Deconstruction argues that language, especially ideal concepts such as truth and justice, is irreducibly complex, unstable, or impossible to determine. Many debates in continental philosophy surrounding ontology, epistemology, ethics, aesthetics, hermeneutics, and philosophy of language refer to Derrida's beliefs. Since the 1980s, these beliefs have inspired a range of theoretical enterprises in the humanities, including the disciplines of law, anthropology, historiography, linguistics, sociolinguistics, psychoanalysis, LGBT studies, and feminism. Deconstruction also inspired deconstructivism in architecture and remains important within art, music, and literary criticism.
