The argument breaks down for me here:

> because the experience of wet is wholly subjective.

I can't distinguish this from "wetness is a quale." In which case the analogy water : wetness :: brain : qualia reduces to water : qualia :: brain : qualia.

Also:

> the experience of having experiences

The fact that we sometimes slip up and use recursive language like this is a suggestive sign to me. We intuit that experience is somehow "already present," or fundamental, as idealism claims. If idealism is true, then you _are_ consciousness, and already know it at some level.
