Postmodern Marxists argue that ideology is a way of thinking about the world that is shaped by power relations. This means that ideology is not simply a set of beliefs that people hold, but rather a way of thinking that is produced and reproduced through the circulation of power.

Michel Foucault, Jean-François Lyotard, Fredric Jameson, and Slavoj Žižek are all key figures in postmodern Marxism.
