Explorations in Personality, published by Oxford University Press in 1938, set forth a provocative and comprehensive agenda for the scientific study of human personality. Blending no-nonsense empiricism with the humanistic desire to understand the whole person, the book is as relevant to students of personality psychology today as it was to its many readers 70 years ago. Assisted by such eminent colleagues as Erik Erikson and Robert White, Henry Murray set forth a full theory of human personality, illustrated a bevy of creative methods for personality assessment, and presented the results of a landmark study of fifty Harvard men. Explorations in Personality is one of the great classics in 20th century psychology. This reissue, enhanced by Dan McAdams' foreword, which provides a contemporary evaluation of Murray's achievement, will be of great interest to students and researchers in personality psychology and to many other behavioral scientists, scholars, and general readers who wish to understand the psychology of the whole person.
