Hitler’s belief in racial hierarchy was supported by many scientists of the day, both in Germany and abroad. This must make us cautious when people suggest that we can replace religion with science and expect a better world to emerge. Science is not designed to give us morals. It can help us build chemical weapons and chemotherapy drugs, but it cannot tell us whether and when to use them. As we saw in the last chapter, science cannot ground the belief that human beings should be valued equally.
