Frederick Engels claimed that justice was "social phlogiston." (40) In trying to make irreducible moral properties explain social regularities just as chemists before Lavoisier tried to make phlogiston explain combustion, nonreductionism fails just as phlogiston theories failed.
Insofar as one wishes to talk of my analysis in terms of being a reduction, it would be a retentive, and not an eliminativist, reduction: the target phenomenon, detached statements, is to be retained, and not eliminated like phlogiston.

At the time, chemistry was still in its infancy--barely a generation removed from theories rooted in flows of phlogiston. Over the course of the next half-century, however, researchers such as Justus von Liebig, Jean-Baptiste Boussingault, and Sir Joseph Henry Gilbert significantly advanced the world's understanding of agricultural processes.

" Priestley, though, didn't recognize the gas as an element, calling it "dephlogisticated air," in light of the prevailing belief that flammable materials contained phlogiston, a substance without colour, odour, taste, or weight that was given off during combustion.
Here we learn of the contributions of Boyle, Hooke, Mayow, and Becher in solving the riddles of combustion and respiration, as well as introducing the first theory of chemistry: phlogiston. The fifth, and longest, section of the book is devoted to the chemical revolution that occurred during the late 18th century.
(44) I have argued that the very precariousness of chemistry--a field perched between the phlogiston and oxygen theories, between magical and rational explanations, between the machine-like logic of combinatorics and the anthropomorphic theory of affinity--makes it into a particularly fitting allegory of the poetical model Schlegel develops.
Constant changes in theories of etiology and cure no more condemn psychiatric science than outdated theories of phlogiston or ether discredit chemistry or physics.
