“The danger they have been taught to fear from absolutism is not error but intolerance. Relativism is necessary to openness; and this is the virtue, the only virtue, which all primary education for more than fifty years has dedicated itself to inculcating. Openness— and the relativism that makes it the only plausible stance in the face of various claims to truth and various ways of life and kinds of human beings —is the great insight of our times. The true believer is the real danger. The study of history and of culture teaches that all the world was mad in the past; men always thought they were right, and that led to wars, persecutions, slavery, xenophobia, racism, and chauvinism. The point is not to correct the mistakes and really be right; rather it is not to think you are right at all.”
