This chapter looks at Kuhn’s (subsequently notorious) concept of the paradigm. Kuhn rejected the received view that the locus of scientific activity was theories that consisted of sets of propositions; rather, science was embodied in what Kuhn called paradigms. The chapter takes liberty of starting with Kuhn’s ‘final’ formulation of paradigm, which bifurcates into the concepts of ‘exemplars’ and the ‘disciplinary matrix’ respectively; we also examine the interrelations between these two elements. The chapter concludes by examination one of the key motivations for introducing the concept: the rejection of the idea that science is (or was) practised by following rules. Kuhn’s argument was that science was essentially embodied by its practice, but by adhering to methodological precepts (though such precepts could be formulated post-hoc as falling out of practice).
