Presuppositional apologetics acknowledges that its arguments (and ultimately every argument) are circular. At its most basic and foundational level, every belief is taken on faith. Starting with this fact, here’s how a defense of Christianity might move on to account for the “preconditions of intelligibility” while exposing that contrary worldviews cannot, and then lead into an evangelistic opportunity.
Skeptic: Any argument for the truth of Christianity is a circular argument. Instead of appealing to reason, you are appealing to your own conclusion as your premise. You are saying the Bible is true because the Bible is true.
Believer: Arguing for the existence of God is a circular argument, that much is true. But any argument for ultimate commitment is circular.
Skeptic: But I argue using reason.
Believer: So do I, but reason is your ultimate commitment. Your defense of reason by reason is circular. You and I both hold to circular arguments in supporting our ultimate commitments. The difference is that Christianity provides a basis for the reason we both use in the argument. The eternal and all-knowing God described in the Bible is a God of reason, who created man in His image. We can reason because God endowed us with it and invites us to use it. But without appealing to God, you can’t account for your use of reason.
Skeptic: I can account for reason by the fact that there is knowledge.
Believer: If the universe is basically matter in motion, how can your worldview account for knowledge? If knowledge is your ultimate commitment, your ultimate authority, then your use of knowledge to explain knowledge is still circular. What can knowledge appeal to? God has a mind and we’re made in His image, according to the Bible. Christians can actually make sense of knowledge.
Skeptic: I don’t have to explain why there is knowledge and reason. There are plenty of phenomenon left for us to discover, but it will be discovered through science, not religion.
Believer: In order to do science, we presuppose predictability and uniformity in nature. Why do you assume that you can expect certain results from experiments based on what happened in the past? There’s no scientific basis for uniformity that other than past experience of uniformity, but the Bible explains uniformity and predictability (for example, see Genesis 8:22).
Skeptic: That is simply a bad explanation. Science is and always has been the right way to figure out the universe.
Believer: When you talk about good and bad and the right and wrong way to do something, you are presupposing universal and objective moral absolutes that determine good and bad, and right and wrong. Moral sensibilities can’t be accounted for on any belief system that excludes a moral law giver. All that can be said is that rightness is justified on the virtue of rightness. (or “Be good because it’s good to be good.”) The God of the Bible is a moral Being, and “good” is a part of His very nature. His moral law is written on the hearts of His creation (Romans 2:15), and He offers a solution for our falling short of the requirements of the law in the atoning sacrifice of His Son Jesus Christ.
