I'll be "wise" and say I don't know if "secret societies" exist.
Well, that wasn’t worded just right, actually... :-)
I should have been a lot more precise and said that knowledge can’t be kept hidden by so-called secret societies to the point where no one will ever know, except those “special members” of those so-called secret societies...
Eventually others outside of any such group will also know any “hidden knowledge” too...
That’s what I meant by not believing in secret societies... (if you understand what I’m talking about now... I hope...).
