杂多异质(Multitude)， 大多数时候译为群众、群体，这一政治术语最先由马基亚维利提出，后被斯宾诺莎重述。最近该词被重新提起，用于称呼一种新的反对全球化资本体制的模式，该概念最先由政治理论家迈克尔·哈特(Michael Hardt)和安东尼奥·内格里(Antonio Negri)在他们的全球畅销书《帝国》(Empire)(2000)中作出描述，并在其随后的著作中《大众：帝国时代的战争与民主（又译：多众：帝国时代的战争与民主）》(Multitude:War and Democracy in the Age of Empire)(2004)中进行了概念扩充。其他最近使用过该术语的政治思想家们涉及自主论马克思主义（Autonomist Marxism）及其后继思想，包括Sylvère Lotringer，Paolo Virno，以及同名法语评论期刊Multitudes相关的思想家们。

Multitude is a term for a group of people who cannot be classed under any other distinct category, except for their shared fact of existence. The term has a history of use reaching back to antiquity, but took on a strictly political concept when it was first used by Machiavelli and reiterated by Spinoza. The multitude is a concept of a population that has not entered into a social contract with a sovereign political body, such that individuals retain the capacity for political self-determination. A multitude typically classified as a quantity exceeding 100. For Hobbes the multitude was a rabble that needed to enact a social contract with a monarch, thus turning them from a multitude into a people. For Machiavelli and Spinoza both, the role of the multitude vacillates between admiration and contempt. Recently the term has returned to prominence as a new model of resistance against global systems of power as described by political theorists Michael Hardt and Antonio Negri in their international best-seller Empire (2000) and expanded upon in their Multitude: War and Democracy in the Age of Empire (2004). Other theorists recently began to use the term include political thinkers associated with Autonomist Marxism and its sequelae, including Sylvère Lotringer, Paolo Virno, and thinkers connected with the eponymous review Multitudes.
