Heh, I myself used to 'call' almost everything arty that I liked "psychedelic". It was the first label that sprung to my mind. But it's much better to describe the music or image or whatever more analytically. See this relevant discussion here: http://asides-bsides.blogspot.com/2009/03/secrets.html ( U can skip the initial text, just read the comments )
Well i used to believe something like that , but that's overly optimistic. Psy/Goa music doesn't magically make people PLUR.
Any kind of people can be "plur" at times.
I agree that social conditioning plays a major role, but apart from that, there are archetypes,there are insticts, there are psychological mechanisms we have. Why did the system end up like this anyways? It's not a separate entity from us, it consists of people.
