“Only a fool believes something without proof. To simplify that for you: only a fool relies on faith.”

Interesting assertion.

1 Cor 2:1-5 – And when I came to you, brethren, I did not come with superiority of speech or of wisdom, proclaiming to you the testimony of God. For I determined to know nothing among you except Jesus Christ, and Him crucified. I was with you in weakness and in fear and in much trembling, and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, so that your faith would not rest on the wisdom of men, but on the power of God.

1 Cor 2:10-14 – For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God. For who among men knows the thoughts of a man except the spirit of the man which is in him? Even so the thoughts of God no one knows except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, so that we may know the things freely given to us by God, which things we also speak, not in words taught by human wisdom, but in those taught by the Spirit, combining spiritual thoughts with spiritual words. But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised.

Note: The assertion of the atheist I quoted seems to be that they have something else to rest their knowledge on. They are merely making a negative epistemological claim, with no positive claim to be found, however. In fact, their claim is in accordance with the Scripture above – that our epistemological claim is foolishness to them. The reason this is so, is because it is *spiritually* discerned. On the contrary, we claim that their epistemological claims are foolishness, from the standard of our worldview. This is the antithesis that exists between the wisdom of the world, and the wisdom of God.

Here is where transcendental argument comes in. Their claim to knowledge is unintelligible from their worldview. There is no basis to assume that 1) They exist to know what they claim to know 2) That what they claim to know has any sort of intelligible relationship to anything else they claim to know 3) That their epistemological basis (self) is capable of providing the preconditions of intelligibility.

The claim “I know” (x) has a precondition – (y) the Triune God of Scripture. That is the only means by which “I know” has the preconditions of intelligibility. Only in the revelation of the Triune God in His Scripture is there is an absolute, self-sufficient, self-existent, eternal and immutable (not excluding attributes, but eliding for the sake of space – see here for more on this topic) source who can communicate with us, and gives us those preconditions. Since x is only preconditioned by y, y is true, and ~y is impossible.

Since we have this absolute, objective epistemological foundation, and the unbeliever has no foundation whatsoever to stand on, epistemologically, on what basis does “a fool rely on faith”? Self has no epistemological foundation. Self has no absolute reference. Self can’t justify self, induction, deduction, or intelligibility, for that matter. Yet, we’re told that Descartes “I think, therefore I am” is a starting point? What does “I think” assume? The consequent, “I am”. It’s circular. My existence is only made intelligible by the Triune God of Scripture. The unbeliever’s existence is made intelligible by what, by His standard? Until the unbeliever can offer me a justification for his own claims, and demonstrate that he knows what he’s denying, we can safely say that this assertion is empty rhetoric, countered by an argument with content.
