Gilbert Keith Chesterton (1874-1936) was an influential English writer of the early 20th 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. " He wrote in an off-hand, whimsical prose studded with startling formulations. He is one of the few Christian thinkers who are equally admired and quoted by both liberal and conservative Christians, and indeed by many non-Christians.
