In America

Susan Sontag's In America, which chronicles the travails of a late-19th-century actress, shows Sontag in top time-travelling form and illuminates her motives for glancing so persistently backward. "Almost everything good seems located in the past", she notes in a first-person prologue, "perhaps that's an illusion, but I feel nostalgic for every era before I was born; and one is freer of modern inhibitions, perhaps because one bears no responsibility for the past". There's nothing, it seems, like the age of innocence--a golden moment before we moderns had the curse of self-consciousness brought down on our heads.
