What are these substances that are moved back and forth in their various forms of appearance? What is a substance? Substances appear in the four classical elements: in the states of aggregation of the solid (earth), the fluid (water), the gaseous (air). For the element of warmth, natural science has not yet found a conceptual access that would characterize it as an independent fourth among the classical elements. To this day, the methodological principle of the dissection of phenomena continues to hold sway — a principle that goes back to the founder of experimental physics, Francis Bacon (1561–1626). This method, of seeking behind the phenomena the causative principle of being in material processes, still governs the common scientific enterprise today.
