"My propositions serve as elucidations in the following way:
anyone who understands them eventually recognizes them as
nonsensical, when he has used them -- as steps -- to climb
up beyond them. (He must, so to speak, throw away the ladder
after he has climbed up it.)" -- Ludwig Wittgenstein, Tractatus
The first time I met Wittgenstein, I was
late. "The traffic was murder," I explained.
He spent the next forty-five minutes
analyzing this sentence. Then he was silent.
