It is on this ideological sticking point, rather than the myth of Progress (1) in its Victorian formulation, that one might profitably interrogate the contemporary Oxford School, especially in light of Ruse's soft spot for taking post-Hamilton English adaptationists as the very models of modern professionalism.
