Chestertonian Realism as the Cure for Modern Insanity

Chesterton tells us that modern man suffers from insanity, and he is correct; but Chesterton was writing to men of Modernity who were just becoming Modernists. In our day, we would be so lucky to be around mad modern men. How much easier it would be to discuss philosophy and religion with a maniac; this would be quite the luxury. However, we are now in post-Modernity, where Modernism is passé.
