Anger, fear, joy, sadness, disgust, surprise, envy, pride, jealousy, love, grief -- without emotions our experience of the world would be flat and grey, void of the upheavals, accelerations, and turns that make the journey of life so exciting. But what are emotions? What kind of mental state are they? Are there universal emotions, or are all emotions culturally-relative? What does it mean to feel fear -- as opposed to think -- that something is scary? How can we know that someone is envious? Is disgust always bad? Can joy be inappropriate? In this course students explore these and many other questions concerning the metaphysics, epistemology, phenomenology, value, and rationality of emotions. Readings are drawn from a variety of sources: classical philosophical texts, contemporary articles in philosophy and psychology, popular culture, and literature.
