I have presented a preliminary over-view of several aspects of scientific theory construction and psycho-analysis. Some notions from science, in particular physics, have been considered. Paradigms are generally accepted achievements that for a time provide model problems and model solutions to a community of practitioners of a science. Without a theoretical framework normal scientific investigation cannot take place. However, this is a double-edged sword because the paradigm can be confining and thus bind down the research activities, as well.

A parallel was drawn between text-book science teaching and professionalization of a psycho-analytic institute. Both tend to be 'paradigm-bound' and novelty has little or no place in such an approach. I suggested that being 'paradigm-bound' is an explanation for at least a large number of contributions to our current psycho-analytic literature. Our professional commitments must not blind us to other possibilities.
