Abstract
The aim of this paper is to show how the dialogical form is an essential structure of the Platonic texts in which the interrogative form is the very form of philosophy. According to the intentio auctoris, the dialogues can change the lives of their readers and this can only happen thanks to the readers’ internalization of the dialogical form as an interrogative structure. Like Socrates’ interlocutors in the dialogues, readers with the dialogues, can change their live making it coherent with their own thoughts examined through the philosophical discourse. This form of coherence is the only possibility of virtue, and therefore of happiness.
