"I have come to think […] the character called "I" in a work of journalism […] is unlike all the journalist's other characters in that he forms the exception to the rule that nothing may be invented: the "I" character in journalism is almost pure invention. Unlike the "I" of autobiography, who is meant to be seen as a representation of the writer, the "I" of journalism is connected to the writer only in a tenuous way—the way, say, that Superman is connected to Clark Kent. The journalistic "I" is an overreliable narrator, a functionary to whom crucial tasks of narration and argument and tone have been entrusted, an ad hoc creation, like the chorus of Greek tragedy. He is an emblematic figure, an embodiment of the idea of the dispassionate observer of life. Nevertheless, readers who readily accept the idea that the narrator in a work of fiction is not the same person as the author of the book will stubbornly resist the idea of the invented "I" of journalism; and even among journalists, there are those who have trouble sorting themselves out from the Supermen of their texts."
