The excerpt is only 9 pages long, large-type, but it effectively expresses the basis of liberty and of the Anarcho-Capitalist position. The first 8 paragraphs are filled with 19th century talk of God and creation and the created nature of man, but his more concrete observations made in and after these paragraphs can be confirmed and defended by atheists, too.
