Lisp - A thinking man's language

SQL, Lisp, and Haskell are the only programming languages that I've seen where one spends more time thinking than typing.

Java was, as Gosling says in the first Java white paper, designed for average programmers. It's a perfectly legitimate goal to design a language for average programmers. (Or for that matter for small children, like Logo.) But it is also a legitimate, and very different, goal to design a language for good programmers.
