Antiphlogistic philosophy

Lavoisier now considered the phlogiston theory as virtually overthrown, and turned to the organization of his new philosophy, called for a time the antiphlogistic philosophy and now recognized generally as the foundation of the modern theory of oxidation and reduction. 

Kirwan exhibited no less courtesy toward his opponents. Lavoisier, the main author of the antiphlogistic hypothesis and a philosopher of great eminence, was the first that introduced an almost mathematical precision into experimental philosophy. Kirwan also acknowledged many of his opponents positive contributions, such as proving that the weight gain of metals was due to the air fixed in the process and that the atmosphere consisted of two distinct airs.
