No. But they're brains (which prevades the mind) does exist within the universe, and contained in this mind is the imagined pink elephants. But do the pink elephants exist? Yes they exist as imagined creatures in the mind of the imaginator.
Depends on what you mean by "Power". If enough people believe that pink elephants exist. Then does that mean they do? No...they don't except in the imaginations of those who believe it.
But YES: if by POWER you mean the ability to change human civilization, or policy, or dispersal of wealth. Collective imagination can be very powerful in this regard.IMO Peace be with you.
if everybody believes that something exists, then basically it does exist.
So what happened during the Y2K change over? Nothing happened. I do not agree with this point....I do not think that one person believing or a million will make a pink elephant appear.
My apologies if I inadvertantley insulted any work you may have contributed during the Y2K..I was refering more to the "doomsdayers" and apocalyptic nonsense that was bringing out all sorts of fruitcakes with all manner of EVENTS supposedly going to take place. The Millenium passed with no end of the Earth, or Jesus making a public appearance.
