Ethics plays an essential role in the philosophical framework of Abū Bakr al-Rāzī. Although most of his philosophical works have become extinct, two surviving works serve as primary sources for understanding his ethical theory. Although sharing certain foundational principles, these two works diverge in terms of ethical standards and exhibit distinct logical approaches to ethics, a facet that has largely remained unexplored within contemporary scholarly discourse. I aim to extract and reconstruct both of his ethical decision-making systems by shedding light (...) on the place of ethics in his philosophy, explaining the interconnection of the two ethical frameworks, reconstructing both of these ethical systems, and finally presenting them in patterns.
