About this episode

This episode explores the historical and cultural shifts in the perception of breasts as erotic objects, featuring sociologist Sarah Thornton.

You might think that breasts are inherently sexual and that humans have always eroticized them. Historically, however, breasts haven’t always been seen this way, and even today, breasts are barely sexualized in some cultures. In today’s episode, we’re looking at the fascinating story behind how breasts became eroticized, and how the cultural meaning of breasts has changed over time. My guest is Sarah Thornton, a sociologist, non-fiction writer, and author of four critically acclaimed books. Thornton’s most widely read book is Seven Days in the Art World, which is translated into over 20 languages. Her latest is titled, Tits Up: The Top Half of Women’s Liberation, which explores the significance of breasts across radically different social worlds. Some of the specific topics we explore include: How did decoupling breasts from feeding make them more erotic? What role did infant formula play in that shift? Historically, was breast sexualization partly a privilege of wealth? How do culture and concealment shape what we eroticize? Why is the nipple where we draw the line?
