One of the great dramatic events in the history of twentieth-century thought was the break of Carl Jung--the crown prince of the psychoanalytic movement--with his mentor and collaborator Sigmund Freud. After the "gladiatorial phase" of the debate between the Freudians and Jungians had passed, British psychoanalyst Edward Glover began serious consideration of the ideas of Jung. Glover's study was immediately recognized as the major Freudian statement on Jung's psychology and was even cited by later Jungians for its trenchant criticisms. This new edition of the unsurpassed classic will make it available for another generation of students, practitioners, and intellectual historians.
