Searle should dispute the premise that contains "every physical fact."

Presumably, my seeing red is also a physical fact.  Conceptual dualists may 
whine, though.  But so what?

The hardness of a piston does work at a system level and the consciousness of a 
brain allows for meaningful traffic signals.

I suppose one can all the facts (physical ones) without the fact that some red 
light means to stop.  Ergo, there is more to the world than is found in physics.

I don't think that follows but may be a paralogism of reason or some such.
