“The reason I keep mentioning God is because I believe in God. A lot of people are surprised by that, what with it being 2014 and this being a technologically advanced secular culture. God is primarily regarded as the preserve of thick white people and angry brown people. Since Friedrich Nietzsche (deceased) declared, “God is dead,” we’ve been exploring the observation of British writer G. K. Chesterton, who said, “The death of God doesn’t mean man will believe in nothing but that he will believe in anything.” I’m a good example of that: at thirteen a believer in Lakeside, at eight a believer in biscuits, at seventeen a devoted wanker, at nineteen a fanatical drug user, before winding up in the monastery of celebrity.”

This quotation actually comes from page 211 of Émile Cammaerts' book The Laughing Prophet : The Seven Virtues and G. K. Chesterton (1937) in which he quotes Chesterton as having Father Brown say, in "The Oracle of the Dog" (1923): "It's the first effect of not believing in God that you lose your common sense." Cammaerts then interposes his own analysis between further quotes from Father Brown: "'It's drowning all your old rationalism and scepticism, it's coming in like a sea; and the name of it is superstition.' The first effect of not believing in God is to believe in anything: 'And a dog is an omen and a cat is a mystery.'" Note that the remark about believing in anything is outside the quotation marks — it is Cammaerts. The correct attribution was reportedly first traced by Pasquale Accardo. http://www.chesterton.org/ceases-to-worship/ It was also credited to Nigel Rees (as cited in First Things, 1997). http://books.google.com/books?id=NuQnAAAAYAAJ&q=%22The+first+effect+of+not+believing+in+God+is+to+believe+in+anything%22&dq=%22The+first+effect+of+not+believing+in+God+is+to+believe+in+anything%22&hl=en&ei=PSzcTvewIefx0gHqmrj0DQ&sa=X&oi=book_result&ct=result&resnum=2&ved=0CDUQ6AEwAQ

Context: Ladies and gentlemen, I came here to avoid as much as possible treading on your corns. I had intended to deal only with the basic issue of economics that dictates our lives from the cradle to the grave, regardless of our religion or moral beliefs. I see now that it was a mistake. If one enters a battle, he cannot be squeamish about a few corns. Here, then, are my answers: I do not believe in God, because I believe in man. Whatever his mistakes, man has for thousands of years past been working to undo the botched job your God has made.
As to killing rulers, it depends entirely on the position of the ruler. If it is the Russian Czar, I most certainly believe in dispatching him to where he belongs. If the ruler is as ineffectual as an American President, it is hardly worth the effort. There are, however, some potentates I would kill by any and all means at my disposal. They are Ignorance, Superstition, and Bigotry — the most sinister and tyrannical rulers on earth. As for the gentleman who asked if free love would not build more houses of prostitution, my answer is: They will all be empty if the men of the future look like him.
