THE NEW PSYCHOLOGY.--Not only physical and biological, but psychological science will contribute very largely to the reconstruction of view which is now taking place. Particular attention is due to those branches of psychology which deal experimentally with the subconscious, with instincts, with the phenomena of thought transference, psychotherapy, and of so-called "spiritualism." In none of these spheres can research yet be said to have proceeded far enough to justify the luxury of dogmatising over results. Considerable confusion of opinion may still exist, but it is now generally recognised that there is a wide sphere of research in psychical regions which is practically a _terra incognita_. And those most competent to judge of results seem to be most cautious in their statements. We are in the position of not knowing what a day may bring forth; and an expectant agnosticism with regard to many problems is perhaps the right attitude to adopt. The somewhat arrogant negations of the last generation are now out of place; they were never, in the strict sense, scientific, and they are now demodes. It is extremely difficult to imagine a return to the view which dismisses "mind" from the universe as being an obscure by-product of matter, or a comparatively insignificant "epiphenomenon" accompanying certain obscure chemical or mechanical processes. The old theories, gratifying in their simplicity, will no longer cover the facts. PSYCHICAL RESEARCH.--One particular branch of experimental psychology, which has attracted a large measure of public attention, calls for a few remarks. The attempt has been made to give experimental proof of the existence of "disembodied spirits," human or otherwise. The whole subject, exceptionally exposed as it is to the influence of prejudices of various kinds, requires to be treated with great caution, and it is inadvisable, in the present condition of the problem, to make dogmatic statements in any direction. What appears to be certain is that the occurrence is well established of various _phenomena_ which it is extremely difficult to explain in accordance with our present knowledge of matter, of space, or of mental action. The occurrence of such phenomena is no longer disputed; but it is over the _explanation_ of them that controversy is active. And it seems quite certain that the very least in the way of concessions that these new facts will force from conservative scientists is _a radical revision of current notions of the range of human mental action_. The mind is evidently capable of producing certain effects--even upon matter--which would have seemed incredible a short while ago.
