E. M. Forster wrote this at the height of Nazi Aryan race theory:

“Whether there ever was such an entity as a ‘pure race’ is debateable, but there certainly is not one in Europe today – the internationalism of the Roman Empire and of the Middle Ages have seen to that. Consequently there never can be a pure race in the future. Europe is mongrel for ever, and so is America”:
