Carl Rogers is responsible for developing the humanistic school of psychotherapy, which places high emphasis on developing the therapeutic relationship through what came to be known as client-centred therapy. For Rogers, he instinctively thought that the client knew what was best for him and her, and the role of the therapist was therefore to use the three core conditions in order to create a strong therapeutic relationship that would allow the therapist to guide the client on his or her own journey as they voyaged towards wholeness. Note what Rogers himself said about the role of the client in the following quote:
It is the client who knows what hurts, what directions to go, what problems are crucial, what experiences have been deeply buried.
The role of the therapist therefore, who obviously does not know this information, is to primarily listen and create a trustful environment that will enable the client to effectively heal themselves. The three core conditions that Rogers believed were key for this therapeutic relationship to exist are: empathy, unconditional positive regard and congruence. Each, Rogers believed, are key to successful therapy, because only with those three core conditions would a client feel that they were in a safe, trusted place where they could talk about what is really going on within them.
