“The ground for morality can only be prepared when a greater individual or collective-individual, as, for example, society or state, subjects the individuals in it, that is, when it draws them out of their isolatedness and integrates them into a union. Force precedes morality; indeed, for a time morality itself is a force, to which others acquiesce to avoid unpleasere. Later it becomes custom, and still later free obedience and finally almost instinct: then it is coupled to pleasure, like all habitual and natural things, and is now called virtue.”
