The initial motive for developing APL was to provide a tool for writing and teaching. Although APL has been exploited mostly in commercial programming, I continue to believe that its most important use remains to be exploited: as a simple, precise, executable notation for the teaching of a wide range of subjects.

Although mathematical notation undoubtedly possesses parsing rules, they are rather loose, sometimes contradictory, and seldom clearly stated. [...] The proliferation of programming languages shows no more uniformity than mathematics. Nevertheless, programming languages do bring a different perspective. [...] Because of their application to a broad range of topics, their strict grammar, and their strict interpretation, programming languages can provide new insights into mathematical notation.

"The basic teaching of Buddhism is the teaching of transiency or change. That everything changes is the basic truth for each existence. No one can deny this truth and all teaching of Buddhism is condensed within it. This is the teaching for all of us. Wherever we go this teaching is true. This teaching is also understood as the teaching of selflessness. Because each existence is in constant change, there is no abiding self.
Shunryu Suzuki
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.
Kenneth E. Iverson
The utility of a language as a tool of thought increases with the range of topics it can treat, but decreases with the amount of vocabulary and the complexity of grammatical rules which the user must keep in mind. Economy of notation is therefore important.
Kenneth E. Iverson
I shall not have it judged by any man, not even by any angel. For since I am certain of it, I shall be your judge and even the angels’ judge through this teaching (as St. Paul says [1 Cor. 6:3]) so that whoever does not accept my teaching may not be saved - for it is God’s teaching and not mine.
