Abstract Unlike most in his age, Kant was a constant and forceful defender of action at a distance. In virtue of this advocacy, he counts as a spokesman for Newtonian science. Less known are his views on contact interactions. As it rurns out, Kant developed these views so as to fulfill a foundational agenda inherited form Leibniz not Newton. This agenda required natural philosophers to show that action by contact is (1) intelligible, and (2) grounded in an a priori dynamics. To solve this dual problem, Kant draws on his metaphysics of motion and matter.

In Part 1, I present the early Kant's mechanics of contact action. At its heart is a concept of relative motion. I explain the peculiar sense of Kantian relativity, and how Kant developed so as to solve a problem bequeathed by Leibniz. Then I document how this a priori mechanics survives in Kant's Critical period.

Leibniz had complained that contact action -- paradigmatically, collision -- appears unintelligible, because it seems to involve a transfer of properties. In Part 2, I explain how the young Kant draws on his matter theory to avoid the unintelligibility charge. However, Kant's solution involves short-range action at a distance forces -- unacceptable to Leibniz but at home in Newton's system. In the 1780s, Kant switches to a doctrine of matter as a physical continuum. This brings him closer to Leibniz, but it threatens to break apart his concepts of force and matter.
