Montaigne was the first writer to create literature that deliberately worked in this way, and to do it using the plentiful material of his own life rather than either pure philosophy or pure invention. He was the most human of writers, and the most sociable. Had he lived in the era of mass networked communication, he would have been astounded at the scale on which such sociability has become possible: not dozens or hundreds in a gallery, but millions of people seeing themselves bounced back from different angles.
