Sidis wrote The Animate and the Inanimate to elaborate his thoughts on the origin of life, cosmology, and the potential reversibility of the second law of thermodynamics through Maxwell's Demon, among other things. It was published in 1925, but it has been suggested that Sidis was working on the theory as early as 1916. One motivation for the theory appears to be to explain psychologist and philosopher William James's "reserve energy" theory, which proposed that people subjected to extreme conditions could use "reserve energy". Sidis' own "forced prodigy" upbringing was a result of testing the theory. The work is one of the few that Sidis did not write under a pseudonym. - Summary by Wikipedia
