Argument

Pragmatic Argument

Intro

Suppose you cannot tell, from the evidence alone, whether God exists. The case looks balanced to you. Now you still have to decide how to live. Pascal's argument is that even in that balanced state, the rational move is to live as if God exists, because of the size of the stakes.

The reasoning goes like this. If you bet on God and you are right, you gain something of enormous value. If you bet on God and you are wrong, you lose very little. If you bet against God and you are right, you gain very little. If you bet against God and you are wrong, you lose something of enormous value. Two of the four outcomes carry small consequences. Two of them carry huge consequences. And those two pull in the same direction.

Pascal never said this was a proof that God exists. It is not. It is a practical-reasoning argument aimed at the person who keeps saying "I just don't know." It says: given that you don't know, here is how a rational person decides what to do next.

The argument has serious objections, most famously the many-gods reply, which asks why Pascal's bet picks the Christian God rather than Allah, Vishnu, or some other contender. This page lays out the original wager, then handles the many-gods objection, the moral-objection ("you can't manufacture sincere belief"), and the mathematical-objection ("infinite values break the math"). The argument's job is to push the agnostic to take the question seriously, not to close the case on its own.

In full

A decision-theoretic argument: under conditions of (a) genuine uncertainty about God's existence and (b) infinite (or arbitrarily-large) stakes, expected-value reasoning favors belief. Even when the evidence for God is held to be a wash, the practical reasoning of any rational agent should land on belief, because the asymmetric payoffs make the wager rationally compelling. The argument is not (and was never) intended as a proof of God's existence; it is a practical-reasoning argument that should move the agnostic / skeptic to engage with the question of belief seriously rather than dismiss it. This page is structured as debate prep: per-premise affirmative case, anticipated objections (especially the many-gods objection), numbered rebuttals (1:1), live-cite kit, and tactical notes for live deployment.

Argument structure (Pascal's classical form)

Form

Practical reasoning under uncertainty using decision theory, specifically, dominance reasoning under asymmetric payoffs. The argument is not deductive evidential reasoning; it does not establish that God exists. It establishes only that acting as if God exists is the rational practical choice given the asymmetric stakes. The argument's natural pair is the Argument from Religious Experience (the experiential complement to the wager's choice-of-practices) and Argument from Desire (the existential complement).

Two important framings:

• Pascal's classical form: infinite stakes (eternal life vs. eternal loss), narrow contemporary application (live-options of the agent's culture).
• Jordan's modern formalization (Pascal's Wager, 2006): finite-but-arbitrarily-large stakes; works conjointly with evidential considerations narrowing the live options.

P1, Under uncertainty, choose the option with the higher expected utility

Affirmative case (second-order arguments)

1. The standard rationality of expected-utility maximization. Decision theory's foundational principle: when outcomes are uncertain and probabilities can be estimated (even informally), the rational agent maximizes expected utility, the probability-weighted average of outcome values. This is the operational principle of every well-functioning insurance market, every responsible investment portfolio, every game-theoretic strategic decision. The principle is not Pascal's invention; it is the standard form of practical reason under uncertainty.
2. Dominance reasoning is even stronger. When one option is at least as good in every state of the world and strictly better in some, the option is dominant, choosing the dominated option is irrational regardless of probabilities. Pascal's argument argues for the dominance of belief over disbelief once the asymmetric payoffs are made explicit. Dominance reasoning does not even require precise probability estimates, only that the dominated option is dominated in every state.
3. The "I won't decide" pose is itself a decision. The agnostic who refuses to wager is wagering against belief: they are living without God, structuring their life around finite goods, declining the practices that might dispose them toward belief. Time runs out (death is certain); the failure to choose belief is operationally identical to the choice of disbelief in the relevant practical respect. "You must wager" (Pascal). The forced-decision character of the situation is structural, not optional. (William James later formalizes this as the "live, forced, momentous option" condition.)
4. The principle scales appropriately to other big decisions. Compare: should you buckle your seatbelt? Probability of fatal crash on any given trip is tiny; cost of buckling is tiny; benefit of buckling in the rare crash-case is enormous (your life). The expected-utility calculation favors buckling. Pascal's argument is the same form, applied to the largest-possible-stakes decision (eternal welfare) under uncertainty about God. The principle is not occult; it is the same one we use for traffic safety, insurance, retirement planning.

Anticipated objections

1. "Decision theory doesn't apply to belief, beliefs are formed by evidence, not chosen by utility-calculation."
2. "Expected-utility calculation requires meaningful probability estimates, which we don't have for God's existence."
3. "Infinite utilities create paradoxes (Hájek), the calculation breaks down when one outcome is infinite."
4. "This is just pragmatic-justificationism, it doesn't track truth, only utility."

Rebuttals

1. Pascal's argument is precisely about the case where evidence is tied, it engages the will, not the intellect. Pascal explicitly addresses the audience for whom evidence has not closed the question: "If you cannot believe by evidence alone, here is how to engage the question with your full agency." The argument does not say "decide-by-utility-calculation what to believe"; it says "decide-by-utility-calculation what to practice, knowing that the practices dispose toward belief." The choice is for the practices (church attendance, prayer, association with believers, study of Scripture); these are voluntary actions amenable to decision-theoretic reasoning. The belief is the eventual consequence of the practices, not the direct object of choice. (Pascal's classical response to this objection in Pensées §233.) Failure mode: category-conflation between belief-formation and practice-adoption.
2. Pascal's argument works even with very weak probability estimates. The argument requires only that P(God) be non-zero, not that we can estimate P(God) precisely. Once P(God) is non-zero and the payoff under God-exists is enormous, the expected utility of belief swamps the expected utility of disbelief regardless of the precise probability estimate. Modern formalizations (Jordan, Pascal's Wager, 2006) refine this with finite-but-arbitrarily-large utilities to avoid infinite-utility paradoxes; the conclusion is robust to the formalization choice. The objection demands a precision the argument does not require. Failure mode: demanding precision the argument does not need.
3. The Hájek paradox dissolves with finite-utility refinements. Alan Hájek's "Waging War on Pascal's Wager" (2003) raises legitimate technical worries about infinite utilities (mixed strategies dominate, Saint Petersburg paradoxes). Modern defenders (Jordan, McGrew, Schlesinger) respond with: use finite-but-arbitrarily-large utilities (the Wager's force survives); restrict to dominance-reasoning rather than full-EU calculations (no infinite-utility math required); model the asymmetry qualitatively (eternal good vs. earthly loss is qualitatively asymmetric without requiring numerical infinity). The technical paradoxes are real but solvable; they don't undermine the core argument. Failure mode: technical objection that doesn't survive technical refinement.
4. Pragmatic justification is part of practical reason; it is not opposed to truth-seeking. Pascal's argument explicitly acknowledges that the practices it recommends are also the practices that put one in the best position to evaluate the truth-claims of Christianity (study of Scripture, association with believers, prayer, sacramental life). Adopting the practices is not opposed to truth-seeking; it is truth-seeking via the practical mode. The argument also pairs with evidential arguments (Pascal's Pensées contains many evidential arguments for Christianity); the Wager addresses the agent for whom evidential considerations are inconclusive. Failure mode: false dichotomy between pragmatic and truth-tracking reasoning.

Live-cite kit

• Scripture: Joshua 24:15 ("choose for yourselves today whom you will serve"); Mark 8:36 ("what does it profit a man to gain the whole world, and forfeit his soul?"); Hebrews 11:6 (without faith it is impossible to please Him; He rewards those who seek Him).
• Scholarly: Pascal (Pensées §233/418); William James (The Will to Believe, 1896); Jeff Jordan (Pascal's Wager: Pragmatic Arguments and Belief in God, 2006); Ian Hacking ("The Logic of Pascal's Wager", American Philosophical Quarterly 9/2, 1972).
• Aphorism: "You must wager. It is not optional." (Pascal)

Tactical notes

• Lead with the seatbelt analogy, it grounds the principle in everyday rationality the opponent already accepts. Once they grant the principle for traffic-safety, the move to existential-stakes decision is structural.
• Force-commit on the forced-choice character: ask "what are you doing right now if not living as if God doesn't exist? You're already wagering, the question is which wager you're making." Most agnostics implicitly imagine they are not deciding; pin them on the operational reality.
• Do not present this as the primary argument, the Wager is supplementary, addressing the agent who has not yet been moved by evidential arguments. Present it as: "even if the evidence is tied, here's why the practical reasoner should still seek belief."

P2, Belief in God yields infinite (or arbitrarily-large) gain under the God-exists state and minimal loss under the God-does-not-exist state

Affirmative case (second-order arguments)

1. The asymmetric payoff structure. If God exists and one believes: infinite gain (eternal life, communion with God, vindication of one's deepest longings, see Argument from Purpose Meaning and Hope P4). If God does not exist and one believes: small finite loss (perhaps some opportunity costs of religious practice, perhaps some constraint of moral discipline, perhaps social-cultural friction in secular contexts). The asymmetry is enormous; the infinite-vs-finite (or arbitrarily-large-vs-small-finite) gap dominates the calculation.
2. The "minimal loss" claim is empirically supported. Religious practitioners across many studies report higher subjective well-being, stronger social bonds, longer life expectancy, lower rates of depression, anxiety, and addiction (cf. Tyler VanderWeele's work at Harvard School of Public Health on religion-and-health). The this-life costs of belief are not obviously costs; on many empirical measures, belief is beneficial even bracketing eschatological considerations. The "minimal loss" formulation is generous to the atheist, it concedes possible costs that empirical data may not bear out.
3. The "infinite gain" specification fits the longing-form. As Argument from Desire and Argument from Purpose Meaning and Hope establish, the deepest human longings are for infinite satisfaction, eternal life, perfect love, full knowledge, complete redemption. Christianity's God-exists-and-Christianity-is-true scenario delivers exactly the infinite-magnitude object the longings specify. The Wager's "infinite gain" is not arbitrary; it is the satisfaction-fit of the longing's specification.
4. The Christian gospel's particular gift. Beyond the generic-eternal-life consideration, Christianity offers reconciliation with God (Romans 5:1), adoption as children (John 1:12), the indwelling of the Holy Spirit (Romans 8:9-11), participation in the divine nature (2 Peter 1:4), gifts that are themselves of infinite worth. Pascal himself emphasizes the Christ-centered character of the gain; the Wager is for the Christian God, not for a generic deity.

Anticipated objections

1. "There IS substantial loss in religious belief, restrictive moral demands, opportunity costs, social-cultural friction, mental burden."
2. "Religious belief can be harmful, religious wars, sexual repression, intellectual dishonesty, exploitation by clergy, etc."
3. "Eternal life with God is not necessarily a gain, it could be horrific (boring, oppressive, unfree)."
4. "You can't claim 'infinite gain' without first proving Christianity's eschatology, the Wager assumes its own conclusion."

Rebuttals

1. Real moral discipline is one of belief's gains, not losses. What the objection calls "restrictive moral demands" are typically the same demands secular morality affirms (don't murder, lie, betray, abuse) plus some specific Christian disciplines (sexual ethics, sabbath observance, generosity). The empirical record shows these disciplines correlate with better outcomes (relational stability, financial responsibility, mental health), not worse. Opportunity costs are real but typically modest (Sunday morning, tithing, etc.); they are dwarfed by the gains even bracketing eschatology. The "minimal loss" formulation is conservative; the empirical case might support "minimal-or-net-positive loss." Failure mode: assuming what counts as "loss" without empirical examination.
2. Misuse of religion is not the religion. The historical-pathological cases of religious harm (Inquisition, religious wars, clerical abuse) are real and deplorable, but they are misuses of religion that contradict its own internal teaching (cf. Christ's denunciation of religious hypocrisy in Matt 23). The objection trades on conflating Christianity's teaching with its institutional misuse. The relevant comparison is not "atheism's average expression vs Christianity's worst expression" but "atheism's deepest implications vs Christianity's actual teaching." The latter comparison favors Christianity decisively. Failure mode: institutional-misuse confusion with doctrinal content.
3. The "horrible eternity" objection misreads Christian eschatology. Christianity's eternal-life teaching is not a static-boring afterlife but an eternally-deepening communion with infinite God (Gregory of Nyssa's epektasis, see Argument from Desire). The Christian eschaton is more free, more alive, more loving than any earthly state; it is the satisfaction of every deep longing, not the boring afterlife of cultural caricature. The objection commits the strawman fallacy, refuting a non-Christian conception of eternal life rather than the Christian one. Failure mode: caricature of eternal life.
4. The Wager works on Christianity's claims as premised, with Christianity's truth-status as the uncertain element being wagered. The Wager doesn't prove Christianity's eschatology; it argues that if Christianity is even possibly true (non-zero probability), the asymmetric stakes warrant practical-reasoning belief. The argument runs: "consider the worldview-options; among them, Christianity has a non-zero probability and an asymmetric payoff; therefore choose to engage Christianity." The infinite-gain claim is part of the Christian worldview being weighed, not a presupposition smuggled in. Failure mode: circularity charge that misreads the Wager's logical structure.

Live-cite kit

• Scripture: John 17:3 (eternal life as knowing God); 1 Corinthians 2:9 (what God has prepared); Revelation 21:1-5 (new heavens, new earth); Romans 8:18 (sufferings not worthy compared to coming glory).
• Scholarly: Jeff Jordan (Pascal's Wager, 2006, ch. 4-5); Tyler VanderWeele (Religion and Health, ongoing Harvard research); Gregory of Nyssa (epektasis doctrine).
• Aphorism: "Pascal's Wager isn't 'gamble on God', it's 'don't bet your life against an infinite payoff.'"

Tactical notes

• For the "religion is harmful" opponent: separate misuse from teaching. Christ's own denunciation of religious hypocrisy (Matthew 23) is a powerful card, Christianity's worst critic on religious-misuse is Christianity itself.
• For the "eternal life sounds boring" opponent: deploy the Gregory of Nyssa epektasis point, eternal life is eternally-deepening communion, not static rest. Lewis's The Great Divorce and The Last Battle are accessible illustrations.
• Do not promise material prosperity, prosperity-gospel framings of the Wager are theologically and apologetically catastrophic. The Wager is about ultimate-goods, not about earthly health-and-wealth. Many Christians suffer in this life (Heb 11:36-38); the Wager survives because the eternal asymmetry holds.

P3, Disbelief yields infinite (or arbitrarily-large) loss under the God-exists state and small finite gain under the God-does-not-exist state

Affirmative case (second-order arguments)

1. The mirror-image asymmetry. Disbelief carries the inverse risk profile: under God-exists, one misses the infinite gain (and on traditional Christian eschatology, may face active loss, see Hell and Eternal Punishment); under God-does-not-exist, one gains some finite goods (autonomy, intellectual self-respect, freedom from religious discipline). The infinite-vs-finite asymmetry is mirrored on the disbelief side.
2. The "small finite gain" of disbelief is genuinely small. What does the disbeliever gain if disbelief is correct? Some Sunday mornings; freedom from tithe; freedom from sexual-ethical constraint; perhaps a sense of intellectual independence. These are real but modest goods. The empirical-outcome research (VanderWeele et al.) suggests the disbeliever may not even gain these on average, religious practitioners often have higher subjective well-being. The "gain of disbelief" is small even on optimistic accounting.
3. Even the agnostic position carries the disbelief-risk profile. The agnostic operationally lives as the disbeliever does (no church, no prayer, no Christian discipline), and therefore inherits the same risk profile. "I'm not deciding" is practically a decision against belief; the risk-calculation applies. (Pascal's force-commit move: agnosticism is not a third option; it is a flavor of disbelief.)
4. The longing-frustration cost. Beyond the eschatological asymmetry, disbelief carries the this-life cost of having unsatisfiable longings (per Argument from Purpose Meaning and Hope P3), the deepest human longings remain frustrated under naturalism. The disbeliever's "small finite gain" may be partially offset by this this-life cost; the total disbelief-payoff is modest at best, deeply negative at worst.

Anticipated objections

1. "There's no 'loss' on disbelief if God doesn't exist, you just don't get the (non-existent) gain. The 'loss' framing is question-begging."
2. "Hell is not in the calculation, many liberal Christians and pluralists don't believe in hell, so the disbelief-loss is not infinite."
3. "The 'small finite gain' of disbelief is actually substantial, intellectual integrity, autonomy, freedom from religious manipulation are major goods."
4. "This argument generates fear-based belief, which is morally and theologically corrupt."

Rebuttals

1. The framing tracks the structural asymmetry, not a question-begging assumption. Granted, on the God-doesn't-exist state, both believer and disbeliever simply face their finite earthly lives; neither "loses" infinity (because there is no infinity to lose). But the argument's force is the expected-value asymmetry across both states: the believer has a chance at infinite gain; the disbeliever has no chance at it. That's the asymmetry the Wager identifies. The objection misreads the Wager as claiming both states are symmetric; it doesn't, it claims the across-states expected utility favors belief. Failure mode: confusing one-state analysis with cross-states expected-utility.
2. The Wager works even if hell is bracketed; it gains additional force if hell is in the calculation. The "infinite gain" of belief (eternal life with God) is itself sufficient to drive the asymmetry; we don't need the "infinite loss" of hell to make the Wager work. If you reject hell-doctrine, the Wager still says: belief has a chance at infinite-positive, disbelief has none; this is sufficient. If you accept hell-doctrine, the asymmetry is even sharper. (See Hell and Eternal Punishment for the detailed hell-doctrine arguments; the Wager is robust across orthodox positions.) Failure mode: assuming the Wager requires hell-doctrine when it doesn't.
3. Intellectual integrity is also available to the believer, and is often better served by belief. The objection assumes intellectual integrity requires disbelief; this is a substantive philosophical claim that the apologetic case for Christianity contests. Many intellectually-rigorous philosophers, scientists, and scholars are believers (Plantinga, Swinburne, Polkinghorne, Lennox, Collins). Intellectual integrity requires honest engagement with the arguments, not a particular conclusion. The "autonomy" argument also smuggles in a controversial value-claim (autonomy is the highest good); Christianity offers a different account of the good (communion with God), which the objector cannot defeat by appeal to autonomy without begging the question. Failure mode: assuming intellectual integrity entails disbelief; assuming autonomy is the highest good.
4. Self-interest is an honest motivation in practical reason; the practices it generates are virtuous regardless of motivation. Pascal explicitly addresses this: the practices one is moved to (prayer, community, service, study) are the same practices a sincere believer adopts; over time, these practices form the character, including the genuine belief. The eventual belief is not insincere; the initial motivation (self-interest under uncertainty) is one legitimate path into the practices. (Compare: the person who diets initially out of vanity may end up genuinely valuing health.) Calling self-interested wagering "morally corrupt" applies a moral standard the Wager itself does not endorse, the Wager is about getting started; the formed character that emerges is what Christian discipleship aims at. Failure mode: purity-test on motivations that ignores the formative function of practice.

Live-cite kit

• Scripture: Mark 8:36; Matthew 16:26; Luke 12:16-21 (rich fool storing up treasure but unprepared for death); 2 Corinthians 6:2 ("now is the day of salvation").
• Scholarly: Pascal (Pensées §233/418); Jordan (Pascal's Wager, 2006, ch. 6-7); William James (The Will to Believe, 1896).
• Aphorism: "If you bet against God and you're right, you've gained little. If you bet against God and you're wrong, you've lost everything."

Tactical notes

• For the "fear-based belief is corrupt" opponent: deploy the diet analogy (vanity → health), the initial motivation does not determine the eventual character. The Christian tradition has substantial pastoral wisdom on motivation-purification through practice (Augustine, Bernard, Edwards).
• For the "no-hell" liberal opponent: bracket hell entirely. The Wager works on the asymmetric gain alone. State this explicitly: "even if you don't believe in hell, the chance at infinite gain on belief vs. no chance on disbelief is the Wager's force."
• Do not lean on hell to make the case in live debate, for many opponents this triggers immediate dismissal. Lead with the gain-asymmetry; introduce hell-considerations as a secondary intensifier only when the audience is ready.

Conclusion

Belief in God dominates disbelief in expected utility; the rational practical agent should seek belief. Even bracketing all evidential arguments for God, the practical reasoner should seek belief, should pursue the practices (church attendance, Scripture reading, prayer, association with believers) that Pascal identifies as the path by which belief is cultivated. The Wager is a gateway argument, designed to move the inertial agnostic into engagement, not the primary case for Christian truth. Combined with evidential arguments (cosmological, moral, historical, comparative-religion, see Christian God is the Only True God), the Wager addresses the will while the evidential arguments address the intellect; both are needed for full conversion.

Pascal's classical formulation: "You must wager. It is not optional… If you gain, you gain all; if you lose, you lose nothing. Wager, then, without hesitation, that He is."

Master objections to the argument as a whole

1. The "many gods" objection (Diderot, Mackie): "Why wager on the Christian God specifically? Other religions also promise infinite goods to believers and infinite loss to unbelievers; the wager is indeterminate among them." Reply: the Wager works conjointly with evidential considerations that narrow the live options. Among the religions that have a non-zero probability for any given agent, the Wager favors the one with the strongest evidential and existential case (which the Christian apologist argues is Christianity, see Christian God is the Only True God). For most Western agents, the relevant live options are: Christianity, secular naturalism, and (for some) Islam. The Wager among these favors Christianity, especially given the historical-resurrection case (Argument from the Resurrection) that distinguishes Christianity from other live options. Failure mode: ignoring the evidential narrowing of live options.
2. The "belief cannot be willed" objection: "Belief is not under direct voluntary control; you cannot simply decide to believe what you find unconvincing." Reply: Pascal's response (Pensées §233), one cannot directly will belief, but one can will the practices (church attendance, prayer, study, association) that, over time, dispose toward belief. "This will quite naturally make you believe." The choice is for the practices, not directly for the belief. (See P1 rebuttal 1.) Failure mode: category-conflation between belief and practice.
3. The "insincere belief doesn't count" objection: "A God worth believing in would not be fooled by mercenary belief motivated only by self-interest." Reply: the practices Pascal recommends are the same ones a sincere believer would adopt; they form the character that yields genuine belief; the eventual belief is not insincere. The Christian tradition has substantial pastoral wisdom on motivation-purification (Augustine on cupiditas → caritas; Edwards on gracious affections). The initial motivation is not the eventual character. Failure mode: purity-test on initial motivations.
4. The "decision-theory paradox" objection (Hájek 2003): "Infinite utilities create paradoxes (mixed strategies dominate; Saint Petersburg paradoxes)." Reply: defenders refine the formalism, finite-but-arbitrarily-large utilities yield similar conclusions without paradox; dominance-reasoning (rather than full EU calculation) sidesteps infinite-utility math; qualitative-asymmetry analysis suffices for the core conclusion. (Jordan, Pascal's Wager, 2006, ch. 8.) Failure mode: technical objection that doesn't survive technical refinement.

William James's Will to Believe extension

William James's 1896 essay reframes the wager-style argument philosophically. James's conditions for legitimate "will to believe":

1. Live option, both possibilities are real for the agent (not, e.g., wagering on whether the moon is made of green cheese).
2. Forced option, there is no neutral middle ground; not deciding is deciding.
3. Momentous option, the stakes are significant.

Under these conditions, the agnostic posture (waiting for sufficient evidence) is not neutrality but is a positive choice to live as if the option were not real. James argues that for some genuine, forced, momentous questions, including the religious question, willing to believe on grounds beyond strict evidence is rationally permissible, even required.

Tactical opening / closing

Opening line: "Suppose for a moment the evidence for God is exactly tied, you can't tell either way. What do you do? Do you flip a coin? Refuse to engage? Or do you notice that the stakes are massively asymmetric, and that that tells you something about how to act?"

Closing landing strip: "The Wager doesn't prove Christianity is true. It says: if you can't see your way to belief on evidence alone, you still have to act, and acting as if God exists is the rational practical move. The next step isn't to assent intellectually; it's to engage the practices that put you in the best position to evaluate the question."

Patristic / scholarly note

Pascal himself:

• Blaise Pascal (Pensées §233 Brunschvicg / §418 Lafuma, 1670), locus classicus; written incomplete (Pascal died before finishing the Apologie); the Wager is one fragment in a larger argumentative project. Pascal's intent: move the worldly libertine from studied indifference to engaged seeking.

18th-19th c. critics:

• Voltaire (Lettres philosophiques, 1734) and Diderot scorned the Wager as religious-utilitarian special pleading; the many-gods objection traces to this period

William James:

• The Will to Believe (1896), most influential 19th-century philosophical engagement; reframes the Wager as defense of voluntarism in belief-formation under specific conditions

Modern philosophical:

• Ian Hacking (Why Does Language Matter to Philosophy?, 1975; "The Logic of Pascal's Wager", 1972), standard formal treatment
• Jeff Jordan (Pascal's Wager: Pragmatic Arguments and Belief in God, 2006), most extensive monograph defense
• Alan Hájek ("Waging War on Pascal's Wager", Philosophical Review 112/1, 2003), best-known modern critique
• Lara Buchak ("Can it be rational to have faith?", 2012), contemporary decision-theoretic defense of religious commitment

Theological reception:

• Karl Barth and the broader Reformed tradition: cool to the Wager, preferring evidential or revelational arguments; calculating self-interest is no foundation for genuine faith
• Roman Catholic reception: mixed (Pascal himself was Jansenist-leaning Catholic; Jesuit reception was hostile)
• Evangelical reception (20th-21st c.): moderate, the Wager is often cited as secondary / supplementary, not the primary case
• Peter Kreeft (Christianity for Modern Pagans, 1993), sympathetic Catholic interpretation of Pascal

Contemporary apologetic deployment:

• William Lane Craig (Reasonable Faith), tactical use as secondary argument
• Tim Keller (The Reason for God, 2008), pastoral framing of the Wager's existential force

Inference rules used

• Decision Theory / Expected Utility Theory, choose the option with the highest expected utility under uncertainty
• Practical Reasoning, distinct from theoretical / evidential reasoning; addresses what to do rather than what to believe in the strict evidential sense
• Dominance Reasoning, one option is at least as good in every state and strictly better in some
