 The view that space and time are actual entities is meant to represent the Newtonian position, and the view that they are determinations or relations of things, the Leibnizian position (but cf. Hatfield 2006, 77–8). Later in the Transcendental Aesthetic, he refers to the Newtonians as the “mathematical investigators” of nature, who contend that space and time “subsist” on their own, and to the Leibnizians as the “metaphysicians of nature,” who think that space and time “inhere” in objects and their relations (see A39–40/B56–57).
