Psychology of Purity

Catalog description

Any moral and religious systems tell us to keep a “pure heart,” and that immoral acts “pollute” our souls. We dislike dirty plays and dirty players in sports, and we keep our children away from dirty movies. We are also motivated to maintain purity in the less metaphorical sense—most cultures have norms about keeping bodies and living spaces clean. We even have an emotion—disgust—that seems especially attuned to certain kinds of dirtiness (such as bodily fluids and rotten food). The concept of purity, then, appears to be a deep aspect of human psychology—from the basic motivation to maintain physical purity, to the metaphors of purity and cleanliness that feature heavily in morality and religion across cultures. In this course we will look at the psychology of purity by reading widely on the topic, including historical, religious, anthropological, and psychological topics that center on purity in both the physical and moral/spiritual sense. Our aim will be to understand how this basic notion of pure/impure or clean/dirty has come to shape our psychology and our culture.
