19th-century scientific controversy

Energeticism, also called energism or energetics (), is a superseded theory in science that posits that energy is the ultimate element of physical reality. Energeticism was developed during the end of the 19th century by Wilhelm Ostwald, Georg Helm and Pierre Duhem. It was also promoted by physicist Ernst Mach who opposed atomic theory, though his full commitment to it was sometimes ambiguous. Energetiscism attempted to substitute the hypothesis of atoms and molecules by energy relations.
