All known living bodies are sharply divided into two special kingdoms, based upon the essential differences which distinguish animals from plants, and in spite of what has been said, I am convinced that these two kingdoms do not really merge into one another at any point.

FAUSTUS: How many heavens or spheres are there?
MEPHASTOPHILIS: Nine: the seven planets, the firmament, and the empyreal heaven.
FAUSTUS: But is there not coelum igneum, et crystallinum?
MEPH.: No Faustus, they be but fables.
FAUSTUS: Resolve me then in this one question: Why are not conjunctions, oppositions, aspects, eclipses all at one time, but in some years we have more, in some less?
MEPH.: Per inaequalem motum respectu totius.
FAUSTUS: Well, I am answered. Now tell me who made the world.
MEPH.: I will not.
FAUSTUS: Sweet Mephastophilis, tell me.
MEPH.: Move me not, Faustus.
FAUSTUS: Villain, have I not bound thee to tell me any thing?
MEPH.: Ay, that is not against our kingdom.
This is. Thou are damn'd, think thou of hell.
FAUSTUS: Think, Faustus, upon God that made the world!
MEPH.: Remember this.
