The immortality of the soul is something of such vital importance to us, affecting us so deeply, that one must have lost all feeling not to care about knowing the facts of the matter. All our actions and thoughts must follow such different paths according to whether there is hope of eternal blessings or not, that the only possible way of acting with sense and judgment is to decide our course in light of this point, which ought to be our ultimate objective.
—Pascal1
This book deals with the most important questions you will ever think about, questions that every sane person must care about. You can deny that heaven and hell are real, but you cannot rationally be indifferent about the matter. Given what is at stake, the only sensible attitude is to care, and to care deeply.
The Christian doctrines of the afterlife have undoubtedly had an enormous impact on Western culture and have inspired everything from classic art and literature to the everyday hopes and fears of countless people. However, these doctrines have been under attack to one degree or another ever since the onset of the modern period, when a number of influential thinkers began to call them into question as part of a more general rejection of traditional religious belief.
In more recent times, many intellectuals, even theologians, have suggested that heaven is nothing more than a fading memory and that the flames of hell have flickered out. Just a few decades ago, in 1985, the noted religious historian Martin E. Marty published an article entitled “Hell Disappeared. No One Noticed. A Civic Argument.”2 One of the telling claims of his article was that he did a bibliographical search for recent material about hell but could find almost nothing. No one, it seemed, still believed in hell or thought much about it anymore. A few years later, in 1989, in an article in Newsweek, Harvard theologian Gordon Kaufman, citing what he saw as “irreversible changes,” declared, “I don’t think there can be any future for heaven and hell.”3
Just two years later, however, US News and World Report did a cover story entitled “Hell’s Sober Comeback” in which it reported a revival of belief in the doctrine, even among theologians. At the time, I had just written a dissertation defending the doctrine of hell for my PhD in philosophy at Notre Dame; that dissertation was published in 1992. The next year, two more books on hell were published by major university presses.4 Anyone who has been paying attention knows that hell has moved back to the front burner in the past few decades, and if Marty were doing a bibliographical search today, he would have no problem finding ample material.
Indeed, the doctrine of hell is a matter of intense debate at the current time, especially in evangelical Protestant circles. Some are defending traditional views of literal physical punishment, others are interpreting the torment of hell more metaphorically, and still others are arguing that the wicked will be annihilated rather than punished forever. More recently still, a number of theologians and philosophers have been arguing for universal salvation and denying that any are lost forever.5
A good measure of contemporary interest in these issues was the heated controversy that erupted over heaven and hell when Rob Bell’s 2011 book Love Wins was the subject of acrimonious internet warfare before it was even published.6 Rumor had it that Bell was advocating universalism, denying hell, and the like. So volatile was the controversy that the cover of Time magazine posed the question, “What If There’s No Hell?”7 Underneath the word “Hell” in large red letters, the cover read: “A popular pastor’s best-selling book has stirred fierce debate about sin, salvation, and judgment.”
Contrary to Marty’s claim, interest in hell never disappeared after all, and indeed, it appears to be back with a vengeance.
Nor has interest in heaven waned, contrary to Kaufman’s pronouncement in Newsweek. Indeed, Lisa Miller, for several years the religion editor of that magazine, published a book in 2010 with a title that takes on a certain ironic twist in light of Kaufman’s prediction, namely, Heaven: Our Enduring Fascination with the Afterlife. Miller notes that belief in the afterlife has been on the rise lately, with a 2007 Gallup poll indicating that 81 percent of Americans claimed to believe in heaven, up from 72 percent in 1997.8
Contemporary interest in the afterlife is also apparent in the extraordinary success of books about heaven written by people who have “died” or had near-death experiences in which they claimed to visit the heavenly realm. An enormously popular example is Heaven Is for Real: A Little Boy’s Astounding Story of His Trip to Heaven and Back,9 which was also made into a movie that was a box-office hit in 2014. As I write these lines, the most recent such bestseller is Proof of Heaven: A Neurosurgeon’s Journey into the Afterlife.10 Such books have the additional appeal of grounding the hope of the afterlife in empirical or scientific data. What they undeniably demonstrate, however, is our ongoing fascination with the glimpses (and in some cases extended visions) of the afterlife that they purport to provide.
But I want to emphasize that there is far more involved here than mere fascination. Indeed, fascination can be nothing more than curiosity at the unusual or the entertaining, the mysterious, and even the bizarre. Certainly, much that is written about heaven and hell is sensational and appeals to these tendencies. Moreover, popular writing about the afterlife is often sentimental, simplistic, and emotionally manipulative.
There is no doubt that some—perhaps much—of the continuing fascination with the afterlife is of the sensational and sentimental variety. It is the same sort of fascination some have with UFOs, ghost stories, and vampire romance novels.
But there is a much deeper reason we cannot look away, and that is simply because we have an enormous personal stake in these issues. Again, as I said at the outset, you cannot rationally be indifferent to heaven and hell. Blaise Pascal, the seventeenth-century philosopher, mathematician, and all-around genius, made this point with characteristically pointed passion in a number of passages, such as the one I quoted at the beginning of this introduction.11 As Pascal notes, there are vast and far-reaching consequences for both our thoughts and our actions, depending on whether our lives will end after several decades or go on forever. Simply put, the Christian doctrines of the afterlife involve a set of profoundly substantive truth claims with explosive implications.
I have been thinking about these extraordinary truth claims and their explosive implications throughout my academic career and, indeed, for several years before I ever went to graduate school to study philosophy. I was raised in a small, rural church in southern Ohio where the Christian version of the cosmic drama, complete with resurrection, final judgment, and heaven and hell, was passionately communicated in the preaching and teaching. Listening to the sermons at Bethel Chapel, one knew that matters of life and death and eternal happiness or misery were at stake in how one responded to the gospel.
All of this was called into question for me, however, when I went to Princeton Seminary to study theology. Not everyone I encountered there believed in the afterlife, let alone the traditional Christian account of it, and I particularly recall that the doctrine of hell was sharply challenged not only by some of the professors but by students as well. The clash between my religious upbringing and formation and my academic theological training was an existentially riveting one for me, and it forced me to think more deeply about these issues than I ever had before.
As I explored these matters more carefully, my conviction was confirmed that classical theology affirmed heaven and hell to be real in a way that resonated with my experience in my little country church. Moreover, given what was at stake in these doctrines, as well as their role in orthodox Christian teaching, it was clear to me that we must come to terms with them in one way or another.
Indeed, I think it is especially incumbent on all who profess orthodox Christianity to remain true to these remarkable doctrines and their far-reaching implications. I find it ironic that contemporary theologians sometimes wax eloquent about the radical nature of Christian theology or the truth of the Christian narrative but become mute or tentative when the issue of heaven is broached. The Christian story is extraordinary, to be sure, but it is radically incomplete and ultimately unsatisfying without a robust doctrine of the afterlife, and one simply cannot seriously affirm Trinity, incarnation, atonement, and resurrection without going on to heartily affirm “the life everlasting.”
In my own work as a philosopher of religion, I have been particularly concerned with exploring the rational credentials of these fascinating doctrines and examining the various philosophical issues they involve. I have not only argued that the philosophical challenges they face can be answered but, more positively, I have also contended that these doctrines are powerful resources for addressing some of the most fundamental issues that drive the philosophical enterprise. In particular, I believe these doctrines are most pertinent to such perennial issues as the problem of evil, the nature of personal identity, the foundations of morality, and, ultimately, the very meaning of life.
I have argued this in some detail in a trilogy beginning with my book on hell. I was not planning to write a trilogy at the time, but later reflection led me to see that just as hell poses a distinctive set of interesting issues, so does heaven. So I followed up Hell: The Logic of Damnation several years later with Heaven: The Logic of Eternal Joy. One of the issues I considered in that book was purgatory, and I devoted a chapter to that doctrine and thought I was done with it. Again, subsequent reflection led me to see that it too poses distinctive issues that deserve fuller exploration, and I was fortunate to receive a research fellowship in the Center for Philosophy of Religion at Notre Dame in 2009–10, where I wrote Purgatory: The Logic of Total Transformation.12 So by a sort of fitting poetic irony, I finished with purgatory where I had started with hell a couple of decades before.
In addition to this trilogy, I have written numerous essays on the afterlife as well as delivered many lectures and sermons on the subject. The present book is my attempt to distill my central thoughts on these issues in a more popular form than my academic books and essays. These issues matter to a far wider audience than professional philosophers and theologians, and I have aimed to communicate the heart of the issues in a way that will be fully accessible to all thoughtful readers who want to think about them more deeply. For those who want to think more deeply still, I urge you to follow up with my trilogy.
Before we proceed, I should say a word about the doctrine of purgatory, a doctrine that many readers will be surprised to see defended by a Protestant philosopher. At this point, I will only say that I am convinced not only that it makes biblical and theological sense but also that it helps us understand heaven, and perhaps hell, much better. Readers can judge whether they agree with me when they have finished the book, but I hope they will not judge before that.
Where to Begin?
As we proceed, an interesting question in its own right is where to begin. Dante’s famous masterpiece, the Divine Comedy, begins of course with hell, proceeds next to purgatory, and then concludes climactically with heaven. That makes perfect literary and dramatic sense. However, when we think about the matter theologically and philosophically, this may not be the best way to go. For some very profound reasons, hell can be best understood only in light of heaven. And the same is true of purgatory.
The point here is similar to what classic theologians have said about the nature of evil in relation to goodness. The essential point is that evil is not something that exists in its own right in the same way that goodness does. The fundamental reason for this is that God is perfectly good, and everything he created was originally good, even Satan.
Evil, then, must be defined in relation to goodness. As many classic theologians have put it, evil is a privation or a loss of the good. So evil things are good things that have become deformed in some way and thereby have gone bad. In other words, evil is a parasite that can only subsist on things that were originally good by way of corrupting them.
In a similar fashion, hell is to heaven as evil is to goodness. Heaven is the fundamental reality, and we cannot really understand hell unless we understand heaven first, just as we cannot grasp the idea of a fallen world unless we start with a world that is originally good.
As just noted, my own trilogy does not follow this order for reasons already given. I also started with hell and ended, somewhat ironically, with purgatory. But in this book, in which I will deal with all three regions of the afterlife, I shall begin where I think it makes best theological and philosophical sense to begin. When it comes to the things that matter most, heaven is clearly the place to start. So let us now turn our eyes in that direction.
