To begin with, specialism makes vision, the mind's vision as well as the sensuous vision, dim or distorted. It may even be said to induce a species of blindness or, as virtually the same thing, to create in consciousness curious fancies, strange perversions of reality, seen not with the natural eye at all, but with the imagination, always so ingenious and so original, and one might almost add so hypnotic, in its power of suggestion over the senses. In ways and for reasons neither unknown nor unappreciated by most men, specialism even closes one's eyes and makes one dream. It makes the specialist among physicians see his special ailment in every disorder, and every disorder in his special ailment, and this so truly that merely to consult him may be to fall his victim. True, he may never be, perhaps can never be, wholly wrong, and his transgressions, conscious or unconscious, have often helped discovery, but nevertheless his situation, not to say that of his patient, is full of humour, and always among other troubles he is under the error of partiality or one-sidedness. And in science generally the specialist always does and always must dream. His dreams may be waking dreams, but he is always transgressing his own proper bounds without ever [p.088] clearly comprehending that he has transgressed. Nor, be it admitted, can this necessity of dreaming be a wholly unmixed evil to science. However unfavourably it may reflect on the final, literal validity of any special science, it only shows nature, or reality, preserving her unity against the attempted violence of specialism. It shows that in spite of the specialist being all eyes for his own peculiar object, the mind that is within him and that is above all else--such, apparently, is the nature of mind--responsible not exclusively to the special and sensuous, but to the all-inclusive and essential, and is therefore bound to conserve for experience the interests of an indivisible universe in every particular thing, leads him, devotee that he is, patiently repeating his sacred syllable, into most wonderful visions. For the sake of inclusiveness and reality his mind projects his would-be special consciousness into regions of strange subtlety and marvellous logical construction; as Oriental priest or Occidental scientist he is a specialist, yet not without a mind, or a real, ever-present world, which refuses to be special, and as he dreams he comes to see, yet knows not that he sees, the whole universe. A seeing blindness, then, is this specialism; a monomania too, but, of course, conventional and respectable.
