Philosopher Daniel Dennett dead at 82

World famend thinker Daniel Dennett, who championed controversial takes on consciousness and free will amongst different mind-bending topics, died immediately at the age of 82.

(Full disclosure: This loss is private. Dennett was a good friend and colleague of my partner, Sean Carroll. Sean and I’ve many fond reminiscences of shared meals and stimulating conversations on an infinite vary of subjects with Dan through the years. He was a real unique and might be significantly missed.)

Stunned reactions to Dennett’s surprising passing started proliferating on social media shortly after the information broke. “Wrenching information. He’s been an ideal good friend and unbelievable inspiration for me all through my profession,” the Santa Fe Institute’s Melanie Mitchell, writer of Artificial Intelligence: A Guide for Thinking Humans, wrote on X. “I’ll miss him enormously.”

“He was a towering determine in philosophy and particularly within the philosophy of AI,” roboticist Rodney Brooks (MIT, emeritus) wrote on X, bemoaning that he’d by no means replied to Dennett’s final e mail from 30 days in the past. “Now we’ve solely reminiscences of him.

A 2017 New Yorker profile described Dennett as “a cross between Darwin and Santa Claus,” with “a fluffy white beard and a spherical stomach.” That jolly look was accompanied by an mental ferocity—generously embellished together with his glowing wit—as he battled such luminaries as Stephen J. Gould, John Searle, Noam Chomsky, David Chalmers, Roger Penrose, and Richard Lewontin, amongst others, over consciousness and evolution, free will, AI, faith, and lots of different subjects.

Dennett’s many books, whereas dense, nonetheless offered very nicely and had been massively influential, and he was a distinguished speaker in nice demand. His 2003 TED speak, “The Illusion of Consciousness,” garnered greater than 4 million views. While he gained specific prominence as a pacesetter of the “New Atheist” motion of the early 2000s—colorfully dubbed one of many “Four Horsemen of New Atheism” alongside Richard Dawkins, Christopher Hitchens, and Sam Harris—that was by no means his major focus, merely a pure extension of his extra central philosopical issues.

David Wallace, historian and thinker of science at the University of Pittsburgh, supplied Ars Technica this succinct summation of Dennett’s extraordinary affect:

To me, Dan Dennett exemplified what it means to do philosophy in an age of science. He as soon as stated that there was no such factor as philosophy-free science, solely science that didn’t interrogate its philosophical assumptions; equally, he noticed extra deeply than virtually anybody that the deepest conventional questions of philosophy, from free will to consciousness to metaphysics, had been irreversibly remodeled by fashionable science, most particularly by pure choice.

His strategy, as a lot as his personal towering contributions, has impressed generations of philosophers, far past cognitive science and the philosophy of thoughts (his concepts have been influential within the interpretation of quantum idea, as an example). He was one of many nice philosophers of the final century, and one of many only a few whose work has been transformative outdoors tutorial philosophy.

“Dan Dennett was the embodiment of a pure thinker—somebody who was sensible at the cautious conceptual evaluation that characterizes one of the best philosophy, whereas caring deeply about what science has to show us in regards to the pure world,” Johns Hopkins University physicist and thinker Sean Carroll informed Ars. “At the identical time, he was the mannequin of a publicly-engaged tutorial, somebody who wrote substantive books that anybody may learn and who had an actual affect on the broader world. People like which might be extremely uncommon and treasured, and his passing is an actual loss.”

Born in Boston in 1942, Dennett’s father was a professor of Islamic historical past who grew to become a undercover agent for the OSS throughout World War II, posing as a cultural attaché at the American Embassy in Beirut. Dennett spent his early childhood there till his father was killed in a airplane crash whereas on a mission to Ethiopia. Dennett, his mom, and two sisters returned to Boston after that, and his household assumed he would attend Harvard similar to his late father. But after graduating from the Phillips Exeter Academy, Dennett opted to attend Wesleyan University as a substitute—at least till be got here throughout Harvard logician and thinker W.V.O. Quine’s 1963 treatise, From a Logical Point of View.

Dennett ended up transferring to Harvard to review below Quine and develop into a thinker, initially intent on proving Quine fallacious. By the time he was a graduate pupil at Oxford University, he was recognized amongst his fellow college students as “the village Quinean.” In his 2023 memoir, I’ve Been Thinking, Dennett traced his curiosity in making use of his discipline to questions of science started throughout this era. He recalled experiencing the common sensation of 1’s hand falling asleep and feeling like an alien factor, fairly than a part of one’s personal physique. He questioned what was occurring within the physique and the mind.

“The different philosophers thought, that’s not philosophy. I stated, nicely, it must be,” he informed Tufts Now final yr. “So I began studying. I didn’t even know what a neuron was again then within the early ’60s, however I quickly realized. I used to be fortunate to get in on the bottom ground of cognitive neuroscience. Some of the early pioneers in that discipline had been my heroes and mentors and pals.”

Dennett’s first tutorial place was at the University of California, Irvine, and a revised model of his doctoral thesis grew to become his first e-book: 1969’s Content and Consciousness. He moved to Tufts University in 1971, the place he remained for the remainder of his profession. One of Dennett’s earliest collaborators was Douglas Hofstadter, writer of the bestselling Gödel, Escher, Bach: an Eternal Golden Braid, who referred to as Dennett “a lodestar in my life” in an e mail [quoted with permission] to colleagues after listening to of the latter’s demise:

Dan was a deep thinker about what it’s to be human. Quite early on, he arrived at what many would see as surprising conclusions about consciousness (primarily that it’s simply an emergent impact of bodily interactions of tiny inanimate elements), and from then on, he was a dead-set opponent of dualism (the concept that there’s an ethereal nonphysical elixir referred to as “consciousness”, over and above the bodily occasions going down within the enormously advanced substrate of a human or animal mind, and maybe that of a silicon community as nicely).  Dan thus completely rejected the notion of “qualia” (pure sensations of things like colours, tastes, and so forth), and his arguments in opposition to the mystique of qualia had been delicate however very cogent.

Dennett was a a confirmed compatibilist on the fiercely debated topic of free will, that means that he noticed no battle between philosophical determinism and free will. “Our solely notable divergence was on the query of free will, which Dan maintained exists, in some sense of ‘free,’ whereas I simply agreed that ‘will’ exists, however maintained that there isn’t any freedom in it,” Hoftstadter recalled.

Johns Hopkins thinker Jenann Ismael recalled corresponding with Dennett after her personal e-book on free will, How Physics Makes Us Free, was revealed in 2016.  She had not but met Dennett, however his work was naturally a big affect, despite the fact that her e-book was largely essential of his stance on the topic. Ismael opened her e-book by discussing Dennett’s fictional quick story, “Where Am I?”, calling it “one of the best of piece of philosophical fiction ever written.” (Check out this quick movie based mostly on the story, starring Dennett himself uttering such immortal strains as, “They made a glowing new vat for my mind.”)

Dennett learn her e-book and emailed Ismael with a couple of notes—not about how he felt she’d misrepresented his views (which he deemed of “regardless of”) however correcting her errors in regards to the plot of his quick story. “It seems I received the story fallacious,” Ismael informed Ars.  “I’d learn it so way back, I simply embellished it in my head and embarrassingly by no means realized. Where I criticized him in my e-book, he wasn’t as eager to appropriate me as he was excited to speak in regards to the concepts.”

She discovered him to be crammed with infectious heat. “It was true that he may suck the air out of a room when he entered and even sitting at a spherical dinner desk, he in some way grew to become the middle of it, he took possession of the dialogue,” stated Ismael. “But he additionally paid shut consideration to individuals, learn voraciously, listened to and heard what others had been saying, taking what he may and disseminating what he realized. He had immense curiosity and he wished to share every part that he realized or appreciated.”

In his later years, Dennett wasn’t shy about sounding the alarm concerning AI, even writing an article for The Atlantic final yr on the subject in regards to the risks forward, significantly with the arrival of enormous language fashions like ChatGPT.  “The most urgent downside isn’t that they’re going to take our jobs, not that they’re going to vary warfare, however that they’re going to destroy human belief,” he informed Tufts Now. “They’re going to maneuver us right into a world the place you possibly can’t inform fact from falsehood. You don’t know who to belief. Trust seems to be one of the vital essential options of civilization, and we at the moment are at nice threat of destroying the hyperlinks of belief which have made civilization potential.”

Dennett was not one to site visitors in false modesty over his many accomplishments and all the time evinced a robust diploma of self-confidence, fondly recounting in his memoir of the time fellow thinker Don Ross wryly noticed, “Dan believes modesty is a advantage to be reserved for particular events.”

His myriad pursuits weren’t restricted to the educational. Dennett cherished artwork, music, crusing, pottery, trout fishing, windsurfing, ran his personal cider press, and made his personal Calvados on a Prohibition-era nonetheless. He may name a sq. dance, whittle a wood strolling stick, and was keen on pondering knotty philosophical questions whereas driving his tractor on his 200-acre farm in Blue Hill, north of Boston, which he purchased within the Nineteen Seventies. (He offered the farm round 2014.)

“Dan was a bon vivant, a really zesty fellow, who cherished journey and hobnobbing with brilliance wherever he may discover it,” Hoftstadter wrote in his tribute.  “In his later years, as he grew just a little teetery, he proudly carried a wood cane with him all world wide, and into it he chiseled phrases and pictures that represented the various locations he visited and gave lectures at. Dan Dennett was a mensch, and his concepts on so many topics will go away an enduring affect on the world, and his human presence has had a profound affect on these of us who had been fortunate sufficient to know him nicely and to rely him as a good friend.”

Ismael recalled him sending her YouTube movies of “swing dancing and foolish outfits” throughout the pandemic, his emails affected by colourful emojis. He was “a wierd man, who did not take himself as significantly as you may suppose,” she stated. “I actually cherished him, cherished his spirit, his generosity, the expansiveness of his considering, his enjoyment of concepts, and his nice good cheer. Philosophically, I believe he had true greatness. It appears unattainable he’s gone.”
