My favorite chapter was titled, "The 'Torah' of Liberalism," the idea being that many Jewish people who lost their faith replaced it with faith in Das Kapital. I would include in the official canon of liberalism all of the works of Charles Darwin. It was Darwin who said higher forms of life evolved from lower forms of life and that humans were higher than animals for scientific reasons, not because humans have souls. Having read From Darwin to Hitler: Evolutionary Ethics, Eugenics, and Racism in Germany and Liberal Fascism: The Secret History of the American Left, From Mussolini to the Politics of Meaning, I think Darwinism is responsible for the colonial genocide in South-West Africa in the beginning of the 20th century, the Tuskegee syphilis experiment, World War I, racist immigration laws, World War II, the Holocaust, and the genocide in Russia, China, and Cambodia. Darwin undermined faith in God more than Marx. The reason I believe our freedom is before God is that I know humans have souls and I know something about our salvation history.
One criticism I have is that Podhorezt calls Nazis right-wingers instead of left-wingers. In this he is following Jacob Katz (From Prejudice to Destruction: Anti-Semitism, 1700-1933) who traced Nazism back to modern anti-semitism, which started in Germany in the early 1870s. This movement was certainly right-wing because it was trying to undo the emancipation of Jewish people. But Hitler was also a Darwinist and a socialist.
