Dialogue (n.) in the Socratic form already presupposes beings who have decided for discourse and accepted its rules, whereas teaching leads to logical discourse without flattery or seduction.
Dialogue (n.) is not the first form of language; before it, language is witnessing — a bearing witness of the infinite to the one I open to infinitely.
Dialogue (n.) cannot be summed up by an absolute observer behind the scenes who would have the last word — that would turn it into an ontology in which the Said rules the Saying.
Dialogue (n.) as reciprocal exchange of ideas hides the essence of language — the irreversibility between me and the other, who is not a Thou but a You.
Dialogue (n.) lives off its own openness and the presence of the interlocutor; unlike medieval disputation, its impossibility of concluding is its life.
