Witmer continues by giving us an example of two types of meanings behind “justify” (note to Roman Catholics, I’m not using the theological term here) and “account.” He says:

If I ask you for a basis for your belief that (for example) 15+16=31, one thing I might be asking for is a justification or argument for that belief. Why believe it’s true? In response to this I might present to you the process by which I calculated the sum. The other thing I might be asking for is an explanation of its truth: why is it true? In response to this I might say that numbers have their relational properties essentially, perhaps; this question is harder to answer in the case in question.

(Ibid, 7)

This can, indeed, be a valid distinction to make. As such, it is important that the presuppositionalist be able to specify which meaning he intends. But granting this doesn’t solve Witmer of his problems, as we shall see.

Witmer continues:

One could have good reason to believe something is true while still finding it mysterious why it’s true. So, for instance, suppose my doctor calls me up one day and tells me, “Listen, I’m in a rush and I can’t explain, but your student So-and-so is going to have a fit this afternoon, probably during your class, and when this happens you need to react immediately and call the paramedics.” And then he hangs up. Now I have a good reason to believe this student will have a fit, but I have no idea why he will have a fit.

(Ibid, 7)

In this case, we see that Witmer has surrendered personal thought for an argument from authority. He assumes that the doctor knows what he is speaking about, and therefore Witmer trusts that what the doctor claims will come to pass.

There is nothing wrong with this approach in general. It is certainly impossible for any person in one lifetime to become an expert on everything! Therefore, we are forced to move to arguments on authority at some point.

However, what cannot be denied is that an argument from authority is a faith-based argument. In the above, Witmer does not actually have good reason to assume that something would actually happen to one of his students because he, presumably, isn’t a medical technician. Instead, he says he has a good reason to trust the doctor who has made the claims. But Witmer’s trust of the doctor does not make the claims of the doctor more sure. The doctor’s claims either are or are not valid, regardless of what Witmer believes about the doctor.

Thus, Witmer’s argument is really that he has a good reason to trust the doctor. Again, there is nothing wrong with this approach as long as one accepts that it is an argument from authority that gives Witmer the ability to “know” something without knowing why.

Let us continue:

One could also have a good explanation for something’s being true without having any good reason to believe it is true in the first place. So, for instance, suppose that I speculate that someone I know (but haven’t seen in years) has just been murdered by her husband; I have no reason to believe this, it’s just an idle speculation. Even so, I might be able to suggest a good explanation for it. If she’s been murdered, one thing that could explain this is her husband’s tendency to alcoholism and extreme jealousy.

(Ibid, 8)

I don’t see how this could be considered a “good” explanation. It’s a hypothetical explanation, yes; but “good”?

Continuing:

Notice that our discussion earlier of beliefs that we take for granted indicates that some beliefs might be reasonable without argument. So if my belief that my senses are mostly trustworthy is to be taken for granted, then, if someone insists on a basis for this, I can of course say, “there is no basis; this is one of the things I take for granted.”

(Ibid, 8)

Again, this shows that Witmer does not understand truly presuppositional positions. (Likewise, based on Daniel Morgan’s comments to my previous blog entry in this series, Daniel doesn’t understand this part either.)

Just because someone says “X is my presupposition” does not mean X actually is his presupposition! (If presuppositionalism was that easy, everything could be claimed a presupposition!) One’s statement that something is foundational does not make it truly foundational. One must actually establish that a claim truly is presuppositional. Here’s a major hint: if your “presupposition” requires other presuppositions in order to be true, you’re not at your presuppositions yet.

True, Witmer could argue that I am forcing my definition of presupposition on him; but Witmer is the one who chose to write in the English language. And the terms we use have definitions. If he seeks to abandon those definitions, then he is operating from a completely different presupposition than anything he’s written so far anyway.

Moving back, when Witmer claims that he can presuppose the trustworthiness of his senses without any basis at all, we are not yet at a presuppositional position. In order to be able to take our senses as valid for granted, one must first presuppose that our senses are accurate and that they provide a totality of information about our universe (two ideas that are subjected to much criticism already). In other words, there are presuppositional requirements to saying that our senses can be taken for granted, and that is a presuppositional idea of the nature of the universe!

In order to take our senses for granted, we must presuppose that there is no supernatural world. We must presuppose empiricism. We must presuppose that there cannot be anything outside of the range of our senses that could actually impact reality. All these things precede the concept that our senses are trustworthy, and therefore Witmer’s objections are groundless.

Continuing:

(Again, there’s a good question as to why some things should be taken for granted and others can’t; that’s a deep question that I don’t want to try to tackle here.)

(Ibid, 8)

And yet it is the backbone of his argument at this point. If his argument is to be considered by rational people, Witmer must explain this very point!

Witmer continues:

In the same way there are truths that don’t have any deeper explanation. So, perhaps the right answer to “why is it that 15+16=31?” is just “That’s just the way it is; there’s no further explanation.”

(Ibid, 8)

Except that I, for one, can already see something more basic than 15+16=31 at root. It is correct because of the Law of Identity. 1 = 1. We define the number 2 as 1 + 1, etc. We could just as simply define ^ as 1 + 1; the symbol doesn’t matter. What matters is the identity of the defining unit, in this case 1. Therefore, 15+16 is simply another manner of writing 1 + 1 + 1 + 1 + … It is a matter of identity and definition.

Now Witmer could certainly argue about the concept of “identity” and “definition” and say that those are things that “just are” instead. At least that would get us closer to a basic starting point.

Witmer continues:

Just as it’s hard to see how one could avoid taking some beliefs for granted, it’s hard to see how one could avoid allowing that some facts are just primitive or unexplained in this fashion.

(Ibid, 8)

Of course; but what is at issue isn’t the fact of primitive, unexplained facts. What’s at issue is which facts actually are primitive and unexplainable.Witmer concludes this section by stating:

I stress this because it is in fact always open to you, if you are defending yourself against this negative strategy whereby they aim to show that all belief systems contrary to theirs are self-undermining or incoherent, you can take advantage of this option. If they say, “But what is your basis for logic?” (and if they mean “what explains why these things are true?”), you can always say, “They just are, and that’s the end of the story. They can hardly complain that this move is never allowed, as they need to make it themselves, albeit with a different (alleged) truth.

(Ibid, 8)

Again, this shows that Witmer does not understand truly presuppositional positions. Again, something is not a presupposition just because it is claimed to be foundational. It must be foundational first.

Therefore, Witmer’s claims that theists “can hardly complain that this move is never allowed” is false. It is only “allowed” at the presuppositional level, not at something built two hundred stories above the foundation!
