One seeks behind the subjectively experienced appearance the object — something materially concrete. One does not find this in warmth itself, but only secondarily in the thermal states that appear measurably in the elements of the solid, the fluid, and the gaseous. Warmth would remain imperceptible without this reference to the three elements or states of aggregation. For Francis Bacon, who with juridical means made himself judge over warmth, this was presumably the ground for denying warmth any independent existence as an element. To this day the immateriality of warmth, its essential nature, remains conceptually in the dark. It embodies no state of aggregation of its own. In more recent times, researchers have tended to designate the energy-rich, highly rarefied state of plasma as a fourth state of aggregation. Yet even in this highly complex context of appearances, warmth occurs in matter-bound form. Its pure nature as warmth-element becomes in perception the phenomenon of warmth-sensation in the gradations from cold to hot, mediated through the elements of earth, water, air. Furthermore, its pure immaterial nature reveals itself in the property of transferring, through its presence and absence, the elemental or aggregate states into one another.
