Instead of congresses devoted to each special science, such as have met in connection with other expositions, one great congress has been planned to represent the total accomplishment and unity of science.

Professor Münsterberg in an article on the congress in The Journal of Philosophy says: "Almost every one of these European scholars has in his own field brought about a certain synthesis of widely separated elements of thought, and has devoted not the smallest part of his work to the fundamental conceptions and methods of his science. The addresses which they will deliver thus lie essentially in the line of their own best thought, and yet it is most probable that the greater part of these addresses would never have been written had not the outer occasion of our
