Apologetics

The ILIAD Forum

/ Apologetics, Philosophy, Theology

Readers of this blog may be interested to know about a new online resource, the ILIAD Forum. (‘ILIAD’ stands for Ivy League Informational Apologetics Database.) According to the website:

The Iliad Forum was founded in 2021 by undergraduate students from all across the Ivy League, who wanted to provide an online, accessible, and rigorous database of answers to common questions about the nature and commitments of orthodox Christianity. The Iliad Forum site is intended to be a resource for both Christians and non-Christians, where answers to deep and complex questions and objections can be found almost immediately. Many of the questions that we deal with are tailored to the specific interests of undergraduate students at Ivy League universities. However, we also deal with broader topics, such as Christianity in the job market, philosophical apologetics, and Biblical history.

The website already contains dozens of short articles in answer to a wide range of questions. The articles are written by scholars with expertise in the relevant area, including Vern Poythress, William Edgar, and Scott Oliphint.

I was invited to submit answers to five questions in the area of philosophical theology and apologetics. I gather the articles will be posted on the website at intervals, so I’ll post the links here as they become available.

On Malpass’s Dilemma

/ Apologetics, Philosophy / 2 Comments

Alex Malpass has offered one of the most thoughtful critiques of the argument for God from logic in his 2020 Sophia article, “Problems for the Argument from Logic: a Response to the Lord of Non-Contradiction.” Here’s the abstract:

James Anderson and Greg Welty have resurrected an argument for God’s existence (Anderson and Welty 2011), which we will call the argument from logic. We present three lines of response against the argument, involving the notion of necessity involved, the notion of intentionality involved, and then we pose a dilemma for divine conceptualism. We conclude that the argument faces substantial problems.

In this post I will share some thoughts on the third of these “three lines of response,” which I take to be the most interesting point of criticism.1 (Note: I’m speaking only for myself in this post; Greg can speak for himself!)

The argument for God from logic involves defending a version of divine conceptualism (or better, “theistic conceptual realism,” to use Welty’s terminology) according to which the laws of logic, as necessarily true propositions, are ultimately just divine thoughts. Strictly speaking, the argument can be run from any necessary truths, not just the laws of logic, but the laws of logic serve as familiar and convenient examples of necessary truths.2

Horns of a DilemmaIn the last major section of his article, Malpass presents a “dilemma for divine conceptualism.” Rather than quote him at length, I will try to summarize the thrust of his challenge. He begins by observing that parts of our argument appeal to a distinction between “thoughts and the content of those thoughts” (see, e.g., footnote 31 of our 2011 article). But then he points out that this seems to raise a problem for the claim that propositions are divine thoughts. In the first place, he argues, “a thought cannot be the content of itself” (p. 251). The idea that a thought can be its own content is either flat-out incoherent or leads to a “vicious infinite regress” (p. 252). To avoid this, the divine conceptualist has only two options:

  1. A divine thought has no content.
  2. A divine thought has content distinct from the thought itself.

Option 1 looks like a non-starter. If divine thoughts have no content, they can’t be about anything. Isn’t it obvious that God’s thought that 2+2=4 is contentful? Doesn’t it have some content that distinguishes it from other thoughts (e.g., God’s thought that Socrates is mortal)?

Option 2, however, doesn’t look any more promising. Recall our contention that the laws of logic, as necessarily true propositions, are a special category of divine thoughts. Let LL be some proposition that expresses a law of logic (e.g., the law of non-contradiction). LL is ultimately just a divine thought, so we argue. But according to option 2, the content of LL is something other than LL itself. So what could it be? Presumably that content would have to be propositional or intentional in nature. But it couldn’t be a proposition other than LL, for two reasons. First, that would mean LL has the wrong content; the divine thought would be about something other than what it’s supposed to be about. To use Malpass’s example, LL couldn’t have the Pythagorean theorem as its content; it’s supposed to be about the law of non-contradiction, not a geometrical theorem. The second reason is that if the content of LL is a proposition, but not LL itself, then it must be some other proposition, and therefore (given divine conceptualism) some other divine thought. Call that other divine thought LL*. But then the same considerations will apply to the content of LL*, in which case we’re on the road to a never-ending regress of divine thoughts containing divine thoughts, their content being endlessly deferred.

  1. This criticism also came up in our conversation last September hosted by Parker Settecase. ↩
  2. As we note in our paper, someone might take the laws of logic to be something other than propositions (e.g., relations), but in that case we can simply restate the argument in terms of necessarily true propositions about the laws of logic. ↩

A Conversation with Alex Malpass

/ Apologetics, Philosophy

Last week I had the pleasure of interacting with British philosopher Dr. Alex Malpass on the topic of the argument for God from logic. (Many thanks to podcaster extraordinaire Parker Settecase for hosting and moderating the discussion.) Dr. Malpass recently published an article in the journal Sophia in which he leveled several objections at the Anderson-Welty argument. Here’s the abstract for the article:

James Anderson and Greg Welty have resurrected an argument for God’s existence (Anderson and Welty 2011), which we will call the argument from logic. We present three lines of response against the argument, involving the notion of necessity involved, the notion of intentionality involved, and then we pose a dilemma for divine conceptualism. We conclude that the argument faces substantial problems.

In our 90-minute-or-so live-broadcast discussion, Dr. Malpass summarized his three criticisms and I gave responses to each one. We also fielded a few questions from viewers. In the end, there was a surprising (but gratifying) amount of agreement between us regarding some of the logical and metaphysical issues at stake, even though Alex remains unpersuaded by the argument! Anyway, you can watch the exchange and draw your own conclusions:

Be sure to watch right to the end, where the two Brits are invited to weigh in on the contentious coffee-versus-tea debate.

I’m grateful to Dr. Malpass for his willingness to participate in what proved to be an illuminating and good-humored discussion, and I look forward to further exchanges (including, I hope, a published response to his article). For those interested, Dr. Malpass has his own blog here.

Reforming Apologetics (Wrap-Up)

/ Apologetics / 4 Comments

For completeness, here are all the entries in my series reviewing J. V. Fesko’s Reforming Apologetics:

If you’re pressed for time (and aren’t we all?) you can get the gist of things by reading the entries on “Introduction,” “The Light of Nature,” and “The Book of Nature and Apologetics.” If you’re especially interested in Dr. Fesko’s critiques of the Van Tilian emphasis on ‘worldview’ and Van Til’s advocacy of transcendental argumentation, along with my responses to those critiques, read the entries on chapter 5 and chapter 6.

Reforming ApologeticsMy overall assessment of the book can be summarized as follows: I think Dr. Fesko does a great job of defending the use of natural revelation (“the book of nature”) in apologetics and in showing how the mainstream Reformed tradition has consistently and enthusiastically affirmed such use (albeit with important qualifications related to the noetic effects of sin and the necessary interpretive role of special revelation). However, the major shortcomings of the book are its repeated misinterpretation and mischaracterization of Van Til’s position (and that of other presuppositionalists, such as John Frame and Scott Oliphint) and its failure to establish its thesis that Van Til’s views are significantly at odds with Calvin’s views or with confessional Reformed theology. In fact, given what Dr. Fesko affirms in chapter 8 about a “covenantal epistemology,” and his agreement with Calvin (and Van Til!) on the need to read “the book of nature” through the “corrective lenses of Scripture,” I believe he ought to be more hesitant about aligning himself with the Thomistic (“classical”) approach to natural theology and more sympathetic toward Van Til’s efforts to “reform apologetics” by bringing it more into line with a consistently Reformed epistemology and doctrine of revelation. In any event, it’s good that Reformed brethren are continuing to have these conversations. Let’s be thankful for the significant areas of common ground we affirm, while pursuing better understanding of one another and (by God’s grace) greater convergence over time.

Reforming Apologetics (The Book of Nature and Apologetics)

/ Apologetics / 6 Comments

Previous posts:

Summary of Chapter 8

In the final chapter of his book, J. V. Fesko seeks to “present a basic sketch of how the books of nature and Scripture can work in concert in apologetics” and “demonstrate how Christians can stand on the authority of Scripture to present the claims of Christianity while at the same time using and appealing to the book of nature” (pp. 193-94). He proposes to do this in five stages:

  • The first section addresses epistemological starting points, placing epistemology “within the framework of classic covenant theology” and arguing that a “covenant epistemology” has a twofold goal: (1) loving God and (2) the eschatological transformation of the knower. The question of the epistemological consequences of the fall is also discussed.
  • The second concerns the goals of apologetics. What role should intellectual arguments play in one’s apologetic system?
  • The third discusses “the various points of contact that believers and unbelievers share” (p. 194). The redemptive-historical distinction between Christ as Logos and Christ as Mediator will prove important here.
  • The fourth explains “the importance and necessity of employing evidence in the defense of Christianity” (p. 194).
  • The fifth section focuses on “the importance of humility in defending Christianity” over against the exaggerated claims of “some within the Reformed community in the twentieth century” (p. 194).

Materialism and Mysteries

/ Apologetics, Philosophy, Theology / 1 Comment

Bart EhrmanA friend brought this recent blog post by New Testament scholar Bart Ehrman to my attention. Since it intersects with several areas of interest to me, I thought it would be fun to write some commentary on it.

Dr. Ehrman makes four basic points in his post:

  1. He is a metaphysical materialist. He believes that everything that exists is material in nature.
  2. Materialism faces some “enormous conceptual problems.”
  3. Even so, that’s no reason for him to abandon materialism, because every belief-system has its mysteries. Every belief-system has conceptual problems that seem to defy explanation, but it doesn’t follow that it’s unreasonable to hold on to that belief-system.
  4. Moreover, while every belief-system has its mysteries, it can still be the case that some belief-systems are more reasonable than others.

Let’s consider each point in turn.

1. Materialism

After some throat-clearing about not trying to “impose” one’s views on others, Dr. Ehrman writes:

Anyway, as probably fewer members know, I have been more-or-less a complete materialist for about twenty years. I do not believe there is such a thing as a non-material, supernatural realm. There’s the material realm, and that’s it, all the way down.

I used to think that we are (I am) made up of two things: a body and a mind/soul/spirit/whatever you want to call it. I don’t think that anymore.

But for now, I think I am made up of one thing. Matter. I’ve got (by my count) one body, eleven organ systems, 79 organs, roughly 37 trillion (count them!) cells, and god knows how many molecules. And nothing else. If some of those cells die – well they die all the time. If enough of them die in one place at one time, it could be a problem. If one of the organs goes kaput, it could be a very big problem. If one of the vital organs goes, as we used to say in high school, it’s cookies.

So Ehrman is clearly rejecting any version of dualism in favor of a clear-eyed, straight-talking, unabashed materialism. Everything that exists is entirely material in nature, including you and me. There is no soul distinct from the body. There is no mind distinct from the brain.

As I’ll explain shortly, I think this materialist position is demonstrably false, but I have to give Ehrman credit for being so direct and explicit about his position. No mincing words here! No side-stepping or fencing-sitting. I’ve encountered many unbelievers who are eager to criticize other people’s views without ever committing to any specific position themselves. They’re very eager to declare what they don’t believe (and why they don’t believe it) but very reluctant to tell us what they do believe (and why they believe it).

Bart Ehrman is not one of those unbelievers. Kudos to him for nailing his materialist colors firmly to the mast!

Reforming Apologetics (Dualisms)

/ Apologetics

Previous posts:

Summary of Chapter 7

The purpose of chapter 7 of Reforming Apologetics is to defend natural theology (in the Reformed Thomist tradition) from the charge that it succumbs to “dualistic thinking.” The central target is the Dutch neo-Calvinist thinker Herman Dooyeweerd, although Cornelius Van Til plays a supporting role as another critic who complains about a dualism that afflicts Roman Catholic theology and infects some streams of Reformed theology.

In fact, Dr. Fesko introduces the chapter’s theme by citing Van Til’s accusation that “the Roman Catholic nature-grace dualism compromises both the theological and the apologetic integrity of the scriptural teaching about epistemology” (p. 161). According to Van Til, this “nature-grace dualism is unscriptural, since it leaves a beachhead of autonomous reason, which makes fallen human beings the arbiters of truth” (p. 162). Indeed, Van Til thinks there is a deeper problem:

Van Til contends that Roman Catholic theology falls short of scriptural teaching because it rests on an Aristotelian starting point, a dualistic understanding of man. Hence, Christians must purge dualistic thought from their theology and begin from a pure scriptural starting point. (p. 162)

Similar criticisms come from Cornelius’s nephew, Henry Van Til, in his book The Calvinistic Concept of Culture, and from other “neo-Calvinist theologians and philosophers” such as James K. A. Smith, Albert Wolters, Cornelius Plantinga, Jr., Brian Walsh, and Richard Middleton. Dr. Fesko traces these criticisms to the influence of Abraham Kuyper, who argued that “since no area of life lies beyond the rule of Christ, all dualistic thought must be excised” (p. 163).

What does this have to do with Reformed apologetics? Fesko explains:

The dualism critique, therefore, plays an important role in debates over apologetic methodology and is one more hurdle to clear in order to recover the book of nature. (p. 163)

Fesko acknowledges that there are different versions of the “dualism critique,” but his aim in this chapter is to argue that the critique “rests on an inaccurate evaluation of the historical evidence.” Indeed, attempts to expose unbiblical dualisms in the natural theology tradition are guilty of a “fourfold failure”:

[T]hey separate what theologians merely distinguish, have little or no historical evidence to support them, ultimately rest on questionable philosophical claims rather than biblical exegesis, and employ the debunked hellenization thesis of Adolf von Harnack (1851-1930). (p. 164)

The chapter makes its case, first, by surveying three different types of dualism, and second, by analyzing and rebutting the charges of dualism leveled at Aquinas and some Reformed theologians.
