Hermeneutics is a method of textual analysis that focuses on interpreting qualitative data, especially texts, to aid human understanding. It involves understanding parts of a text in relation to the whole by iterating between interpretations. Key concepts in hermeneutics include historicity, the hermeneutic circle, prejudice, and the distanciation of texts from their authors over time. Hermeneutics is useful for ordering, explaining, and interpreting interviews, documents, and field notes in qualitative research to develop a deeper understanding.
