To err is human

You learn from your mistakes, but there are too many mistakes to make them all yourself. That's why we publish. We share our knowledge with others, so that they don't have to repeat the same mistake.
-- Niels Ferguson, "Censorship in action: why I don't publish my HDCP results," The Risks Digest, Volume 21: Issue 61

Something out of nothing

Write a paper promising salvation, make it a "structured" something or a "virtual" something, or "abstract", "distributed" or "higher-order" or "applicative" and you can almost be certain of having started a new cult.
-- E.W. Dijkstra, "EWD 709: My hopes of computing science," April 1979.
