Rollo May (1909 – 1994)
American Existential Psychologist – an important influence on Humanistic Psychology, May was adamant to convey the message that the therapist working with a client must participate in the world of the client and with this basic motivation. May wrote that “the existential movement in psychiatry and psychology arose precisely out of a passion to be not less but more ‘empirical’ – from the Greek empeiria, meaning experiential.
