"Oppression tries to defend itself by its utility. But we have seen that it is one of the lies of the serious mind to attempt to give the word “useful” an absolute meaning; nothing is useful if it is not useful to man; nothing is useful to man if the latter is not in a position to define his own ends and values, if he is not free. Doubtless an oppressive regime can achieve constructions which will serve man: they will serve him only from the day that he is free to use them; as long as the reign of the oppressor lasts, none of the benefits of oppression is a real benefit. Neither in the past nor in the future can one prefer a thing to man, who alone can establish the reason for all things."
