When we say that a man controls himself, we must specify who is controlling whom.

Unable to understand how or why the person we see behaves as he does, we attribute his behavior to a person we cannot see, whose behavior we cannot explain either but about whom we are not inclined to ask questions.

A child who has been severely punished for sex play is not necessarily less inclined to continue; and a man who has been imprisoned for violent assault is not necessarily less inclined toward violence.

A failure is not always a mistake, it may simply be the best one can do under the circumstances. The real mistake is to stop trying.

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... behaviors have different 'meanings' is only another way of saying that they are controlled by different variables.

Chaos breeds geniuses. It offers a man something to be a genius about.
