As a digression of some importance, I venture to say that claims of thoughtless and pertinacious people upon the charitable and eminent, even here, are often excessive: it is to be hoped that such claims become less troublesome and less effective hereafter; but it is a hope without much foundation. Remonstrances are useless, however, for only the more thoughtful and those most deserving of help are likely to attend to remonstrances. Nevertheless--useless or not--it behoves one to make them. We are indeed taught that in exceptional cases there may ultimately supervene such an extraordinary elevation of soul that no trouble is too great, and no appeal is unheard. But still, even in the Loftiest case of all, the episode of having passed through a human body contributes to the power of sympathising with and aiding ordinary humanity. CHAPTER VIII MIND AND BRAIN "For nothing is that errs from law."--TENNYSON It is sometimes thought that memory is located in the brain; and undoubtedly there must be some physiological process at work in the brain when any incident of memory is recalled and either uttered or written. But it does not at all follow that memory itself is located in the brain; though there must be some easier channel, or some already prepared path, which enables an idea to be translated from the general mental reservoir into consciousness, with clarity and power sufficient to stimulate the necessary nerves and muscles into a condition adequate for reproduction. Sometimes in order to remember a thing, one writes it in a note-book; and the memory may be said to be in the note-book about as accurately as it may be said to be in the brain. A physical process has put it in the note-book; there is a physical configuration persisting there; and when a sort of reverse physical process is repeated, it can be got back into consciousness by simply what we call 'looking' at the book and reading. But surely the real memory is in the _mind_ all the time, and the deposit in the note-book is a mere detent for calling it out or for making it easy of recovery. In order to communicate any information we must focus attention on it; and whether we focus attention on a part of the brain or on a page of a note-book matters very little; the attention itself is a mental process, not a physiological one, though it has a physiological concomitant. This is an important matter, the keystone in fact of our problem about the connexion between mind and matter, and I propose to amplify its treatment further; for this is an unavoidably controversial portion of the book.
