Contemporary Islamic philosophy revives some of the trends of medieval Islamic philosophy, notably the tension between Mutazilite and Asharite views of ethics in science and law, and the duty of Muslims and role of Islam in the sociology of knowledge and in forming ethical codes and legal codes, especially the fiqh (or "jurisprudence") and rules of jihad (or "just war").
