Postmodern International relations is an approach that has been part of international relations scholarship since the 1980s. Although there are various strands of thinking, a key element to postmodernist theories is a distrust of any account of human life which claims to have direct access to the "truth". Post-modern international relations theory critiques theories like Marxism that provide an overarching metanarrative to history. Key postmodern thinkers include Lyotard, Foucault and Derrida.
Criticisms
A criticism made of post-modern approaches to international relations is that they place too much emphasis on theoretical notions and are generally not concerned with the empirical evidence.
