On Dialogue embraces what might be called the generous ways of thinking - metaphor, paradox, ambiguity, copia - ways that lead to multiplicity and diversity of ideas. In its broadest implications, Grudin's work is about the nature of the self and its place in society. Grudin celebrates the paradox that self-transcendence can lead to greater connection with others and ultimately to greater self-knowledge. On Dialogue, true to its own nature, is a book not easily categorized: of great importance to the academic specialist in philosophy and cognitive studies, it is also a practical and pleasurable resource for the general reader.
