Human Chemistry (spine view) Human Chemistry (annotated)
Libb Thims' 2007 Human Chemistry originated from a desire and curiosity to understand how human reproduction reaction is understood and explained via Gibbs energy and spontaneity criterion prediction methodology.
In human chemistry, the Human Chemistry (textbook) (origin) page discusses the origin of the 2007, two-volume, 824-page textbook Human Chemistry written by American chemical engineer Libb Thims. [1] The gist reason the textbook was written was that prior to 2007 the subject of people viewed as reactive chemical entities (A, B, C), forming combinations:

A + B → C

and partaking in separations:

C → A + B

where C is the the dihumanide molecule (two human molecules bonded as one unit, such as in a marriage) and A and B are unattached single humans, had never before been presented as a basic subject using standard chemistry principles extrapolated up to the human chemical reaction scale. In Thims' mindset, however, he had assumed this to be a basic subject that everyone was aware of, not needing introduction, being that he had been working on these types of reactions in the twelve years prior, albeit focused on how enthalpy and entropy changed over the course of the reaction. This subject, prior to 2001, had been purely a intellectual hobby for Thims. When, however, he began to go public with his findings and theoretical development, in circa 2003, he found huge barriers to discussion on this subject (human chemistry), which further detracted dialog on the subject he was primarily interested in, that being human thermodynamics. Subsequently, the human chemistry textbook was written to remedy this obstacle.

Textbook origin
See main: Libb Thims (history)
The first main thing that spurred the writing of the textbook was (a) the discovery, sometime in circa 2005, of 2001 online Q&A page 'Is Love a Purely Chemical Reaction' of the Physics Van Outreach Program of the physics/engineering department of the University if Illinois, Champaign-Urbana, in which it was explained to a seven-year-old child that love is not a purely chemical reaction. The specific answer given was:

“No, I don’t think love is a purely chemical reaction. Love is more a question in the realm of philosophy than science. I think you could ask anyone who’s ever been in love, and they’d probably agree that there’s something more to it than simple chemistry.”

Spurred by this incorrect response, in 2005, Thims polled one-hundred people with this very same question (is love a purely chemical reaction?) and found that 66 percent of people agreed that love is a purely chemical reaction, thus showing the above response to be an inaccurate viewpoint.

The second main thing that spurred the writing of the textbook was (b) the discovery, sometime in early 2006, of footnote 2.5 of Belgian chemist Ilya Prigogine’s 1984 book Order out of Chaos, which reads: [2]

Dobbs, op. cit., also examined the role of the ‘mediator’ by which two substances are made ‘sociable’. We may recall here the importance of the mediator in Goethe’s Elective Affinities (Engl. Trans. Greenwood 1976). For what concerns chemistry, Goethe was not far from Newton.
Footnote #5 (pgs. 64, 319), chapter II: The Identification of the Real, section 2: Motion and Change, Order Out of Chaos (1984) by Ilya Prigogine.

At the the time of the reading of this footnote, strangely enough, even though Thims is 50% German, and had at that time over 750 science books in his personal library collection, he had never heard of Goethe. In any event, after finally reading Elective Affinities, specifically the famous chapter four, it was what drove Thims (or rather instilled in him the duty) to write the world’s first uniform textbook on the subject of human chemistry, basically the modern science (chemistry and physics) view of what Goethe was theorizing about 200 years ago. In the core chapter of the book, chapter ten 'Goethe's Affinities', Goethe is defined as 'the founder of human chemistry', for his pioneering work.
