Men are born to command or to serve. We cannot wonder, therefore, if in society we see masters and servants, since human nature wills it so. It was all very well for _La Bibliothèque Impartiale_ to repudiate these communist speculations. The point of view from which it itself looked upon social phenomena, the point of view of human nature, it had in common with the Utopian Morelly. And it cannot be urged that this review was probably not sincere in its arguments, and that it appealed to human nature with the single object of saying something in favour of the exploiters, in favour of those who "command." But sincere or hypocritical in its criticism of Morelly, the _Bibliothèque Impartiale_ adopted the standpoint common to all the writers of this period. They all of them appeal to human nature conceived of in one form or another, with the sole exception of the retrogrades who, living shadows of passed times, continued to appeal to the will of God. As we know, this concept of human nature has been inherited by the 19th century from its predecessor. The Utopian Socialists had no other. But here again it is easy to prove that it is not peculiar to the Utopians. Even at the period of the Restoration, the eminent French historian, Guizot, in his historical studies, arrived at the remarkable conclusion that the political constitution of any given country depended upon the "condition of property" in that country. This was an immense advance upon the ideas of the last century which had almost exclusively considered the action of the "legislator." But what in its turn did these "conditions of property" depend on? Guizot is unable to answer this question, and after long, vain efforts to find a solution of the enigma in historical circumstances, he returns, falls back _nolens volens_, upon the theory of human nature. Augustin Thierry, another eminent historian of the Restoration, found himself in almost the same case, or rather he would have done so if only he had tried to investigate this question of the "condition of property" and its historical vicissitudes. In his concept of social life, Thierry was never able to go beyond his master Saint Simon, who, as we have seen above, held firmly to the point of view of human nature.
