I am saying that any concept, like "reality" (and its components, e.g., the possible thinking of machines) is delimited in "fact" by the capacity of language to express it.

Oh yeah. Definitely. I was wishing today that there was a word that, when used, we would know would not mean a physical feeling, but another, internal-only, kind. Maybe two: one for emotion-feeling, and another for, um (speaking of inadequate lang.), lack of a better term I'll call mental feeling, as in, "I've got a feeling that will not work out". For instance, if I say I felt warm, without context no one can tell if I mean temperature-wise, or the warm feeling I get from a message that virtually radiates warmth.
