What was the Enlightenment? Are we now living through the end of the Enlightenment? To some, this seems to be precisely what is happening, especially when observing the rise of political populism, escalating religious violence, and the loss of trust in science and the media around us. The contemporary German philosopher Marie-Luise Frick guides us through the corridors of history and the various perceptions of enlightened thought, clarifying: the Enlightenment is not a cultural heritage whose content we always know beforehand; rather, at its core, it is the ability to think with courage and independence, which we must continue to do, constantly rediscovering it and ourselves along with it. Or, in Frick's words: "The future of humanity lies between despair and audacity."
