“When we take the position that it is not only the programmer's responsibility to produce a correct program but also to demonstrate its correctness in a convincing manner, then the above remarks have a profound influence on the programmer's activity: the object he has to produce must be usefully structured.”

— Edsger W. Dijkstra

“For a number of years I have been familiar with the observation that the quality of programmers is a decreasing function of the density of go to statements in the programs they produce. More recently I discovered why the use of the go to statement has such disastrous effects, and I became convinced that the go to statement should be abolished from all "higher level" programming languages.”

Edsger W. Dijkstra (1930–2002) Dutch computer scientist

1960s

“We have come through a strange cycle in programming, starting with the creation of programming itself as a human activity. Executives with the tiniest smattering of knowledge assume that anyone can write a program, and only now are programmers beginning to win their battle for recognition as true professionals.”

Gerald M. Weinberg (1933–2018) American computer scientist

“To summarize: We have seen that computer programming is an art, because it applies accumulated knowledge to the world, because it requires skill and ingenuity, and especially because it produces objects of beauty. A programmer who subconsciously views himself as an artist will enjoy what he does and will do it better. Therefore we can be glad that people who lecture at computer conferences speak of the state of the Art.”

“Bad programmers worry about the code. Good programmers worry about data structures and their relationships.”

“The programmer, like the poet, works only slightly removed from pure thought-stuff. He builds his castles in the air, from air, creating by exertion of the imagination. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures….
Yet the program construct, unlike the poet's words, is real in the sense that it moves and works, producing visible outputs separate from the construct itself. [… ] The magic of myth and legend has come true in our time. One types the correct incantation on a keyboard, and a display screen comes to life, showing things that never were nor could be.”

“I like the observation that Forth is an amplifier: a good programmer can write a great program; a bad programmer a terrible one. I feel no need to cater to bad programmers.”

“Eichmann is 34 or 35 years old, a very active, adventurous man. He felt that this act against Jews was necessary and was fully convinced of its necessity and correctness, as I was.”

“It would be wrong to assume that one must stay with a research programme until it has exhausted all its heuristic power, that one must not introduce a rival programme before everybody agrees that the point of degeneration has probably been reached.”
