An example of an historical alternative scientific conception:
"The contrast between Bacon's pretensions and the measure of success achieved in his works, has made him as easy prey for his detractors. His language and his thought sometimes closely resemble that of the Schoolmen at whom he scoffed. The Idols that he described with such insight sometimes mislead their author himself, as when in his study of heat, he promises us a study of cold, not noticing apparently, that hot and cold are relative terms."
Brown, G. Burniston (1950) Science. Its method and its philosophy. London. George Allen & Unwin Ltd.
Bacon was not the only natural philosopher/scientist who saw 'cold' as a distinct factor/phenomenon to heat.
