An interlocutor in front of a usually minoritary audience, with a physical presence and where hypotheses are thrown and opinions questioning what was said are received. On a dais or on the ground, behind a table or not, sitting or standing, imagining stories and situations or showing verifiable facts, waiting for answers or raising reasonable doubts. Always being a performative act, of public exhibition of who’s doing it, leaving a learned part and an improvised part in the speech, while the vanity of that exhibition keeps creating adepts. About the conference, and about what’s hidden in doing it. And its link with the artistic.
