Utopia can today be understood in two opposing ways. First, there are the positive utopias, ideas and concepts of a better world in which work, wealth and happiness are evenly distributed. Such utopias often refer to an "outside", to a happy place beyond reality. Criticising such a transcendental notion of utopia, Negri has suggested that Empire, a form of power which, in a globalised world, has no central site any longer, is itself a "non-place", a "u-topos". However, the site of this power is immanent in this world, as are the alternatives to Empire. The "multitude" is the acting subject of this "worldly utopia". Introduction and moderation by Thomas Atzert. Antonio Negri is a philosopher and writer. His latest publications are Time for Revolution (2003) and together with Michael Hardt, Empire (2000). For many years, Negri has been one of the most influential thinkers of the condition of globalisation. Thomas Atzert is a journalist and translator. He translated Empire from Hardt/Negri into German.
