Eliezer says that authority is not 100% irrelevent in an argument. I think this is true because 100% of reliance on authority can't ordinarily be removed. Unless the issue is pure math or directly observable phenomena. But removal of reliance on a particular individual's authority/competence/biological state etc. is one the first steps in achieving objective rationality.
