Vacationing in the Austrian Alps, Freud thanks Jung for defending his ideas at a conference in Amsterdam. Freud tells Jung that he is �better fitted for propaganda� because �all hearts open to you.� In replying to Freud�s letter, on September 11, 1907, Jung described his disgust at the speakers at the Amsterdam conference, most of whom he berated for �pouring unadulterated sewage� on Freud�s theories, filling Jung �up to the neck� with a �contempt bordering on nausea for the genus <em>Homo sapiens</em>.� Jung often expressed his unhappiness with what he considered Freud�s �timidness before the world,� his reluctance to defend �his case publicly.�
