"There are two ways of considering society. According to some, the development of human associations is not subject to providential, unchangeable laws. Rather, these associations, having originally been organized in a purely artificial manner by primeval legislators, can later be modified or remade by other legislators, in step with the progress of social science. In this system the government plays a preeminent role, because it is upon it, the custodian of the principle of authority, that the daily task of modifying and remaking society devolves. According to others, on the contrary, society is a purely natural fact. Like the earth on which it stands, society moves in accordance with general, preexisting laws. In this system, there is no such thing, strictly speaking, as social science; there is only economic science, which studies the natural organism of society and shows how this organism functions."
