i had to look in the dictionary to understand it. (hehm)

"A condition in which numerous distinct ethnic, religious, or cultural groups are present and tolerated within a society.

The doctrine that reality is composed of many ultimate substances.

The belief that no single explanatory system or view of reality can account for all the phenomena of life."

PS. after i posted the text above i read that the italian white overalls movement has died out (two years ago i think). the leaders realized the movement was finished, it had reached its maturity (the genova demonstrations, where the one young man who was killed by the police was a part of that movement) and went back to where most movements go.
