Confessions of a mask

The theory of self-deception was foreshadowed by the sociologist Erving Goffman in his 1959 book The Presentation of the Self in Everyday Life, which disputed the romantic notion that behind the masks we show other people is the one true self. No, said Goffman; it's masks all the way down. Many discoveries in the ensuing decades have borne him out.
