My being a teacher had a decisive influence on making language and systems as simple as possible so that in my teaching, I could concentrate on the essential issues of programming rather than on details of language and notation.

My duty as a teacher is to train, educate future programmers.

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

I am convinced that there is a need for high quality software, and the time will come when it will be recognized that it is worth investing effort in its development and in using a careful, structured approach based on safe, structured languages.

Good engineering is characterized by gradual, stepwise refinement of products that yields increased performance under given constraints and with given resources.

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