• If I were to speak your kind of language, I would say that man's only moral commandment is: Thou shalt think.
    But a 'moral commandment' is a contradiction in terms. The moral is the chosen, not the forced; the understood, not the obeyed.
    The moral is the rational, and reason accepts no commandments.
