His second preoccupation was literary criticism. Chesterton's third major concern was theology and religious argument. He was converted from Anglicanism to Roman Catholicism in 1922. When it was not uproariously comic, his verse was frankly partisan and didactic. His essays developed his shrewd, paradoxical irreverence to its ultimate point of real seriousness.
Many readers value Chesterton's fiction most highly.
Chesterton's friendships were with men as diverse as H.G. Wells, Shaw, Belloc, and Max Beerbohm. His Autobiography was published in 1936.
