I need not, I think, go any further into detail of new methods in each Science. You remember what I said at the beginning about the Cell studying the Body of which it formed a part. We may imagine, if we like, three stages in this process. In the first stage the Cell regards the other cells and the Body simply from the point of view of how they affect _it_, and its comfort and safety. This might be taken to correspond to the Old-time Science. In the second stage the Cell, with its tiny experience of the other cells and the small part of the body in which it is placed, becomes highly intellectual, and professes to lay down the laws of the structure of the body generally. This corresponds to the attitude of Modern Science. In the third stage the Cell, growing and evolving, and coming daily into closer sympathetic relationship with all parts of the body, begins to find its true relation to the other cells, not to use _them_, but to fulfil its part in the whole. Gradually drawing all the threads together and coming more and more, so to say, into a central position, it at last in its little brain spontaneously and inevitably reflects the whole, and becomes the mirror of it. This would answer to what we have called a really rational and humane Science. Man has to find and to _feel_ his true relation to other creatures and to the whole of which he is a part, and has to use his brain to further this. Science _is_, as we all know, the search for Unity. That is its ideal. It unites innumerable phenomena under one law; and then it unites many laws under one higher; always seeking for the ultimate complete integration. But (is it not obvious?) Man cannot find that unity _of_ the Whole until he feels his unity _with_ the Whole. To found a Science of one-ness on the murderous Warfare and insane Competition of men with each other, and on the Slaughter and Vivisection of animals--the search for unity on the practice of disunity--is an absurdity, which can only in the long run reveal itself as such. I do not know whether it seems obvious to you, but it does to me, that Man will never find in theory the unity of outer Nature till he reaches in practice the unity of his own. When he has learnt to harmonise in himself all his powers, bodily and mental, his desires, faculties, needs, and bring them into perfect co-operation--when he has found the true hierarchy of himself--then somehow I think that Nature round him will reflect this order, and range itself in clear and intelligible harmony about him. But I can say no more. I have dragged you by the neck, as it were, through a recondite and difficult subject; and even so I do not feel that I have by any means done justice to it. But it is possible, perhaps, that I have cast the germ of an idea among you, which, if you think over it at leisure, may develop into something of value. FOOTNOTES:
