The word body, in the most general acceptation, signifieth that which filleth or occupieth some certain room or imagined place; and dependeth not on the imagination, but is a real part of that we call the universe. For the universe, being the aggregate of all bodies, there is no real part thereof that is not also body; nor anything properly a body that is not also part of that aggregate of all bodies, the universe.
