As was defined in the link, which is to say subjective experience/sensation, that which cannot be defined. I'm not convinced that contemplating "consciousness" does require this aspect of consciousness. This is because I draw a large question mark across anything relating to consciousness. I have yet to hear any sound explanation as to how physical brain states translate into subjective experience, explanations of said experiences, and cannot think of any myself. I reach a perpetual headache point when I get into it, a logical line that can't seem to ever be crossed. The best I can do is throw my hands up, say, "maybe it's all just an act of faith", and think the entire world is a logical paradox within a paradox, one which human reason is unable to explain. Maybe science will prove me wrong, but I don't even see it in the potential category yet. On topic: why is God "He" and not "It"? Just men being men?
