Philosopher Daniel Dennett useless at 82

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

(Full disclosure: This loss is private. Dennett was a buddy and colleague of my partner, Sean Carroll. Sean and I’ve many fond reminiscences of shared meals and stimulating conversations on an unlimited vary of subjects with Dan over time. He was a real authentic and will probably be tremendously missed.)

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

“He was a towering determine in philosophy and specifically 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 now have 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 along 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 plenty of different subjects.

Dennett’s many books, whereas dense, nonetheless bought very properly and have been vastly influential, and he was a distinguished speaker in nice demand. His 2003 TED discuss, “The Illusion of Consciousness,” garnered greater than 4 million views. While he gained explicit 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 main focus, merely a pure extension of his extra central philosopical considerations.

David Wallace, historian and thinker of science on 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, have been irreversibly remodeled by trendy 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 principle, for 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 on the cautious conceptual evaluation that characterizes the most effective philosophy, whereas caring deeply about what science has to show us concerning 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 might learn and who had an actual impression on the broader world. People like which can be extremely uncommon and valuable, and his passing is an actual loss.”

Born in Boston in 1942, Dennett’s father was a professor of Islamic historical past who turned a undercover agent for the OSS throughout World War II, posing as a cultural attaché on the American Embassy in Beirut. Dennett spent his early childhood there till his father was killed in a aircraft 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—not less than 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 turn out to be a thinker, initially intent on proving Quine fallacious. By the time he was a graduate pupil at Oxford University, he was identified 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 subject 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, slightly than a part of one’s personal physique. He questioned what was happening within the physique and the mind.

“The different philosophers thought, that’s not philosophy. I stated, properly, it needs to be,” he informed Tufts Now final 12 months. “So I began studying. I didn’t even know what a neuron was again then within the early ’60s, however I quickly discovered. I used to be fortunate to get in on the bottom flooring of cognitive neuroscience. Some of the early pioneers in that subject have been my heroes and mentors and pals.”

Dennett’s first tutorial place was on the University of California, Irvine, and a revised model of his doctoral thesis turned his first ebook: 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, creator of the bestselling Gödel, Escher, Bach: an Eternal Golden Braid, who known 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 stunning conclusions about consciousness (primarily that it’s simply an emergent impact of bodily interactions of tiny inanimate parts), and from then on, he was a dead-set opponent of dualism (the concept that there’s an ethereal nonphysical elixir known as “consciousness”, over and above the bodily occasions going down within the enormously complicated substrate of a human or animal mind, and maybe that of a silicon community as properly).  Dan thus completely rejected the notion of “qualia” (pure sensations of things like colours, tastes, and so forth), and his arguments towards the mystique of qualia have been refined however very cogent.

Dennett was a a confirmed compatibilist on the fiercely debated topic of free will, which 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 a freedom in it,” Hoftstadter recalled.

Johns Hopkins thinker Jenann Ismael recalled corresponding with Dennett after her personal ebook 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 ebook was largely vital of his stance on the topic. Ismael opened her ebook by discussing Dennett’s fictional quick story, “Where Am I?“, calling it “the most effective of piece of philosophical fiction ever written.” (Check out this quick movie based mostly on the story, starring Dennett himself uttering such immortal traces as, “They made a glowing new vat for my mind.”)

Dennett learn her ebook 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 concerning the plot of his quick story. “It seems I bought 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 ebook, he wasn’t as eager to right me as he was excited to speak concerning the concepts.”

She discovered him to be stuffed with infectious heat. “It was true that he might suck the air out of a room when he entered and even sitting at a spherical dinner desk, he someway turned the middle of it, he took possession of the dialogue,” stated Ismael. “But he additionally paid shut consideration to folks, learn voraciously, listened to and heard what others have been saying, taking what he might and disseminating what he discovered. He had immense curiosity and he wished to share the whole lot that he discovered or favored.”

In his later years, Dennett wasn’t shy about sounding the alarm concerning AI, even writing an article for The Atlantic final 12 months on the subject concerning the risks forward, notably with the appearance of massive language fashions like ChatGPT.  “The most urgent drawback isn’t that they’re going to take our jobs, not that they’re going to alter 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 may’t inform fact from falsehood. You don’t know who to belief. Trust seems to be one of the vital necessary 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 visitors in false modesty over his many accomplishments and at all times 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 liked artwork, music, crusing, pottery, trout fishing, windsurfing, ran his personal cider press, and made his personal Calvados on a Prohibition-era nonetheless. He might 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 bought the farm round 2014.)

“Dan was a bon vivant, a really zesty fellow, who liked journey and hobnobbing with brilliance wherever he might discover it,” Hoftstadter wrote in his tribute.  “In his later years, as he grew somewhat teetery, he proudly carried a wood cane with him all world wide, and into it he chiseled phrases and pictures that represented the numerous locations he visited and gave lectures at. Dan Dennett was a mensch, and his concepts on so many topics will go away a long-lasting impression on the world, and his human presence has had a profound impression on these of us who have been fortunate sufficient to know him properly and to depend him as a buddy.”

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