Three Pragmatic Arguments for Theism

"You have made us for Yourself, and our hearts are restless until they rest in You." - Saint Augustine, Confessions 1.1.1.

Introduction

Pragmatic arguments for theism are often given rather short shrift, treated as mere rationalizations and wishful thinking. I find this rather puzzling; after all, if one is trying to decide what to believe, it seems perfectly rational to incorporate considerations about the effect that one's decision will have on the rest of one's life. With that said, I'd like to consider three underappreciated arguments for theistic belief.

Forgiveness and the Moral Life

The first argument is from the nature of human moral psychology. When we have done wrong, we tend to crave forgiveness; indeed, a human being who did not desire forgiveness following serious wrongdoing would be regarded as psychologically defective. But note that if God does not exist, then many acts of human wrongdoing are literally unforgivable, in the sense that nobody could possibly have standing to forgive them. After discussing the case of those who took part in crimes against humanity, Peter Hacker writes:

It seems evident in these cases that no human being could possibly have the right to forgive them. Though they are not more evil than someone who tortured a single child to death, the magnitude of the evil they have done is monstrous. No one could possibly stand in a special relationship to the vast number of dead that would give them the locus standi to forgive such monsters as Enver and Talaat, Hitler and his henchmen, Stalin, Mao, Pol Pot, and so forth. The survivors of such holocausts may be able to forgive their persecutors, but it is not evident that they ought to. But be that as it may, they can forgive only for themselves – they cannot forgive in the name of the thousands, hundreds of thousands, or millions of dead. Indeed, it lies so far beyond the bounds of intelligibility that it is altogether opaque what would count as forgiving the perpetrators, as opposed to asking for mercy for them. (2021, 148-149)

It is not only genocidaires who face such a predicament; even more ordinary offenders may find themselves in a similar state. For example, suppose that Thomas' grandmother is suffering from Alzheimer's, as a result of which she is rather hard to be around. He neglects to visit her, thereby failing in his familial obligations. After her death, Thomas comes to regret his behavior, and wishes to seek forgiveness. But who can offer it to him? His grandmother is dead, and no other human being has standing to offer absolution. So he is stuck in his guilt, unable to be forgiven.

Of course, if God exists, then there is a potential source of forgiveness. Traditional theistic religions assert that God is the primary aggrieved party in every case of human sin. What is more, since he stands in a particular unique relationship to all creatures (i.e. that of being their creator), he plausibly has standing to forgive offenses committed against them. He is also believed to be omnibenevolent and perfectly loving, ready and willing to offer absolution to whoever might want it. 

The upshot of all of this is that without God, the human moral life is ultimately, to some extent, absurd. Only belief in God can allow us to make sense of our own need for forgiveness, and thus, insofar as one thinks that human life is ultimately comprehensible, one has reason to affirm the truth of theism.

One can also present the argument in terms of our obligation to seek forgiveness. Alexander Pruss presents a version of the argument which goes as follows:

1. If one has done a wrong, one ought to ask someone for forgiveness of it.
2. If God does not exist, there are some wrongs (e.g., the murder of someone who has no friends or relatives) that one cannot appropriately ask anyone for forgiveness of.
3. If one ought to do something, then one can appropriately do it.
4. Therefore, if God does not exist, there are some things one ought to do but cannot appropriately do. (By 1 and 2)
5. Therefore, God exists. (By 3 and 4)

Personally, I prefer to formulate the argument in terms of our own deeply-felt need for absolution in the wake of sin. That said, I find Pruss' formulation to be interesting as well.

The Desire for Life

The second argument is from the rationality of the desire for continued life. It is obvious that human beings (when they are sane and healthy) typically desire the continuation of their lives, and that they are entirely right to do so. A human being who did not have this desire would be regarded as psychologically ill, unless they were in very special circumstances (consider the case of St. Ignatius, who sought a martyr's death at the hands of pagan Rome).

The difficulty is that if God does not exist, then it is hard to explain how our desire for life could be rational. For plausibly this desire can be rational only if it is reflective, where "my desire to engage in some activity A is reflective only if there are strong reasons to believe that A is a worthwhile activity" (De Ray 2023, 685). But why should we believe that our continuing to live is worthwhile? After all, "for every instance of good in any given life (happiness, desire satisfaction, success), there is a corresponding instance of evil (sadness, desire-frustration, failure), and it is practically impossible to show (to oneself or to others) that the former outweigh the latter" (ibid., 687).

So it seems that the atheist is stuck with a substantial difficulty: they do desire to live, and it is evident that this desire is rational; however, they are unable to account for how this desire could be rational. The theist, on the other hand, has an easy response: they believe that the universe is providentially ordered by a perfectly loving creator, who would be both willing and able to ensure that the lives of rational creatures are worthwhile. 

Christophe de Ray (2023, 683) summarizes the aforementioned argument like so:

1. The desire for life is rational.
2. The desire for life is irrational, unless it is reflective.
3. If naturalism is true, the desire for life cannot be reflective.
4. Therefore, if naturalism is true, the desire for life is irrational.
5. Therefore, naturalism is false.

The upshot is that our own desire for continued life is only comprehensible if theism (or something very much like it, such as some form of axiarchism) is true.

Pascal's Wager

The third argument is among the most unfairly maligned in all of philosophy. I speak of course of Pascal's Wager, which the man himself presents as follows:

“God is, or He is not.” But to which side shall we incline? Reason can decide nothing here. There is an infinite chaos which separated us. A game is being played at the extremity of this infinite distance where heads or tails will turn up... Which will you choose then? Let us see. Since you must choose, let us see which interests you least. You have two things to lose, the true and the good; and two things to stake, your reason and your will, your knowledge and your happiness; and your nature has two things to shun, error and misery. Your reason is no more shocked in choosing one rather than the other, since you must of necessity choose... But your happiness? Let us weigh the gain and the loss in wagering that God is… If you gain, you gain all; if you lose, you lose nothing. Wager, then, without hesitation that He is.

While for many years the philosophical consensus was that Pascal's Wager is "almost entirely worthless" (Oppy 1991, 159), more recent writers have breathed new life into the argument. In particular, Elizabeth Jackson has done an enormous amount of valuable work on the topic (see e.g. her 2016, 2023a, 2023b, 2023c, forthcoming). A very useful defense of Pascal's Wager is provided by Jackson and Rogers (2019), who provide a plausible way to do decision theory involving infinite utilities, which renders the Wager a perfectly kosher piece of decision-theoretic reasoning.

The upshot is that one ought to endeavor to believe in and practice the religion to which one assigns the highest credence, which will in most cases mean accepting a belief in God.

Conclusion

I believe that the three arguments discussed above are highly cogent, and deserving of a great deal more attention than is commonly paid to them. I hope that the reader will examine the existing literature on these arguments (some of which I have linked to above), and will ponder them deeply.

Happy New Year to all who read this, and God bless you and yours.
