Sullivan pleads for psychiatric support of the W.H.O., the potentialities of which 'are the potentialities of the people who will provide its effective support, of the people who will contribute wise policy, and of the people who will administer this policy in the organization'. He deplores the relatively low numerical representation of psychiatrists at the first assembly of the W.H.O. and emphasizes anew the possibilities inherent in psychiatry's contribution to society. He warns against any conscious or unconscious attempt to impose the standards of our particular culture on societies quite different from our own. Little can or will be achieved, however, without active participation, and without some sense of world citizenship.
