History of purity

Gadamer says, “One day someone should write the history of ‘purity.’” He cites one H. Sedlmayr, who “refers to Calvinistic purism and the deism of the Enlightenment.” Kant would play a key role: He “linked himself directly with the classical Pythagorean and Platonic doctrine of purity.” Gadamer wonders whether “Platonism is the common root of all modern ‘purism.’”
