I enjoyed watching Hillary C. extol truth and reason in her Wellesley commencement speech, and denounce the idea of alternative facts. But then she went on, in characteristic modern style, to commend “diverse viewpoints”. But these are incompatible ideas: there is only one set of truths (and many sets of falsehoods) because reality is only one way. We should not welcome “diverse viewpoints” on the shape of the Earth or the correctness of evolution. The notions of truth and reason inevitably generate an elite of believers–those who believe the truth and employ reason. The rest are just wrong. I don’t welcome Trump’s beliefs about crowd sizes.
