Just believed that "life as an event lies in a combination of chemical stuffs exhibiting physical properties; and it is in this combination, i.e., its behavior and activities, and in it alone that we can seek life.". He also wrote: "is the harmonious organization of events, the resultant of a communion of structures and reactions", and "We [scientists have often striven to prove life as wholly mechanistic, starting with the hypothesis that organisms are machines! Living substance is such because it possesses this organization--something more than the sum of its minutest parts" He argued forcefully that the "ectoplasm," the outer region of the cytoplasm, and not the nucleus, constitutes the heart of the dynamic cell. He was convinced that the surface of the egg cell possesses an "independent irritability," which enables the egg (and all cells) to respond productively to diverse stimuli.
