Though this paper is mostly about a sense of “profession” common in much of the West, it explains how the term might apply in any country (especially how the profession of engineering differs from the function, discipline, and occupation of engineering). To do that, I have to explain the connection between “profession” (in my preferred sense) and another hard-to-translate term, “code of ethics” (in the sense it has in the expression “code of engineering ethics”). To understand engineering (or any other (...) occupation) as a profession is to adopt a certain conception of it, one neither old nor (yet) universal. With that conception in hand, it should be possible for social science to answer the question posed in the title. (shrink)
