Beginning with her experience as a medical actor who was paid to act out symptoms for medical students to diagnose, Leslie Jamison's visceral and revealing essays ask essential questions about our basic understanding of others: How should we care about each other? How can we feel another's pain, especially when pain can be assumed, distorted, or performed? Is empathy a tool by which to test or even grade each other? By confronting pain―real and imagined, her own and others'―Jamison uncovers a personal and cultural urgency to feel. She draws from her own experiences of illness and bodily injury to engage in an exploration that extends far beyond her life, spanning wide-ranging territory―from poverty tourism to phantom diseases, street violence to reality television, illness to incarceration―in its search for a kind of sight shaped by humility and grace.
