“Dobereiner helped in refining Russian platinum, discovered catalysis, and reported his work to Goethe. We can only suspect that they both discussed this and that Dobereiner read the tragedy Faust and the novella Elective Affinities. The latter work of art gave impulse to a new scientific field named 'human chemistry'.
In the exact sciences there are quantitative measures of estimation of each value: mass, length, force, energy. In the humanistic disciplines (history, philosophy, psychology) as well as art there are no quantitative criteria. This is similar to the question of how to measure beauty, love, friendship, democracy? The function named Gibbs energy defines ‘love’ between substances [and] people [?] ... and is similar to Hamlet’s ‘to be or not to be?’ of William Shakespeare.”
