Avicenna believes that God must be understood in the first place as the Necessary Existent (wâǧib al-wuǧûd). In his various works, he provides different versions of an ingenious argument for the existence of the Necessary Existent—the so-called Proof of the Sincere (burhân al-ṣiddîqîn)—and argues that all the properties that are usually attributed to God can be extracted merely from God's having necessary existence. Considering the centrality of tawḥîd to Islam, the first thing Avicenna tries to extract from God's necessary existence is God's oneness. The aim of the present Element is to provide a detailed discussion of Avicenna's arguments for the existence and unity of God. Through this project, the author hopes to clarify how, for Avicenna, the Islamic concept of monotheism is intertwined with the concept of essential existence.

Necessary Existence breaks ground on one of the deepest questions anyone ever asks: why is there anything? The classic answer is in terms of a necessary foundation. Yet, why think that is the correct answer? Pruss and Rasmussen present an original defense of the hypothesis that there is a concrete necessary being capable of providing a foundation for the existence of things. They offer six main arguments, divided into six chapters. The first argument is an up-to-date presentation and assessment of a traditional causal-based argument from contingency. The next five arguments are new "possibility-based" arguments that make use of twentieth-century advances in modal logic. The arguments present possible pathways to an intriguing and far-reaching conclusion. The final chapter answers the most challenging objections to the existence of necessary things.

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.

In many places and times, and for many people, God's existence has been rather less than a clear fact. According to the hiddenness argument, this is actually a reason to suppose that it is not a fact at all. The hiddenness argument is a new argument for atheism that has come to prominence in philosophy over the past two decades. J. L. Schellenberg first developed the argument in 1993, and this book offers a short and vigorous statement of its central claims and ideas. Logically sharp but so clear that anyone can understand, the book addresses little-discussed issues such as why it took so long for hiddenness reasoning to emerge in philosophy, and how the hiddenness problem is distinct from the problem of evil. It concludes with the fascinating thought that retiring the last of the personal gods might leave us nearer the beginning of religion than the end. Though an atheist, Schellenberg writes sensitively and with a nuanced insider's grasp of the religious life. Pertinent aspects of his experience as a believer and as a nonbeliever, and of his own engagement with hiddenness issues, are included. Set in this personal context, and against an authoritative background on relevant logical, conceptual, and historical matters, The Hiddenness Argument's careful but provocative reasoning makes crystal clear just what this new argument is and why it matters.

Philosophy of Religion provides an account of the central issues and viewpoints in the philosophy of religion but also shows how such issues can be rationally assessed and in what ways competing views can be rationally assessed. It includes major philosophical figures in religious traditions as well as discussions by important contemporary philosophers. Keith Yandell deals lucidly and constructively with representative views from Judaism, Christianity, Islam, Hinduism, Buddhism, and Jainism. This book will appeal to students of both philosophy and religion as well as to the general reader interested in the subject. Unique features of Philosophy of Religion: * key reading and new reading in the subject area * questions at the ends of chapters * a glossary of philosophical terms * annotated further reading

The main question of this Element is how the existence, supremacy, and uniqueness of an almighty and immaterial God bear on our own nature. It aims to uncover lessons about what we are by thinking about what God might be. A dominant theme is that Abrahamic monotheism is a surprisingly hospitable framework within which to defend and develop the view that we are wholly material beings. But the resulting materialism cannot be of any standard variety. It demands revisions and twists on the usual views. We can indeed learn about ourselves by learning about God. One thing we learn is that, though we are indeed wholly material beings, we're not nearly as ordinary as we might seem.
