I’ve come across these two terms quite often, so whats the difference?

Dialectic: two competing perspectives meet and one gains primacy, basically handle disagreement and provides a sense of progress. Conflict => agreement (connection to Hegel: In Hegel’s work, dialectics is the method of epistemological cognition opposed to metaphysics)

Dialogic: various approaches coexist and are relativistic, it all depends on circumstances  and what is the desired effect of interaction (e.g. emotions and ethics) à no urgency of “best” idea
