Sontag walked at the latest edges of world culture.   Seriousness was one of Sontag’s lifelong watchwords(格言),but at a time when the barriers between the well-educated and the poor-educated were obvious,she argued for a true openness to the pleasures of pop culture.In “Notes on Camp”,the 1964 essay that first made her name ,she explained what was then a little-known set of difficult understandings, through which she could not have been more famous .“Notes on Camp”,she wrote,represents“a victory of ‘form’over‘content’,‘beauty’over‘morals’”.    By conviction（信念）she was a sensualist（感觉论者）, but by nature she was a moralist （伦理学者）,and in the works she published in the 1970s and 1980s , it was the latter side of her that came forward. In Illness as Metaphor —published in 1978, after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities（被压抑的性格）, a concept that effectively blamed the victim for the disease. In fact , re-examining old positions was her lifelong lifelong habit.   In America,her story of a 19th century Polish actress who set up a perfect society in California, won the National Book Award in 2000.But it was as a tireless, all-purpose cultural view that she made her lasting fame.“Sometimes,”she once said ,“I feel that, in the end, all I am really defending …is the idea of seriousness, of true seriousness.”And in the end ,she made us take it seriously too. 71.The underlined sentence in paragraph 1 means Sontag_________.
