transcendal argument for the existence of gawd

Transcendental arguments start from some accepted aspect of experience, and then deduces what must be true for that experience to be possible.In the case of TAG, we start with logic, reason, and knowledge. It's argued that our logic is inherently circular (we use logic to create a hypothesis and then (dis)prove that hypothesis with logic). Therefore, we must conclude God is the source of our logic in order to avoid an infinite regress. An infinite regress in a series of propositions arises if the truth of proposition P1 requires the support of proposition P2, the truth of proposition P2 requires the support of proposition P3, ... , and the truth of proposition Pn-1 requires the support of proposition Pn and n approaches infinity.

refutation :

The main response to TAG revolves around the premise: "without a god, knowledge cannot exist." If the premise is indeed accepted, it can lead to the conclusion a god does exist, but the argument provides no demonstrated necessity to accept this premise. A transcendental argument for the non-existence of God has been put forward that uses the same unsubstantiated premise that "the existence of knowledge presupposes the non-existence of God.
