  Kant's views on chemistry have not been widely discussed in the secondary literature. However, outstanding discussions of Kant's views on the topic can be found in Carrier (1990, 2001) and Friedman (1992, chapter 5, III). Lequan (2000) is a philosophical survey of Kant's thought on chemistry throughout his development. McNulty (forthcoming) explains why Kant takes chemistry to miss the threshold for proper science – specifically, the sense in which chemistry is not mathematizable, in Kant's view.
