We shall do a much better programming job, provided that we approach the task with a full appreciation of its tremendous difficulty, provided that we stick to modest and elegant programming languages, provided that we respect the intrinsic limitations of the human mind and approach the task as Very Humble Programmers.

It is a mistake to think that programmers wares are programs. Programmers have to produce trustworthy solutions and present it in the form of cogent arguments. Programs source code is just the accompanying material to which these arguments are to be applied to.

In the good old days physicists repeated each other's experiments, just to be sure. Today they stick to FORTRAN, so that they can share each other's programs, bugs included.

Beauty is our business.

Computer science has as much to do with computers as astronomy has to do with telescopes.

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

If there is one 'scientific' discovery I am proud of, it is the discovery of the habit of writing without publication in mind.
