This is the habit of saying his philosophy does not matter, and this is done universally in the twentieth century. . . A man's opinion. Chesterton says that we can t get away from the fact that we have a general view of existence, whether we like it or not. It affects and involves everything we say or do, whether we like it or not. And our general view of things is based on our ultimate view of things.
Religion is never irrelevant.
This book is not an attack but a defense, a defense of the ancient truths that are under attack by modern heretics. Chesterton claims to have gained a deeper appreciation of the Christian Faith through the simple exercise of defending it. He says he never realized the great philosophic common sense of Christianity until the anti-Christian writers pointed it to him. Heresy, it turns out, is usually a distinct lack of common sense. A heresy is at best a half-truth, but usually even less than that.
