The Problem of Evil
Last time we considered the ontological argument for the existence of God. If the argument is cogent, then we have reason
to be rational theists, i.e., to maintain that there are justifying reasons for belief in God's existence. Today we're going to
consider an argument for atheism which purports to show that theism is incoherent, i.e., that theism entails a contradiction.
If the argument works, then the only option available to the theist would be irrational theism: belief in God's existence in
spite of justifying reasons supporting atheism.
I. Contradictions
Not having a good argument in support of something you believe is uncomfortable, but we live with this condition all the
time. Sometimes our beliefs are a matter of wishful thinking; when there is no compelling evidence one way or the other,
we just make the best guess we can. What is more difficult to live with is having a convincing argument against your
belief, for this commits you to a contradiction.
What is a contradiction and why is it more problematic than just believing without conclusive evidence? A set of beliefs is
contradictory if and only if it is not possible for all of them to be true together, that is, if at least one of them must be false.
Consider a simple example:
a) All birds can fly.
b) Penguins are birds.
c) Penguins can't fly.
Not all of (a-c) can be true together (one must be false). To recognize this and still believe all three (say, on faith) would
not just be a matter of believing something without reason (like believing without evidence that your parents will send you
more money at the end of the month); if you persist in believing all of (a-c) you can be sure that that you are accepting at
least one falsehood. It's similar to maintaining both that today is Wednesday and that it is not the case that today is
Wednesday. Not both of those can be true: to believe both is to believe something impossible is the case. That would be
irrational.
II. The Problem of Evil
Remember, we're considering the existence of a certain kind of God, a God who is perfect in every way. By hypothesis,
this God is omniscient, omnipotent, and wholly good (I'll abbreviate these characteristics as "OOG").
1) If God exists, she'd be OOG. [By hypothesis]
Now surely if an OOG God exists, there ought to be no evil in the world. Here's why: Since God knows everything, she
knows when there is going to be an earthquake, or terrorist attack, or a lynching. Since she is all-powerful, she could
prevent it if she tried. But since she is wholly good, she does try. Thus the earthquake, terrorist attack, lynching, etc. is
prevented. So:
2) If an OOG being exists, there would be no evil. [from 1]
Suppose, then, that:
3) God exists.
You should conclude that:
4) There is no evil. [From 1-3]
But the truth is that (as the Dostoevsky reading and current events make vividly clear):
5) There is evil.
But note that (4) and (5) are contradictory. You can't reasonably believe both that there is and there is not evil in the world.
As a result, even many religious people have felt compelled to conclude:
6) [An OOG] God does not exist.
This is the problem of evil for theism. Unless there is a way around the problem, theists have reason to give up their belief,
on pain of irrationality.
Note that the argument, as presented, has the form of a reductio ad absurdum. A reductio is an argument which begins by
assuming a claim that is in question--we can call this the target claim--and demonstrates that it entails a contradiction.
Because we have reason to avoid contradiction, the fact that it entails a contradiction casts doubt on the target claim.
However, usually the target claim only entails a contradiction when combined with other (often implicit) assumptions. So
it is open to critics to make the additional assumptions explicit and call them into question instead.
For example, as Mackie points out (p. 100), questionable assumptions implicit in the argument just outlined, include:
1a) A good thing always eliminates evil as far as it can.
1b) There are no limits to what an omnipotent thing can do.
(One might also reject an explicit assumption in the argument, viz., (5) there is evil. But this last strategy is not easy to
sustain in the face of the pain and suffering around us.)
III. Objections
A. Evil is necessary as a counterpart to good; without at least some evil there could be no good.
Problems:
i. This seems to impose some limits on God's power.
ii. Is evil really necessary for there to be good?
iii. Even if the principle is correct, we only need a little bit of evil to provide the required contrast with good, so why all
the horrors?
Re i: Taken literally (A) looks like itís limiting Godís power. For if there canít be good without evil, then God canít make
good without evil, so God isnít omnipotent.
But this is too quick. Omnipotence can't mean the ability to do even what is strictly impossible. God can turn Lotís wife
into a pillar of salt, maybe, but he canít both turn her into a pillar of salt and at the same time not do so. And surely this
implies no limitation on his powers: in saying that God is omnipotent, we weren't saying that God could do what's
logically impossible..
Re ii: Is it really impossible for there to be good without evil? To get clear on this we have to distinguish two quite
different ways we have of describing things; we have to distinguish comparative descriptions from non-comparative.
Examples of comparative descriptions are words like "small"/"large", "easy"/ "difficult", "empty"/"crowded." These are
called "comparative" because to be small is to be smaller than most other things.. So as a rough test we might say:
BLAH is a comparative description if & only if to be BLAH is to be more BLAH than the competition.
A description is non-comparative if it's not comparative. Examples of non-comparative descriptions are words like
"chipmunk" or "square." Something is a chipmunk not because it is chipmunkier than other things, but because of what it
is like in itself.
Now, what sorts of descriptions are "good" and "evil"? It might appear that they are comparative. Then it would seem to
follow that there canít be a world in which everything was good -- no more than there can be one in which everything was
small!
Have we blocked Mackie's argument then? Premise (2) now looks false. An OOG God would not bring about a world that
was wholly good, because given the relativity of goodness such a world is impossible. The trouble is that the idea that
good things are things that are better than most other things is not plausible. Most of us think that, say, honesty, is good.
But do we think that honesty would become bad if still higher goods, say charity, became prevalent? Or consider: I do
something "bad," e.g., steal something from my brother. But all is not lost on the view we're considering, for by arranging
for a lot of still worse things too happen, I can make it "good"! Would causing pain turn good if everyone else was causing
more pain? It doesn't seem so.
It is plausible that often we do use "good" and "bad" comparatively. But all the objection needs is that there is a sense or
context in which "good" and "bad" are non-comparative. Compare grading on a curve to grading by a uniform standard.
Doesn't it make sense when someone gets a 100% on an exam that the exam answers were good, and not just better than
the rest of the class? (After all, it is possible on a uniform standard for everyone to get an A, i.e., for everyone to do a good
job.) If "good" and "evil" can be used non-comparatively, then it isn't true that good logically requires evil.
Re iii: Even if one maintains that good/bad are comparative notions, in order for there to be a basis for comparison, the
world would only need to contain a small amount of evil (the good things are all better than that!. But this world clearly
contains more than the alleged logically necessary amount of evil.
B. Evil is necessary as a means to good.
C. Evil is a necessary precondition of certain goods
Or as Mackie puts it, "the world is better with some evil in it than it could be if there were no evil." The idea is that if there
were certain very special and important goods that depended on the existence of evil, then in order for God to create the
best world, there must be some evil. (Note: there could be good without evil, but not best without evil.)
So the idea is that certain goods presuppose or demand the existence of evil. Which ones? Pleasure, excitement,
satisfaction: these things don't presuppose evil. But then, these things, while very nice, don't seem like the best we as
humans are capable of. Sympathy, charity, heroism, kindness, all seem to depend for their very possibility on the existence
of evil. There can be no sympathy if no one is suffering, or heroism is there is no danger. Yet sympathy, heroism, etc. are
much more important goods than mere animal pleasure. So naturally God will put a little pain and misery in the world so
as to create the possibility of these higher goods. By doing this he makes the world better overall than it would be if he left
them out.
So, the view is that God creates first-order evil only to set the stage for a second-order good which more than offsets it; we
might say that first-order evil is redeemed by the second-order good that it makes possible. So, deprivation is redeemed by
the kindness it makes possible. Of course, this leaves it unexplained why there is also second order evil, e.g., mockery.
&nbs p; goods &nb sp; evils
3rd order: f orgiveness/piety &nbs p; cynicism
2nd order: compassion/heroism mockery/cruelty
1st order: &n bsp; laughter/pleasure &nb sp; deprivation/starvation/pain
Can you see how the theist is going to answer? He can try to run the same argument at a higher level: this second order
evil is only there in the service of some third order good which more than offsets it.
Overall the picture is that there are different orders of good and evil. First order good is happiness, pleasure, and the like;
first order evil is pain, misery, and so on. Second order good is good that presupposes first order evil; and second order
evil is evil that presupposes first order good. Likewise, third order good presupposes second order evil, etc. So, hunger
might be a first order evil and laughing a first order good; charity a second order good and mockery a second order evil;
cynicism a third order evil and forgiveness a third order good; and so on. And in general nth order evil exists only to make
possible an (n+1)st order good that offsets it and makes the world overall better.
But this sets up the final point: how can it be maintained that the world contains just that amount of nth order evil requisite
for the corresponding (n+1)st order good? In fact this is almost never the case. Sad but true, people grown old and die
desperate and broken-hearted without anyone showing them the kindness that might conceivability redeem their pain. All
in all, it appears that there is far more nth order evil than could be justified in terms of higher order goods.
D. Evil is due not to God but to human free will.
This is probably the most important response to the problem of evil, and it is connected to (C). The question arises, why
did God grant us free will if so much misery results? And the answer must be that it is better on the whole that people
should act freely even granted the disastrous use we sometimes make of our freedom. Free will is a higher good that more
than makes up for whatever trouble it causes.
Problems:
i) Lots of evils arenít related to free will at all: earthquakes, floods, etc. Why do these exist if God is good? (Punishment?
Instruction? But what about the death of innocents?
ii) Why couldnít God have given us such excellent characters that we would freely choose good in every case? Perhaps, we
would always have the option of doing evil, but we would always prefer the other option. As Mackie puts it: God was not
faced with the choice of making either automata or free agents who sometimes go wrong. She could also have made free
agents that always go right! (Analogy: most of us choose to stay on the sidewalk rather than to dart out into traffic; this is
predictable but it doesnít mean we arenít free.) The fact that I have the character I do is not a barrier to my freedom, even
if I didnít choose my character. But then why didnít god make us all with wonderful good characters? Is Mother Theresa
unfree? Why couldn't we all be like her?
iii) Free will seems incompatible with Godís omnipotence. The reason is that when God gives me free will, she commits
herself to letting my actions depend on my decisions rather than hers. So, if I decide to steal a car, or burn a flag, because
of her commitment God cannot stop me!!!! And if God cannot stop me, then that would seem to imply a limitation on her
powers.
QUESTIONS TO THINK ABOUT:
? What is the best possible world like? Is ours it? What, if anything, does it lack?
? If ours is not the best possible world, is it possible for there nonetheless to be an OOG God?
? How much pain is legitimized by higher goods? Is all the pain and suffering we see around us really necessary for the
world to be the best place it could be?
? What is really required in order to give humans freewill? Could we be predisposed to be good and still be free? Could we
have perfect characters and still be free? Why did God create some of us with bad characters, i.e., with predispositions to
do evil?
? How does a theist accommodate the fact of natural disasters and the pain and suffering they cause?
