The individual does actually carry on a double existence: one designed to serve his own purposes and another as a link in a chain, in which he serves against, or at any rate without, any volition of his own.

Psychoanalysis remains influential within psychiatry and across the humanities. His analysis of his own and his patients dreams as wish-fulfilments provided him with models for the clinical analysis of symptom formation and the mechanisms of repression as well as for further elaboration of his theory of the unconscious as an agency disruptive of conscious states of mind. Auden wrote in a poem dedicated to him: "to us he is no more a person / now but a whole climate of opinion / under whom we conduct our different lives".
