The Probability Of God

Does God exist? This is probably the most debated question in the history of mankind. Scholars, scientists, and philosophers have spent their lifetimes trying to prove or disprove the existence of God, only to have their theories crucified by other scholars, scientists, and philosophers. Where the debate breaks down is in the ambiguities and colloquialisms of language. But, by using a universal, unambiguous language—namely, mathematics—can this question finally be answered definitively? That’s what Dr. Stephen Unwin attempts to do in this riveting, accessible, and witty book, The Probability of God. At its core, this groundbreaking book reveals how a math equation developed more than 200 years ago by noted European philosopher Thomas Bayes can be used to calculate the probability that God exists. The equation itself is much more complicated than a simple coin toss (heads, He’s up there running the show; tails, He’s not). Yet Dr. Unwin writes with a clarity that makes his mathematical proof easy for even the nonmathematician to understand and a verve that makes his book a delight to read. Leading you carefully through each step in his argument, he demonstrates in the end that God does indeed exist. Whether you’re a devout believer and agree with Dr. Unwin’s proof or are unsure about all things divine, you will find this provocative book enlightening and engaging.

What if all events—big and small, good and bad—are governed by more than just blind chance? What if they are governed by God? In this theologically informed and philosophically nuanced introduction to the study of probability and chance, Vern Poythress argues that all events—including the seemingly random or accidental—fall under God’s watchful gaze and are part of his eternal plan. Poythress tackles questions related to everything from natural disasters to the roll of the dice, explaining how God’s sovereignty functions as the lens through which we study subjects such as science, mathematics, modern physics, evolutionary biology, human choice, and gambling. Comprehensive in its scope, this book lays the theistic foundation for our scientific assumptions about the world while addressing personal questions about the meaning and significance of everyday events.

In recent years, a number of works have appeared with important implications for the age-old question of the existence of a god. These writings, many of which are not by theologians, strengthen the rational case for the existence of a god, even as this god may not be exactly the Christian God of history. This book brings together for the first time such recent diverse contributions from fields such as physics, the philosophy of human consciousness, evolutionary biology, mathematics, the history of religion, and theology. Based on such new materials as well as older ones from the twentieth century, it develops five rational arguments that point strongly to the (very probable) existence of a god. They do not make use of the scientific method, which is inapplicable to the question of a god. Rather, they are in an older tradition of rational argument dating back at least to the ancient Greeks. For those who are already believers, the book will offer additional rational reasons that may strengthen their belief. Those who do not believe in the existence of a god at present will encounter new rational arguments that may cause them to reconsider their opinion.

The central question I pose in this book is: If there existed a supe rior being who possessed the supernatural qualities of omni science, omnipotence, immortality, and incomprehensibility, how would he/she act differently from us, and would these differences be knowable? (ßecause God, the superior being in the Judeo Christian tradition, is generally described as a male, I shall hence forth use the masculine pronoun form for convenience, but I intend no invidious gender distinctions, whether applied to super natural or natural beings.l Theologians, philosophers of religion, and erudite scholars in other disciplines have addressed this and related questions before, but their answers, generally speaking, have not been informed by any systematic or rigorous theory. I believe the mathematical theory of games, which has little to do with the frivolity and playfulness we normally associate with games, provides a powerful tool for clarifying the key theo logical concepts in my central question and drawing out their implications in games played between human and superior beings. I am fully aware that not everybody will agree that omni science, omnipotence, immortality, and incomprehensibility are what I say they are, but I invite them to propose their own defi- Preface viii nitions and derive their own conclusions with the aid of the theory. By endowing these protean concepts with unambiguous meanings, I will try to show how game theory can breathe life into questions that have been dismissed too quickly simply because they are metaphysical-outside the world of experience.

Is There a God? offers a powerful response to modern doubts about the existence of God. It may seem today that the answers to all fundamental questions lie in the province of science, and that the scientific advances of the twentieth century leave little room for God. Cosmologists have rolled back their theories to the moment of the Big Bang, the discovery of DNA reveals the key to life, the theory of evolution explains the development of life... and with each new discoveryor development, it seems that we are closer to a complete understanding of how things are. For many people, this gives strength to the belief that God is not needed to explain the universe; that religious belief is not based on reason; and that the existence of God is, intellectually, a lost cause.Richard Swinburne, one of the most distinguished philosophers of religion of our day, argues that on the contrary, science provides good grounds for belief in God. Why is there a universe at all ? Why is there any life on Earth? How is it that discoverable scientific laws operate in the universe? Professor Swinburne uses the methods of scientific reasoning to argue that the best answers to these questions are given by the existence of God. The picture of the universe that science gives us iscompleted by God.This new, updated edition of Richard Swinburne's popular introductory book Is There a God? features two substantial changes. He presents a new, stronger argument why theism does and materialism does not provide a very simple ultimate explanation of the world. And he examines the idea of the possible existence of many other universes, and its relevance to his arguments from the fine-tuning of our universe to the existence of God.

The renowned science writer, mathematician, and bestselling author of Fermat's Last Theorem masterfully refutes the overreaching claims the "New Atheists," providing millions of educated believers with a clear, engaging explanation of what science really says, how there's still much space for the Divine in the universe, and why faith in both God and empirical science are not mutually exclusive. A highly publicized coterie of scientists and thinkers, including Richard Dawkins, the late Christopher Hitchens, and Lawrence Krauss, have vehemently contended that breakthroughs in modern science have disproven the existence of God, asserting that we must accept that the creation of the universe came out of nothing, that religion is evil, that evolution fully explains the dazzling complexity of life, and more. In this much-needed book, science journalist Amir Aczel profoundly disagrees and conclusively demonstrates that science has not, as yet, provided any definitive proof refuting the existence of God. Why Science Does Not Disprove God is his brilliant and incisive analyses of the theories and findings of such titans as Albert Einstein, Roger Penrose, Alan Guth, and Charles Darwin, all of whose major breakthroughs leave open the possibility— and even the strong likelihood—of a Creator. Bolstering his argument, Aczel lucidly discourses on arcane aspects of physics to reveal how quantum theory, the anthropic principle, the fine-tuned dance of protons and quarks, the existence of anti-matter and the theory of parallel universes, also fail to disprove God.
