 There are two causal orders or dimensions governing the production and actions of particular things. On the one hand, they are determined by the general laws of the universe that follow immediately from God’s natures. On the other hand, each particular thing is determined to act and to be acted upon by other particular things. Thus, the actual behavior of a body in motion is a function not just of the universal laws of motion, but also of the other bodies in motion and rest surrounding it and with which it comes into contact.
