On methodological taboos
“To proceed beyond the limitations of a given level of knowledge, the researcher, as a rule, has to break down methodological taboos which condemn as “unscientific” or “illogical” the very methods or concepts which later on prove to be basic for the next major progress.”
Kurt Lewin (1949) cited in Argyris et al. (1985) Action Science: Concepts, Methods, and Skills for Research and Intervention
