ABSTRACT
In order to put Foulkes’ comments into their context, Fairbairn’s paper is here briefly summarized. Fairbairn’s paper was not written for a psychoanalytic readership but for the British Journal of the Philosophy of Science. The Editor of this journal also invited comments from Balint, Foulkes and Sutherland, and a reply from Fairbairn to these comments. Foulkes’ comments are included in full. Extracts from Fairbairn’s reply are also given.
