But that which, was faintly indicated among lower beings is conspicuously displayed among human beings—that the advantages of co-operation can be had only by conformity to certain requirements which association imposes. The mutual hindrances liable to arise during the pursuit of their ends by individuals living in proximity, must be kept within such limits as to leave a surplus of advantage obtained by associated life. Some types of men, as the Abors, lead solitary lives, because their aggressiveness is such that they can not live together. And in view of this extreme case it is clear that though, in many primitive groups, individual antagonisms often cause quarrels, yet the groups are maintained because their members derive a balance of benefit—chiefly in greater safety. It is also clear that in proportion as communities become developed and their division of labor complex, the advantages of co-operation can be gained only by a still better maintenance of those limits to each man's activities necessitated by the simultaneous activities of others. This truth is illustrated by the unprosperous or decaying state of communities in which the aggressions of individuals on one another are so numerous and great as to prevent them from severally receiving the normal results of their actions.

The requirement that individual activities must be mutually restrained, which we saw is so felt among certain inferior gregarious creatures that they inflict punishments on those who do not duly restrain them, is a requirement which, more imperative among men, and more distinctly felt by them to be a requirement, causes a still more marked habit of inflicting punishments on offenders. Though in primitive groups it is commonly left to any one who is injured to revenge himself on the injurer, and though even in the societies of feudal Europe, the defending and enforcing of his claims was in many cases held to be each man's personal concern; yet there has ever tended to grow up such perception of the need for internal order, and such sentiment accompanying the perception, that infliction of punishments by the community as a whole, or by its established agents, has become habitual. And that a system of laws enacting restrictions on conduct, and punishments for breaking them, is a natural product of human life carried on under social conditions, is shown by the fact that among multitudinous nations composed of various types of mankind, similar actions, similarly regarded as trespasses, have been similarly forbidden.

Through all which sets of facts is manifested the truth, recognized practically if not theoretically, that each individual carrying on the actions which subserve his life, and not prevented from receiving their normal results good and bad, shall carry on these actions under such restraints as are imposed by the carrying on of
