The modern habit of saying "This is my opinion, but I may be wrong" is entirely irrational. If I say that it may be wrong, I say that is not my opinion. The modern habit of saying "Every man has a different philosophy; this is my philosophy and it suits me" ? the habit of saying this is mere weak-mindedness. A cosmic philosophy is not constructed to fit a man; a cosmic philosophy is constructed to fit a cosmos. A man can no more possess a private religion than he can possess a private sun and moon.
