It is always hard to make a rule about the claim of the amateur to contradict the expert. One test, which would by itself cart away a great deal of lumber, is the rule that none is a specialist outside his speciality. In magazines and such modern arenas this truism is often oddly disregarded [...] But there is yet another line along which the conclusions of the expert may lawfully be tested by the amateur. And these are the cases in which the expert actually asserts what the amateur is able from his own knowledge to deny. We are not bound to believe the Astronomer Royal when he disproves the sun in heaven; and though I may respect my doctor when he tells me I am dying, I shall differ from him if he tells me I am dead.
