If the moral shortcomings of our ancestors require us to despise them as vile , to reject the traditions these vile people valued and helped develop, and to renounce the moral ideals of the present which developed from these despised traditions — doesn’t consistency require us also to despise past generations of scientists, scientific method and current science, since the history of science is a story of successive delusion and malpractice? To satisfy the high standards we hold today, we need to find cultures founded from the very beginning on empathy, kindness  and equality, and we also need to find an intellectual traditions with a better track record of knowing what is true and what is not true.
