Program construction consists of a sequence of refinement steps.

Good engineering is characterized by gradual, stepwise refinement of products that yields increased performance under given constraints and with given resources.

But active programming consists of the design of new programs, rather than contemplation of old programs.

Nevertheless, I consider OOP as an aspect of programming in the large; that is, as an aspect that logically follows programming in the small and requires sound knowledge of procedural programming.

During the process of stepwise refinement, a notation which is natural to the problem in hand should be used as long as possible.

Programs should be written and polished until they acquire publication quality.

The idea that one might derive satisfaction from his or her successful work, because that work is ingenious, beautiful, or just pleasing, has become ridiculed.
