It is much more certain that the artist can help the philosopher than that the philosopher can help the artist. The purpose of this paper is to indicate the kind of questions about art which the philosopher asks, in order that those whose concern is with art, artists themselves in the first instance, and critics of art, may judge if these questions are interesting to them, and if so may co-operate with the philosophers in seeking to answer them. Now that the sciences and the other occupations of man become so sharply separated from each other, philosophy has come to have a peculiar position. It deals with the questions which are left over from the sciences, and this gives it a specific and important office to perform.
