"At the roots of all our judgments there are a certain number of essential ideas which dominate all our intellectual life; they are what philosophers since Aristotle have called the categories of the understanding: ideas of time, space, class, number, cause, substance, personality, etc. They correspond to the most universal properties of things. They are like the solid frame which encloses all thought: this does not seem to be able to liberate itself from them without destroying itself."

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

“When, then, the sociologist undertakes the investigation of some order of social facts, he must endeavour to consider them from an aspect that is independent of their individual manifestations.”

“Kant postulates God, since without this hypothesis morality is unintelligible. We postulate a society specifically distinct from individuals, since otherwise morality has no object and duty no roots.”

“To pursue a goal which is by definition unattainable is too condemn oneself to a state of perpetual unhappiness.”

“Division of labour produces solidarity only if it is spontaneous and in proportion as it is spontaneous. But by spontaneity we must understand not simply the absence of all express violence, but also of everything that can even indirectly shackle the free unfolding of the social force that each carries in himself. It supposes, not only that individuals are not relegated to determinate functions by force, but also that no obstacle, of whatever nature, prevents than from occupying the place in the social framework which is compatible with their social faculties. In short, labour is divided spontaneously only if society is constituted in such a way that social inequalities exactly express natural inequalities”

“Men already had ideas on law, morality, the family, the state, and society itself before the advent of social science, for these ideas were necessary conditions of his life”
