Thinker 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 at this time on the age of 82.

(Full disclosure: This loss is private. Dennett was a pal 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 shall be tremendously missed.)

Surprised reactions to Dennett’s surprising passing started proliferating on social media shortly after the information broke. “Wrenching information. He is been a fantastic pal and unimaginable inspiration for me all through my profession,” the Santa Fe Institute’s Melanie Mitchell, writer of Synthetic Intelligence: A Information for Pondering People, 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 have now 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 lots of different subjects.

Dennett’s many books, whereas dense, nonetheless offered very effectively and have been vastly influential, and he was a distinguished speaker in nice demand. His 2003 TED speak, “The Phantasm of Consciousness,” garnered greater than 4 million views. Whereas he gained explicit prominence as a frontrunner of the “New Atheist” motion of the early 2000s—colorfully dubbed one of many “4 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 on the College of Pittsburgh, provided 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 mentioned 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 reworked by fashionable science, most particularly by pure choice.

His method, 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, 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 educational philosophy.

“Dan Dennett was the embodiment of a pure thinker—somebody who was sensible on 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 College physicist and thinker Sean Carroll advised Ars. “On the similar time, he was the mannequin of a publicly-engaged educational, somebody who wrote substantive books that anybody might learn and who had an actual influence on the broader world. Folks 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 grew to become a undercover agent for the OSS throughout World Battle 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 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. However after graduating from the Phillips Exeter Academy, Dennett opted to attend Wesleyan College as a substitute—at the very least till be got here throughout Harvard logician and thinker W.V.O. Quine’s 1963 treatise, From a Logical Level of View.

Dennett ended up transferring to Harvard to review below Quine and change into a thinker, initially intent on proving Quine mistaken. By the point he was a graduate pupil at Oxford College, he was recognized amongst his fellow college students as “the village Quinean.” In his 2023 memoir, I’ve Been Pondering, 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, moderately than a part of one’s personal physique. He questioned what was happening within the physique and the mind.

“The opposite philosophers thought, that’s not philosophy. I mentioned, effectively, it must be,” he advised 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 ground of cognitive neuroscience. Among the early pioneers in that subject have been my heroes and mentors and mates.”

Dennett’s first educational place was on the College of California, Irvine, and a revised model of his doctoral thesis grew to become his first e book: 1969’s Content material and Consciousness. He moved to Tufts College in 1971, the place he remained for the remainder of his profession. One in all Dennett’s earliest collaborators was Douglas Hofstadter, writer of the bestselling Gödel, Escher, Bach: an Everlasting 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. Fairly 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 parts), and from then on, he was a dead-set opponent of dualism (the concept that there may be an ethereal nonphysical elixir known as “consciousness”, over and above the bodily occasions happening within the enormously advanced substrate of a human or animal mind, and maybe that of a silicon community as effectively).  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 e book on free will, How Physics Makes Us Free, was printed in 2016.  She had not but met Dennett, however his work was naturally a big affect, though her e book was largely essential of his stance on the topic. Ismael opened her e book by discussing Dennett’s fictional quick story, “The place Am I?”, calling it “one of the best of piece of philosophical fiction ever written.” (Try this quick movie primarily based 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 number 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 mistaken,” Ismael advised Ars.  “I might learn it so way back, I simply embellished it in my head and embarrassingly by no means realized. The place I criticized him in my e book, he wasn’t as eager to right 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 might 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,” mentioned Ismael. “However 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 all the things that he discovered or preferred.”

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 in regards to the risks forward, notably with the appearance of huge language fashions like ChatGPT.  “Essentially the most urgent downside just 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 advised Tufts Now. “They’re going to maneuver us right into a world the place you possibly can’t inform reality from falsehood. You don’t know who to belief. Belief seems to be one of the vital vital options of civilization, and we are actually at nice danger of destroying the hyperlinks of belief which have made civilization attainable.”

Dennett was not one to site visitors in false modesty over his many accomplishments and all the time evinced a powerful 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 tutorial. 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 Seventies. (He offered 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 various locations he visited and gave lectures at. Dan Dennett was a mensch, and his concepts on so many topics will depart a long-lasting influence on the world, and his human presence has had a profound influence on these of us who have been fortunate sufficient to know him effectively and to rely him as a pal.”

Ismael recalled him sending her YouTube movies of “swing dancing and foolish outfits” throughout the pandemic, his emails suffering from colourful emojis. He was “a wierd man, who did not take himself as critically as you may suppose,” she mentioned. “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 not possible he’s gone.”
