…My long experience as a therapist convinces me that significant learning is facilitated in psychotherapy, and occurs in that relationship. By significant learning I mean learning which is more than an accumulation of facts. It is learning which makes a difference — in the individual’s behavior, in the course of action he chooses in the future, in his attitudes and in his personality. It is a pervasive learning which is not just an accretion of knowledge, but which interpenetrates with every portion of his existence.
Carl Rogers, from Chapter 14 of “On Becoming a Person”
