Excerpt from Mind, Vol. 3: A Quarterly Review of Psychology and Philosophy Impartial readers of recent English discussions of the space question will be ready to admit that there is still ample room for more than one theory of the subject. Some years ago it was commonly thought that, thanks to the arguments of the Berkeleyans aided by the experiments of Wheatstone and others the derivative nature of visual space was amply demonstrated. Yet the skilful rehabilitation of the opposite doctrine by Bailey proved, as J. S. Mill allowed, how great the difficulties are which still beset the problem. More recently the ingenious arguments of what may perhaps be called the Dublin school, including Messrs. Abbot, Monck, and Mahaffy, have shown that the theory of visual space is even now far from being finally determined.
