The Nietzsche scholar Walter Kaufmann told a story of how, in 1952, just two years after publishing his ground-breaking book, Nietzsche: Philosopher, Psychologist, Antichrist, he visited the Cambridge philosopher CD Broad at Trinity College. During their conversation, Broad mentioned someone by the name of Salter. Was that, Kaufmann asked, the Salter who had written a book on Nietzsche? “Dear no,” Broad replied, “he did not deal with crackpot subjects like that; he wrote about psychical research.”
In the years immediately before, during and just after the Second World War, Nietzsche’s reputation in the English-speaking world was at its lowest, largely owing to the fact that his work had been, with the support of his virulently anti-Semitic sister Elisabeth, appropriated by the Nazis. In their hands, Nietzsche’s notion of the Übermensch (I prefer to use the original German than any of the published translations; “superman” sounds silly, and “beyond-man” and “overman” do not sound like natural English) became associated with notions of Aryan racial superiority, while his idea of the “will to power” was used to justify militarism and authoritarianism.
