Alvin Plantinga: the 20th century's greatest philosopher?

Alvin Plantinga is arguably the greatest philosopher of the last century.
The Dutch-American Calvinist raised in the Midwest and now the John A. O'Brien Professor of Philosophy at the University of Notre Dame is not just the best Christian philosopher of his time. No, Plantinga is the most important philosopher of any stripe.
Plantinga deserves this accolade for three reasons.
First, he has taken up the two most important questions of our day: the problem of evil (arguably the most important philosophical question of any era) and the problem of knowledge (undoubtedly the key philosophical question of our era).
Second, he has made fundamental contributions to these two questions. On the problem of evil, Plantinga's vaunted "Free Will Defense" (to which we'll return in a moment) responded to the most trenchant form of this problem with a success rarely found in philosophy: for almost 20 years now, the discussion of the problem has shifted to other grounds because of the widespread acknowledgment of Plantinga's argument. In the case of epistemology (the theory of knowledge), his proposal is so recent that we must wait to see how it will fare. Indeed, the third volume of his epistemological trilogy on "warrant" was published only last year (Warranted Christian Belief, Oxford University Press). So far, however, it seems to have met all of its contemporary challenges.
Third, Plantinga has dealt with these two crucial issues on behalf of orthodox Christian faith. Because of the excellence of his labors, the Christian view of things simply has to be taken seriously by any questioner with the integrity to appreciate sound philosophy. Plantinga's greatness, then, lies also in his working on behalf of the truth—an admittedly biased judgment one surely need not defend in the pages of Christianity Today.
Wrestling with the Problem of Evil
In the so-called Free Will Defense, Plantinga answered the logical problem of evil, an apparently lethal argument that boldly claims theists cannot simultaneously affirm three propositions: that God is good, that God is all-powerful, and that evil exists. Therefore, says the argument, theism is incoherent, and one can thus dispense with it.
Plantinga's response is complicated—the shortest published version (God, Freedom, and Evil, Eerdmans, 1974) ran to more than 60 pages—but it essentially was this: God desired to love and be loved by other beings. God created human beings with this end in view. To make us capable of such fellowship, God had to give us the freedom to choose, since love cannot be either automatic or coerced. This sort of free will, however, entailed the danger that we would use it to go our own way in defiance of both God and our own best interests.
For God to grant human beings free will was to grant us the awful dignity of making real choices with real consequences. If God prevents us from sinning, he is preventing us from truly free action. And if God constantly and instantly repairs our mischief, then it is likely that we would never face our sin and need for redemption. (Then again, God could have looked ahead and seen which human beings would sin and which would choose well, and then actualized only the latter human beings; God thus would not have compromised human freedom but would also have allowed no evil to result from it.)
In any event, Plantinga suggests that perhaps we human beings suffer from what he calls "transworld depravity," a condition in which, no matter what the circumstances, each of us will commit at least one sin, and maybe many. We do so, that is, because it is somehow in each of our individual essences to do so. If God, for some reason (perhaps known only to God), wants to enjoy the fellowship of these particular beings (each with particular flaws), then God must let us be who we are, sin and all.
