paradox
ab intra silentio vera
Without any examples to look at, I'd say I can't see what your concern is about.
I see nothing that indicates a move towards a return of the High priest scenario.
There is no room or role for secretive authoritative leadership in either Science or philosophy. Religion is still hung up on that crap, but that's old religion. And new religion doesn't exist yet in recognizable form. But there is no way as trends develop that it will bear any resemblance to the old pyramidal command structures of the past.
Actually looks to be racing in the opposite direction.
Do you have any examples of what you are thinking of?
Yes, understandably so, I know. I mentioned in my post a perfect example of what I was getting at, modern mainstream Astronomy/Cosmology. The Office(s) of High Priest is actually quite active and doing well, although the title has changed significantly, and usually administered under the auspices of major Universities or institutions. There are so many experiences with the current status quo related by professionals working in the field, across so many papers, sites, etc I wouldn't know where to tell you to start looking. Well, actually, I'd probably go with starting here http://www.holoscience.com/synopsis.php and then just do a little further researching into alternate views to Astronomy's current acceptance, in the name of science, of very strange metaphysical ideas of "the big bang," "black holes," "dark matter," "dark energy," "magnetic reconnection," "frozen-in lines of force," etc. etc.
I'm not the best at expressing it so I can also understand if it just sounds like so much tinfoil-hattery, but check around if it actually interests you; there are others so much more eloquent and versed in the subject(s) than I.
