_There is no relation whatever between the individual human being’s brain and his individual activities_. But there is the same inexorable law of development by which alone to account for this highest of all brains, and the same relation is plainly to be seen between the social brain and its social activities. No conceivable activities of one biped, through however many generations, could have developed the brain of the architect, for instance. He has the power to think a church. He cannot build a church—never could—never could have even wanted one! The growth of many men, for many ages, brought their common needs, their power of common action, and their brain power to co-ordinate it. You need no power of co-ordination to run one individual animal; the need for social activities developed the social brain. The single human animal could have only needed a single shelter; could have so only built a single shelter, and so have only thought a single shelter. The power of one man to think for many men to do, is a distinctly human power, and evolvable only by the common doing. In our collective relation we have developed a capacity to think, focussed perforce in some individual brain, for the working point of Society is the individual; to think, to the advantage of thousands of people for thousands of years. This organic capacity cannot be accounted for on an individual basis. The laws of natural evolution work to develop in each organism the powers which it most needs; steadily raising the efficient type. The human animal manifests powers of no earthly use to himself, relatable in no way to his personal needs, inexplicable on any individual hypothesis, but plainly useful to Society, relatable to the Social needs, perfectly explicable by the Social hypothesis.
