Some methodological reflections on the difficulties of psychoanalytic research.

AUTHOR’S NOTE: Revised and expanded version of a paper read at a joint session of the Division of Experimental Psychology and the Society for Projective Techniques, seventy-fourth annual convention of the American Psychological Association at New York City, September 6, 1966 (see American Psychologist, 21 (1966), 701). The present version is appearing as part of a symposium in Psychological Issues and is printed here by the kind permission of Dr. George S. Klein, editor. This work was largely done during my summer appointments as professor in the Minnesota Center for Philosophy of Science, under support from the Carnegie Corporation of New York. I should also like to express my indebtedness to colleagues Herbert Feigl, Carl P. Malmquist, and Grover Maxwell for the stimulation, criticism, and clarification provided, as always, at Center discussions.
