In this paper I wish to discuss some relationships between philosophy and science, or rather, between the philosophy of science and the natural sciences, as well as the role of research programmes in these relationships. My interest in the topic rises out of the problems involved in teaching philosophy, and especially epistemology, to science, engineering and technology students. My “field experience” in the last five years has led me to the conclusion that the purpose is better served through a programme (...) of courses of different levels carried out by the joined forces and complementary efforts of philosophers and scientists. However, I do not intend to discuss either this conclusion or my own teaching experiences concerning a particular educational system at a particular period — in fact, one of reformation. If I mention this, it is in order to draw attention to two implicit distinctions, made by teachers and students, philosophers and scientists, but not always in the same manner, which may become the source of dispute when one attempts to make them explicit. The two distinctions are (a) the one between philosophy (of science) and (the natural) science(s), and (b) the one between the view of science presented in the philosophy of science and the view of science created by the scientists and science teachers.
