G. K. Chesterton, a celebrated writer of fiction, was also a renowned author of essays and a fierce polemicist who left, after his death, in 1936, the Autobiography we present today. Beyond tracing the lifeblood of his memory, Chesterton opens a window on the world that occupied him as a journalist and leaflet writer-that is how he wanted to be remembered-and with whom he rarely maintained a peaceful coexistence. Chesterton is the visceral, controversial, and passionate man who did not hesitate to proclaim his claim to a corrupt political system and propaganda morality against the background of the Boer War (the British incursion into South Africa, which was so popular among the English society) and the First World War. His conversion to Catholicism ended up placing him in the role of an eccentric and contentious character. Today, by his extraordinary intellectual acuteness and his brilliant ability to use the paradox as a weapon of argument, Chesterton remains the stimulating thinker who succeeded in keeping thousands of readers in suspense.
