In human thermodynamics, the term neguentropy is a variant of the expression "negative entropy". [1] The particular spelling of this term, as compared to more commonplace term "negentropy", seems to be the result of a language translation effect of the Spanish term "neguentropia". [2] The term was also used by French scientific religious philosopher Pierre Teilhard in his writings on evolution, consciousness, and thermodynamics. [3]
