The most incisive twentieth century students of language converge from different premises on the conclusion that language is the key creator of the social worlds people experience, and they agree as well that language cannot usefully be understood as a tool for describing an objective reality. For the later Wittgenstein there are no essences, only language games. Chomsky analyzes the sense in which grammar is generative. For Derrida all language is performative, a form of action that undermines its own presuppositions. Foucault sees language as antedating and constructing subjectivity. The “linguistic turn” in twentieth century philosophy, social psychology, and literary theory entails an intellectual ferment that raises fundamental questions about a great deal of mainstream political science, and especially about its logical positivist premises.

While the writers just mentioned analyze various senses in which language use is an aspect of creativity, those who focus upon specifically political language are chiefly concerned with its capacity to reflect ideology, mystify, and distort. The more perspicacious of them deny that an undistorting language is possible in a social world marked by inequalities in resources and status, though the notion of an undistorted language can be useful as an evocation of an ideal benchmark. The emphasis upon political language as distorting or mystifying is a key theme in Lasswell and Orwell, as it is in Habermas, Osgood, Ellul, Vygotsky, Enzensberger, Bennett, and Shapiro.
