A language that doesn't affect the way you think about programming is not worth knowing.

When someone says, "I want a programming language in which I need only say what I want done," give him a lollipop.

Every program has (at least) two purposes: the one for which it was written and another for which it wasn't.

Every reader should ask himself periodically “Toward what end, toward what end?”—but do not ask it too often lest you pass up the fun of programming for the constipation of bittersweet philosophy.

There is no such thing as a free variable.

If your computer speaks English, it was probably made in Japan.

A year spent in artificial intelligence is enough to make one believe in God.
