Abstract

The concept of evolution is of fundamental importance to any general scheme of thought: and one of the ways in which its importance is greatest is in defining the place of mind within any such scheme. If bodies and their contained brains have evolved, why not the accompanying minds? Indeed, to-day the question can only be properly put the other way round: how can the minds not have evolved? Mental evolution can only have failed to occur if we deny to mind the principle of continuity, which is one of our axioms on the physical side: only, that is to say, if the world ceases to be rational
