Program construction consists of a sequence of refinement steps.		101
But quality of work can be expected only through personal satisfaction, dedication and enjoyment. In our profession, precision and perfection are not a dispensible luxury, but a simple necessity.		102
In the practical world of computing, it is rather uncommon that a program, once it performs correctly and satisfactorily, remains unchanged forever.	Computers	103
My duty as a teacher is to train, educate future programmers.	Future, Teacher	104
Our ultimate goal is extensible programming (EP). By this, we mean the construction of hierarchies of modules, each module adding new functionality to the system.		105
Many people tend to look at programming styles and languages like religions: if you belong to one, you cannot belong to others. But this analogy is another fallacy.		106
A good designer must rely on experience, on precise, logic thinking; and on pedantic exactness. No magic will do.	Design	107
Experience shows that the success of a programming course critically depends on the choice of these examples.		108
I have never designed a language for its own sake.		109
Software development is technical activity conducted by human beings.		110
The possible solutions to a given problem emerge as the leaves of a tree, each node representing a point of deliberation and decision.		111
Clearly, programming courses should teach methods of design and construction, and the selected examples should be such that a gradual development can be nicely demonstrated.	Design	112
Indeed, the woes of Software Engineering are not due to lack of tools, or proper management, but largely due to lack of sufficient technical competence.		113
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.		114
But active programming consists of the design of new programs, rather than contemplation of old programs.	Design	115
It is evidently necessary to generate and test candidates for solutions in some systematic manner.		116
My being a teacher had a decisive influence on making language and systems as simple as possible so that in my teaching, I could concentrate on the essential issues of programming rather than on details of language and notation.	Teacher	117
Programming is usually taught by examples.		118
Usually its users discover sooner or later that their program does not deliver all the desired results, or worse, that the results requested were not the ones really needed.		119
Yet, I am convinced that there is a need for high quality software, and the time will come when it will be recognized that it is worth investing effort in its development and in using a careful, structured approach based on safe, structured languages.		120
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.		121
