Less Than Human: Taking on a Reviewer
I know that David wasn’t happy with Barbara Ehrenreich’s review. Here is Dave’s response – pasted in below as well.
To the Editors:
It is difficult for an author to respond to a review without sounding churlish, but at the same time, it is incumbent upon an author not to allow misrepresentations of his or her work to go unchallenged. It in is this spirit that I am moved to respond to Barbara Ehrenreich’s review of my book Less Than Human: Why We Demean, Enslave, and Exterminate Others.
My mission in Less Than Human was twofold. First, I sought to demonstrate the extraordinary pervasiveness of dehumanization across cultures and throughout history as an incentive to violence against whole populations — populations that are imagined to be less than human. And second, I offered a theory of dehumanization: an account of what it is about human nature that makes dehumanization possible. It is in attempting to engage with this theory that Ehrenreich drops the ball. She puzzlingly characterizes my theory as claiming that human cruelty to other humans “is based on a kind of cognitive error — a failure to recognize our conspecifics.” Errors are accidental, and therefore purposeless, disruptions of normal psychological processes. But I do not regard dehumanization as some sort of cognitive hiccup. Dehumanization has a function: the function of obliterating our awareness of the humanity of those upon whom we wish to visit harm. Ehrenreich goes on to assert in a similar vein that
Smith passes over the fact that wars have also been fought routinely and repeatedly among people who do recognize each other as fully human — whatever that may mean — people who, in times of peace, intermarry and trade with each other, and who may be as difficult for an outsider to distinguish as Irish Protestants and Catholics, Serbs and Croats.
But I do not propose that warring groups must dehumanize one another; only that they are often inclined to do so. Our readiness, in times of war, to dehumanize those formerly regarded as fellow humans is not a counterexample to my thesis: rather, it instantiates the phenomenon for which my theory is intended as an explanation.
When we dehumanize others, two psychological dispositions work in tandem: our continued adherence — often in spite of ourselves — to the hoary notion that the cosmos is an ordered moral hierarchy of beings, and our tendency to distinguish the essence of a thing from its appearance. We imagine that although certain others have a human appearance, they possess a sub-human essence. Although decked out in the superficial trappings of humanity, these beings are taken to really be dangerous predators, vermin, beasts of burden, or animals to be hunted for sport. The imaginative alchemy by means of which this transmutation is performed requires a mind that is endowed with considerable cognitive horsepower. Its perpetrator must be adept at juggling sophisticated concepts, such as essence and appearance, morally higher and morally lower. In other words, only creatures with minds like ours have what it takes to dehumanize — or, more broadly, “despeciate” — others.
Ehrenreich is unmoved by these considerations. Poking fun at my claim that the capacity to dehumanize others “is a testimony to our superior intelligence”, she goes on to assert that it has been empirically refuted. “There’s no point in belaboring the irony in Smith’s assertion that our apparent failure to consistently recognize conspecifics arises, not from thick-headedness, but from our presumed intellectual gifts,” she writes:
Would smarter chimpanzees be capable of “de-chimpizing” each other? The empirical roadblock Smith faces here is that chimps do in fact sometimes “de-chimpize” each other, or treat each other with what animal behaviorists have called “gratuitous cruelty,” as if the “enemy” chimp were a non-conspecific prey animal, such as a monkey. Smith wriggles out of this by warning against attributing “human-like mental states” to chimps.
Reading these words, one might come away with the impression that I have high-handedly ignored evidence gathered by primatologists. In fact, I discuss this in considerable detail, and give careful, critical attention to the very comment about “gratuitous cruelty” (made by Richard Wrangham and Dale Peterson in their bookDemonic Males: Apes and the Origins of Human Violence) to which Ehrenreich refers. Facts about chimpanzee behavior do not present an “empirical roadblock” precisely because dehumanization and related phenomena cannot be cashed out in purely behavioral terms. It is true that when chimpanzees attack their neighbors, they behave in much the same way as they do when hunting for red colobus monkeys, their favorite prey. Given that we cannot climb inside the chimpanzee mind and view the world from their perspective, we will never be certain that they do conceive of other chimps as merely monkeys in chimpanzee form: as unterchimpen. But this interpretation of their behavior is rendered implausible by what we know — or, at least, what we think we know — about the limits of chimpanzee cognition.
Of all the creatures on this earth, we alone, it seems, possess the intellectual prowess and imaginative reach to deceive ourselves in this manner. Tragically, the mental capacities that underpin our most wonderful cultural accomplishments also fuel our most terrible depredations. Understanding precisely how this works should, I believe, be considered as one of our most pressing priorities.

Can it really be twenty years since Dennett’s Consciousness Explained? There were of course many reviews of said book but check out Galen Strawson’s review.
Chalmers’ TED talk on The Extended Mind
The Extended Mind – I think that this is the first time Dave has expanded the idea to social extension or networks. I recall that FB post he mentions.
And Dave is trailing on his website his forthcoming book Constructing the World (OUP). BIG NEWS!!
Soul Dust, the Magic of Consciousness
The first of Nicholas Humphrey’s Pufendorf Lectures plugging his new book. Here is a recent review from the NYT.
David Stove
I know that I may well cop a lot of flack disclosing that I’m a fan of David Stove. One colleague called Stove the worst curmudgeon he’d ever come across, a writer that had the ability to rub many constituencies up the wrong way. Be that as it may, I find Stove a great writer and a worthwhile voice against the prevailing milieu in which he wrote – I like a “damn the torpedoes” attitude from time to time, Dennett being the best current practitioner. The reason I mention Stove is that I had the good fortune to meet Jim Franklin, Stove’s literary executor. I learned from Jim that a new and the last posthumous collection of Stove’s has just been published, edited by Andrew Irvine at UBC. Here is the Stove page maintained by Jim Franklin and an article by Roger Kimball (who has also written the forward to this latest work). For what it’s worth here is Stove’s Wikipedia entry. A good link is to Scott Campbell’s bio-sketch of Stove. For the more technically minded here is a reference to Stove’s The Problem of Induction.
Update: I now have a copy of the book courtesy of the editor Andrew Irvine. The title essay (the only essay) comprises some 100 pages. Another 100 or so pages is devoted to Stove’s bibliography. I see that Roger Scruton is featured on the dust-jacket blurb and that Andrew (rightly) takes on Hayek in his introduction. Kimball presents a very good portrait of Stove.
Res Cogitans Extensa: update
A few weeks ago I trailed the release of Georg Theiner’s Res Cogitans Extensa: A Philosophical Defense of the Extended Mind Thesis. Then there was no page devoted to Georg’s book by the publisher. Well now there is so check out the book’s page here. I have the book in hand – scanning it promises a good read. My only gripe is that there is no index. Hopefully, some close-grained reviews will appear over the course of the next year.
Hayek, Weimer, Gibson and Rosch
Here is the flyer from the legendary conference convened by Walt Weimer – the other notables included Gibson, who I’m told snubbed Hayek despite so warmly receiving The Sensory Order and Eleanor Rosch later to find fame as co-author of The embodied mind: Cognitive science and human experience. It is amazing that Weimer had (still has I might add!!) such balls and foresight to see Hayek’s genius – after all – Hayek was a rank outsider. Doff of hat and raised glass to Walt Weimer! Weimer was, by the way, interviewed by Bernard Baars some years ago but there was no mention of Hayek. Many thanks to Jim Wible, a student of Walt Weimer, who so kindly dug out this flyer out. Also thanks to Walt’s other students (Bill Butos, Harry Heft, Denny Proffitt and John Johnson) who came forward with such vivid memories of this amazing character – here are some photos from that conference. Last, but by no means least, it was my late chum Rob Haskell who, when I innocently asked if he knew Weimer, got very animated (this was in mid-winter at a nondescript bar in the Maine Mall). He had much he wanted to chat about at some later date – it wasn’t to be.
Stigmergic Bridge
Coherence with concept and algorithm
A network bridge which connects multiple points on ground and a subway station. The circulation, structure and enclosure are based on stigmergy algorithm operated on three different scales.
Arguments based on stigmergy
Articulation of materialization is achieved by orienting components to structure and enclosure “pheromone”. The components gradually change size and color from structure to enclosure, forming a solid entity.

A few months ago I came across the work of architectural student Yang Chenghan. It’s amazing that I have not come across any other architects deploying stigmergic algorithms – one would think that the concept would be part and part of an architect’s conceptual toolbox. Good for Yang – I’d imagine this guy has a bright career ahead of him. Here are some new images of what he terms a stigmergic bridge.
