It will appear much less so now. The conception of aphasia then classical, universally admitted, believed to be unshakeable, has been considerably shaken in the last few years, chiefly by reasons of an anatomical order, but partly also by reasons of the same kind as those which we then advanced. And the profound and original study of neuroses made by Professor Pierre Janet has led him, of late years, to explain all psychasthenic forms of disease by these same considerations of psychic 'tension' and of attention to reality which were then presumed to be metaphysical.

In truth, it was not altogether a mistake to call them by that name. Without denying to psychology, any more than to metaphysics, the right to make itself into an independent science, we believe that each of these two sciences should set problems to the other and can, in a measure, help it to solve
