Daniel C. Dennett, one of the broadly learn and debated American philosophers, whose prolific works explored consciousness, free will, faith and evolutionary biology, died on Friday in Portland, Maine. He was 82.
His loss of life, at Maine Medical Middle, was attributable to issues of interstitial lung illness, his spouse, Susan Bell Dennett, mentioned. He lived in Cape Elizabeth, Maine.
Mr. Dennett mixed a variety of data with a straightforward, typically playful writing fashion to achieve a lay public, avoiding the impenetrable ideas and turgid prose of many different modern philosophers. Past his greater than 20 books and scores of essays, his writings even made their approach into the theater and onto the live performance stage.
However Mr. Dennett, who by no means shirked controversy, typically crossed swords with different famed students and thinkers.
An outspoken atheist, he at occasions appeared to denigrate faith. “There’s merely no well mannered solution to inform individuals they’ve devoted their lives to an phantasm,” he mentioned in a 2013 interview with The New York Occasions.
In line with Mr. Dennett, the human thoughts is not more than a mind working as a collection of algorithmic capabilities, akin to a pc. To consider in any other case is “profoundly naïve and anti-scientific,” he informed The Occasions.
For Mr. Dennett, random likelihood performed a better position in decision-making than did motives, passions, reasoning, character or values. Free will is a fantasy, however a obligatory one to achieve individuals’s acceptance of guidelines that govern society, he mentioned.
Mr. Dennett irked some scientists by asserting that pure choice alone decided evolution. He was particularly disdainful of the eminent paleontologist Stephen Jay Gould, whose concepts on different elements of evolution have been summarily dismissed by Mr. Dennett as “goulding.”
Not surprisingly, Mr. Dennett’s writings might elicit sturdy criticism as properly — to which he generally reacted with fury.
Daniel Clement Dennett III was born on March 28, 1942, in Boston, the son of Daniel Clement Dennett Jr. and Ruth Marjorie (Leck) Dennett. His sister, Charlotte Dennett, was a lawyer and journalist.
Mr. Dennett spent a part of his childhood in Beirut, Lebanon, the place his father was a covert intelligence agent posing as a cultural attaché in america Embassy, whereas his mom taught English on the American Neighborhood College.
He graduated from Harvard College in 1963 and two years later earned a Ph.D. in philosophy from Oxford College. His dissertation started a lifelong quest to make use of empirical analysis as the premise of a philosophy of the thoughts.
Mr. Dennett taught philosophy on the College of California, Irvine, from 1965 to 1971. He then spent virtually his total profession on the school of Tufts College, the place he was director of its Middle for Cognitive Research and most lately an emeritus professor.
His first ebook to draw widespread scholarly discover was “Brainstorms: Philosophical Essays on Thoughts and Psychology,” revealed in 1978.
In it, Mr. Dennett asserted that a number of choices resulted in an ethical selection and that these prior, random deliberations contributed extra to the way in which a person acted than did the last word ethical resolution itself. Or, as he defined:
“I’m confronted with an necessary resolution to make, and after a specific amount of deliberation, I say to myself: ‘That’s sufficient. I’ve thought of this matter sufficient and now I’m going to behave,’ within the full information that I might have thought of additional, within the full information that the eventualities might show that I made a decision in error, however with the acceptance of duty in any case.”
Some main libertarians criticized Mr. Dennett’s mannequin as undermining the idea of free will: If random choices decide final selection, they argued, then people aren’t liable for his or her actions.
Mr. Dennett responded that free will — like consciousness — was based mostly on the outdated notion that the thoughts needs to be thought of separate from the bodily mind. Nonetheless, he asserted, free will was a obligatory phantasm to take care of a steady, functioning society.
“We couldn’t reside the way in which we do with out it,” he wrote in his 2017 ebook, “From Micro organism to Bach and Again: The Evolution of Minds.” “If — as a result of free will is an phantasm — nobody is ever accountable for what they do, ought to we abolish yellow and purple playing cards in soccer, the penalty field in ice hockey and all the opposite penalty techniques in sports activities?”
Already with the 1991 publication of his ebook, “Consciousness Defined,” Mr. Dennett had expounded his perception that consciousness could possibly be defined solely by an understanding of the physiology of the mind, which he seen as a type of supercomputer.
“All sorts of notion — certainly all sorts of thought or psychological exercise — are completed within the mind by parallel, multitrack processes of interpretation and elaboration of sensory inputs,” he wrote. “Data coming into the nervous system is underneath steady ‘editorial revision.’”
By the Nineties, Mr. Dennett had more and more sought to clarify the event of the mind — and illusions of a separate consciousness and free will — by way of the evolution of human beings from different animal life.
He believed that pure choice was the overwhelming issue on this evolution. And he insisted that bodily and behavioral traits of organisms developed primarily via their helpful results on survival or replica, thus enhancing an organism’s health in its setting.
Critics, like Mr. Gould, cautioned that whereas pure choice was necessary, evolution would additionally must be defined by random genetic mutations that have been impartial and even considerably damaging to organisms, however that had develop into mounted in a inhabitants. In Mr. Gould’s view, evolution is marked by lengthy intervals of little or no change punctuated by brief, fast bursts of great change, whereas Mr. Dennett defended a extra gradualist view.
Underlying the more and more acrimonious debate between the students was a pure friction within the scientific and philosophical communities over which aspect merited extra credibility as regards to evolution.
Mr. Dennett additionally plunged into controversy together with his strident views on atheism. He and a colleague, Linda LaScola, researched and revealed a ebook in 2013, “Caught within the Pulpit: Leaving Perception Behind,” based mostly on interviews with clerics of assorted denominations who have been secret atheists. They defended their resolution to proceed preaching as a result of it supplied consolation and wanted ritual to their congregations.
Interviews with clergy from the ebook grew to become the premise of a play by Marin Gazzaniga, “The Unbelieving,” which was staged Off Broadway in 2022.
Eight years earlier, Mr. Dennett’s views on evolutionary biology and faith have been the topic of “Thoughts Out of Matter,” a 75-minute-long musical composition by Scott Johnson carried out in a seven-part live performance at a theater in Montclair, N.J. The composer used recordings from Mr. Dennett’s lectures and interviews.
Mr. Dennett’s fame and following prolonged to each side of the Atlantic. As he grew older, he was accompanied by his spouse on his lecture excursions overseas. Along with his spouse, his survivors embody a daughter, Andrea Dennett Wardwell; a son, Peter; two sisters, Cynthia Yee and Charlotte Dennett; and 6 grandchildren.
Whereas Mr. Dennett by no means held again in contradicting the views of different students, he bristled at harsh feedback about his personal work. This was particularly the case when Leon Wieseltier, a widely known author on politics, faith and tradition, strongly criticized Mr. Dennett’s 2006 finest vendor, “Breaking the Spell: Faith as a Pure Phenomenon,” in The New York Occasions Ebook Overview.
Contending that Mr. Dennett was illiberal of people that didn’t share his fundamental perception that science might clarify all human situations, Mr. Wieseltier concluded: “Dennett is the form of rationalist who provides cause a nasty title.”
In a prolonged, offended rebuttal, Mr. Dennett denounced Mr. Wieseltier for “flagrant falsehoods” that demonstrated a “visceral repugnance that pretty haunts Wieseltier’s railing (with out arguments) towards my arguments.”
An earlier, extra constructive appraisal of one other of his finest sellers, “Sorts of Minds: Towards an Understanding of Consciousness” (1996), that ran in New Scientist journal may need come closest to explaining Mr. Dennett’s enduring attraction.
Whereas he admitted that most of the questions he raises in his work “can not but be answered,” wrote the reviewer, Mr. Dennett “argues that placing the suitable questions is a vital step ahead.”
