L’autrice nous parle de ses rencontres avec les œuvres d’Antoine de Saint-Exupéry, Sony Labou Tansi, Mariama Bâ et Simone de Beauvoir.

« Femmes philosophes à découvrir » (3/5). Si la philosophe passe pour plus radicale que son mari, il est néanmoins difficile de déterminer qui, dans leurs œuvres, a écrit quoi, tant le couple imbriquait vie privée et travail intellectuel.

LES ENFANTS DE MAIGRET (1/6) - En 1992, l’Américaine Donna Leon, installée à Venise, imaginait un policier italien intègre, casanier et bon père de famille. Trente ans et trente enquêtes plus tard, son héros n’a pas pris une ride.

Le document budgétaire envoyé ce lundi aux parlementaires acte une hausse de près de 15 milliards d'euros des dépenses de l'Etat l'an prochain par rapport aux enveloppes votées pour 2022, plusieurs ministères étant particulièrement bien servis. Rien ne transparaît réellement en revanche sur les pistes d'économies.

Littérature romanesque ou philosophie, polar ou fantasy… Peu importe le genre, impossible d’imaginer de vraies vacances sans un livre de poche. Alors que la collection Folio fête son cinquantenaire et 10/18 ses 60 ans, retour sur l’histoire et l’actualité du format de lecture préféré des Français, avec une large sélection de titres à glisser dans sa valise.

Could the universe be an elaborate game constructed by bored aliens?

Elon Musk thinks you don’t exist. But it’s nothing personal: he thinks he doesn’t exist either. At least, not in the normal sense of existing. Instead we are just immaterial software constructs running on a gigantic alien computer simulation. Musk has stated that the odds are billions to one that we are actually living in “base reality”, ie the physical universe. At the end of last year, he responded to a tweet about the anniversary of the crude tennis video game Pong (1972) by writing: “49 years later, games are photo-realistic 3D worlds. What does that trend continuing imply about our reality?”

This idea is surprisingly popular among philosophers and even some scientists. Its modern version is based on a seminal 2003 paper, Are We Living in a Computer Simulation? by the Swedish philosopher Nick Bostrom. Assume, he says, that in the far future, civilisations hugely more technically advanced than ours will be interested in running “ancestor simulations” of the sentient beings in their distant galactic past. If so, there will one day be many more simulated minds than real minds. Therefore you should be very surprised if you are actually one of the few real minds in existence rather than one of the trillions of simulated minds.

This idea has a long history in philosophical scepticism (the idea that we can’t know anything for sure about the external world) and other traditions. The Chinese Taoist sage Zhuangzi wrote a celebrated fable about a man who couldn’t be sure whether he was a man dreaming of being a butterfly, or a butterfly dreaming of being a man. René Descartes imagined that he might be being manipulated by an “evil demon” (or “evil genius”) that controlled all the sensations he experienced, while the 20th-century American philosopher Hilary Putnam coined the term “brain in a vat” to describe a similar idea. But while Neo in the Wachowskis’ 1999 film The Matrix really is a brain (or rather a whole depilated body) in a vat, the simulation hypothesis says that you do not have a physical body anywhere. “You” are merely the result of mathematical calculations in some vast computer.

Robots can’t think or feel, despite what the researchers who build them want to believe.
