To give a decent representative quote: "Our theory of the origin of life is that there is no origin, but only a constant development and change of form." He mixes this in with discussions of endothermic and exothermic movements of matter in relation to animate matter (humans) and inanimate matter (food), into and out of the body, in way that seems to foreshadow the concept of free energy coupling developed in the 1920s through the 1940s, all in relation to chemical experiments and findings, such as the Haber process.
