«But to welcome divergent views is not to say that anything goes. There is a difference between accepting that there may be alternative interpretations of the same evidence and respecting a view for which there is no evidence simply because someone holds it. That difference is why the Friedman Institute is appropriate for a major university, and a school of homeopathy inappropriate even for a minor one».
