This chapter examines Conservative Judaism and ethic. Changing what Jews do and altering the reasons why they should do things differently was not an exclusively Reform endeavour; Conservative Judaism has also instituted innovations, especially since World War II. These changes are most evident in Conservative liturgy as well as in halakhic positions vis-à-vis women, homosexuality, and mamzerut (bastardy). Conservative thinkers and scholars of Jewish law, however, have taken diverse approaches as to how and when to make such changes, and so one cannot articulate a single “Conservative theory” of Jewish ethics. The chapter presents the author's own approach in contrast to those of some of the other representatives of Conservative Judaism, whose theories and legal rulings are discussed.
