30 Philosophers, Chapter 23: Roger Williams and Liberalism. 

Williams became a man 400 years ahead of his time by examining what his age took for granted.

Roger Williams was born in England around 1602, in Smithfield, situated at the heart of London. Williams officially founded Providence Plantations in 1636 with an informal agreement with the local Native American leaders. It became the fifth American colony and the second in the New England region. In 1644, he published a series of pamphlets, the more contentious ones anonymously, leading up to penning what would become his magnum opus: “The Bloudy Tenent of Persecution,” or “Bloody Tenet.” More than a historical or religious treatise, the Bloody Tenet is a seminal work. It launched a full-throttle assault on the prevailing norms of religious and political intolerance that plagued both Old and New England. Williams passionately argued for the separation of church and state.
