Empiricist cut the branch on which they sit

Like the eighteenth-century Scottish philosopher David Hume, the modern language philosophers, intent on undermining theology, undermine themselves. Hume showed that the existence of God could not be proven if one begins with empirical evidence; in so doing he demonstrated that nothing at all could be proven with empirical evidence. God lives, despite the best efforts of Hume, and Christian theology remains, despite the best efforts of the language philosophers. The only things Hume and the language philosophers have refuted are themselves. - John Robbins, Forward to Clark's book Language and Theology, Pg. V or 5
