“Simplicity is a great virtue but it requires hard work to achieve it and education to appreciate it. And to make matters worse: complexity sells better.”

— E. W. Dijkstra (1984) On the nature of Computing Science (EWD896).


“Testing shows the presence, not the absence of bugs.”

— E. W. Dijkstra, J.N. Buxton and B. Randell, eds, Software Engineering Techniques, April 1970, p. 16.


“If you want more effective programmers, you will discover that they should not waste their time debugging.  They should not introduce the bugs to start with.”

E. W. Dijkstra, 1972 Turing Award Lecture
