  Throughout the Guide, Maimonides considers four accounts of creation: that of the kalam, Moses, Plato, and Aristotle. He rejects the kalam account (GP 1.71–73) according which one demonstrates that the universe must have been created and then reasons that if it was created, it must have a creator. Like Thomas Aquinas, Maimonides believes it is impossible to show by logical considerations alone either that the universe was created or that it is eternal. Though Maimonides says he believes in creation, he admits one can do no more than tip the scales in this direction. As of Guide 2.13, he limits his discussion to the theories of Moses, Plato, and Aristotle.
