Transcendental argument for the existence of God

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. C. S. Lewis's argument from reason is also a kind of transcendental argument.

Most contemporary formulations of a transcendental argument for God have been developed within the frameworkofChristian presuppositional apologetics and the likes of Cornelius Van Til and Greg Bahnsen.^[2]

Transcendental reasoning[edit]

"Transcendental" in this case is used as an adjective specifying a specific kind of argument, and not a noun. Transcendental arguments should not be confused with arguments for the existence of something transcendent. Rather, transcendental arguments are arguments that make inferences from what is necessarily true to possibly think and experience.

Transcendental arguments take the form of modus ponens:

If possibly P, then necessarily Q.

Actually P.

Therefore, necessarily Q.

They are also sometimes said to be distinct from standard deductive and inductive forms of reasoning, although this has been disputed, for instance by Anthony Genova^[3] and Graham Bird.^[4]

The argument[edit]

There are many variants of the transcendental argument for the existence of God, but they generally proceed as follows:^[5]

1. If there is a transcendental unity of apperception, God exists.
2. There is transcendental apperception.
3. Therefore, God exists.

The TAG differs from thomistic and evidentialist arguments, which posit the existence of God in order to avoid an infinite regress of causes or motions.

Ash'ari[edit]

Medieval Ash'ari Islamic theologians formulated a type of transcendental argument based on the notion that morality, logic, etc. cannot be fully understood apart from revelation and thereby, belief in the Quran and the Islamic truth claims were necessary in order to interpret the external world. For al-Ashari and others, it does not make sense to argue against religion using a priori assumptions about morality or scientific probabilities when these can only be understood in light of divine revelation.^[6]

Criticism[edit]

Barry Stroud has criticized transcendental arguments, distinguishing between epistemic and metaphysical transcendental arguments. The former says the belief in God (which might be false) is necessary to make sense of the world, while the latter says the existence of God is necessary to make sense of the world. Stroud argues transcendental arguments often only establish the former, but assert the latter.^[7]

Presuppositional apologetics[edit]

Internet Infidels co-founder Jeffery Jay Lowder has argued that the presuppositional apologetics' version of TAG is fatally flawed for numerous reasons.^[8] First, Bahnsen fails to defend the necessity of Christianity instead of the mere sufficiency for the rational justification of the laws of logic, the laws of science, and the laws of morality. In other words, such reasoning affirms the consequent. Second, Bahnsen conflates "atheism" with "materialism" and has really presented an argument against materialism, not an argument for Christianity. Third, Bahnsen believed that the laws of logic, laws of science, and laws of morality are abstract objects, but Christianity arguably underdetermines the relationship between God and abstract objects. Some Christian philosophers, such as Peter van Inwagen, affirm Platonism and the compatibility of God and abstract objects. But other Christian philosophers argue that Platonism is incompatible with divine aseity. William Lane Craig urges Christian philosophers to consider anti-realist theories of abstract objects.^[9]
