On June 18, 2024, we had the pleasure of welcoming guests from all around the world to celebrate the official inauguration of echo. After remarks were delivered by the president of Freie Universität Berlin, Prof. Dr. Günter M. Ziegler, the Berlin Senator for Science, Health and Care, Dr. Ina Czyborra as well as the Dean of the Department of Philosophy and Humanities, Prof. Dr. Jan Lazardzig, echo Director Anita Traninger held her inaugural lecture entitled "Chiming in. Echo, Parrhesia and the Media of Rhetoric" [Das Wort ergreifen. Echo, Parrhesia und die Medien der Rhetorik]“; the text can be found here. The official part of the event was duly concluded by a wonderful performance of Russian-American academic and poet Eugene Ostashevsky, who playfully riffed on the themes of echo and resonance, including in a sonnet written specifically for the occasion.
