> The science and societies of the past were always flawed, and mistaken, they just didn't know better. The science and societies of the present never are wrong or flawed in their thinking. That's also the reasoning the communists and the National Socialists used in their reasoning; turns out they were faced with the same problems their predecessors had to deal with but they didn't really have better solutions. In the end the people paid because it was more important to save face than to admit being wrong.
