Experience shows that the success of a programming course critically depends on the choice of these examples.

During the process of stepwise refinement, a notation which is natural to the problem in hand should be used as long as possible.

Increasingly, people seem to misinterpret complexity as sophistication, which is baffling -- the incomprehensible should cause suspicion rather than admiration.

In the practical world of computing, it is rather uncommon that a program, once it performs correctly and satisfactorily, remains unchanged forever.

Software gets slower faster than hardware gets faster. (Or, sometimes known by] Grove [the head of Intel] giveth and Gates [the head of Microsoft] taketh away.)

A primary cause of complexity is that software vendors uncritically adopt almost any feature that users want.

I have never designed a language for its own sake.
