En Echoes ofel Círculo (Radio Circle) we dedicate the space to a new installment of the Dialogues for critical innovation, which took place on February 7, 2022, starring the professor of Classical Philology at the Autonomous University of Madrid Luis Unceta, and María Folguera, writer, playwright, and cultural manager. This dialogue explores the usefulness of the past in guiding us toward real and effective innovation; drawing on centuries-old (some millennia-old) texts and practices can help us identify precisely what we want to achieve with certain changes and why we want to undertake them.
