Jewish ethics stands at the intersection of
Judaism and the Western philosophical tradition of
ethics. Like other types of
religious ethics, the diverse literature of Jewish ethics primarily aims to answer a broad range of moral questions and, hence, may be classified as a normative ethics. For two millennia, Jewish thought has also grappled with the dynamic interplay between
law and ethics. The tradition of
rabbinic religious law (known as
halakhah) addresses numerous problems often associated with ethics, including its semi-permeable relation with duties that are usually not punished under law.
Jewish ethics may be said to originate with the Hebrew Bible, its broad legal injunctions, wisdom narratives and prophetic teachings. Most subsequent Jewish ethical claims may be traced back to the texts, themes and teachings of the written Torah.
In early rabbinic Judaism, the oral Torah both interprets the Hebrew Bible and delves afresh into many other ethical topics. The best known rabbinic text associated with ethics is the non-legal Mishnah tractate of Avot (“forefathers”), popularly translated as “Ethics of the Fathers”. Similar ethical teachings are interspersed throughout the more legally-oriented portions of the Mishnah, Talmud and other rabbinic literature. Generally, ethics is a key aspect of non-legal rabbinic literature, known as aggadah. This early Rabbinic ethics shows signs of cross-fertilization and polemical exchange with both the Greek (Western philosophical) ethical tradition and early Christian tradition.
In the medieval period, direct Jewish responses to Greek ethics may be seen in major rabbinic writings. Notably, Maimonides offers a Jewish interpretation of Aristotle (e.g., Nicomachean Ethics), who enters into Jewish discourse through Islamic writings. Maimonides, in turn, influences Thomas Aquinas, a dominant figure in Catholic ethics and the natural law tradition of moral theology. The relevance of natural law to medieval Jewish philosophy is a matter of dispute among scholars.
