From Project Gutenberg, I bring you the English text of Sir Thomas More's most famous book, Utopia. Now you can read it for yourself. Thomas More was beheaded as a traitor when he refused to endorse the King of England's marriages. An inspiring movie was made about Sir Thomas, A Man For All Seasons (1966). I really recommend it; it is a very good movie. The enemy of Sir Thomas is a Mr. "Cromwell", played by the same actor who played Rumpole (of the Bailey). If you like Rumpole, you'll like the lawyerly arguing and legal suspense in A Man For All Seasons.
Utopia is presented for historical interest. It is the first major attempt to describe an ideal society since Plato wrote his Republic in the Greek language. Sir Thomas More, coming from a society that revered the Bible for more than a thousand years, described an ideal society which is much closer to God's standards than the one in Plato's republic. But as a Trinitarian Catholic, his ideal society has its flaws. It is, after all, not based on God's laws!
Back to Sir Thomas More, and the King Henry the VIII situation. If the King had advocated God's law instead of being a Christian, he would have married as many wives as he needed to produce an heir, without having to divorce and kill all his previous wives. Monogamy is deadly!
