The twentieth century Russian philosopher and literary theorist Mikhail Bakhtin wrote extensively on the concept of dialogue. Although Bakhtin's work took many different directions over the course of his life, dialogue always remained the "master key" to understanding his worldview.[1] Bakhtin described the open-ended dialogue as "the single adequate form for verbally expressing authentic human life". In it "a person participates wholly and throughout his whole life: with his eyes, lips, hands, soul, spirit, with his whole body and deeds. He invests his entire self in discourse, and this discourse enters into the dialogic fabric of human life, into the world symposium."[2]
