"Among the psychologists (and psychologist-philosophers) the old defenders of the dual nature of man—William James, Wiliam McDougall, Henri Bergson, and Hans Driesch—are now gone from the scene, and there are no comparable successors. The soul theory of personality has passed into psychological history.
      "Yet oddly enough, no one even claims to have proved that the mind is physical." etc.

(J.B. Rhine, The Reach of the Mind, New York, William Sloane, 1947, p. 7).

Comment There had been in the meanwhile numerous claims made that 'mind' is physical, invariably assuring the reader that the subject-matter "cannot be understood". Scores or hundreds of pages then follow on the 'subject' which "cannot be understood".

However, 'the soul theory of personality' has not passed into psychological history. Personally, I find some such propositions understandable, the difficulties being almost exclusively verbal. (WPT. Sept 07).
