Regarding the Pain of Others is a 2003 book-length essay by Susan Sontag, which was nominated for the National Book Critics Circle Award. It was her last published book before her death in 2004. It is regarded by many to be a follow-up or addendum to On Photography, despite the fact that the two essay collections convey Sontag's radically different opinions about photography. The essay is especially interested in war photography. Using photography as evidence for her opinions, Sontag sets out to answer one of the three questions posed in Virginia Woolf's book Three Guineas, "How in your opinion are we to prevent war?"
