It was the passion for power that led to the first social groupings and developed the social instincts. Our varied sympathies, our parental and filial impulses, our heroisms and generosities, all go back to social habits born of individual needs. “Since fear of solitude exists in all men, because no one in solitude is strong enough to defend himself and procure the necessaries of life, it follows that men by nature tend towards social organization.”[106] “Let satirists scoff at human affairs as much as they please, let theologians denounce them, and let the melancholy, despising men and admiring brutes, praise as much as they can a life rude and without refinement,--men will nevertheless find out that by mutual help they can much more easily procure the things they need, and that it is only by their united strength that they can avoid the dangers which everywhere threaten them.”[107] _Nihil homine homini utilius._ Men discover that they are useful to one another, and that mutual profit from social organization increases as intelligence grows. In a “state of nature”--that is, before social organization--each man has a “natural right” to do all that he is strong enough to do; in society he yields part of this sovereignty to the communal organization, because he finds that this concession, universalized, increases his strength. The fear of solitude, and not any positive love of fellowship, is the prime force in the origin of society. Man does not join in social organization because he has social instincts; he develops such instincts as the result of joining in such organization. VIII Freedom and Order
