Thinking further, what does the paradigm shift from, and what does it shift to?
Why is this paradigm shift necessary, which may be the same as why it matters? To us? To our colleagues? To our children? To our communities? To our society?
For interest, I share the following and am guessing that we are mainly talking about paradigm in the sociological sense, although I am also guessing that we have a tendency to look backwards to exemplary past achievements rather than forwards to achievements that are yet to accomplished?
Kuhn, T. S. (1996). The structure of scientific revolutions. 3rd edition. Chicago: University of Chicago Press.
On the one hand, [paradigm] stands for the entire constellation of beliefs, values, techniques, and so on shared by the members of a given community [sociological]. On the other, it denotes a sort of element in that constellation, the concrete puzzle-solutions which, employed as models or examples, can replace explicit rules as a basis for the solution of the remaining problems of normal science [exemplary past achievements].
