Poststructuralism in the context of Structural linguistics

Jürgen Habermas (UK: /ˈhɑːbərmæs/ HAH-bər-mass, US: /-mɑːs/ -⁠mahss; German: [ˈjʏʁɡn̩ ˈhaːbɐmaːs] ; born 18 June 1929) is a German philosopher and social theorist in the tradition of critical theory and pragmatism. His work addresses communicative rationality and the public sphere.

Associated with the Frankfurt School, Habermas's work focused on the foundations of epistemology and social theory, the analysis of advanced capitalism and democracy, the rule of law in a critical social-evolutionary context, albeit within the confines of the natural law tradition, and contemporary politics, particularly German politics. Habermas's theoretical system is devoted to revealing the possibility of reason, emancipation, and rational-critical communication latent in modern institutions and in the human capacity to deliberate and pursue rational interests. Habermas is known for his work on the phenomenon of modernity, particularly with respect to the discussions of rationalization originally set forth by Max Weber. He has been influenced by American pragmatism, action theory, and poststructuralism.

Difference is a key concept of philosophy, denoting the process or set of properties by which one entity is distinguished from another within a relational field or a given conceptual system. In the Western philosophical system, difference is traditionally viewed as being opposed to identity, following the Principles of Leibniz, and in particular, his Law of the identity of indiscernibles. In structuralist and poststructuralist accounts, however, difference is understood to be constitutive of both meaning and identity. In other words, because identity (particularly, personal identity) is viewed in non-essentialist terms as a construct, and because constructs only produce meaning through the interplay of differences (see below), it is the case that for both structuralism and poststructuralism, identity cannot be said to exist without difference.
