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.

The truth is that there are no things for which men will make such herculean efforts as the things of which they know they are unworthy.

Even the moon is only poetical because there is a man in the moon.
