These are the things I demand of you--however badly they may sound in
your ears: that you subject moral valuations themselves to criticism.
That you should put a stop to your instinctive moral impulse--which in
this case demands submission and not criticism--with the question: "why
precisely submission?" That this yearning for a "why?"--for a criticism
of morality should not only be your present form of morality, but the
sublimest of all moralities, and an honour to the age you live in. That
your honesty, your will, may give an account of itself, and not deceive
you: "why not?"--Before what tribunal?
