Yujin Nagasawa presents a new, stronger version of perfect being theism, the conception of God as the greatest possible being. Although perfect being theism is the most common form of monotheism in the Judeo-Christian-Islamic tradition its truth has been disputed by philosophers and theologians for centuries. Nagasawa proposes a new, game-changing defence of perfect being theism by developing what he calls the 'maximal concept of God'. Perfect being theists typically maintain that God is an omniscient, omnipotent, and omnibenevolent being; according to Nagasawa, God should be understood rather as a being that has the maximal consistent set of knowledge, power, and benevolence. Nagasawa argues that once we accept the maximal concept we can establish perfect being theism on two grounds. First, we can refute nearly all existing arguments against perfect being theism simultaneously. Second, we can construct a novel, strengthened version of the modal ontological argument for perfect being theism. Nagasawa concludes that the maximal concept grants us a unified defence of perfect being theism that is highly effective and economical.

This book examines the divine nature in terms of maximal greatness. It investigates each attribute associated with maximal greatness - omnipotence, omniscience, perfect goodness, eternity, and beauty, arguing that maximal greatness is necessary and sufficient for divinity.

The evil-god challenge is one of the most popular topics in contemporary philosophy of religion. In this landmark text, Jack Symes offers the most detailed examination of the challenge to date. Exploring the nature of god through the leading schools of philosophical theology, Symes argues that it is significantly more reasonable to attribute goodness to god than evil. Drawing from a breadth of ground-breaking material – in metaphysics, ethics, aesthetics and epistemology – Symes claims to defeat the evil-god challenge on behalf of traditional theism. Is it any more reasonable to believe in a good god than an evil god? Not according to proponents of the evil-god challenge. After all, the world contains a significant amount of good and evil for which either god could be held responsible. However, if belief in both gods is equally as reasonable, then religious believers are unjustified in favouring one hypothesis over the other. Therefore, in order to defend their faith, theists must respond to the evil-god challenge: the question of what justifies belief in good god over evil god.

Immortality and the Existence of God: Reformulating the Arguments of Plato, Anselm, and Gödel defends a modern version of Plato’s argument for the immortality of the soul. The self is essentially conscious and hence essentially living. It is therefore “deathless” and cannot receive death. But then, it also cannot become something else, nor can it be destroyed, since that would be receiving death also. So, the self or immortal, and immaterial. The book then considers materialist theories of the mind and rejects them. It formulates an argument from introspection which the author believes establishes substance dualism. The argument for immortality and the Ontological Argument for the existence of God are parallel in that attempt to establish the existence of necessary beings. Since immortality makes sense within a theistic context, the second half of the book defends a version of Gödel’s Ontological Argument for God’s existence, utilizing experience of the moral good and that mutual entailment of the attributes of God to argue that these attributes, including necessary existence, are logically coherent. In the final chapter, the author uses the central arguments in the book to support accounts of the afterlife from those who have had near-death experiences.

Does God exist? What are the various arguments that seek to prove the existence of God? Can atheists refute these arguments? The Existence of God: A Philosophical Introduction assesses classical and contemporary arguments concerning the existence of God: the ontological argument, introducing the nature of existence, possible worlds, parody objections, and the evolutionary origin of the concept of God the cosmological argument, discussing metaphysical paradoxes of infinity, scientific models of the universe, and philosophers’ discussions about ultimate reality and the meaning of life the design argument, addressing Aquinas’s Fifth Way, Darwin’s theory of evolution, the concept of irreducible complexity, and the current controversy over intelligent design and school education. Bringing the subject fully up to date, Yujin Nagasawa explains these arguments in relation to recent research in cognitive science, the mathematics of infinity, big bang cosmology, and debates about ethics and morality in light of contemporary political and social events. The book also includes fascinating insights into the passions, beliefs and struggles of the philosophers and scientists who have tackled the challenge of proving the existence of God, including Thomas Aquinas, and Kurt Gödel - who at the end of his career as a famous mathematician worked on a secret project to prove the existence of God. The Existence of God: A Philosophical Introduction is an ideal gateway to the philosophy of religion and an excellent starting point for anyone interested in arguments about the existence of God.
