The Measurement of Human, All Too Human Things

Kant's response to Protagoras focuses primarily not on the measuring, but on the measured--his innovative thesis restricts the range of what is measurable by humans to phenomena.  In other words, his alternative dictum can be expressed as 'Man is the measure of only some things.'  However, he does not propose more strongly that 'Man is the only measure of phenomena', since he allows that they may be conditioned by noumena.  Likewise, Nietzsche, for the most part, allows that the measure of human, all too human things may be Dionysus or an Overman.  The one notable exception for him is Architecture, which he considers too late in his career for it to be a touchstone to a doctrine that can be more decisively formulated as 'Man is the only measurer of human, all to human things.
