“The word control raises a familiar issue. What right has a therapist to manipulate the conditions of which a person’s behavior is a function? The question is more often asked about the use of punitive consequences by governments or positive reinforcers by business and industry. If it is not so often asked of psychotherapists, it is because they have not demonstrated any threatening power or because, like Carl Rogers, they insist that they are not exercising control at all.” (p. 79)
