About this ebook
Even if God and evil are compatible, it remains hotly contested whether evil renders belief in God unreasonable. The Evidential Argument from Evil presents five classic statements on this issue by eminent philosophers and theologians, and places them in dialogue with eleven original essays reflecting new thinking by these and other scholars.
The volume focuses on two versions of the argument. The first affirms that there is no reason for God to permit either certain specific horrors or the variety and profusion of undeserved suffering. The second asserts that pleasure and pain, given their biological role, are better explained by hypotheses other than theism. Contributors include William P. Alston, Paul Draper, Richard M. Gale, Daniel Howard-Snyder, Alvin Plantinga, William L. Rowe, Bruce Russell, Eleonore Stump, Richard G. Swinburne, Peter van Inwagen, and Stephen John Wykstra.

Reviews for The Evidential Argument from Evil
2 ratings1 review
- Rating: 1 out of 5 stars1/5You claim that per logical argument: for God to have a morally justifying reason to permit evil He could prevent AND the existence of evil there is an inconsistency that proves that God does not exist. So much so that you gave yourself the freedom to imagine that you have sent the argument FOR God to the “garbage of history” so to say. Actually God has an “extremely morally justifiable reason” to allow evil into this world that He could have prevented and that is “And God created man in his own image, in the image of God created he him; male and female created he them.”Genesis 1:27 He did not create Artificial intelligence He created minds after His own likeness, with free wills. And He will not allow Himself though He can to subdue our free wills, hence plenty can mock Him, deny His existence, blaspheme Him. However, being Omnipotent He can make the greatest good out of the greatest evil. The Redemption of all mankind out of the Death and Cross of the Son of God. So there is a morally justifiable reason for God that caused Him to allow evil into the world.
Secondly: as to the evidential argument from evil. This is even more ridiculous. You or someone named mr Lowe says : there is evil in this earth. And because there is evil God does not exist. Well excuse me but duh!! There is Good on this earth. There is beauty on this earth. Why doesn’t it all crumble down over our ungrateful heads. Why don’t those planets out there just go berserk and bump into each other instead of circling in their orbits. And more importantly since you are so intelligently proving that God doesn’t exist what is keeping you going. What is the purpose of your life as opposed to the purpose of your not living? Why don’t you just kill yourself right now? Why don’t you rob your neighbor? Don’t you know it is God who says not to rob him? So go rob him then kill him. It’s not wrong if God doesn’t exist. You’re ok. ?

The Evidential Argument from Evil - Daniel Howard-Snyder
PREFACE
When I was a student at Syracuse University, I once told an acquaintance in the English Department that my dissertation was on the problem of evil. I recall her reply as though I heard it yesterday: The problem of evil? Isn’t that old hat? I mean, what more can be said after Ivan Karamazov?
Apparently, quite a bit. Barry Whitney recently published a bibliography of over 4,200 philosophical and theological writings on the topic, all published from 1960 to 1990. That’s nearly one publication every two and a half days. One might rightly wonder how much of this torrent of literature is any good, but one certainly cannot seriously question whether the problem of evil continues to capture the interest of philosophers and theologians alike. It’s hardly old hat.
Philosophical study of the problem of evil has shifted from issues having to do with the compatibility of theism and evil to what is often called the evidential problem of evil.
My aim in collecting the essays of this book has been to bring together recent work on the latter topic. But I didn’t want just another collection of previously published pieces. Rather, I wanted a handful of the very best previously published essays to act as a stage upon which dialogue might progress, a place where new work might be done. However, I also wanted a collection that a student or educated layperson could understand, with only minimal assistance from an instructor or a course or two in basic philosophy. Each of the authors has written with these goals in mind. An instructor might easily use many of the essays of this book in an undergraduate course in the philosophy of religion.
A book of this sort requires the cooperation of many individuals. Each new essay was refereed by at least one other contributor, but usually more. Moreover, many other philosophers cajoled, provoked, challenged and otherwise pressed the contributors to do better than they had initially done. It is with heartfelt gratitude that I thank Robert Adams, Mark Brown, David Conway, Mark Cullison, Martin Curd, Evan Fales, Gregory Ganssle, Phillip Goggans, William Gustason, William Hasker, Bruce Hauptli, Frances Howard-Snyder, Hud Hudson, Jeff Jordan, Norman Kretzmann, C. Stephen Layman, Thomas Loughran, Alastair Norcross, David O’Connor, John O’Leary-Hawthorne, John Schellenberg, Stefan Sencerz, James Sennett, Thomas Senor, James Taylor, William Wainwright, Mark Webb, and David Wideker. (If you ought to be on this list, please forgive me my negligence.) For encouragement from the start and for help in other ways, I wish to thank William Alston, Jan Cover, Paul Draper, Janet Rabinowitch, Stewart Thau, Peter van Inwagen, Thomas Trzyna, Merold Westphal, and the departmental staffs of Syracuse University, Wayne State University, and Seattle Pacific University.
Finally, my greatest debt of gratitude is to my best friend and wife, who just reminded me that I have ninety-five midterms to grade by tomorrow. This book is for you, Frances.

INTRODUCTION:
The Evidential Argument from Evil
1. The Problem
of Evil
Evil, it is often said, poses a problem for theism, the view that there is an omnipotent, omniscient, and perfectly good being, God,
for short. This problem is usually called the problem of evil.
But this is a bad name for what philosophers study under that rubric. They study what is better thought of as an argument, or a host of arguments, rather than a problem. Of course, an argument from evil against theism can be both an argument and a problem. Some people realize this for the first time when they assert an argument from evil in print and someone publishes a reply in which numerous defects and oversights are laid bare for the public eye. And if it turns out that there is a God and He doesn’t take kindly to such arguments, then an argument from evil might be a big problem, a very big problem, for one who sincerely propounds it. Typically, however, an argument from evil is not thought to be a problem for the atheist. But if not for the atheist, for whom is an argument from evil a problem
?
Perhaps the theist. The theist, however, may rightly find the premises or inferences of arguments from evil dubious and hence no problem at all. Perhaps, then, an argument from evil is a problem for the theist who finds all its premises and inferences compelling. But even then it might not be a problem, since she might have more compelling grounds to reject the conclusion than to accept all the premises and inferences. Perhaps, then, an argument from evil is a problem for the theist who finds all its premises and inferences compelling and who has lousy grounds for believing theism and she knows it. In that case an argument from evil might be a problem for the theist, at least if she is reasonable. For she might feel strongly inclined to believe there is no God, or at least that, in some sense, she ought to believe that there is no God. No doubt, this could be a troubling state of mind, one that might properly be called a problem. But in that case calling what philosophers study under the name the problem of evil
a problem is highly misleading. For no philosophers today take the state of mind of the cognitively dissonant theist as their object of study when they study what they refer to as the problem of evil.
One might think that what philosophers study under the name the problem of evil
are arguments that should lead the theist to the cognitively dissonant state of mind just sketched, and so, by extension, such an argument is rightly called a problem for the theist. But this rationale for calling what philosophers study under the name the problem of evil
a problem is highly contentious, to say the least. For an argument from evil should lead the theist to cognitive dissonance only if the argument is good, and there is broad disagreement over whether any argument from evil is good. Of course, those convinced that some argument from evil is not defective and that it should lead the theist to cognitive dissonance might properly call it a problem. But why should the rest of us join them? It seems to me, therefore, that we, or at least a great many of us, should stop using the problem of evil
as a name for what philosophers study under that rubric. If a singular term must be used, "the argument from evil" is more apt.
It is customary to distinguish two families of arguments from evil, calling one logical,
deductive,
or a priori
and calling the other evidential,
inductive,
empirical,
probabilistic,
or a posteriori.
But these too are poor names for that to which they refer. For, if their names are any guide to the contrast (as they are supposed to be), logic is relevant to the members of the first family but not the second, and the members of the second family are meant to be evidence while the first are not. But this is hardly the case. As the chapters in this book indicate, evidential arguments involve quite a bit of logic, both deductive and inductive, and everyone agrees that they must stand up to the canons of logic. And every undeniably logical argument is superlative evidence against theism, if it is a good argument. Moreover, every undeniably logical argument has a premise that can only be known a posteriori, by empirical means, namely, a premise about evil, e.g., that it exists. And every undeniably evidential argument has a premise that can only be known a priori, e.g., a premise about what counts as good evidence or what we rightly expect from God in the way of preventing evil. And many inductive
arguments from evil are, on the face of it, deductively structured.
So what is this distinction between logical and evidential arguments from evil?
2. Logical Arguments from Evil
Perhaps we can best get at the question by looking at the most famous members of each family. If there is a distinction between logical and evidential arguments from evil, then J. L. Mackie’s argument is the paradigm member of the logical family. Mackie asserted that not only can it be shown that
religious beliefs lack rational support, but that they are positively irrational, that the several parts of the essential theological doctrine are inconsistent with one another, so that the theologian . . . must be prepared to believe, not merely what cannot be proved, but what can be disproved from other beliefs that he also holds.¹
The putative disproof to which Mackie alluded is the problem of evil. As Mackie conceived of it, the problem of evil was a logical problem, the problem of clarifying and reconciling a number of beliefs
that were essential parts of most theological positions.
The three beliefs he had in mind were these: God is omnipotent; God is wholly good; and yet evil exists.
² Mackie was aware that, on the face of it, there was no inconsistency here. Thus, he said,
to show it we need some additional premises, or perhaps some quasi-logical rules connecting the terms good,
and evil,
and omnipotent.
These additional principles are that good is opposed to evil, in such a way that a good thing always eliminates evil as far as it can, and that there are no limits to what an omnipotent thing can do. From these it follows that a good omnipotent thing eliminates evil completely, and then the propositions that a good omnipotent thing exists, and that evil exists, are incompatible.
Nearly forty years have passed since Mackie published his famous logical problem
of evil, as he called it. (So far as I know, this is where we get the name from.) Like logical positivism, Mackie’s argument has found its way to the dustbin of philosophical fashions. Why?
Mackie claimed it was impossible for
G. God is omnipotent and God is wholly good,
and
E. Evil exists
both to be true. This would be evident, he said, in light of the moral principle
MP1. A good thing always eliminates evil as far as it can,
and the proposition
L. There are no limits to what an omnipotent thing can do.
But G, MP1, and L rule out the possibility of E only if both L and MP1 are necessary truths. If they are not, a wholly good omnipotent thing, say, a person, might permit evil, either because her goodness does not rule out the possibility or because she cannot eliminate evil entirely. Are they both necessary truths? Properly understood, L is.³ But MP1 is not. If a wholly good person had a morally justifying reason to permit evil she could prevent, she might not eliminate evil as far as she can. A more plausible moral principle for a Mackie-style logical argument from evil is this:
MP2. A wholly good thing eliminates evil as far as it can, unless it has a morally justifying reason not to.
But G, MP2, and L rule out the possibility of E only if it is a necessary truth that there is no morally justifying reason for a wholly good thing to permit preventable evil. However, nothing we know rules out the possibility that there is a morally justifying reason for a wholly good thing to permit evil she could prevent. Indeed, consider the proposition that
J. There is a morally justifying reason for God to permit evil He could prevent, a reason we could not know of, and He permits evil for that reason, and evil results.
Nothing we know rules out J as a possibility; and nothing we know rules out the possibility that G and J are both true. But if both G and J were true, then E would be too. And it would also be true that we could not know the reason God permitted evil. Thus, for all we know, G and E are compatible even if we cannot think of a morally justifying reason for God to permit evil.⁴
Mackie’s aim was to disprove
theism, and thus to show that theistic belief is positively irrational.
Toward that end, his logical argument had a premise that said theism is incompatible with some fact about evil. But note that it was not any old fact about evil that was purportedly incompatible with theism. It was a fact that we know with certainty: that there is evil. Of course, there are other facts that might have served his purposes just as well, e.g., the fact that there is suffering that results from natural disturbances like earthquakes and diseases (so-called natural evil
), or the fact that a particular infant was intentionally scalded to death with boiling water by its parents on November 24, 1991, in Seattle, or the fact that there is a whole lot of undeserved horrific evil in the world. Each of these facts can be known with certainty. But our present point is this: allowing that Mackie’s argument is a guide, we can think of a logical argument from evil
as one which has a premise that says God and some known fact about evil are incompatible, and we can think of an evidential argument from evil
as one that lacks such a premise. That is, we should expect that paradigm members of the evidential family will either (i) entirely lack a premise that says that God is incompatible with some fact about evil, or (ii) if they have such a premise, the putative fact about evil cannot be known with certainty, e.g., it might be claimed to be probable to some significant degree, or reasonably believed. As it turns out, this is what we find.
3. Evidential Arguments from Evil
In chapter 1, William Rowe puts the evidential argument from evil roughly like this:
1. There exist instances of intense suffering that God could have prevented without thereby losing some greater good.
2. God would prevent the occurrence of any intense suffering He could, unless He could not do so without thereby losing some greater good.
3. So, God does not exist.
Premise 2 says that the existence of God is incompatible with each instance of preventable intense suffering the permission of which is not required for some greater good. We have here, then, an argument from evil that asserts that the existence of God is incompatible with some purported fact about evil. But note that it is not a known fact. As Rowe points out, we cannot know with certainty that instances of suffering of the sort described in 1 do occur in the world.
Rather, he says, we have rational grounds
for believing 1, grounds which render 1 probable to the degree that it is more reasonable to believe 1 than to suspend judgment on 1.
So this popular version of the evidential argument conforms to our distinction.
Since 1979, Rowe has articulated two other evidential arguments from evil, both of which he discusses in chapter 14. They rely on the following inference:
P. No good we know of justifies God in permitting E1 and E2 (where E1 and E2 are cases of especially horrific evil); so, it is quite probable that
Q. No good at all justifies God in permitting E1 and E2.
Both arguments have what amounts to the premise that Q entails there is no God. However, they differ over what bridges the gap between P and Q. One asserts that we are justified in moving from P to Q in the same way we are justified in making the many inferences we constantly make from the known to the unknown,
namely, by way of enumerative generalization. The other employs Bayes’s Theorem, and certain argued-for assignments of value to it, to conclude that P makes Q considerably more likely than not. In both cases there is a premise, i.e. Q, that says some purported fact about evil is incompatible with theism. But, again, note that purported fact is not known. Rather, Q is argued for in the way suggested. Of course, there are other grounds for believing Q on P. (See, e.g., chapters 10 and 11.) But in each case, Q is based on grounds insufficient for knowing Q with certainty. At best, these arguments make Q likely to a significant degree or reasonable to believe, given P and other information.
Each of the evidential arguments thus far mentioned has a premise that says some fact about evil is incompatible with theism. It is then argued that the fact in question is likely to some degree or another or reasonable to believe, given some other fact which is itself known or argued for. But an evidential argument might not proceed like this. For example, in chapter 14 Rowe defends a Bayesian version of the evidential argument that bypasses Q altogether, one that goes straight from P to the conclusion that theism is probably false. Another example is Paul Draper’s argument in chapter 2. Draper asks us to consider a serious alternative hypothesis to theism. He calls it the hypothesis of indifference (HI):
Neither the nature nor the condition of sentient beings on earth is the result of benevolent or malevolent actions performed by non-human persons.
Let O stand for a statement reporting known facts about sentient creatures experiencing pain and pleasure. And let a theistic story be any attempt to explain O in terms of theism. Draper claims that, given what we know apart from O, HI explains O much better than theism. He glosses this as the claim that
C. O is antecedently much more probable on the assumption that HI is true than on the assumption that theism is true.
That is, given what we know apart from O, the probability of O on HI is much greater than the probability of O on theism, or, in short, Pr(O/HI) >! Pr(O/theism). Draper’s premises are:
1. Given the biological role played by both pain and pleasure in organisms, independent of the effect of theistic stories on Pr(O/theism), C is true.
2. Theistic stories do not significantly raise Pr(O/theism).
If C is true, says Draper, we have a prima facie reason to reject theism. For present purposes, note that, even though O is known, Draper’s argument does not employ a premise that says that theism and O are incompatible. So it too conforms to our distinction between logical and evidential arguments from evil.
While my sampling of arguments is necessarily limited, it seems that we can distinguish arguments from evil along the lines suggested, even though that distinction is badly named. So-called logical
arguments from evil have a premise that says theism is incompatible with some known fact about evil; so-called evidential
arguments do not.
While we may easily draw this distinction, we are hard pressed to defend its significance. I’m afraid I don’t have much to say about the matter, except for the obvious. I mean, whenever one meets what its author purports to be an argument from evil (in contrast with, say, the sort of response to horrendous evil that you might find in Albert Camus’s The Plague or Elie Wiesel’s Night), one ought to consider whether the author intends to assert that facts about evil known with certainty are incompatible with theism. If she does, then one should query why the argument is not dubious for the same reason that Mackie’s argument from evil is dubious. If she does not—that is, if she intends to say that facts about evil which are known with certainty make theism significantly unlikely, or that theism is incompatible with certain facts about evil that are themselves quite likely—then one needs to think hard about the sorts of issues this book is about.
4. Central Issues in Evidential Arguments from Evil
It would be pointless, and a grave injustice, were I to try here to summarize the work of each contributor. Instead, I shall briefly sketch what I think are some of the main issues at stake in the debate over the evidential argument from evil and where they are discussed in the essays that follow.
4.1 ISSUES COMMON TO EVERY EVIDENTIAL ARGUMENT FROM EVIL
Three fundamental issues arise with respect to every evidential argument from evil.
First, one might argue that even if an evidential argument counts against theism, the total evidence makes theism quite likely or sufficiently reasonable to believe. This raises with a vengeance the question of whether, on the whole, the total evidence supports theism. I can’t go into that here.⁵ Alvin Plantinga, however, gives this question an interesting twist toward the end of chapters 5 and 13. After finding fault with different evidential arguments from evil, he argues that even if they showed what they purported to show the theist might well have much better nonpropositional grounds for her theistic belief than any argument from evil provides her with propositional grounds against it. And whether this is so is largely a matter of whether God has given us certain cognitive powers, as classical theism asserts. Thus, according to Plantinga, whether theistic belief is rendered unreasonable by any evidential argument from evil depends on whether classical theism is true.⁶
A second issue that cuts across versions of the evidential argument from evil is this: suppose we knew of some plausible justifying reason for God to permit the sorts of evil we find in our world, a theodicy. In that case, one might think that evil would not count against theism at all. In chapter 3, Richard Swinburne argues that we know of a number of actual greater goods that moral and natural evil serve and that these goods constitute major strands in a viable theodicy. In chapter 4, Eleonore Stump argues that reflection on Aquinas’s commentary on Job and his general account of suffering as medicine for a cancer that hinders us from eternal communion with God shows that how we look at suffering is a consequence of much larger issues, specifically, our views about the nature of human happiness and the goal of human life. She urges that to assess the prospects for theodicy we must first resolve these larger issues. I refer the reader to the bibliography for other works of theodicy, e.g., those by Marilyn McCord Adams and John Hick.
Third, evidential arguments from evil purport to show that it is likely to some degree or another that there is no God. But what concept of probability is being used here? I suspect that different concepts are employed in the arguments of, say, Rowe and Draper. Draper explicitly says that he means to be using what is called epistemic probability, as opposed to some more objective concept, e.g., statistical probability. Many interesting questions lurk here, some of which are taken up by Draper (chapters 2 and 9), Plantinga (chapters 5 and 13), and Peter van Inwagen (chapters 8 and 12). Be sure to read the notes for these chapters.
4.2 ARGUMENTS FROM INSCRUTABLE EVIL
Let us briefly turn to the most popular version of the evidential argument from evil, the argument that in various ways is defended by Rowe (chapters 1 and 14), Russell (chapter 10) and Gale (chapter 11). They claim that there is no justifying reason for God to permit certain particular horrific evils. At bottom, their basis for saying this is that they cannot see how any reason they know of justifies God in permitting those particular evils, or that no reason they know of does the trick. Call this the inference from inscrutable to pointless evil.
Three main issues lurk here.
First, we need to consider whether there are any plausible reasons that would justify God in permitting the sorts of horrors Rowe et al. point to. Even if we can think of reasons for God to permit moral and natural evil, however, it does not follow that they justify God in permitting any particular evil. And it is particular evils that Rowe et al. point to. An interesting question arises: What is it, exactly, that God must have a reason to permit? Suppose He has a reason to permit a good deal of undeserved horrific evil. Must He also have a reason to permit each particular horror, or certain narrowly defined kinds of horrific evil, e.g., murder, child abuse, or suffering from disease? Of course, He might have such a reason. But Rowe et al. assume that He must. This issue is taken up explicitly in note 11 of van Inwagen’s chapter 8, note 12 in Russell’s chapter 10, van Inwagen’s reply to Russell in chapter 12 and in §1 of chapter 15.⁷
The second main issue is raised most explicitly by Rowe (chapters 1 and 14) and William Alston (chapters 6 and 16). While Alston agrees that we cannot see how any reason we know of justifies God in permitting the particular evils Rowe et al. point to, he argues that they wrongly infer that no good we know of justifies God in permitting them, since we are in no position to make that judgment. Our grasp of the nature of some goods we know of may not allow us to assess their value properly. Moreover, our grasp of the conditions of their realization may not allow us to judge that they could have been realized without God permitting the evil in question. Rowe, however, cites several considerations that he believes make it eminently reasonable to affirm that no good we know of justifies God.
The third main issue is whether the inference from inscrutable to pointless evil is any good. One might argue that the best explanation of inscrutable evil is pointless evil (Russell, chapter 10),⁸ or that if some good justified God, we would very likely know of it (Gale, chapter 11),⁹ or that it is improbable in the extreme that there are goods outside our ken (Gale),¹⁰ or that skepticism follows if we deny that certain horrific evils are not justifiably permitted by God (Russell and Gale), or that we have conducted the relevant search for reasons for God to permit these things (Russell), or that certain assignments to a Bayes theoretic formulation of the argument are justified (Rowe, chapter 14). In different ways, Alston (chapters 6 and 16), Plantinga (chapter 5), Wykstra (chapter 7), and the author of chapter 15 try to contribute to the dual thesis that not only are these bad reasons to draw the inference from inscrutable to pointless evil, but there is good reason to believe that the inference is positively irrational, to borrow Mackie’s happy phrase.
4.3. EXPLANATORY ARGUMENTS
Contrary to popular opinion, not every evidential argument from evil employs the premise that there is no justifying reason for God to permit certain facts about evil. Recall the argument I attributed to Draper earlier, the conclusion of which is that the Hypothesis of Indifference (HI) explains known facts about sentient creatures experiencing pain and pleasure (O) much better than theism does, which he glosses as the claim that Pr(O/HI) >! Pr(O/theism). A number of interesting issues need further study.
First, one frequently hears that to evaluate the truth of theism we must assess whether it is the best explanation of some relevant range of data. But why suppose that theism is in the business of explaining anything, much less various facts about evil? Is theism an explanation? Is theistic belief properly treated as belief that a certain explanation is true, better than its competitors, or some such thing? Draper and others—both theists and nontheists—assume affirmative answers to these questions; but, so far as I know, no one has defended those assumptions in any convincing way. This issue is central to explanatory arguments from evil. For if theism is not properly treated as an explanation (and we need not stoop to neo-Wittgensteinian perversions to say it is not), then those who cavil at theism for being a bad explanation are caviling up the wrong tree.¹¹
Second, in chapter 16, Alston raises a number of considerations that shed doubt on whether Draper’s argument really should be thought of as an explanatory argument from evil. At best, Draper focuses on only one factor in determining whether one explanation is better than another. And neither of the explanans he compares—theism and HI—can be properly thought of as explanations, since neither is specific enough to throw any light on why the explanandum, O, occurred. Perhaps there is little point in comparing the explanatory power of theism and HI vis-à-vis O without using theistic or HI-istic stories as bridge principles that shed some light on why O occurred.
Third, is it really true that, given the biological role played by both pain and pleasure in organisms, and that independent of the effect of theistic stories on Pr(O/theism), Pr(O/HI) >! Pr(O/theism)? In chapter 2, Draper defends an affirmative answer, while in chapter 13, Plantinga defends a negative one.¹²
Fourth, Draper argued that there were only two viable responses to his argument: (i) refute the argument by telling a theistic story that significantly raised Pr(O/theism), or (ii) make a case for preferring theism to HI that outweighs the prima facie case for preferring HI to theism. According to Peter van Inwagen, this list of responses is incomplete. If we simply could not know whether to expect O on theism, then we would be in no position to judge that Pr(O/HI) >! Pr(O/theism), and this, argues van Inwagen in chapter 8, is indeed the case. In chapters 9, 10, and 11, Draper, Russell, and Gale argue that the epistemic and moral principles van Inwagen uses and assumes lead to objectionable versions of skepticism. Van Inwagen clarifies his view and defends himself in chapter 12.
As a matter of practical necessity I have only gestured at some of the issues that the authors in this book address. Nothing can replace the careful study of their essays, to which I hope my reader now quickly turns.¹³

THE EVIDENTIAL ARGUMENT FROM EVIL
WILLIAM L. ROWE
1.
The Problem of Evil and Some Varieties of Atheism
This chapter is concerned with three interrelated questions. The first is: Is there an argument for atheism based on the existence of evil that may rationally justify someone in being an atheist? To this first question I give an affirmative answer and try to support that answer by setting forth a strong argument for atheism based on the existence of evil.¹ The second question is: How can the theist best defend his position against the argument for atheism based on the existence of evil? In response to this question I try to describe what may be an adequate rational defense for theism against any argument for atheism based on the existence of evil. The final question is: What position should the informed atheist take concerning the rationality of theistic belief? Three different answers an atheist may give to this question serve to distinguish three varieties of atheism: unfriendly atheism, indifferent atheism, and friendly atheism. In the final part of the paper I discuss and defend the position of friendly atheism.
Before we consider the argument from evil, we need to distinguish a narrow and a broad sense of the terms theist,
atheist,
and agnostic.
By a theist
in the narrow sense I mean someone who believes in the existence of an omnipotent, omniscient, eternal, supremely good being who created the world. By a theist
in the broad sense I mean someone who believes in the existence of some sort of divine being or divine reality. To be a theist in the narrow sense is also to be a theist in the broad sense, but one may be a theist in the broad sense—as was Paul Tillich—without believing that there is a supremely good, omnipotent, omniscient, eternal being who created the world. Similar distinctions must be made between a narrow and a broad sense of the terms atheist
and agnostic.
To be an atheist in the broad sense is to deny the existence of any sort of divine being or divine reality. Tillich was not an atheist in the broad sense. But he was an atheist in the narrow sense, for he denied that there exists a divine being that is all-knowing, all-powerful, and perfectly good. In this paper I will be using the terms theism,
atheist,
agnosticism,
and agnostic
in the narrow sense, not in the broad sense.
I
In developing the argument for atheism based on the existence of evil, it will be useful to focus on some particular evil that our world contains in considerable abundance. Intense human and animal suffering, for example, occurs daily and in great plenitude in our world. Such intense suffering is a clear case of evil. Of course, if the intense suffering leads to some greater good, a good we could not have obtained without undergoing the suffering in question, we might conclude that the suffering is justified, but it remains an evil nevertheless. For we must not confuse the intense suffering in and of itself with the good things to which it sometimes leads or of which it may be a necessary part. Intense human or animal suffering is in itself bad, an evil, even though it may sometimes be justified by virtue of being a part of, or leading to, some good which is unobtainable without it. What is evil in itself may sometimes be good as a means because it leads to something that is good in itself. In such a case, while remaining an evil in itself, the intense human or animal suffering is, nevertheless, an evil which someone might be morally justified in permitting.
Taking human and animal suffering as a clear instance of evil which occurs with great frequency in our world, the argument for atheism based on evil can be stated as follows:
1. There exist instances of intense suffering which an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some evil equally bad or worse.²
2. An omniscient, wholly good being would prevent the occurrence of any intense suffering it could, unless it could not do so without thereby losing some greater good or permitting some evil equally bad or worse.
3. There does not exist an omnipotent, omniscient, wholly good being.
What are we to say about this argument for atheism, an argument based on the profusion of one sort of evil in our world? The argument is valid; therefore, if we have rational grounds for accepting its premises, to that extent we have rational grounds for accepting atheism. Do we, however, have rational grounds for accepting the premises of this argument?
Let’s begin with the second premise. Let s1 be an instance of intense human or animal suffering which an omniscient, wholly good being could prevent. We will also suppose that things are such that s1 will occur unless prevented by the omniscient, wholly good (OG) being. We might be interested in determining what would be a sufficient condition of OG failing to prevent s1. But, for our purpose here, we need only try to state a necessary condition for OG failing to prevent s1. That condition, so it seems to me, is this:
Either (i) there is some greater good, G, such that G is obtainable by OG only if OG permits s1,³
or (ii) there is some greater good, G, such that G is obtainable by OG only if OG permits either s1 or some evil equally bad or worse,
or (iii) s1 is such that it is preventable by OG only if OG permits some evil equally bad or worse.
It is important to recognize that (iii) is not included in (i). For losing a good greater than s1 is not the same as permitting an evil greater than s1. And this is because the absence of a good state of affairs need not itself be an evil state of affairs. It is also important to recognize that s1 might be such that it is preventable by OG without losing G (so condition (i) is not satisfied) but also such that if OG did prevent it, G would be lost unless OG permitted some evil equal to or worse than s1. If this were so, it does not seem correct to require that OG prevent s1. Thus, condition (ii) takes into account an important possibility not encompassed in condition (i).
Is it true that if an omniscient, wholly good being permits the occurrence of some intense suffering it could have prevented, then either (i) or (ii) or (iii) obtains? It seems to me that it is true. But if it is true, then so is premise (2) of the argument for atheism. For that premise merely states in more compact form what we have suggested must be true if an omniscient, wholly good being fails to prevent some intense suffering it could prevent. Premise (2) says that an omniscient, wholly good being would prevent the occurrence of any intense suffering it could, unless it could not do so without thereby losing some greater good or permitting some evil equally bad or worse. This premise (or something not too distant from it) is, I think, held in common by many atheists and nontheists. Of course, there may be disagreement about whether something is good, and whether, if it is good, one would be morally justified in permitting some intense suffering to occur in order to obtain it. Someone might hold, for example, that no good is great enough to justify permitting an innocent child to suffer terribly.⁴ Again, someone might hold that the mere fact that a given good outweighs some suffering and would be lost if the suffering were prevented, is not a morally sufficient reason for permitting the suffering. But to hold either of these views is not to deny (2). For (2) claims only that if an omniscient, wholly good being permits intense suffering, then either there is some greater good that would have been lost, or some equally bad or worse evil that would have occurred, had the intense suffering been prevented. (2) does not purport to describe what might be a sufficient condition for an omniscient, wholly good being to permit intense suffering, only what is a necessary condition. So stated, (2) seems to express a belief that accords with our basic moral principles, principles shared by both theists and nontheists. If we are to fault the argument for atheism, therefore, it seems we must find some fault with its first premise.
Suppose in some distant forest lightning strikes a dead tree, resulting in a forest fire. In the fire a fawn is trapped, horribly burned, and lies in terrible agony for several days before death relieves its suffering. So far as we can see, the fawn’s intense suffering is pointless. For there does not appear to be any greater good such that the prevention of the fawn’s suffering would require either the loss of that good or the occurrence of an evil equally bad or worse. Nor does there seem to be any equally bad or worse evil so connected to the fawn’s suffering that it would have had to occur had the fawn’s suffering been prevented. Could an omnipotent, omniscient being have prevented the fawn’s apparently pointless suffering? The answer is obvious, as even the theist will insist. An omnipotent, omniscient being could have easily prevented the fawn from being horribly burned, or, given the burning, could have spared the fawn the intense suffering by quickly ending its life, rather than allowing the fawn to lie in terrible agony for several days. Since the fawn’s intense suffering was preventable and, so far as we can see, pointless, doesn’t it appear that premise (1) of the argument is true, that there do exist instances of intense suffering which an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some evil equally bad or worse.
It must be acknowledged that the case of the fawn’s apparently pointless suffering does not prove that (1) is true. For even though we cannot see how the fawn’s suffering is required to obtain some greater good (or to prevent some equally bad or worse evil), it hardly follows that it is not so required. After all, we are often surprised by how things we thought to be unconnected turn out to be intimately connected. Perhaps, for all we know, there is some familiar good outweighing the fawn’s suffering to which that suffering is connected in a way we do not see. Furthermore, there may be unfamiliar goods, goods we haven’t dreamed of, to which the fawn’s suffering is inextricably connected. Indeed, it would seem to require something like omniscience on our part before we should lay claim to knowing that there is no greater good connected to the fawn’s suffering in such a manner than an omnipotent, omniscient being could not have achieved that good without permitting that suffering or some evil equally bad or worse. So the case of the fawn’s suffering surely does not enable us to establish the truth of (1).
The truth is that we are not in a position to prove that (1) is true. We cannot know with certainty that instances of suffering of the sort described in (1) do occur in our world. But it is one thing to know or prove that (1) is true and quite another thing to have rational grounds for believing (1) to be true. We are often in the position where in the light of our experience and knowledge it is rational to believe that a certain statement is true, even though we are not in a position to prove or to know with certainty that the statement is true. In the light of our past experience and knowledge it is, for example, very reasonable to believe that neither Goldwater nor McGovern will ever be elected President, but we are scarcely in the position of knowing with certainty that neither will ever be elected President. So, too, with (1), although we cannot know with certainty that it is true, it perhaps can be rationally supported, shown to be a rational belief.
Consider again the case of the fawn’s suffering. Is it reasonable to believe that there is some greater good so intimately connected to that suffering that even an omnipotent, omniscient being could not have obtained that good without permitting that suffering or some evil at least as bad? It certainly does not appear reasonable to believe this. Nor does it seem reasonable to believe that there is some evil at least as bad as the fawn’s suffering such that an omnipotent being simply could not have prevented it without permitting the fawn’s suffering. But even if it should somehow be reasonable to believe either of these things of the fawn’s suffering, we must then ask whether it is reasonable to believe either of these things of all the instances of seemingly pointless human and animal suffering that occur daily in our world. And surely the answer to this more general question must be no. It seems quite unlikely that all the instances of intense suffering occurring daily in our world are intimately related to the occurrence of a greater good or the prevention of evils at least as bad: and even more unlikely, should they somehow all be so related, that an omnipotent, omniscient being could not have achieved at least some of those goods (or prevented some of those evils) without permitting the instances of intense suffering that are supposedly related to them. In the light of our experience and knowledge of the variety and scale of human and animal suffering in our world, the idea that none of this suffering could have been prevented by an omnipotent being without thereby losing a greater good or permitting an evil at least as bad seems an extraordinarily absurd idea, quite beyond our belief. It seems then that although we cannot prove that (1) is true, it is, nevertheless, altogether reasonable to believe that (1) is true, that (1) is a rational belief.⁵
Returning now to our argument for atheism, we’ve seen that the second premise expresses a basic belief common to many theists and nontheists. We’ve also seen that our experience and knowledge of the variety and profusion of suffering in our world provides rational support for the first premise. Seeing that the conclusion, There does not exist an omnipotent, omniscient, wholly good being,
follows from these two premises, it does seem that we have rational support for atheism, that it is reasonable for us to believe that the theistic God does not exist.
II
Can theism be rationally defended against the argument for atheism we have just examined? If it can, how might the theist best respond to that argument? Since the argument from (1) and (2) to (3) is valid, and since the theist, no less than the nontheist, is more than likely committed to (2), it’s clear that the theist can reject this atheistic argument only by rejecting its first premise, the premise that there are instances of intense suffering which an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some evil equally bad or worse. How, then, can the theist best respond to this premise and the considerations advanced in its support?
There are basically three responses a theist can make. First, he might argue not that (1) is false or probably false, but only that the reasoning given in support of it is in some way defective. He may do this either by arguing that the reasons given in support of (1) are in themselves insufficient to justify accepting (1), or by arguing that there are other things we know which, when taken in conjunction with these reasons, do not justify us in accepting (1). I suppose some theists would be content with this rather modest response to the basic argument for atheism. But given the validity of the basic argument and the theist’s likely acceptance of (2), he is thereby committed to the view that (1) is false, not just that we have no good reasons for accepting (1) as true. The second two responses are aimed at showing that it is reasonable to believe that (1) is false. Since the theist is committed to this view, I shall focus the discussion on these two attempts, attempts which we can distinguish as the direct attack
and the indirect attack.
By a direct attack, I mean an attempt to reject (1) by pointing out goods, for example, to which suffering may well be connected, goods which an omnipotent, omniscient being could not achieve without permitting suffering. It is doubtful, however, that the direct attack can succeed. The theist may point out that some suffering leads to moral and spiritual development impossible without suffering. But it’s reasonably clear that suffering often occurs in a degree far beyond what is required for character development. The theist may say that some suffering results from free choices of human beings and might be preventable only by preventing some measure of human freedom. But, again, it’s clear that much intense suffering occurs not as a result of human free choices. The general difficulty with this direct attack on premise (1) is twofold. First, it cannot succeed, for the theist does not know what greater goods might be served, or evils prevented, by each instance of intense human or animal suffering. Second, the theist’s own religious tradition usually maintains that in this life it is not given to us to know God’s purpose in allowing particular instances of suffering. Hence, the direct attack against premise (1) cannot succeed and violates basic beliefs associated with theism.
The best procedure for the theist to follow in rejecting premise (1) is the indirect procedure. This procedure I shall call the G. E. Moore shift,
so called in honor of the twentieth-century philosopher, G. E. Moore, who used it to great effect in dealing with the arguments of the skeptics. Skeptical philosophers such as David Hume have advanced ingenious arguments to prove that no one can know of the existence of any material object. The premises of their arguments employ plausible principles, principles which many philosophers have tried to reject directly, but only with questionable success. Moore’s procedure was altogether different. Instead of arguing directly against the premises of the skeptic’s arguments, he simply noted that the premises implied, for example, that he (Moore) did not know of the existence of a pencil. Moore then proceeded indirectly against the skeptic’s premises by arguing:
I do know that this pencil exists.
If the skeptic’s principles are correct I cannot know the existence of this pencil.
Therefore,
∴The skeptic’s principles (at least one) must be incorrect.
Moore then noted that his argument is just as valid as the skeptic’s, that both of their arguments contain the premise If the skeptic’s principles are correct Moore cannot know of the existence of this pencil,
and concluded that the only way to choose between the two arguments (Moore’s and the skeptic’s) is by deciding which of the first premises it is more rational to believe—Moore’s premise, I do know that this pencil exists,
or the skeptic’s premise asserting that his skeptical principles are correct. Moore concluded that his own first premise was the more rational of the two.⁶
Before we see how the theist may apply the G. E. Moore shift to the basic argument for atheism, we should note the general strategy of the shift. We’re given an argument: p, q, therefore, r. Instead of arguing directly against p, another argument is constructed—not-r, q, therefore, not-p—which begins with the denial of the conclusion of the first argument, keeps its second premise, and ends with the denial of the first premise as its conclusion. Compare, for example, these two:
It is a truth of logic that if I is valid, II must be valid as well. Since the arguments are the same so far as the second premise is concerned, any choice between them must concern their respective first premises. To argue against the first premise (p) by constructing the counterargument II is to employ the G. E. Moore shift.
Applying the G. E. Moore shift against the first premise of the basic argument for atheism, the theist can argue as follows:
not-3. There exists an omnipotent, omniscient, wholly good being.
2. An omniscient, wholly good being would prevent the occurrence of any intense suffering it could, unless it could not do so without thereby losing some greater good or permitting some evil equally bad or worse. Therefore,
not-1. It is not the case that there exist instances of intense suffering which an omnipotent, omniscient being could have prevented without thereby losing some greater good or permitting some evil equally bad or worse.
We now have two arguments: the basic argument for atheism from (1) and (2) to (3), and the theist’s best response, the argument from (not-3) and (2) to (not-1). What the theist then says about (1) is that he has rational grounds for believing in the existence of the theistic God (not-3), accepts (2) as true, and sees that (not-1) follows from (not-3) and (2). He concludes, therefore, that he has rational grounds for rejecting (1). Having rational grounds for rejecting (1), the theist concludes that the basic argument for atheism is mistaken.
III
We’ve had a look at a forceful argument for atheism and what seems to be the theist’s best response to that argument. If one is persuaded by the argument for atheism, as I find myself to be, how might one best view the position of the theist? Of course, he will view the theist as having a false belief, just as the theist will view the atheist as having a false belief. But what position should the atheist take concerning the rationality of the theist’s belief? There are three major positions an atheist might take, positions which we may think of as some varieties of atheism. First, the atheist may believe that no one is rationally justified in believing that the theistic God exists. Let us call this position unfriendly atheism.
Second, the atheist may hold no belief concerning whether any theist is or isn’t rationally justified in believing that the theistic God exists. Let us call this view indifferent atheism.
Finally, the atheist may believe that some theists are rationally justified in believing that the theistic God exists. This view we shall call friendly atheism.
In this final part of the paper I propose to discuss and defend the position of friendly atheism.
If no one can be rationally justified in believing a false proposition, then friendly atheism is a paradoxical if not incoherent position. But surely the truth of a belief is not a necessary condition of someone’s being rationally justified in having that belief. So in holding that someone is rationally justified in believing that the theistic God exists, the friendly atheist is not committed to thinking that the theist has a true belief. What he is committed to is that the theist has rational grounds for his belief, a belief the atheist rejects and is convinced he is rationally justified in rejecting. But is this possible? Can someone, like our friendly atheist, hold a belief, be convinced that he is rationally justified in holding that belief, and yet believe that someone else is equally justified in believing the opposite? Surely this is possible. Suppose your friends see you off on a flight to Hawaii. Hours after take-off they learn that your plane has gone down at sea. After a twenty-four hour search, no survivors have been found. Under these circumstances they are rationally justified in believing that you have perished. But it is hardly rational for you to believe this, as you bob up and down in your life vest, wondering why the search planes have failed to spot you. Indeed, to amuse yourself while awaiting your fate, you might very well reflect on the fact that your friends are rationally justified in believing that you are now dead, a proposition you disbelieve and are rationally justified in disbelieving. So, too, perhaps an atheist may be rationally justified in his atheistic belief and yet hold that some theists are rationally justified in believing just the opposite of what he believes.
What sort of grounds might a theist have for believing that God exists? Well, he might endeavor to justify his belief by appealing to one or more of the traditional arguments: Ontological, Cosmological, Teleological, Moral, etc. Second, he might appeal to certain aspects of religious experience, perhaps even his own religious experience. Third, he might try to justify theism as a plausible theory in terms of which we can account for a variety of phenomena. Although an atheist must hold that the theistic God does not exist, can he not also believe, and be justified in so believing, that some of these justifications of theism
do actually rationally justify some theists in their belief that there exists a supremely good, omnipotent, omniscient being? It seems to me that he can.
If we think of the long history of theistic belief and the special situations in which people are sometimes placed, it is perhaps as absurd to think that no one was ever rationally justified in believing that the theistic God exists as it is to think that no one was ever justified in believing that human beings would never walk on the moon. But in suggesting that friendly atheism is preferable to unfriendly atheism, I don’t mean to rest the case on what some human beings might reasonably have believed in the eleventh or thirteenth century. The more interesting question is whether some people in modern society, people who are aware of the usual grounds for belief and disbelief and are acquainted to some degree with modern science, are yet rationally justified in accepting theism. Friendly atheism is a significant position only if it answers this question in the affirmative.
It is not difficult for an atheist to be friendly when he has reason to believe that the theist could not reasonably be expected to be acquainted with the grounds for disbelief that he (the atheist) possesses. For then the atheist may take the view that some theists are rationally justified in holding to theism but would not be so were they to be acquainted with the grounds for disbelief—those grounds being sufficient to tip the scale in favor of atheism when balanced against the reasons the theist has in support of his belief.
Friendly atheism becomes paradoxical, however, when the atheist contemplates believing that the theist has all the grounds for atheism that he, the atheist, has, and yet is rationally justified in maintaining his theistic belief. But even so excessively friendly a view as this perhaps can be held by the atheist if he also has some reason to think that the grounds for theism are not as telling as the theist is justified in taking them to be.⁷
In this paper I’ve presented what I take to be a strong argument for atheism, pointed out what I think is the theist’s best response to that argument, distinguished three positions an atheist might take concerning the rationality of theistic belief, and made some remarks in defense of the position called friendly atheism.
I’m aware that the central points of the paper
