Gilbert Keith Chesterton (29 May 1874 – 14 June 1936) was one of the most influential English writers of the 20-th century. His prolific and diverse output included journalism, philosophy, poetry, biography, Christian apologetics, fantasy and detective fiction. Chesterton has been called the "prince of paradox." Time magazine, in a review of a biography of Chesterton, observed of his writing style: "Whenever possible Chesterton made his points with popular sayings, proverbs, allegories—first carefully turning them inside out." For example, Chesterton wrote the following: Thieves respect property. They merely wish the property to become their property that they may more perfectly respect it. Chesterton is well known for his reasoned apologetics and even those who disagree with him have recognized the universal appeal of such works as Orthodoxy and The Everlasting Man. Chesterton, as political thinker, cast aspersions on both Liberalism and Conservatism, saying: The whole modern world has divided itself into Conservatives and Progressives. The business of Progressives is to go on making mistakes. The business of the Conservatives is to prevent the mistakes from being corrected. Chesterton routinely referred to himself as an "orthodox" Christian, and came to identify such a position with Catholicism more and more, eventually converting to Roman Catholicism. George Bernard Shaw, Chesterton's "friendly enemy" according to Time, said of him, "He was a man of colossal genius".
