experience and explain the phenomena of the world on a broader field. Mind is still regarded as the exclusive source of change, of thoughtful relations, of order instituted for an end. The laws that are in matter act with no more power of redirection or self-modification than belongs to the stones set in a building. They seem simply to preserve a fixed relation to a constructive service that has been put upon them by mind.

Mind also offers in its potentiality an available infinite. Infinite matter would be a plenum and admit no change, would exclude all modification, creation, evolution. All that empiricism charges on the notion of the infinite we admit as applied to matter. But mind may remain an unmeasured potentiality from which the finite may flow in perpetual expression.

Thus between the two terms, mind and matter, mind alone offers the spontaneous, creative, combining power which permits it to furnish an ultimate explanation to the Universe; mind alone can abide in that unwearied productiveness which offers a final term to human thought. No matter with what material terms we start, we reach no beginning. The whole problem is still in them entire and untouched at every stage. We ask without answer for the origin of things. A change of forms, but no change of forces is possible. All movement backward and forward expires by the slow retardation of weariness with no suggestion of any bounds. All thought thus becomes at length the unsolaced travel of a tread-mill, in which work is
