The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise.

Progress is possible only if we train ourselves to think about programs without thinking of them as pieces of executable code.

The prisoner falls in love with his chains.

Are you quite sure that all those bells and whistles, all those wonderful facilities of your so called powerful programming languages, belong to the solution set rather than the problem set?

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.
