I am going to respond to this comment by Justin Edwards – http://airocross.com/2014/02/07/dear-presuppositionalist/#comment-9130 His words are in italics.
Hi Neil, thanks for the comment. I don’t think the issue is never using evidences, but never using evidences to prove God to an unbeliever, as Romans 1 already affirms their knowledge of Him.
Justin is not clear on what he means by “prove.” He is not clear what he means by “knowledge.” Romans 1 may refer to potential or actual knowledge of God. These qualms I will set aside. Unfortunately, Justin rests his entire case on evidences later on in his comment, citing evidence from textual criticism as reason to deny Islam. I will set this observation aside as well and focus instead on a recurring problem amongst “presuppositionalists.”
Perhaps you have seen this before, but I have found it to be helpful (unsure of author):
Unbeliever: Why can’t some other “god” be the necessary staring point?
Christian: Cause there are no other gods.
Presumably, the Christian has already made a case for God through the so-called “TAG.” Now, the unbeliever asks a perfectly reasonable question pertaining to TAG. That is, why this particular God and not another? Unfortunately, Justin does not offer a valid answer for the unbeliever. He simply assumes there are no other gods. The basis for his assumption is the existence of God. Yet it’s the existence of God that the unbeliever is questioning. So Justin’s response lands him in a vicious circle.
U: How do you know that?
C: Cause God tells us: “For all the gods of the nations are idols, but the
Lord made the Heavens” Psalm 96:5
Here’s the trouble. The Christian is making a case for the existence of God. The Christian says God is “the necessary starting point.” When the unbeliever asks why another god cannot be the necessary starting point, the Christian merely asserts that God says otherwise. However, the existence of God is what is in question. In answering the unbeliever, the Christian assumes the very thing he has set out to “prove,” that is, the existence of God. This is a simple case of begging the question.
U: What about the gods of the other religions.
C: They don’t exist.
Again, Justin is free to assert that the gods of other religions don’t exist, but he has not shown it. He is resting his case on the existence of God, when that is what he is hoping to show. This sort of reasoning is not clever or cute, it’s just bad.
U: But other people believe that other gods exist.
C: I would argue that they don’t, as Scripture teaches us that they are
“suppressing the truth in unrighteousness.”
I wish he would argue! Instead, he continues to make assertions based upon the existence of God which he has yet to prove.
U: Could you demonstrate why Allah or Vishnu couldn’t be the necessary
C: Sure, cause God tells us they don’t exist.
Again, this is not a “demonstration” at all. Rather, it is an assertion. It is an assertion without any backing, other than the assumption of the existence of God. It’s fine and dandy to assume and assert the existence of God, of course, but don’t offer mere assumption and assertion in lieu of an argument and then call that apologetics. That’s not helpful to the Christian cause, and it’s certainly not persuasive.
U: But their “holy” books would argue that your God doesn’t exist, how would
you deal with them?
Christian: Which one do you believe?
The way the Christian is about to “deal with them” is by not dealing with them at all.
U: None of them.
C: Then there is no sense arguing about them. We could also sit here and
argue whether or not the moon is made of green cheese, but since neither of
us believe that it would be a waste of time.
Actually, there is plenty of sense arguing about them, but the gung-ho presupper of doom is too naïve to spot why. Let’s take it from the top. The Christian has no doubt offered some claim about God being “the necessary starting point.” Necessary. Now, necessary means no other “starting point” is even possible. When the Christian makes that sort of claim concerning necessity, he bears the burden of proof in refuting all possible contenders. That means actually dealing with other “holy” books. The unbeliever is not being the nitwit here. He is requesting the Christian to make good on his earlier claim. Unfortunately, the Christian has written a check he cannot cash. The unbeliever is politely calling his bluff, and the Christian is dodging the question.
U: Surely you have heard of positing hypotheticals to disprove a claim?
C: Yes, that would make sense in other instances but we are talking about
the necessary starting point to make sense of argumentation, so it would not
make sense argue from a position that you don’t believe.
Positing hypotheticals would make sense in this instance as well. The reason the Christian offers as to why positing hypotheticals would not make sense in this instance is no reason at all. Yes, we are supposedly talking about “the necessary starting point to make sense of argumentation.” The Christian has asserted (repeatedly) that this starting point is God. It follows that the onus is on the Christian to support his claim. What does not follow is what the Christian is saying here. Take another look at how bad the reasoning process is in the following:
Positing hypotheticals to disprove a claim makes sense in some instances.
In this instance we are talking about the necessary starting point to make sense of argumentation.
Therefore, it does not make sense to posit hypotheticals in this instance.
Huh? Why not? How does that conclusion follow from the premises at all? It doesn’t. Let’s remember that the Christian has stated God is the necessary starting point to make sense of argumentation. The unbeliever has posited hypotheticals (which in this instance are also actuals) in order to see the Christian make good on his claim. Again, the claim in question, the claim to necessity, merits the request to see the refutation of all possible contenders. It does not follow that the unbeliever needs to explicitly hold any one of them. It also does not follow from the fact that the unbeliever does not explicitly hold to any one of them that the unbeliever cannot offer them as counters to the Christian’s extremely strong claim.
U: Ah, you are just saying that because you can’t refute my hypothetical
that Allah is the necessary staring point.
C: Not at all. Just for kicks, I will refute your hypothetical
Premise 1: If atheism is true, no gods exist
Premise 2: Atheism is true.
Conclusion: Therefore no gods exist and you have been refuted.
This sort of red herring is unhelpful to the apologetic endeavor. Let’s remember that the Christian is obligated to refute Islam as the necessary starting point for argumentation, given his claim that God is the necessary starting point for argumentation. The syllogism above merely assumes that atheism is true. No argument is made to that end. Further, as should be obvious, the truth of atheism is inconsistent with the truth of Christianity, and truth is, presumably (at least on some interpretations), a necessary characteristic of a transcendental. The intentions of the Christian are questionable at this point in the dialogue.
U: Um, but you are not an atheist!
C: Um, but you are not a Muslim! Do you see why refuting hypotheticals when
it comes to the justification for knowledge is pointless?
No. In fact, the syllogism above does not even pertain to someone’s adherence to atheism, Islam, etc., but whether or not atheism is true, which is an entirely different matter. The Christian in this hypothetical dialogue is either extremely confused or extremely dishonest. Again, refuting hypotheticals (which, again, are not merely hypotheticals) is necessary to defend the claim to necessity. The unbeliever is not being dishonest here. The same might not be said for the Christian.
If the things Justin wrote about in the main post on which he comments are true, and I suspect they are, then “presuppositionalists” must be equally careful to be loving in the content of their presentations. That means actually arguing their case, rather than making assertion after assertion about it and dismissing every counterpoint raised by the unbeliever. Are these presuppositionalists not out to persuade the unbeliever? (Perhaps not!)
