 But there is a natural mistake which, perhaps, I should briefly notice. Our inner worlds, I may be told, are divided from each other, but the outer world of experience is common to all; and it is by standing on this basis that we are able to communicate. Such a statement would be incorrect. My external sensations are no less private to myself than are my thoughts or my feelings. In either case my experience falls within my own circle, a circle closed on the outside; and, with all its elements alike, every sphere is opaque to the others which surround it. With regard to communicability, there is in fact not any difference of kind, but only of degree. In every case the communication must be made indirectly, and through the medium of our outsides. What is true is that, with certain elements, the ways of expression may be shorter and less mistakeable; and again the conditions, which secure a community of perception, are, with certain elements, more constant and more subject to our control. So much seems clear, but it is not true that our physical experiences have unity, in any sense which is inapplicable to the worlds we call internal. Nor again, even in practice, is it always more easy to communicate an outer than an inner experience. In brief, regarded as an existence which appears in a soul, the whole world for each is peculiar and private to that soul. But, if on the other hand, you are considering identity of content, and, on that basis, are transcending such particular existences, then there is at once, in principle, no difference between the inner and the outer. No experience can lie open to inspection from outside; no direct guarantee of identity is possible. Both our knowledge of sameness, and
