The philosophical concept of (scientific) structuralism is related to that of epistemic structural realism (ESR).[3] ESR, a position originally and independently held by Henri Poincaré (1902),[8][9] Bertrand Russell (1927),[10] and Rudolf Carnap (1928),[11] was resurrected by John Worrall (1989), who proposes that there is retention of structure across theory change.
