The cosmological argument is a metaphysical argument for the existence of Go, or a first mover of the cosmos. It is traditionally known as an "argument from universal causation", an "argument from first cause", "The Causal Argument" and also as an "uncaused cause" or "unmoved mover" argument. Whichever term is used, there are three basic variants of this argument, each with subtle but important distinctions: the argument from causation in esse, the argument from causation in fieri, and the argument from contingency. The cosmological argument does not attempt to prove anything about the first cause or about God, except to argue that such a cause must exist. This cause is known in Latin as "causa sui".
