Tóm tắt	Textual criticism is a systematic philological method for identifying, comparing, and evaluating variant readings across multiple manuscript or print witnesses of a text in order to reconstruct the most accurate version of the original — or the author's intended — text. Applied since antiquity to classical, biblical, and literary works, it remains the foundational editorial method in classical studies, biblical scholarship, medieval studies, and critical editing of literary works.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.
