A philosopher ended his own book by telling you to throw it away

Ludwig Wittgenstein's Tractatus Logico-Philosophicus builds an entire theory of language and logic, then closes by comparing its own propositions to a ladder: useful for climbing, but nonsense once you've used it to see the world clearly. He instructs the reader to discard the ladder after climbing it.
