Hanlon's Razor
Origin
Appeared in 1980 in "Murphy's Law Book Two" (ed. Arthur Bloch) — submitted anonymously by Robert J. Hanlon of Pennsylvania. The spirit is older: Goethe's 1774 "Sorrows of Young Werther", Heinlein's 1955 "Logic of Empire". Hanlon compressed the intuition into one sentence.
Meaning
A coworker doesn't reply, a friend doesn't call, a politician makes a strange decision — we instinctively assume malice. But statistically, most actions stem from forgetfulness, busyness, or ignorance. Assuming malice damages relationships and wears down the heart. Hanlon proposes a kinder first hypothesis.
Lesson — Meeting Eastern Classics
Analects 1.16: "Do not worry that others do not know you; worry that you do not know others." Confucius taught Hanlon 2,500 years earlier. The one who assumes ignorance ends up knowing better.
"愚" combines monkey (禺) with heart (心) — originally the impulsive mind of a monkey, foolishness. Hanlon asks us to place 愚 as the first explanation — it is both kinder and more accurate.
