Prof. Swinburne was Nolloth Professor of the Philosophy of the Christian Religion at the University of Oxford from 1985 until 2002, and is a Fellow of the British Academy. He has written some fourteen books on various philosophical and religious issues. His best known book, The Existence of God (2nd edition, 2004) claims that the traditional arguments of natural theology can be re-phrased as cumulative probabilistic arguments, which together make it significantly more probable than not that there is a God. He analyses arguments from the existence of laws of nature, those laws being such as to lead to the evolution of conscious human beings. Among the criteria for the probable truth of an explanation, he claims, is its simplicity. He discusses these criteria, among other places, in Epistemic Justification (2001).
