The way I see it, atheists don't have to invoke a personal God after seeing this argument. The only people in trouble are atheistic naturalists. But for someone such as myself who doesn't believe naturalism is coherent, I have no problems. Therefore, I propose a third alternative (to naturalism and theism) which states that qualia guarantees that I'm in a proper relationship with reality: if I experience greenness, then that can only mean there's greenness out there *to be experienced*. After all, my experiences are partly nothing more than causal relations that began with inputs from the *external* world that I then receive and make sense of.
"It is the mark of an educated mind to be able to entertain a thought without accepting it" ~ Aristotle
