Greg Welty on Alvin Plantinga

Greg Welty’s book Alvin Plantinga hits the bookstore shelves today. I’m sure you’re dying to hear what I think about it, so here’s my endorsement:

Alvin Plantinga by Greg WeltyAlvin Plantinga is one of the titans of contemporary Christian philosophy and it would be almost unforgivable to omit him from P&R’s Great Thinkers series. His writings over the course of a six-decade career combine an astonishing degree of creativity with rigorous analytical precision, a delightful sense of humor, and a refreshingly uncomplicated Christian piety. Until now, there has existed no reliable introduction to Plantinga’s work that I could enthusiastically recommend to students, pastors, and other interested readers. That deficiency is now remedied with the publication of Greg Welty’s Alvin Plantinga, a superlative addition to an already excellent series. As a seasoned teacher-scholar with advanced degrees in theology and philosophy and a firm commitment to confessional Reformed doctrine, Dr. Welty was the ideal person to write this book. In a concise and eminently readable style, Welty clearly explains Plantinga’s major contributions and argues that, despite Plantinga’s own deviations from the Reformed tradition at points, his most valuable contributions can be comfortably accommodated by that tradition. I would never suggest reading only one book on Plantinga, but if it must be one, make it this one.

If you want to find out a bit more about the book and its distinctive contributions, I recommend this interview with the author.

The book is available from the publisher at a significant discount right now ($10.39 instead of $15.99). So what are you waiting for? Go order a copy!

On Malpass’s Dilemma

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

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.

Greg Welty on the Problem of Evil

Why Is There Evil In The World?I posted previously about Greg Welty’s excellent book Why Is There Evil In The World (And So Much Of It)? when it was published a couple of years ago. In my (admittedly biased) opinion, it’s the best lay-level treatment of the problem of evil available today. I recommend it every chance I get.

If you want a taster, you can get it from this short article on the problem of evil, written by Greg for TGC’s Concise Theology series. It’s basically a much-distilled version of the argument Greg lays out in the book. If you like the article, you’ll appreciate the book even more!

Why Is There Evil In The World (And So Much Of It)?

I’m delighted to report that the third volume in the Christian Focus series, The Big Ten: Critical Questions Answered, is now available: Why Is There Evil In The World (And So Much Of It)? by series co-editor Greg Welty.

Why Is There Evil In The World?Having been closely involved in the editing process, I’m thrilled to see this book finally in print. The title reflects what may be the most common reason people give for rejecting the Christian faith and doubting the existence of God. It is indeed a critical question that demands an answer.

But isn’t it one Christians have been answering for centuries? Yes, of course. There are many fine works already available on this issue, both ancient and modern, and Welty acknowledges his debt to them. But I think this book fills a particular niche at this time. So many contemporary books on the problem of evil fall down in one or more of the following areas:

  • They don’t pay close attention to what the Bible actually says about the nature and origin of evil and suffering in the world, and how they fit into God’s purposes for his creation.
  • They end up taking positions that aren’t theologically orthodox (e.g., denying God’s omnipotence or omniscience).
  • They engage in philosophical speculations that aren’t tethered to (and sometimes go against) the teachings of the Bible and the creeds of the Christian church.
  • They lack clarity and precision at the very points where clarity and precision are needed. They serve up a big fat waffle-burger instead of a lean filet.
  • They’re written by authors who lack theological and philosophical training, and who aren’t conversant with the vast scholarly literature on the problem of evil.
  • They’re preaching to the choir: helpful for those who already believe, but failing to grapple with real concerns of skeptics.
  • They’re either too long-winded to keep the reader’s attention or too cursory to satisfy the reader’s concerns.
  • They’re too dry and technical for the layperson.

Why Is There Evil In The World? avoids all these pitfalls. Moreover, Greg is ideally qualified to have written this book. He wasn’t raised in a Christian home, so he knows what it’s like to be a skeptical unbeliever. He earned a bachelor’s degree in philosophy from the University of California, an MDiv degree from Westminster Seminary California, and MPhil and DPhil degrees in philosophical theology from the University of Oxford, and he has taught seminary courses in Christian apologetics and philosophy of religion for 15 years. He also serves as one of the pastors at Grace Baptist Church in Wake Forest, so he doesn’t live up in the ivory tower!

Here’s the table of contents for the book, which should give you a good idea of how Welty tackles the issue:

  • 1. What is the Problem of Evil?
  • 2. The Greater-Good Theodicy: A Threefold Argument for Three Biblical Themes
  • 3. Licensing the Greater-Good Theodicy: God’s Sovereignty over Evil
  • 4. Limiting the Greater-Good Theodicy: The Inscrutability of God’s Purposes
  • 5. Can Free Will or the Laws of Nature Solve the Problem of Evil?
  • 6. Objections
  • Appendix: Going Beyond Job, Joseph and Jesus for the Greater-Good Theodicy

The book has received endorsements from John Frame, Paul Helm, Scott Oliphint, David Robertson, and Mike Kruger, among others. So you don’t have to take it from me — it comes highly recommended! I really hope it will become the go-to book for ‘ordinary’ folk, both believers and skeptics, who are looking for a well-informed and well-argued response to this age-old question.

Six Views on God and Abstract Objects

Readers interested in the argument for God from logic will want to check out a forthcoming book: Beyond the Control of God? Six Views on the Problem of God and Abstract Objects, edited by Paul Gould, Bloomsbury Academic, 2014.

From the publisher’s website:

The question of God’s relationship to abstract objects touches on a number of perennial concerns related to the nature of God. God is typically thought to be an independent and self-sufficient being. Further, God is typically thought to be supremely sovereign such that all reality distinct from God is dependent on God’s creative and sustaining activity. However, the view that there are abstract objects seems to be a repudiation of this traditional understanding of God. Abstract objects are typically thought to exist necessarily and it is natural to think that if something exists necessarily, it does so because it is its nature to exist. Thus, abstract objects exist independently of God, which is a repudiation of the traditional understanding of God. Philosophers have called this the problem of God and abstract objects.

In this book, six contemporary solutions to the problem are set out and defended against objections. It will be valuable for all students or scholars who are interested in the concept and nature of God.

Vallicella on the Argument for God from Logic

Bill Vallicella recently posted some comments on the paper I co-authored with Greg Welty. He states that he’s very sympathetic to our project, but he finds a weak point in our argument that renders it “rationally acceptable, but not rationally compelling.” Here I respond to his concerns.

The Lord of Non-Contradiction

Philosophia Christi has kindly permitted me to post on my website a preprint of “The Lord of Non-Contradiction: An Argument for God from Logic”, which I co-authored with Greg Welty. I wrote the first version of the paper, but Greg did all the heavy lifting; the argument is indebted to the ideas he developed in his DPhil dissertation on theistic conceptual realism.

Logic

Here’s the abstract:

In this paper we offer a new argument for the existence of God. We contend that the laws of logic are metaphysically dependent on the existence of God, understood as a necessarily existent, personal, spiritual being; thus anyone who grants that there are laws of logic should also accept that there is a God. We argue that if our most natural intuitions about them are correct, and if they’re to play the role in our intellectual activities that we take them to play, then the laws of logic are best construed as necessarily existent thoughts — more specifically, as divine thoughts about divine thoughts. We conclude by highlighting some implications for both theistic arguments and antitheistic arguments.

While we don’t discuss Van Til or presuppositional apologetics in the paper, those so inclined will recognize this as a more robust exposition of a common presuppositionalist argument and they’ll also appreciate (I hope) the concluding remarks.
