Makes the Freud/Jung correspondence accessible to a general readership at a time of renewed critical and historical reevaluation of the documentary roots of modern psychoanalysis.

'The substance of intellectual history at a turning point is in these letters. The impression is of two immensely ambitious, self-willed, often inspired men, who had set themselves apart as innovators, roped together in a long climb into a new world.' -The Observer

"The relationship between Sigmund Freud and C. G. Jung had its bright beginning in 1906 and came to its embittered end in 1913. Its disastrous course was charted by the many letters the two men wrote each other.... In 1970 the Freud and Jung families made the enlightened decision that this correspondence was to be edited as a unit and published.... In no way does it disappoint the large expectation it has naturally aroused. Both as it bears upon the personal lives of the men between whom the letters passed and upon the intellectual history of our epoch, it is a document of inestimable importance."---Lionel Trilling, The New York Times Book Review
