In my Apologetics and Evangelism class, there was a very interesting quote I thought I would share. It is against the claim that Presuppositional Apologetics is circular in its reasoning. What do you think?
“To deny circularity when it comes to an ultimate authority is to subject oneself to an infinite regress of reasons. If a person holds to a certain view, A, then when A is challenged he appeals to reasons B and C. But, of course, B and C will certainly be challenged as to why they should be accepted, and then the person would have to offer D, E, F, and G, as arguments for B and C. And the process goes on and on. Obviously it has to stop somewhere because an infinite regress of arguments cannot demonstrate the truth of one’s conclusions. Thus, every worldview (and every argument) must have an ultimate, unquestioned, self-authenticating starting point. Another example: Imagine someone asking you whether the meter stick in your house was actually a meter long. How would you demonstrate such a thing? You could take it to your next-door neighbor and compare it to his meter stick and say, “see, it’s a meter.” However, the next question is obvious, “How do we know your neighbor’s meter stick is really a meter?” This process would go on infinitely unless there were an ultimate meter stick (which, if I am not mistaken, actually existed at one time and was measured by two fine lines marked on a bar of platinum-iridium allow). It is this ultimate meter stick that defines a meter. When asked how one knows whether the ultimate meter stick is a meter, the answer is obviously circular: The ultimate meter stick is a meter because it is a meter. This same thing is true for Scripture. The Bible does not just happen to be true (the meter stick in your house), rather it is the very criterion for truth (the ultimate meter stick) and therefore the final stopping point in intellectual justification” (Michael J. Kruger, “The Sufficiency of Scripture in Apologetics,” in The Master’s Seminary Journal, 12/1 (Spring 2001) 81, n. 31).
