Now, if words have any meaning at all, it must follow from the passages quoted above, that each cell in the human body is a person with an intelligent soul, of a low class, perhaps, but still differing from our own more complex soul in degree, and not in kind; and, like ourselves, being born, living, and dying. So that each single creature, whether man or beast, proves to be as a ray of white light, which, though single, is compounded of the red, blue, and yellow rays. It would appear, then, as though “we,” “our souls,” or “selves,” or “personalities,” or by whatever name we may prefer to be called, are but the _consensus_ and full flowing stream of countless sensations and impulses on the part of our tributary souls or “selves,” who probably know no more that we exist, and that they exist as part of us, than a microscopic water-flea knows the results of spectrum analysis, or than an agricultural labourer knows the working of the British constitution: and of whom we know no more, until some misconduct on our part, or some confusion of ideas on theirs, has driven them into insurrection, than we do of the habits and feelings of some class widely separated from our own. These component souls are of many and very different natures, living in territories which are to them vast continents, and rivers, and seas, but which are yet only the bodies of our other component souls; coral reefs and sponge-beds within us; the animal itself being a kind of mean proportional between its house and its soul, and none being able to say where house ends and animal begins, more than they can say where animal ends and soul begins. For our bones within us are but inside walls and buttresses, that is to say, houses constructed of lime and stone, as it were, by coral insects; and our houses without us are but outside bones, a kind of exterior skeleton or shell, so that we perish of cold if permanently and suddenly deprived of the coverings which warm us and cherish us, as the wing of a hen cherishes her chickens. If we consider the shells of many living creatures, we shall find it hard to say whether they are rather houses, or part of the animal itself, being, as they are, inseparable from the animal, without the destruction of its personality.
