person engages in the kind of behavior called sinful depends upon circumstances which are not mentioned in either question. The sin assigned as an inner possession (the sin a person "knows") is to be found in a history of reinforcement.
