The vitalizing effect, spoken of somewhere by Graham Wallas, which one University “subject” may have upon another if the traditional division of compartments can be broken down, has nowhere been better illustrated of late years than by the life brought into the English school at Cambridge through the teaching of Dr. I. A. Richards, who came out of the school of Mental and Moral Science. Not only his students, but contemporaries and elders as remote as myself, are grateful for the stimulus he has given; and not least grateful for the necessity imposed upon them of making clearer to their own minds the grounds upon which at various points they find themselves in disagreement with him, and the positive suggestions which they would wish to substitute for his. Their final task must be to try to make those suggestions in some language which both sides may agree to use; barring out, therefore, a good many terms which Dr. Richards regards as standing for “evident fictions”—“fictions such as universals, essences, concepts, causes.”
