After post-truth, the age of post-reality ?

In a world where misinformation has eroded trust, a new frontier emerges: reality itself is contested. In his latest essay, « A l’assaut du réel » (PUF, 2025) Gérald Bronner explores this shift, tracing how unregulated desires and social dynamics shape our perception of the world. From technological amplification to ideological fervour, these forces destabilise what we once considered a shared reality.

In conversation with journalist and philosopher Simon Brunfaut, and through vivid examples of extraordinary communities, fascinating social worlds, and extensive data, Bronner will show how social dynamics, technology, and ideology distort perception and challenge our grasp of the real.

Are we still capable of preserving a common foundation of reality, or are we doomed to an era where everyone will forge their own world?

The discussion invites reflection on the future of our shared reality—and on what it means to live together when even facts feel uncertain.
