The Absolute Relations of Time and Space


IN 1914 Dr. Robb published a work entitled “A Theory of Time and Space.” Bearing in mind the circumstances of that year, it is not surprising to find that the book did not attract a notice commensurate either with the intrinsic importance of the subject or with the novelty of the views propounded in it. The short work bearing the above title is introductory to the larger work, and contains a concise statement of the main results embodied in it. The treatment is very different from that of Einstein. In Einstein's theory the emphasis is laid exclusively on the idea of the “relativity” of experience. Dr. Robb, on the other hand, postulates as the basis of his theory an absolute relation—namely, the relation of “before and after.” Not only does this relation serve as a physical basis; it is also the foundation on which he builds a goodly structure—his purely geometrical theory of time, of which the theory of space forms a part.
