Does God exist? What are the different arguments that seek to prove the existence of God? Are they valid arguments? The Existence of God: A Philosophical Introduction assesses classical and contemporary arguments concerning the existence of God, beginning with the classical arguments: the ontological argument, examining the arguments for and against it, introducing relevant topics as the nature of existence, modality, possible worlds and Gaunilo's parody objection. the cosmological argument, in light of metaphysical paradoxes of infinity, scientific models of the universe, and philosophers' discussions about the ultimate cause the teleological argument, discussing Aquinas's fifth way, the fine-tuning of the universe, the concept of irreducible complexity, and the current controversy over intelligent design. In a departure from standard introductions, Yujin Nagasawa then sets arguments about the existence of God in relation to recent research on miracles, neuroscience and the controversy over the possibility of a 'God spot' in the brain, and debates in ethics and morality in light of recent political and social events.He also brings to life some of the key personalities involved in debates about the existence of God, including Kurt Godel, who at the end of his career as a famous mathematician worked on an argument for the existence of God and George Lamaitre and Edwin Hubble and the 'big bang theory'. The Existence of God: A Philosophical Introduction is an ideal introduction to philosophy of religion and an excellent starting point for anyone interested in arguments about the existence of God.
