Methodological rules are for science what rules of law and custom are for conduct. - Émile Durkheim

The category of class was at first indistinct from the concept of the human group; it is the rhythm of social life which is at the basis of the category of time; the territory occupied by the society furnished the material for the category of space; it is the collective force which was the prototype of the concept of efficient force, an essential element in the category of causality.

In the name of the dogma of struggle for existence and natural selection, they paint for us in the saddest colors this primitive humanity whose hunger and thirst, always badly satisfied, were their only passions; those sombre times when men had no other care and no other occupation than to quarrel with one another over their miserable nourishment. To react against those retrospective reveries of the philosophy of the eighteenth century and also against certain religious doctrines, to show with some force that the paradise lost is not behind us and that there is in our past nothing to regret, they believe we ought to make it dreary and belittle it systematically. Nothing is less scientific than this prejudice in the opposite direction. If the hypotheses of Darwin have a moral use, it is with more reserve and measure than in other sciences. They overlook the essential element of moral life, that is, the moderating influence that society exercises over its members, which tempers and neutralizes the brutal action of the struggle for existence and selection. Wherever there are societies, there is altruism, because there is solidarity.

It is society which, fashioning us in its image, fills us with religious, political, and moral beliefs that control our actions.
