Moving Bodies Are Urged at an Uniform Velocity Never to Be Annihilated

Abstract

We demonstrated that not all bodies are moved by a distinct and separate motor. But finally we must consider the moving subject which moves by itself. It seems incredible of course that his motive impetus could not be impressed by God the creator into some bodies when he created them. A projected body, colliding with an immobile and movable hanging body, was allowed to be able to impress into this a degree of impetus thanks to which the body can be displaced afterwards. Consequently, although in the nature of things bodies are supposed to be absolutely inert and immobile, some spirituous and lively bodies must also be admitted.
