"conventional terms such as service work, intellectual labor, and cognitive labor all refer to aspects of immaterial labor, but none of them captures its generality. As an initial approach, one can concieve immaterial labor in two principle forms. The first for refers to labor, that is primarily intellectual or linguistic such as problem solving, symbolic and analytical tasks, and linguistic expressions. This kind of immaterial labor produces ideas, symbols, codes, texts, linguistic figures, images and other such products. We call the other principle form of immaterial labor "affective labor". Affective labor, then, is labor that produces or manipulates affects such as a feeling of ease, well-being, satisfaction, excitement, or passion."

“A second part of criticisms , which relate closely to the first, focus on the economic conception of the multitude. … "You are really against the workers!" … Industrial labor has been displaced from its hegemonic position over other forms of labor by immaterial labor, which now tends to transform all sectors of production and society itself in line with its qualities. Industrial workers remain important, then, but within the context of this new paradigm. Here arises, then, but within the second criticism of this pair, that our argument of hegemony of immaterial labor replaces the old vanguard of industrial workers with a new vanguard of immaterial workers - Microsoft programmers leading us on the shining path. "You are just postmodern Leninist in sheep's clothing!" they cry. No, the hegemonic position of a form of production in the economy should not imply any political hegemony. Our argument about the hegemony of immaterial labor and the becoming common of all forms of labor is aimed instead at establishing that contemporary conditions tending to form a general communication and collaboration of labor that can be the basis of the multitude.”

“The old form of trade union, which was born in the nineteenth century and aimed primarily at negotiating wages for a specific trade is no longer sufficient. First of all, as we have been arguing, the old trade unions are not able to represent the unemployed, the poor, or even the mobile and flexible post-Fordist workers with short term contracts, all of whom participate actively in social production and increase social wealth. Second, the old unions are divided according to the various products and tasks defined in the heyday of industrial production - a miners' union, a pipefitters' union, a machinists' union and so forth. Today, insofar as the conditions and the relations of labor are becoming common, these traditional divisions no longer make sense and serve only as an obstacle. Finally the old unions have become purely economic, not political, organization.”

“We are by no means opposed to the globalization of relationships as such—in fact, as we said, the strongest forces of Leftist internationalism have effectively led this process. The enemy, rather, is a specific regime of global relations that we call Empire.”

“The poor are thought to be dangerous, either morally dangerous because they are unproductive social parasites - thieves, prostitutes, drug addicts, and the like - or potentially dangerous because they are disorganized, unpredictable, and tendentially reactionary. In fact the term lumpenproletariat has functioned for times to demonize the poor as a whole. … The industrial reserve army is a constant threat hanging over the heads of the existing working class because, first of all, its misery serves as a terrifying example to workers of what could happen to them, and, second, the excess supply of labor it represents lowers the costs of labor and undermines workers' power against employers .”

“In fact, the old Marxist distinctions between productive and unproductive labor, as well as that between productive and reproductive labor, which were always dubious, should now be completely thrown out.”

“Multitude is a class concept. … Class is determined by class struggle. There are, of course, in infinite number of ways that humans can be grouped into classes - hair color, blood type, and so forth - but the classes that matter are those defined by the lines of collective struggle. Race is just as much a political concept as economic class is in this regard. … Class is a political concept, in short, in that a class is and can only be a collectivity that struggles in common.”
