"Man experiences a multitude of needs, on whose satisfaction his happiness depends, and whose non-satisfaction entails suffering. Alone and isolated, he could only provide in an incomplete, insufficient manner for these incessant needs. The instinct of sociability brings him together with similar persons, and drives him into communication with them. Therefore, impelled by the self-interest of the individuals thus brought together, a certain division of labor is established, necessarily followed by exchanges. In brief, we see an organization emerge, by means of which man can more completely satisfy his needs than he could living in isolation. This natural organization is called society. The object of society is therefore the most complete satisfaction of man's needs. The division of labor and exchange are the means by which this is accomplished."
