Here in one volume are the seminal papers by Joseph Sandler, Alex Holder, and Christopher Dare on Freud's theories, which originated in the early seventies as a group of lectures by Sandler at the Institute of Psychiatry, University of London (Maudsley Hospital), and were subsequently revised and elaborated into a series of papers by Sandler, Holder, and Dare, published in the British Journal of Medical Psychology between 1970 and 1978. A final, twelfth paper, published in 1982, is also included along with material necessary for the completion of the work, which has been added by Joseph Sandler and Anna Ursula Dreher along with extensive notes and commentary referring to later developments in psychoanalysis.
