The Jewish legal tradition has much to say about how we are to act. But what about how we are to feel? Do emotional states, in and of themselves, have significance in halakha? In this course, we will explore this question, examining some common human emotions such as (e.g. joy and shame) in light of halakhic sources drawn from the Talmud through the responsa literature. We will also consider somewhat more elusive emotional states that have implications in Jewish law, such as oneg (pleasure), tza'ar (pain) and yishuv da'at (peace of mind).
