Why has elegance found so little following? That is the reality of it. Elegance has the disadvantage, if that's what it is, that hard work is needed to achieve it and a good education to appreciate it.

I mentioned the non-competitive spirit explicitly, because these days, excellence is a fashionable concept. But excellence is a competitive notion, and that is not what we are heading for: we are heading for perfection.

Simplicity is prerequisite for reliability.

About the use of language: it is impossible to sharpen a pencil with a blunt axe. It is equally vain to try to do it with ten blunt axes instead.

The ability of discerning high quality unavoidably implies the ability of identifying shortcomings.

The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.

Program testing can be used to show the presence of bugs, but never to show their absence!

The lurking suspicion that something could be simplified is the world's richest source of rewarding challenges.

Elegance is not a dispensable luxury but a factor that decides between success and failure.

There should be no such thing as boring mathematics.

Mathematicians are like managers - they want improvement without change.

Programming is one of the most difficult branches of applied mathematics; the poorer mathematicians had better remain pure mathematicians.

Don't compete with me: firstly, I have more experience, and secondly, I have chosen the weapons.

Teaching to unsuspecting youngsters the effective use of formal methods is one of the joys of life because it is so extremely rewarding.

Why has elegance found so little following? That is the reality of it. Elegance has the disadvantage, if that's what it is, that hard work is needed to achieve it and a good education to appreciate it.

Computer science is no more about computers than astronomy is about telescopes.

Perfecting oneself is as much unlearning as it is learning.

The students that, like the wild animal being prepared for its tricks in the circus called "life", expects only training as sketched above, will be severely disappointed: by his standards he will learn next to nothing.

If 10 years from now, when you are doing something quick and dirty, you suddenly visualize that I am looking over your shoulders and say to yourself: 'Dijkstra would not have liked this', well that would be enough immortality for me.

The traditional mathematician recognizes and appreciates mathematical elegance when he sees it. I propose to go one step further, and to consider elegance an essential ingredient of mathematics: if it is clumsy, it is not mathematics.

APL is a mistake, carried through to perfection. It is the language of the future for the programming techniques of the past: it creates a new generation of coding bums.

The use of COBOL cripples the mind; its teaching should, therefore, be regarded as a criminal offense.

Object-oriented programming is an exceptionally bad idea which could only have originated in California.

Aim for brevity while avoiding jargon.

It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration.

The competent programmer is fully aware of the limited size of his own skull. He therefore approaches his task with full humility, and avoids clever tricks like the plague.

Many mathematicians derive part of their self-esteem by feeling themselves the proud heirs of a long tradition of rational thinking; I am afraid they idealize their cultural ancestors.

The students that, like the wild animal being prepared for its tricks in the circus called 'life', expects only training as sketched above, will be severely disappointed: by his standards he will learn next to nothing.

Mathematicians are like managers they want improvement without change.

If debugging is the process of removing software bugs, then programming must be the process of putting them in.

If we wish to count lines of code, we should not regard them as lines produced but as lines spent.

Education is the cornerstone of our communities and our country.

Democracy cannot succeed unless those who express their choice are prepared to choose wisely. The real safeguard of democracy, therefore, is education.

I feel that education needs an overhaul - courses are obsolete and grades are on the way out.

Education is a private matter between the person and the world of knowledge and experience, and has little to do with school or college.

Only time, education and plenty of good schooling will make anti-segregation work.

The education of my brother and myself was of paramount importance to my parents, and in addition to their strong encouragement, they were prepared to make any sacrifice to further our intellectual development.

We have a responsibility to ensure that every individual has the opportunity to receive a high-quality education, from prekindergarten to elementary and secondary, to special education, to technical and higher education and beyond.

Yesterday in this country we had people die of hunger and malnutrition. In some parts of this country, the infant mortality rate rivals that of sub-Saharan Africa. We have a public education system that ranks below that of almost any other Western nation.

The test and the use of man's education is that he finds pleasure in the exercise of his mind.

We spend more than a million dollars a year on our colleges and university, and it is money well spent; but we must have education that fits not the few but the many for the business of life.

Every single major push in education has made it worse and right now it's really bad because everything we've done is de-humanizing education. It's destroying the possibility of the teacher and the student having a warm, friendly, intellectual relationship.

It is only the ignorant who despise education.

The benefits of education and of useful knowledge, generally diffused through a community, are essential to the preservation of a free government.

When the students are occupied, they're not juvenile delinquents. I believe that education is a capital investment.

Don't give up on the child. Give the child an education. Give them daily love.

Education is our greatest opportunity to give an irrevocable gift to the next generation.

If you stop and think about our history, one of the reasons we had an American century and there is an American dream was because at key points in our history we made very bold decisions about making sure that there was very broad, universal access to quality education.

And I also thought that Richard Nixon was the greatest political education we have ever had, but it looks like we need to relearn them again.
