There is a quote from St. Augustine's City of God comparing governments to robberies. (HT Cafe Hayek) I'm not sure I'm in total agreement, and one may ask whether St. Augustine was just an early libertarian or is quoted out of a larger context. But the parallels drawn in the quote are intriguing. Of particular interest was his recounting of a meeting between Alexander the Great and a pirate who had been brought before him. If true, it would have been an interesting exchange.
Now I'm even more interested in reading Peter Leeson's The Invisible Hook. I just need to find the time to do so.
