The cosmological argument is a metaphysical argument for the existence of God, or a first mover of the cosmos. It is traditionally known as an "argument from universal causation," an "argument from first cause," and also as an "uncaused cause" 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."Origins of the argument
Plato and Aristotle both posited first cause arguments, though each had certain notable caveats. Plato (c. 427–c. 347 BCE) posited a basic cosmological argument in The Laws (Book X). He argued that motion in the world and in the cosmos was "imparted motion" that would have required some kind of "self-originated motion" to set it in motion and to maintain the motion. Plato also posited a "Demiurge" of supreme wisdom and intelligence as the creator of the cosmos in his work Timaeus.
