This document summarizes and critiques Jurgen Habermas' theory of communicative action. It discusses Habermas' views on understanding, rupture, crisis, translation, and transformation. It also presents alternative perspectives that truth is intersubjective rather than universally understood, and that rupture is an inherent part of life rather than something to be solved through knowledge. The document critiques Habermas' view of crisis as caused by lack of rationality, and presents an alternative view of morality as existential-ontological rather than deontological. It concludes by noting remarks on Hegel and a quote from Marx about force deciding between equal rights.
