Document Summary
Five ways to prove god exists by st. aquinas - asks us to observe ef cient causation. Ef cient cause: direct causes, reason something came to be the way it is. Final cause: sake for which something is done, purpose. Aquinas" five ways: from facts about change. The world is such that things are caused by other things, but that has to end somewhere (in nity is not a plausible concept), the causal chain must stop, therefore god is the. Uncaused cause : from facts about possibility and necessity. Some things are better, truer or more noble than others, and there is a thing that is the highest of these things which is god: from the facts about the governance of the world. If everything must have a cause then god must have a cause. If there can be anything without a cause, it may just as well be the world as god.
