Shaker's ... seems to forget that if this is an argument from anything, its an argument from breadth, as opposed to 'from authority' (something that he himself seems to rely on, despite appearing to criticise here).
Wrong. An argument from authority is lazily throwing in some big names and expecting the spectator to be impressed not with the strength of the arguments - the clarity and logical rigour of the thinking - but the mere fact that they're big names.
Clearly there are some occasions in life when not authority but
expertise is a perfectly right, proper and valid thing to invoke - the former flows from the latter, not vice versa. In "debating" with a creationist the knowledge of an evolutionary biologist is what you need; when trying to make the perfect sponge cake you'd be better off with Mary Berry than Steve Jones. That's not relying on authority because the worth of such people isn't predicated on eminence but on expertise - people who achieve eminence in their respective fields do so on the basis of that expertise and not vice versa, which is precisely where the argument from authority gets it arse-backwards.
Nobody, no matter how eminent, has any expertise in gods. Certainly there are some forlorn individuals who have expertise in the non-subject known as theology (currently being discussed on another thread), but that's merely "expertise" in other people's beliefs and opinions about gods ... a fatuous and forlorn endeavour indeed.
From my point of view, its nice to hear an eminintly sensible scientist, albeit an atheist
That's the vast majority of them by a long way, then
