Psychologische Typen by JUNG, C[arl] G[ustav] - 1921

Zurich: Rascher & Cie, 1921. FIRST EDITION. Original printed gray wrappers; an excellent uncut copy. First edition of Jung's most important work. "His list of psychological types is one of the most ambitious that has been proposed . . . The psychological types, in which he expounds and illustrates this doctrine, is a fascinating work, and very high claims have been made for it, as when Baynes, its English translator, says 'that for practical psychologists it must assuredly be regarded as the foundation of the science, for in no other work do we find basic psychological principles whose validity is commensurate with the undeniable facts of man's historic development and the realities of individual experiences. Few psychologists would be prepared to dispute the truth of this statement. . . ." (Flugel & West, One Hundred Years of Psychology, pp. 252-54).
