Priest On the Say-so of Experts
[N]o one is an expert in many areas, and we all have to accept things on the say-so of experts in some areas. If someone believes that it is irrational to believe contradictions on the basis of experts in logic and philosophy, their belief is not irrational. The charge of irrationality is levelled against people who ought to have known better.
