Those who take ruling ideas for truth have already lost the freedom of thought, not to mention the freedom of speech. That is why under normal American conditions of capitalism the state seldom has to go so far as to employ fascist measures to censor speech. Quite a few have already censored themselves, _and_ they think they are "free." To rewrite Rousseau, "Man is born free; and everywhere he is in chains. One thinks himself the master of his own ideas, and still remains a slave."
