Uh uh. Consciousness, or even awareness. My experience of, say the
color blue at some place in my visual field is a fact. I know it is a
fact. Others can reasonably rely upon it being a fact, since they
experience the same color -- or at least a color we all refer to as
"blue" -- when they observe the same external object.
However, my inner "blue" though quite real and factual, cannot be
observed by any external observer. It is not measurable, it is difficult
to formulate a theory about, but it /is/ known.
