Drawing from the works of Plato and more contemporary philosophers such as Bakhtin, Buber, Taylor, and Gadamer, On Dialogue explores the necessity of dialogue to being. Author Dmitri Nikulin argues that dialogue is not just a form of communication, but it is the very conditio humana. Nikulin provides a systematic account of dialogue and its role in philosophy, literature, and oral discourse. Exploring the notion of human unfinalizability in dialogical communication, which does not always come to a consensus but is always carried on further in order to express one's self as one's personal other, On Dialogue argues that the human is a dialogical being in perpetual conversation with the other. By offering clues a better understanding of the being, Nikulin's work makes a significant contribution not only to the field of philosophy, but also to the study of anthropology and ontology.
