 We can't see the whole of reality, or at least social reality, by ourselves. We will always need the eyes of others to help us see into our blind spots. The extent that we do not allow others in is largely the extent that we are deluded. Be wary of being too attached to any idea. If you don't want to put it up for debate, then maybe you have an agenda going. Beware of collective delusions too. The power of people to create moral panic is astounding. The stupidity that can come out of groups is well documented. Idiocy can be contagious. Don't think the human mind works logically, or the world either for that matter. Beware of the obvious choice; it could be a snare for fools
