 This attempt to satisfy the conditions for a good instance of argument from authority fails because it produces a number of problematic premises. Other experts disagreed (and continue to disagree) with Einstein’s suggestion that it is a mistake to stockpile nuclear weapons. More fundamentally, the proposed argument is founded on too loose an account of nuclear weapons as a domain of expertise. Einstein is a renowned expert on nuclear physics but this it does not make him an expert on the social and political issues raised by nuclear weapons. This is something that a convincing version of the argument would have to establish.
