This article consists of three parts. The first deals with the conflict between those who boast the achievements of Science, and those who insist that scientific methods are inapplicable in certain departments of reality. Philosophy alone, it is claimed, can put an end to the strife. In the second part an effort is made to state the mutual relations of Science and Philosophy; also, to show the attitude of each to reality. "Science concerns itself with the mutual relation of objects, considered independently of their relation (1) to a sentient and thinking subject, (2) to the whole of existence. Science undertakes to determine the objective relations of phenomena, while it eliminates as much as possible the consciousness for which they exist and through which they are known. Such a point of view is partial and abstract, since it does not embrace the whole of reality. After abstracting the thinking subject, pure sciences abstract still further all objects other than the one which is to be considered. Philosophy corrects the abstraction which has been made of the thinking subject, reestablishes the unity of nature and of thought." The third pant treats of the place of 'faith' or ' belief ' in practical life. It contains, also, a discussion of the relations of science, religion, and philosophy.

Representative space in its triple form—visual, tactile, and motor—is essentially different from geometrical space. The latter is continuous, infinite, tri-dimensional, and homogeneous, that is, all its points are of identical value in it. Pure visual space has only two dimensions, is limited, not continuous, not homogeneous. Tactile space is still more complex and further removed from geometrical space. Motor space is not homogeneous, and has potentially as many dimensions as there are nerve fibres reporting external objects. This number is actually reduced, by neglecting certain of these reports, finding by experience that they agree, sufficiently for practical purposes, with certain others. But this reduction is not an
