• We often treat children as if they're not very competent to do anything on their own. So we make them stop learning in a natural way - by exploring. Logo [the computer programming language ] allows them to find their way around the computer, as they would find their way around the house, uncontaminated by the bureaucracies of schools.

• It's kind of pathetic actually that we are all sitting here talking about Forth. It is not the wave of the future. It's never been the wave of the future. It's not within our power to make it the wave of the future.

• The most powerful programming language is Lisp. If you don't know Lisp (or its variant, Scheme), you don't appreciate what a powerful language is. Once you learn Lisp you will see what is missing in most other languages.

• What I was proud of was that I used very few parts to build a computer that could actually speak words on a screen and type words on a keyboard and run a programming language that could play games. And I did all this myself.

• My impression was and is that many programming languages and tools represent solutions looking for problems, and I was determined that my work should not fall into that category. Thus, I follow the literature on programming languages and the debates about programming languages primarily looking for ideas for solutions to problems my colleagues and I have encountered in real applications. Other programming languages constitute a mountain of ideas and inspiration-but it has to be mined carefully to avoid featurism and inconsistencies.

• Overemphasis of efficiency leads to an unfortunate circularity in design: for reasons of efficiency early programming languages reflected the characteristics of the early computers, and each generation of computers reflects the needs of the programming languages of the preceding generation.

• The properties of executability and universality associated with programming languages can be combined, in a single language, with the well-known properties of mathematical notation which make it such an effective tool of thought.

• With the computer and programming languages, mathematics has newly-acquired tools, and its notation should be reviewed in the light of them. The computer may, in effect, be used as a patient, precise, and knowledgeable "native speaker" of mathematical notation.
