 A variety of arguments have been developed that God is necessary to explain human awareness of moral truth (or moral knowledge, if one believes that this moral awareness amounts to knowledge). Richard Swinburne (2004, 218), for example, argues that there is no “great probability that moral awareness will occur in a Godless universe.” On Swinburne’s view, moral truths are either necessary truths or contingent truths that are grounded in necessary truths. For example, it is obviously contingent that “It is wrong to drop an atomic bomb on Hiroshima,” since it is contingent that there exists a city such as Hiroshima. But one might hold that this proposition is true (assuming it is) because of some other truth such as “It is wrong intentionally to kill innocent humans” which does hold universally and is necessarily true. Swinburne does not think that an argument to God’s existence from moral facts as such is powerful, increasing the likelihood of theism only a little. However, the fact that we humans are aware of moral facts is itself surprising and calls for an explanation.
