Presuppositional apologetics

Presuppositional apologetics is a school of Christian apologetics, a field of Christian theology that attempts to present a rational basis for the Christian faith, defend the faith against objections, and attack the alleged flaws of other worldviews. Presuppositional apologetics argues that the existence or non-existence of God is the basic presupposition of all human thought, and that all men arrive at a worldview which is ultimately determined by the theology they presuppose. Evidence and arguments are only marshalled after the fact in an attempt to justify the theological assumptions already made. According to this view, it is impossible to demonstrate the existence of God unless one presupposes that God exists; modern science is incapable of discovering the supernatural because it relies on methodological naturalism and thereby fashions a Procrustean bed which rejects any observation which would disprove the naturalistic assumption. For example, science's methodological naturalism cannot make use of this statement:

By faith we understand that the universe was created by the word of God, so that what is seen was not made out of things that are visible. —Hebrews 11:3 ESB

Presuppositional apologetics

Presuppositional apologetics is a school of Christian apologetics, a field of Christian theology that attempts to present a rational basis for the Christian faith, defend the faith against objections, and attack the alleged flaws of other worldviews. Presuppositional apologetics is especially concerned with the third aspect of this discipline, though it generally sees the trifold distinction as a difference in emphasis rather than as delineating three separate endeavors. Presuppositional apologetics developed in and is most commonly advocated within Reformed circles of Christianity.

The key discriminator of this school is that it maintains that the Christian apologist must assume the truth of the supernatural revelation contained in the Bible (that is, the Christian worldview) because there can be no set of neutral assumptions from which to reason with a non-Christian. In other words, presuppositionalists say that a Christian cannot consistently declare his belief in the necessary existence of the God of the Bible and simultaneously argue on the basis of a different set of assumptions (presumably those of the non-Christian) in which God may or may not exist.

Comparison with other schools of apologetics

Presuppositionalists contrast their approach with the other schools of Christian apologetics by describing them as assuming that the world is intelligible apart from belief in the existence of God and then arguing on purportedly neutral grounds to support trusting the Christian Scriptures and the existence of God. Thomas Aquinas himself insists that many crucial truths can only be known through scripture, and none of his arguments are intended to show the entire Christian picture. Specifically, presuppositionalists describe Thomistic (also "Traditional" or "Classical") apologetics as concentrating on the first aspect of apologetics with its logical proofs for the existence of God, simply assuming common ground with the non-Christian and utilizing a piece-by-piece methodology. In this scheme, the common foundation of neutral brute facts leads to a generic concept of deity, then to the various characteristics of the Christian God as revealed in Scripture, and so forth. Piece-by-piece, Christian theology is built up from a neutral common ground.
