Jung’s PSYCHOLOGICAL TYPES appeared in 1921 to widespread
acclaim and received many laudatory reviews.1 In a two- page
spread in the New York Times Book Review, Mark Isham
concluded: “This volume is drastically serious, positive, didactic,
classic, and yet more than stimulating. It is energizing, liberating
and recreative. The author shows an amazingly sympathetic
knowledge of the introvert of the thinking type, and
hardly less for the other types. . . . Jung has revealed the inner
kingdom of the soul marvelously well and has made the signal
discovery of the value of phantasy. His book has a manifold
reach and grasp, and many reviews with quite different subject
matter could be written about it” (1923). Psychological
Types has been one of Jung’s most infl uential and enduring
works, leaving an indelible mark on psychology, psychotherapy,
personality testing, anthropology, popular culture,
and even language. It was Jung’s fi rst major publication in
nearly a decade since his 1911– 12 book on Transformations and
Symbols of the Libido.
