First off, an admission: Plantinga's
God, Freedom, and Evil isn't as bad as I remembered. I enjoyed his discussion of possible worlds, and found his logic compelling--at least, for one version of theism (see below), although it rests on undefended suppositions (again, see below). Second, the logical argument from evil is on life support. In one of his contributory essays in
The Evidential Argument From Evil, William Alston writes, "It is now acknowledged on (almost) all sides that the logical argument is bankrupt (p. 285). Richard Gale, though, disagrees: "In my book,
On the Nature and Existence of God, I argued that no version of [the free will defense] works, and thereby the logical problem posed by moral evil is still with us" (p. 206). (I have
another book to add to my reading list.)
Third, a caveat: this essay is a work in progress, and also quite long for a
decorabilia post*. Feel free to comment; it will not appear in final form until I've sharpened my arguments and read a lot more. And, given my voracious reading habits, that may not be until some time long into the future.
So, to the issue.
In the central argument of the book, Plantinga adds up the premises which (as far has he can tell) are the only way to find a contradiction between the existence of God and the continuance of evil. They are:
(1) God is omnipotent, omniscient, and wholly good.
(2) Evil exists [more precisely, "evil states of affairs exist"]
(3) There are no nonlogical limits to what an omnipotent being can do
(4) An omniscient and omnipotent good being eliminates every evil it can properly eliminate, ergo
(5) If God is omnipotent and omniscient, He can properly eliminate every evil state of affairs
Plantinga posits that these statements entail no contradiction in the light of human free will: "To create creatures capable of
moral good, therefore, He must create creatures capable of moral evil; and He can't give these creatures the freedom to perform evil and at the same time prevent them from doing so" (p. 30).
Notice that (4) is framed positively, ignoring a different slant on the argument. If, as Plantinga has claimed elsewhere, God is involved in every action in creation, "from the Big Bang to the sparrow's fall," does that not change the argument? Now a "good being" is not only not eliminating evil, but actively perpetrating and sustaining it. While a God who lets the universe (mostly) run on its own can sidestep the blame for evil's persistence, in the world of "serious theism," God is "actively and intimately involved" in it. Therefore, a "natural atheologist" would frame (4) as "An omniscient and omnipotent good being does not perpetrate or sustain evil." Broadly speaking, the logical "problem of evil" is a problem only for the serious theist.
Furthermore, Plantinga declares (5) impossible, because eliminating evil state
E would necessarily eliminate good state
G, which outweighs and depends on
E's existence. His example is that of courage, a moral good that not only outweighs the evil it strives against, but could not exist without it. "It is a necessary truth that if someone bears pain magnificently, then someone is in pain" (p. 23).
However, there are many kinds of good which do
not depend on any sort of evil for their existence--generosity, creativity, kindness, patience, and so forth. Perhaps God could have created a world in which only those sorts of good existed.
Furthermore, God could also have created a world in which morally significant action was possible--stealing, for example--but humans were limited, physically, in their ability to wreak havoc. (Imagine skin that doesn't so easily puncture, tear, and bleed; imagine a brain packed in a thicker skull; imagine a genetic inheritance that makes people all about the same height and weight.) Plantinga claims that God couldn't have done these things for some unknown (and, ultimately, unknowable) reason. Furthermore, Plantinga wonders if there are transactions between spiritual beings we know nothing of--like the frame story in
Job, where God settles a wager with Satan by torturing his faithful servant. In short, defenses against this evidentiary argument from evil rely on ineffable, inscrutable reasons and unobservable, immeasurable entities. All well and good for the person of faith; hardly convincing to the skeptic.
Let us look deeper, though.
To accept Plantinga's Free Will Defense, we must accept two concepts: real (not just apparent) human freedom, and transworld depravity. The first goes assumed by Plantinga; the second is declared "possible," though it seems entirely
ad hoc, contrived for the purpose of showing how God
might be unable to actuate a world that includes morally free creatures who always choose rightly. So, Plantinga's argument shows that it is
possible that there is no logical inconsistency; it does
not show that such is obviously or necessarily true.
What sort of freedom (leaving aside such issues as predestination, foreknowledge, and the like) does Plantinga assume?
If a person is free with respect to a given action, then he is free to perform that action and free to refrain from performing it; no antecedent conditions and / or causal laws determine that he will perform the action, or that he won't.... Freedom so conceived is not to be confused with unpredictability. You might be able to predict what you will do in a given situation even if you are free, in that situation, to do something else (pp. 29-30).
Note that this sort of freedom lacks explanatory power, and is likely wrong, since it entirely removes human choice from the sphere of cause and effect--and, in doing so, makes humans into little Gods, able to effect uncaused actions.
Even if we grant that truly free will exists, though, we must ask: if free will is inviolable, yet humans, thanks to transworld depravity, are continually prone to abuse it, how is heaven, a place free of pain, suffering and sin, logically possible?
Furthermore, if God is both morally good and sinless, and (presumably) the most "valuable" being in all possible worlds (since He is the object of reverence and worship), did He create beings greater than himself with respect to moral freedom? Remember, Plantinga claims that transworld depravity precludes an actual world where free beings always choose the good. There is but one way to exclude God from this without declaring His nonexistence: by removing God's moral freedom. To recap: if God freely always does the right thing, Plantinga's argument implodes. If God has freely chosen the wrong thing, He is not wholly good. If God cannot help but always do the right thing, then humans are more "valuable" than God.
Again, Plantinga assumes--as do most Free Will Defenders--that free will is "valuable". From a human perspective, perhaps this is true. But from God's? If Plantinga's possible world scenario is correct, then God cannot actualize a world without depending on the undetermined choices of human (and other?) free agents. No wonder theistic worldviews are often apocalyptic. The Director's instructions go unheeded. In corners of the set, flats have been torn down. In others, self-styled
artistes tack on shambling additions. Prima donnas extemporize their lines, affect stupid accents, shout down other characters. Yet, thanks to vaunted Free Will, "the show must go on," until the Director, no longer able to contain a few millennia's worth of festering fury, burns down the stage, sweeping up a few chosen actors and leaving the rest to perish in flames.
There's much more I could say, but won't; this post is long enough. Take a serious look at
The Evidential Argument From Evil, though, if you want a much more in-depth discussion.
*And here are all the other tangential musings I would have included:
For all the value assigned to Free Will in theodicies, it seems to bear much less importance in theologies. Submission to the will of God is paramount; paradise is paradise due to the utter absence of contrarians.
What would the world look like if humans operated on moral principles derived from God's conduct?
I can imagine a possible world in which one free creature (call him Adam) exists, surrounded by unfree beings. (In fact, this is nothing more than the original creation story in Genesis, in classic Christian understanding.) My deity, though, goes one better than Yahweh. When Adam becomes distressed and bored after a day of doling out names to koalas and mantises, he complains to God; the deity, rather than creating Eve (and all the attendant problems to follow), decides to wipe Adam's memory clean as he sleeps. Adam wakes up to a new world with all its glorious possibilities. His free will has not been tampered with, and evil is nowhere in sight.
In a strange inversion of value, a world of full sinless automatons (devoid of evil) is worth
less than a world full of evil, sinful humans; however, a heaven scattered with a few saved souls is worth
more than a hell full of the lost.
And now, for the kicker. Epistemologically, how would it be possible to tell the difference between a world of clever automatons and a world of "free" beings, without resort to tautology?
