"Society is not homogeneous, and those who do not deliberately close their eyes have to recognize that men differ greatly from one another from the physical, moral, and intellectual viewpoints."

“Men follow their sentiments and their self-interest, but it pleases them to imagine that they follow reason. And so they look for, and always find, some theory which, a posteriori, makes their actions appear to be logical. If that theory could be demolished scientifically, the only result would be that another theory would be substituted for the first one, and for the same purpose.”

“The economic and social theories used by those who take part in the social struggle ought to be judged not by their objective value but primarily for their effectiveness in arousing emotions. The scientific refutation of them which can be made is useless, however correct it may be objectively.”

“Empirical laws have only slight or even no value beyond the limits within which they have been observed to be true.”

“When it is useful to them, men can believe a theory of which they know nothing more than its name.”

“Usually, so far as improvement in the people's economic conditions is concerned, humanitarians simply play the role of the busybody.”

“The assertion that men are objectively equal is so absurd that it does not even merit being refuted.”
