Antonio "Toni" Negri is an Italian Marxist sociologist and political philosopher, best known for his co-authorship of Empire, and secondarily for his work on Spinoza.
“Throughout the world what remains of the vast public spaces are now only the stuff of legends: Robin Hood’s forest, the Great Plains of the Amerindians, the steppes of the nomadic tribes, and so forth… Rousseau said that the first person who wanted a piece of nature as his or her own exclusive possession and transformed it into the transcendent form of private property was the one who invented evil. Good, on the contrary, is what is common.”
