That ¡°Damnably Obscure Proposition¡±
Anscombe¡¯s Last Words on C. S. Lewis
According to C. S. Lewis, Naturalism is beset by a ¡°cardinal difficulty.¡± It can be known to be true only by way of valid reasoning¡ªsomething precluded by Naturalism itself. The Naturalist¡¯s belief in Naturalism hasn¡¯t been caused by a rational argument; it has resulted instead from irrational causes. In the face of Elizabeth Anscombe¡¯s powerful and searching criticisms, Lewis significantly revised his argument against Naturalism for the 1960 edition of his book Miracles. Anscombe¡¯s last words on Lewis¡¯ argument were delivered at a meeting of the Oxford C. S. Lewis Society, November 12, 1985. The rewritten argument, she contends, is ¡°genuinely problematic.¡± First, it fails to answer a question Lewis says it must: what is the connection between the logical grounds of a belief and its actual occurrence? Secondly, it invokes the ¡°damnably obscure proposition ¡®knowledge determined only by the truth it knows¡¯¡±¡ªa proposition ¡°obviously crucial¡± to Lewis¡¯ case, but which he sadly ¡°doesn¡¯t explore.¡± I argue that Anscombe last words here are mistaken on both counts.
