Required reading - well worth the time - and quite entertaining. 
 Favorite quote: 
 "One of the strongest natural proofs of the folly of hereditary right in kings, is, that nature disapproves it, otherwise she would not so frequently turn it into ridicule by giving mankind an ass for a lion." 
 Another quote, which I find very applicable to current politics: 
 "Immediate necessity makes many things convenient, which if continued would grow into oppressions. Expedience and right are different things." 
 It's short, entertaining and very, very good. Read it. Borrow my copy.
