Critical theory is a philosophical and sociological approach that focuses on analyzing and critiquing power structures and systems of domination in society. It seeks to uncover and challenge the underlying assumptions and ideologies that perpetuate inequality, oppression, and injustice. Critical theorists aim to bring about social change by raising awareness of these issues and advocating for a more equitable and democratic society. Key concepts in critical theory include questioning authority, challenging dominant narratives, and promoting individual and collective liberation. Some prominent figures in critical theory include Theodor Adorno, Max Horkheimer, Herbert Marcuse, and Jürgen Habermas.
