A SYSTEM OP PHYSICAL CHEMISTRY

The confusion of thinking that Kant only focuses on physics in the OP arises, because it is true that Kant often uses the term physics to cover both physics and chemistry. For example (22 501) As a science of experience, however, physics is naturally divided into two subjects. The one is the subject of the forms in action and reaction of forces in space and time. The other is the complex of the substances which fill space. The one could be called the systematics of nature, the other is called (following Linnaeus) the system of nature. However, otherpassages make clearthat he might also call the former physics and the latter chemistry (see citations in note 49). In the end, the question whether Kant would locate his gap or transition in connection with physics or chemistry is neither here nor there.
