Susan Sontag was one of those writers who seemed to change the temperature of every room she entered.
Part of that came from style. She wrote criticism with the pressure and finish of literature. Part of it came from range. Photography, illness, fascism, fiction, cinema, war, camp, moral witness, interpretation itself: she kept choosing subjects that forced culture to explain what it thought it was doing. And part of it came from persona. Sontag was not only a public intellectual; she was one of the few critics in American life who looked and sounded like a public event.
She made interpretation fight with experience.
She became famous by attacking the habits of criticism
Britannica still identifies "Notes on 'Camp'" and Against Interpretation as the works that first made Sontag a major presence, and that remains the right place to begin. In those essays she was not simply offering opinions about art. She was challenging the reflex that treats art mainly as coded content waiting to be decoded.
That challenge is the center of her early importance. Sontag argued that too much interpretation flattens the sensual force of art. Critics, in her view, often substitute explanation for encounter. The provocation worked because it hit a real nerve. Mid-century intellectual culture loved seriousness, but it often loved seriousness in the form of mastery. Sontag came along and asked whether the need to master a work had become a way of not feeling it.
She did not reject thought. She rejected the kind of thought that arrives too quickly with a knife.
She expanded criticism without making it smaller
What is striking now about Sontag's body of work is how much of it refuses the border between high and low culture.
Britannica notes that she wrote on theatre, film, photography, aesthetics, and political violence with the same grave attention. The Jewish Women's Archive article pushes this further, describing her as a champion of a "new sensibility" that challenged the distinction between the serious and the frivolous. That is one of the best ways to describe her method. Sontag did not democratize culture by becoming casual. She democratized it by treating more of culture as worthy of exacting thought.
This is why she remained so influential. She could write about camp, illness, and atrocity without reducing them to the same thing, yet she also insisted that they belonged within one intellectual world. Criticism, for her, was not a fenced specialty. It was a way of attending to the conditions of modern life.
She made criticism feel expansive rather than merely supervisory.
Illness, photography, and war gave her a harsher authority
Sontag's later work deepened rather than softened her seriousness.
On Photography helped change how readers thought about image culture, spectatorship, and the ethics of looking. Illness as Metaphor and AIDS and Its Metaphors attacked the moral language societies attach to sickness. Regarding the Pain of Others returned to images, but under the pressure of atrocity and war. Across these books Sontag kept asking some version of the same question: what happens when representation begins to substitute for contact, or when public language begins to moralize experience until the experience itself disappears?
The Jewish Women's Archive also reminds readers that her fascination with images of suffering was tied in part to seeing photographs of the Holocaust as a child. That helps explain the unusual force of her writing on pain, witness, and spectacle. She was never innocent about the seductions of looking, but neither was she willing to give up on looking altogether.
That tension gave her work its bite.
Her Jewishness was real, if often complicated
The Jewish Women's Archive portrays Sontag as both deeply marked by Jewish reference points and persistently resistant to being claimed by any narrow identity category. She had little religious upbringing, rarely wrote directly about Jewish life, and often insisted on universalism over belonging. Yet Jewish history, Holocaust memory, Israel, and arguments inside Jewish intellectual culture all remained part of her orbit. Her 2001 Jerusalem Prize appearance became a public flashpoint precisely because she could neither be cleanly claimed nor cleanly detached.
That refusal is important. Sontag did not want inherited identity to be the final interpretive key to her work. But she also could not step outside history.
She lived inside that contradiction rather than resolving it.
Why she still matters
Susan Sontag matters because she turned criticism into a contest over what it means to be fully awake to art, politics, and suffering.
She insisted that culture was not ornamental and that criticism was not clerical. She wrote with a severity that could be exhilarating or infuriating, but never trivial. She kept forcing readers to ask whether explanation was sharpening their relation to experience or draining it. She also made the critic visible as a moral and aesthetic actor, not just a reviewer of other people's creations.
That combination remains rare. Most public criticism today tilts toward fast judgment, niche fluency, or ideological sorting. Sontag wanted something harder. She wanted intelligence with appetite, moral seriousness without piety, and style without surrender.
She made interpretation fight with experience, and she never let either side win too easily.
