Heretics is a collection of 20 essays and articles by G. K. Chesterton, in which he appraises prominent figures of his time in the worlds of literature and the arts. He scrutinises the work of luminaries such as George Bernard Shaw, Rudyard Kipling, and H. G. Wells with insight and wit, criticizing those who hold incomplete and flawed views of "life, the universe, and everything". His observations on Omar Khayyam and Kipling are laugh-out-loud funny, for example when he questions what, exactly, it is that Kipling has always tried to say?
