Long at Ave Maria University some years ago. In that seminar, I spent most of my time taking careful notes! Steve has profound insight not only into Thomas Aquinas but also David Hume, Immanuel Kant, and Ludwig Wittgenstein, as all those privileged to take the seminar can attest. My chapter drafts were greatly improved by generous scholars who read portions of the manuscript on which they have expertise: Don Briel, Thomas Hibbs, Andrew Hofer, OP, Robert Koerpel, John Michael McDermott, SJ, Sean McGrath, Benjamin Myers, Kenneth Oakes, Kevin O’Reilly, OP, and Andrew Rosato. Michael Sirilla and Thomas Joseph White, OP, read the whole manuscript and saved me from many omissions and mistakes. I have incorporated a number of suggestions from all of these friends and colleagues. Francesca Murphy, Matthew Ramage, Emery de Gaál, Michael Sirilla, and Chad Pecknold testified to the viability of the project as a Baker Academic textbook. Bishop Robert Barron enthusiastically encouraged the project and inspired me by his own expertise on the topic. At Baker Academic, Dave Nelson supported the project from the outset, guided the book to publica tion, and offered wise counsel for improvement. Baker Academic’s Brian Bolger and the editorial staff did a superb job preparing the manuscript. My amazing research assistant, David Augustine, compiled the bibliogra phy and indexes and provided numerous corrections and suggestions that I incorporated into the text. I wrote this book for my children, in case it might ever be of use to them. May God, who in his infinite goodness is the meaning of life, give my beloved children eternal life in Christ Jesus. For my wife, Joy, my gratitude is so deep. ix Matthew Levering, Proofs of God Baker Academic, a division of Baker Publishing Group, © 2016. Used by permission.

Thomas Joseph White, OP. Of him it may be said, “The crown of the wise is their wisdom” (Prov. 14:24). God’s blessings be upon you, Fr. Thomas Joseph.

(Unpublished manuscript—copyright protected Baker Publishing Group) Introduction In this textbook, I offer a concise survey of the major responses, pro and contra, in the Christian tradition to the question of whether the existence of God can be demonstrated by human reason. Readers and classroom teachers should feel free to use the book selectively, rather than studying all of the twentyone figures I have chosen. My surveys of these twenty one figures aim to be accurate, concise, and thorough. For readers who are interested, I give my assessment of these figures in the conclusions to the three chapters. In the surveys themselves, I try to be descriptive rather than evaluative. In this introduction (as well as in the book’s conclusion), I offer my view of where things stand in contemporary intellectual discourse and popular culture regarding the topic of whether God’s existence can be demonstrated by human reason. In this introduction, I also give a rationale for choosing to study these twentyone figures, and I examine the key biblical and Hel lenistic ideas that set the terms for the demonstrations of God’s existence in the Christian tradition. To put my cards on the table, I think that the cosmos cannot be the source of its own existence. The cosmos is not a necessary being. In this regard, David Hart rightly remarks that “the contingent can only exist derivatively, receiving its existence from the Absolute.”1 When Stephen Hawking and Leonard Mlodinow claim that God’s existence is no longer plausible because 1. David Bentley Hart, The Experience of God: Being, Consciousness, Bliss (New Haven: Yale University Press, 2013), 147. Hart helps to correct misperceptions of what Ilia Delio, OSF, critically calls “the Greek architecture of metaphysics” (Delio, The Unbearable Wholeness of Being: God, Evolution, and the Power of Love [Maryknoll, NY: Orbis, 2013], xx). The misper ceptions are, unfortunately, apparent in Delio’s book. 1 Matthew Levering, Proofs of God Baker Academic, a division of Baker Publishing Group, © 2016. Used by permission.

Finite things exist, but they are merely limited modes of being; they are not being as such. A quantum law, insofar as it is, must derive its being from a source. Hawking and Mlodinow can be excused for their failure to grasp that the issue is “existence as such.” Their misunderstanding is shared by many professional philosophers. Thus, in his Arguing about Gods, Graham Oppy supposes himself to be undermining Thomas Aquinas’s five ways for dem onstrating God’s existence when he remarks that “it is hard to see that there is anything in Big Bang cosmology that rules out the existence of an infinite regress of changers, each changed by another.”3 Oppy’s point would not have bothered Aquinas at all, of course, since Aquinas allows philosophi cally for an eternal universe. In fact, none of Aquinas’s five ways depends on the universe having a temporal beginning. A similar mistake appears in Simon Blackburn’s Think: A Compelling Introduction to Philosophy. Blackburn devotes a chapter to God where he purports to engage Aquinas’s “cosmological argument.” But for his description of Aquinas’s argument, he rather oddly turns to Hume’s Dialogues concerning Natural Religion. The 2. Hart, Experience of God, 40. See Stephen Hawking and Leonard Mlodinow, The Grand Design (New York: Bantam, 2010). 3. Graham Oppy, Arguing about Gods (Cambridge: Cambridge University Press, 1999), 103. For his part, Anthony Kenny directs a set of arguments against Aquinas’s five ways, including the following claim: “If a thing cannot be moved by itself, it does not follow that it must be moved by something else. Why cannot it just be in motion, without being moved by anything, whether by itself or by anything else?” (Kenny, The Five Ways: St. Thomas Aquinas’ Proofs of God’s Existence [London: Routledge, 1969], 19). Seizing on Aquinas’s example from the transmission of heat, Kenny suggests that Aquinas depends here on outdated Aristotelian physics. Edward Feser has responded to Kenny in his Aquinas (Oxford: Oneworld, 2009), 67–69.
