As pessimism began to grow in the early twentieth century, Ehrenfels became increasingly concerned with reviving European culture (Valent 2016, § 9). According to Max Brod, Ehrenfels’ Cosmogony “was a document of this generation [the “Generation nevertheless” (Generation des Trotzdem)], which for the first time embodied a mood of impending doom, tough without vanishing into fear” (quoted from Frechette 2017, 325). It is also in this context that he developed his ideas for reforming sexual ethics.  In essence he advocated polygamy for the superior men, in order to increase the population of people with higher qualities. He was at the same time opposed to those who advocated racial purity and was instead all in favor of mixed races. He did not see Jews as a threat to the “Aryan race” and in fact acknowledged their great cultural achievements (PSIII, 262), although he did fear “the yellow peril” (see Ehrenfels 1908, Dickinson 2002). His proposal for a new sexual ethic in order to enhance the European stock was, however, not well received.  As the years went on, Ehrenfels himself lost enthusiasm for it, but was instead more concerned with developing a new religion. He did not think that Christianity, with its demands for faith where reason could no longer be effective, was viable. The new religion was to be built upon a thoroughly rational dualistic principle of cosmogony, which also to a large extent drew upon the concept of Gestalt qualities that he had developed early in his career. It should also be mentioned here that Ehrenfels found the same concept to be fruitful in the domain of mathematics.
