"During the process of stepwise refinement, a notation which is natural to the problem in hand should be used as long as possible."
"Clearly, programming courses should teach methods of design and construction, and the selected examples should be such that a gradual development can be nicely demonstrated."

Niklaus Emil Wirth was a Swiss computer scientist. He designed several programming languages, including Pascal, and pioneered several classic topics in software engineering. In 1984, he won the Turing Award, generally recognized as the highest distinction in computer science, "for developing a sequence of innovative computer languages".
"During the process of stepwise refinement, a notation which is natural to the problem in hand should be used as long as possible."
"Software gets slower faster than hardware gets faster."
"Whereas Europeans generally pronounce his name the right way (Nick-louse Veert), Americans invariably mangle it into Nickels Worth. This is to say that Europeans call him by name, but Americans call him by value."
"Reliable and transparent programs are usually not in the interest of the designer."
"In our profession, precision and perfection are not a dispensable luxury, but a simple necessity."
"In the practical world of computing, it is rather uncommon that a program, once it performs correctly and satisfactorily, remains unchanged forever."
"We have created a wealthy society with tens of millions of talented, resourceful individuals who play virtually no role whatsoever as citizens. Bringing these people in — with their networks of influence, their knowledge, and their resources — is the key to creating the capacity for shared intelligence that we need to solve our problems."
"As in respect of the first wonder we are all on the same level, how comes it that the philosophic mind should, in all ages, be the privilege of a few? The most obvious reason is this: The wonder takes place before the period of reflection, and (with the great mass of mankind) long before the individual is capable of directing his attention freely and consciously to the feeling, or even to its exciting causes. Surprise (the form and dress which the wonder of ignorance usually puts on) is worn away, if not precluded, by custom and familiarity."
"The dualistic philosophy reigned supreme in Europe, dominating the development of Western science. But with the advent of atomic physics, findings based on demonstrable experiment were seen to negate the dualistic theory, and the trend of thought since then has been back to the monistic conception of the ancient Taoists."
"Under the rule of a repressive whole, liberty can be made into a powerful instrument of domination. The range of choice open to the individual is not the decisive factor in determining the degree of human freedom, but what can be chosen and what is chosen by the individual."
"All economic activity is carried out through time. Every individual economic process occupies a certain time, and all linkages between economic processes necessarily involve longer or shorter periods of time."
"I believe that the main lesson which our generation has learnt is that we must find a new limit for the activities of government, a limit which leaves ample scope for sensible experimentation but which secures the freedom of the individual as the mainspring of all social and political activity. The whole purpose of these lectures has been to suggest that we can find such a limit if we are willing to revive and develop the ancient ideal of the Rule of Law."
