What I desire to consider with you to-night may fairly be described as a new situation in the philosophical world. And I may begin by saying that it is satisfactory that there should be a new situation. It is a testimony to the inexhaustibleness of reality, and, What is really the same thing, to the fecundity of the human mind. And in the next place, I shall attempt to shew that the nature of the new appearance constitutes a real advance. There is, indeed, always, I believe, a double interpretation possible in face of new attitudes of mind. The novelty may be satisfactory in itself, or it may be satisfactory because of its suggestions. I shall touch upon such a problem of inter pretation this evening.
