I don’t think I understand what you think is and isn’t a “posit”. “Cold” is a prima facie phenomenon as well, but it has been subsumed entirely into the concept of “heat”.
The prima-facie phenomenon of “cold” (as in “your hands feel cold”) has been subsumed under the scientific theory of heat-as-random-molecular-motion. That’s reduction. it was never eilmininated in favour of the prima-facie phenomenn of heat, as in “This soup is hot”.
