Virtue and the Common Good: Hermeneutic Foundations of aš-Šāṭibī's Ethical Philosophy arose as a response to the urgent need for epistemological research on the hermeneutic foundations of Islamic ethical and moral theory that has resulted from the current period of upheaval in Islamic theology. Choosing a late-medieval work of legal theory, namely, Abū Isḥāq Ibrāhīm ibn Mūsā aš-Šāṭibī's (d. 790/1388) al-Muwāfaqāt, as the point of departure, locates this study's discussion methodologically and theoretically in the genealogical process of re-reading and reconstructing Islamic thinking in modernity from the perspectives of contemporary philosophy of ethics. Thus, profoundly reflecting on modern understanding and interpretation of fundamental theological concepts in the Islamic legal- and moral theory becomes unavoidable.
