Transcendental argument for the existence of God

The Transcendental Argument for the Existence of God (TAG) is the argument that attempts to prove God's existence by arguing that logic, morals, and science ultimately presuppose a supreme being, and that God must be the source of logic and morals. A version was formulated by Immanuel Kant in his 1763 work The Only Possible Argument in Support of a Demonstration of the Existence of God and most contemporary formulations of the transcendental argument have been developed within the framework of Christian presuppositional apologetics.
