We are surrounded by the voices of authority, few of which are even remotely in a position to advise us.
Look at the means by which we are advised - television, for many, the most absurd. Every science officer on the USS Enterprise and Voyager have at one time or another been paid to voice-over science shows - 7 of 9, Geordi, and Spock, absurd that they are in any way qualified - as actors, yes, as representatives of science or reason, no, and yet it's an inane formula repeated time and time again, their voices alone, from having played fantasy characters in fantasy "science" fiction movies set in the fantasy future is enough to lend credibility to whatever "science idea" you're trying to promote. It's ludicrous.
Consider celebrity, every celebrity having used their elevated status to advise us on issues of health, religion (think Tom Cruise...), ethical treatment of animals, vegetarianism, you can't quote the cause that some celebrity hasn't thrown their status and presumed expertise behind to endorse.
There's politics, being a politician - an elected position with no formal qualifications whatsoever (whatever qualifications are incidental, not required), yet upon achieving office they are now authority figures that not only advise but enforce policies on morality, crime, environment, taxation and business. The lately dethroned Harper is one such example; from a background in economics he created and enforced policies on immigration, censorship, environment, etc., many with a devastating legacy and effect.
And there's wealth - possession of which alone is enough for many people to consider you not only an authority on wealth, but on happiness, family values, charity, politics and spirituality.
None of these "authorities" are even slightly credible, yet their voices abound and clamor to be heard, very often over those better qualified to advise or promote the cause. Think Donald Trump.
This is a segue into another argument I'll be making shortly, in the meantime I'd suggest you reject all authority until you've entirely done your research. Or, at the very least, question it heavily..
