It certainly does not. Our universe contains nothing that can be represented by that figure. Indeed if anywhere such a self-sufficing organism did exist, we could never know it. For, by the hypothesis, it would be altogether adequate to itself and without relations beyond its own bounds. And if it were thus cut off from connection with everything except itself, it could not even affect our knowledge. It would be a closed universe within our universe, and be for us as good as zero. We must own, then, that we have no acquaintance with any such perfect organism, while the facts of life reveal conditions widely unlike those here represented. What these conditions are becomes apparent when we put significance into the letters hitherto employed. Let our diagram become a picture of the organic life of John. Then A might represent his physical life, B his business life, C his civil, D his domestic; and we should have asserted that each of these several functions in the life of John assists all the rest. His physical health favors his commercial and political success, while at the same time making him more valuable in the domestic circle. But home life, civic eminence, and business prosperity also tend to confirm his health. In short, every one of these factors in the life of John mutually affects and is affected by all the others. But when thus supplied with meaning, Figure 3 evidently fails to express all it should say. B is intended to exhibit the business life of John. But this is surely not lived alone. Though called a function of John, it is rather a function of the community, and he merely shares it. I had no right to confine to John himself that which plainly stretches beyond him. Let us correct the figure, then, by laying off another beside it to represent Peter, one of those who shares in the business experience of John. This common business life [Fig. 4] of theirs, B, we may say, enables Peter to gratify his own adventurous disposition, E; and this again stimulates his scientific tastes, F. But Peter's eminence in science commends him so to his townsmen that he comes to share again C, the civic life of John. Yet as before in the case of John, each of Peter's powers works forward, backward, and across, constructing in Peter an organic whole which still is interlocked with the life of John. Each, while having functions of his own, has also functions which are shared with his neighbor. Nor would this involvement of functions pause with Peter. To make our diagram really representative, each of the two individuals thus far drawn would need to be surrounded by a multitude of others, all sharing in some degree the functions of their neighbors. Or rather each individual, once connected with his neighbors, would find all his functions affected by all those possessed by his entire group. For fear of making my figure unintelligible [Fig 5.]
