An opinion, right or wrong, can never constitute a moral offense, nor be in itself a moral obligation. It may be mistaken; it may involve an absurdity, or a contradiction. It is a truth; or it is an error: it can never be a crime or a virtue.
Frances "Fanny" Wright (1795-1852) Scottish-American writer, lecturer, social reformer
