John Toland (30 November 167011 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, was Christianity Not Mysterious (1696). Biography Very little is known of Toland's early life. He was born in Ardagh on the Inishowen Peninsula, a predominantly Catholic and Irish-speaking region in northwestern Ireland. His parents are unknown. He would later write that he had been baptised Janus Junius, a play on his name that recalled both the Roman two-faced god Janus and Junius Brutus, reputed founder of the Roman Republic. According to his biographer Pierre des Maizeaux, he adopted the name John as a schoolboy with the encouragement of his school teacher. Having formally converted from Catholicism to Protestantism at the age of 16, Toland got a scholarship to study theology at the University of Glasgow.

The Leiden scholarship had been provided by wealthy English Dissenters, who hoped Toland would go on to become a minister for Dissenters. In Toland's first book Christianity not Mysterious (1696), begun at Oxford, he argued that the divine revelation of the Bible contains no true mysteries; rather, all the dogmas of the faith can be understood and demonstrated by properly trained reason from natural principles. His argument immediately attracted several rebuttals, and he was prosecuted by a grand jury in London. As he was a subject of the Kingdom of Ireland, members of the Parliament of Ireland proposed that he should be burnt at the stake, and in his absence three copies of the book were burnt by the public hangman in Dublin as the content was contrary to the core doctrines of the Church of Ireland. Toland bitterly compared the Protestant legislators to "Popish Inquisitors who performed that Execution on the Book, when they could not seize the Author, whom
