We begin by looking at some classic arguments for the existence of God. We then turn to the best-known argument against the existence of God - the problem of evil. Various classic attempts to show how observed evils can be squared with God's existence are examined, including theodicies and sceptical theism.
We then consider religious experience and the thought that some people might reasonably believe in God even without any supporting argument or evidence. Can some people 'just know' God exists? Does the fact that religious belief can be explained naturalistically - perhaps by the cognitive science of religion - effectively explain away religious belief? We investigate the extent to which disagreement between religious believers should lead us to be sceptical about religious belief. The supposed clash between science and religion, and the threat posed by science to religion, is investigated.
Finally we look at the Wittgensteinian suggestion that atheist critics of religious belief fail to understand what it is they are criticising, because they fail to understand how religious language is used.
