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#xE2;#xAC;" discussions about ultimate reality and the meaning of life. The design argument, addressing Aquinas#xE2;#xAC;"s Fifth Way, Darwin#xE2;#xAC;"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 G#xC3;#xB6;del - 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 Introductionis an ideal gateway to the philosophy of religion and an excellent starting point for anyone interested in arguments about the existence of God.
