While in contemporary culture we tend to resort to a single, if broadly defined, range of discourse for the results of systematic thought about public matters of the social order, this is not the case in Rabbinic Judaism. Judaism's authoritative documents set forth the entire structure of belief and system of behavior in two distinct modes of discourse, Halakhic and Aggadic, or broadly construed, statements of law and lore. Theology in Action shows how the Talmud of Babylonia (a.k.a., the Bavli) account of normative action sets forth in a dual discourse the single, coherent theology of Rabbinic Judaism.
