Educational technique needs a philosophy, which is a matter of faith rather than of science.

Hans Freudenthal
The case of methodology is analogous though less clear. Nobody would object to the subject of methodology being science, or some pseudo science. On closer inspection, however, this agreement is no more than a verbal coincidence. It rests on what is meant by science, as reported as a subject of methodology. In fact the subject methodologists call science is more often than not different from what scientists call science. Methodologists are inclined to consider a science as a linguistic system whereas the scientist would only admit that his science has a language, not that it is a language.

Hans Freudenthal
Science should be distiguished from technique and its scientific instrumentation, technology. Science is practised by scientists, and techniques by 'engineers' — a term that in our terminology includes physicians, lawyers, and teachers. If for the scientist knowledge and cognition are primary, it is action and construction that characterises the work of the engineer, though in fact his activity may be based on science. In history, technique often preceded science.

Hans Freudenthal
No scientist is as model minded as is the statistician; in no other branch of science is the word model as often and consciously used as in statistics.
