Who Was John Toland?

John Toland (30 November 1670 – 11 March 1722) was an Irish rationalist philosopher and freethinker, and occasional satirist, who wrote numerous books and pamphlets on political philosophy and philosophy of religion, which are early expressions of the philosophy of the Age of Enlightenment. Born in Ireland, he was educated at the universities of Glasgow, Edinburgh, Leiden and Oxford and was influenced by the philosophy of John Locke.

His first, and best known work, Christianity Not Mysterious (1696), opposed hierarchy in both church and state. In Ireland, copies were burned by the public hangman, and he was forced to flee the country never to return.
