The document discusses several theoretical tools for critiquing discourses around quality and social change, including post-structuralist ideas from Michel Foucault on how power operates through discourse to construct social realities. It also discusses standpoint theory and the idea that oppressed groups can develop critical insights by understanding how the world is structured from their situated perspectives. Finally, it discusses Boaventura de Sousa Santos' concept of an "sociology of absences" which examines how certain alternatives are actively produced as non-existent through dominant logics and rationalities.
