Sheer Poison? Wittgenstein's Philosophy of Religion

Anscombe once said to Anthony Kenny that "On the topic of religion, Wittgenstein is sheer poison". This paper offers an assessment of that view. I take it that Anscombe meant that Wittgenstein was a bad influence rather than that his views were necessarily false, although she seems to have been uncertain about what exactly his views were. In "Paganism, Superstition and Philosophy", she identifies five ideas that make up "a certain current in philosophy which has a strong historical connection with Wittgenstein". I identify some of the sources of these ideas, in Wittgenstein's writing and in work by some of his followers, and consider what Anscombe's objections to them might have been. I also look at whether we should think of these ideas as belonging either to Wittgenstein's philosophy of religion or to his personal beliefs. This will involve some consideration of how far we can, or should try to, separate the personal from the philosophical. So far as he held objectionable views about religion, I argue that these ought to be considered personal rather than philosophical.
