Is it possible to prove or disprove God’s existence? Arguments for the existence of God have taken many different forms over the centuries: the ontological, cosmological and teleological arguments; arguments which invoke miracles, religious experience and morality; and prudential arguments such as Pascal’s Wager. On the other hand are the arguments against theistic belief: the traditional problem of evil; the logical tensions between divine attributes such as omnipotence, omniscience and eternity; and arguments from the scale of the universe. In The Non-Existence of God, Nicholas Everitt reconsiders all of these arguments and examines the role that reason and knowledge play in the debate over God’s existence. He draws on recent scientific disputes over neo-Darwinism, the implication of big bang cosmology, and the temporal and spatial size of the universe; and discusses some of the most recent work on the subject, such as Plantinga’s anti-naturalism argument in favour of theism. Everitt’s controversial conclusion is that there is a sense in which God’s existence is disprovable, and that even in other senses a belief in God would be irrational.
