Enniscorthy Sweeny is introduced as a puzzling figure, often seen as a "spacious bungler" who always had "sufficient room" to work. He was a man both widely "known" and completely misunderstood. Despite many people feeling they grasped his essence without facts, thorough investigators found that the more they learned about him factually, the less they truly knew him.
About half the people in the world knew him spontaneously—they caught the essence of him without factual knowledge, understanding him in a way that did not rely on facts. Their knowledge consisted of a "woolly clutch of facts" that were not correct. Those who winnowed the facts properly found they knew him hardly at all. Paradoxically: the less they knew him, the more they liked him.
A popular idea exists that Sweeny has something "world-wrecking" about him, though there is nothing in the facts or pseudo-facts to support it. Was Enniscorthy Sweeny the man who left the iron door of hell open for world changing and ruination? Or was that door always open, and did he try to close it?
