 An interesting wrinkle in Cavendish’s view of the orderly behavior of bodies is her insistence that when bodies interact they do not transfer motion to each  other.[28]  Instead, bodies communicate with each other about how to coordinate their behavior, and each is then the source of its own motion. On the assumption that properties cannot literally slide or hop from one body to another, cases in which one body does take on the motion of another body would be cases in which the second body also takes on the matter that has that motion. But we do not observe a body to become more massive when it is moved as a result of its contact with another body. As Cavendish explains in her description of a hand that moves a bowl,
