Comment accroître la valeur d’un texte de théâtre ?

How can the formal structure and the literary devices of a text increase its objective value? Why would this text not be as good otherwise? We will take the case of scene 2 from act II of Racine’s Phèdre, when Hippolytus declares his love to Aricia. Paradoxically, this revelation occurs late as the beginning of the scene deals with political issues ; in addition, Hippolytus did not have the intention of declaring his love to Aricia: it is the words uttered by Aricia that lead him to do so. How does this process work? How does it enrich the text? What effects does it produce?
