William McDougall Quotes
Hypnotism (1945) by Axel Wayne Bacon. In the Preface to the 1960 edition, Nelson-Hall Co., Publishers
William McDougall FRS was an early 20th century psychologist who spent the first part of his career in the United Kingdom and the latter part in the United States. He wrote a number of highly influential textbooks, and was particularly important in the development of the theory of instinct and of social psychology in the English-speaking world. He was an opponent of behaviourism and stands somewhat outside the mainstream of the development of Anglo-American psychological thought in the first half of the 20th century; but his work was very well-known and respected among lay people.
