Why do caterpillars hang from trees? They bungee jump from a silk thread in order to flee a hungry bird or other threat. They can crawl back up the thread or descend to the ground. How do beavers build their dams and lodges? With great variety and flexibility, never the same way twice, depending on the weather, landscape, population, and other factors. Animal Architects discusses insect silk, beaver dams, birds nests, bee hives, and other examples of animal building. The stories are fascinating in themselves, and the thesis is tells a larger story. The authors use numerous examples, from stereotyped wasp nests, to the highly flexible building strategies of beavers, to build taxonomies of mapping, from stimulus-response to concept-building, and social intelligence, from isolation to multi-dimensional decision-making. The picture of animal intelligence is much richer and more nuanced than the “stimulus-response” behaviorist school.
There is a strong perceived dichotomy between “intelligence” and “instinct”. It can be seen in today’s article Washington Post article about a recent scientific study showing that humans pleasure centers are stimulated by acts of generosity and kindness. The article quotes neuroscientists and philosophers suggesting that these scientific studies take moral judgements outside of the realm of morality and into the domain of physical determinism. “Joshua D. Greene, a Harvard neuroscientist and philosopher, said multiple experiments suggest that morality arises from basic brain activities. Morality, he said, is not a brain function elevated above our baser impulses. Greene said it is not “handed down” by philosophers and clergy, but “handed up,” an outgrowth of the brain’s basic propensities.” But the expression of morality – like other aspects of human behavior — intertwines instincts, emotions, culture, and reason. The interesting thing isn’t nature or nurture, it’s the fascinating combinations.

Leviathan and the Air-Pump
How did experimentation become accepted as a primary way of doing science? Leviathan and the Airpump,the history of science classic by Stephen Shapin and Simon Schaffer, looks at the historical transition in Restoration England, when the culture of experiment was just being invented. The book chronicles the dispute between Robert Boyle of the Royal Society, pioneers of experimental science, and Thomas Hobbes, whose work in political philosophy has been remembered, and whose work on mechanical philosophy, short on experiment and long on reasoned “proof”, has been largely forgotten.
It is an interesting question. Why, with the ability to demonstrate whether a scientific statement can be supported by facts, would someone choose to avoid experiment? Hobbes argues a few key points. Facts in the real world are messy. Boyle’s pump leaked, no two pumps were alike to permit replication; and there were other problems that led the results of experiments to be much more ambiguous than they appear in textbooks. Most important, Hobbes objected to the lack of causal logic. In geometry, Hobbes’ canonical form of natural philosophy, reasoned statements proceed methodically from axioms to incontrovertable conclusions. In purely empirical science, relationships between observation and conclusion are more ambiguous.
By contrasting Hobbes and Boyle, I wonder whether the authors stack the deck to maximise the contrast. Even within his peer group of experimentalists, Boyle was notoriously reticent to theorize. There are other pioneering experimentalists (Galileo, Huygens) who did more math; and whose process interleaved experimentation and mathematical theory. It seems as though Hobbes might have fewer problems with, say, Huygens’ work on pendulums.
The insight I found most interesting is the way the book shows how arguments in defense of alternative scientific methods were not only about how to prove knowledge, but about how to organize society. Both sides were anxious about maintaining civil order in the aftermath of the English civil war, and promoted their respective methods as processes for reaching agreement peaceably. Hobbes’ focused on creating geometric-style proofs that are so airtight that dispute is impossible. Boyle focused on removing philosophic discourse from the contentious topics of politics and religion, and allowing free argument on agreed facts.
One frustrating aspect of the book arises from its methodological refusal to be ahistorical. Responding to the tradition, in the history of science, of reading history from the perspective of known winners, and solved problems, the authors take the opposite approach, and try to present the world of 17th century natural philosophy without any more information than contemporaries had; the reader is left with the same puzzlement about “anomalous suspension”, cohering disks of marble, and other puzzles that did not get solved in the time frame under consideration. What’s more, the authors are deliberately anti-concerned with the scientific outcome.
I understand why the authors chose not to step out of the frame of 17th century knowledge and understanding; but I’d understand the content better with some additional glosses and appendices about the conclusions of later scientific work. Apparently, this book, Robert Boyle’s Experiments in Pneumatics. written in the 50s by James Conant, actually explains the science, and used copies are on the market.
The book belongs to school in the history of science that focuses on the sociology of science. I’ve heard three Bruno Latour references in the last week and need to pick up the thread there. The extreme side of the argument claims that there is nothing but sociology; but that takes us to Bush political appointees censoring global warming and forbidding the national park service to estimate the age of the Grand Canyon. It is useful to bracket science in order to understand its social context, but dangerous to assert that all knowledge is opinion and belief.
The Root of the Wild Madder
AP Correspondent Brian Murphy fell in love with Persian carpets, and followed the trail of carpets from present-day Iran and Afghanistan back through pre-historic times, in The Root of Wild Madder. The book tells a more human and nuanced story of those parts of the world than one gets by reading the political news these days.
A People’s History of Science
A People’s History of Science assembles lots of juicy anecdotes about the untold contributions of ordinary people to science and technology. Non-european navigators taught geography to Europen explorers — often as kidnapped hostages. Rice production in North Carolina was derived from the techniques of African slaves who were transported for their knowledge of rice culture. The canonical achievements of the scientific revolutions’s great chemists and astronomers included the contributions of un-named artisans and instrument-makers: Boyle and Brahe were as much managers and administrators as they were researchers; while the members of their labs are barely known. Major achievements in mechanical and chemical engineering had contributions from informally educated miners and brewers, Innovators including Leeuwehoek, John Harrison who invented the clock that enabled measurement of longitude, and William Smith who mapped the strata of the geological history needed to fight for credit because of their non-aristocratic social origin.
The author’s ideological point of view enables him to tell a history that would otherwise be invisible. The belief that much human knowlege has derived from the activities of working people, and that the bias of elites has obscured these contributions, enables him to assemble and organize these disparate stories into a collection. Creating a supported narrative fosters further questioning of conventional wisdom about the origins of science.
In other ways, though, Connor’s story obscures some other interesting historical questions. Conner tells the stories of Bernardin de Saint-Pierre, a naturalist at the time of the French Revolution whose writing about nature focused on ecological interrelationships, including phenomena such as mimicry and symbiosis. These ideas were not incorporated into biology until centuries later. Bernardin also believed in an extreme teleologism. For example, volcanoes are designed to purify the world’s water, while earthquakes are intended to purify the atmosphere. He was briefly prominent during the revolutionary period, and was excluded from the scientific establishment afterwards, for reasons combining politics and science. The interesting question is about the relationship between the validated and non-validated beliefs of early scientific figures. Isaac Newton’s practice included validated physics and invalidated alchemy; while Bernardin’s practice included validated ecosystem concepts and invalidated teleology. What is a good way to teach about these historical figures who investigated the unknowns of their time, and were sometimes right and sometimes wrong?
Similarly, Conner writes about Mesmer, the proponent of theories of “animal magnetism”, whose ideas were popularized by Nicolas Bergasse, an influential figure in the French Revolution who advocated against the dominance of the Academy. Bergasse led a social and political movement, combining healing through animal magnetism with radical social activism. The Academy thoroughly rejected “animal magnetism” as science. Conner argues that prejudice against the political views of the Mesmerists kept the academicians from uncovering the mind-body insights revealed by the hypnotic trances and spontaneous remissions experienced by the mesmerized. Conner asks a lot of the empirically minded, to patiently seek the evidence of mind-body interconnection amidst obvious evidence of charlatanism and quackery mixed with revolutionary politics. It seems easier for contemporary scientists to learn from the calm and non-evangelical masters of Tibetan Buddhism than it would have been for the committee including Ben Franklin and Antoine Lavoisier to learn from the proponents of mesmerism.
Conner’s interpretation of the scientific revolution, my favorite chapter in the book, draws from the work of Edgar Zilsel, a Marxist historian of science who fled Nazi Germany in 1938, and committed suicide in 1944. His work went into disrepute in the McCarthy era, and he wasn’t alive to complete and defend his work. Citing Zilsel, Conner shows how canonical scientific works like Gilbert’s De Magnete drew directly from the knowledge of “blacksmiths, miners, sailors and instrument makers”. Conner cites a variety of historians to argue that the high science of thermodynamics learned more from the practical inventors perfecting the steam engine than vice versa. This argument inverts conventional wisdom about the trajectory from pure research to applied, practical innovation. The “chicken and egg” arguments about scientific theory and technology reveal systematic biases driven by economic and social prejudice, and shows how the absurdities of the European caste system retarded the development of socience. But these arguments also obscure interesting questions about the interrelationships between engineering and science.
Elizabeth Eisenstein’s great work, The Printing Press as an Agent of Change, documents the influence of printing on the transmission of scientific and technical knowledge. Practical manuals for artisans were popular applications of early printing. The availability of technical documentation helped break down the power of guild secrecy and increase the pace of innovation. Evidently, reading and writing must have spread among artisans in order to transmit this technical knowledge.
Conner quotes Robert Boyle and other aristocratic figures who overcame their revulsion and reluctance to actually talk with vulgar tradesman. But the contrast between the Latin-learned aristocrats and uncultured brewers and bakers, barber-surgeons and traders is probably too stark, given the spread of vernacular technical literature in the sixteenth and seventeenth centuries. The interesting topic — perhaps covered by other history — is the interrelationship between scientific theory and engineering practice in the 18th and 19th centuries. Solid studies on this topic would require not only a social filter to recapture the economic and social relationships, but understanding of the engineering and science itself. Looks like the book that investigates this topic is Science and Technology in World History.
In summary, I liked the book because of the way it gathers stories that are not told often enough. The ideology that prompts the storytelling helps to get the story told, but also obscures other parts of the story.
Affective Computing doesn’t feel right
Currently reading Affective Computing by Rosalind Picard of MIT. The book envisions computers that are trained to detect and express emotions, and thereby become better servants of people. I think the premise is badly misguided, but interestingly so.
One core flaw is that I don’t think you can have the features of emotions without the bugs. Emotions are integral to the pleasure and pain-seeking circuits of an organism. When well-tuned, they help the organism survive and thrive. When off-balance, you get addiction and depression.
The author envisions affective computing as a personal technology. But this doesn’t map to way emotions are build into the social nature of the human species. The circuits used for love and loyalty also run betrayal and tribal hatred. Given the frequency of divorce and war, it seems unlikely that we’d be able to do a better job invoking social emotions in machines.
Crashing the Gate
My favorite thing about Crashing the Gate, the book by two leading liberal bloggers, is its indictment of the Democratic political consultant class. They make their money from percentage of political advertising, whether or not they win, which is quite a racket. They have a stranglehold on the dispensation of Democratic campaign funds. According to the book, they are the main proponents of the strategyof blandness: voters will vote for Democratic politicians if we don’t understand what they say; and of pandering to swing voters with non-issues like flag-burning.
Critics say the story isn’t new; but Markos Moulitsas and Jerome Armstrong get the story out to a broader audience than the policy wonks who have known this all along.
What I didn’t like as much about the book was how Kos and Jerome talk about online organizing. Mostly, they talk about how the internet is a new source of funding — and imply that they can be the next generation of political consultants who will gatekeep the collection and use of campaign funds. They give some lip service to online organizing and activism. But they don’t tell the interesting stories about how the internet can help assemble core groups, extend the reach of online organizing to the physical world, and use online education to put pressure on candidates and lawmakers.
What I liked least was the book’s indictment of liberal special interest groups. Kos and Armstrong encourage groups to drop their interests in the environment, women’s rights, and other issues, and to instead work on together to elect liberal candidates. I agree with the authors that bipartisan tactics are sometimes short-sighted — for example, womens’ groups support for individually pro-choice republicans is risky against the big picture of the republican party’s anti-abortion strategy.
Also, the focus on building an alliance of traditional liberal groups misses opportunities to be more aggressive and build a different majority. For example: Kos and Armstrong would rather environmentalists to take a lower profile, and subsume their call against global warming for a larger progressive agenda (whatever that is). Instead, environmentalists ought to cast a larger shadow, connecting the cause to economic growth; to business interests investing in bringing clean energy mainstream; to the national security benefit of energy independence; to religious people who believe in eath stewardship. This isn’t at all about “compromise”, it’s about building a larger majority by being assertive about core principles, and reaching out to those who might belive same things for different reasons.
I think that Kos and Armstrong’s electoral focus blinds them to the more complicated relationship between issue activism and campaigning. The activities during legislative sessions and campaigns are related but different. You do issue activism when the legislature is in session and you want the politicians to listen to you on a speciific topic. And then you do electoral campaigns favoring your broader goals.
Overall, I enjoyed the book and recommend it. It provides a powerful indictment of the structures that make democrats lose; and offers a bunch of good ideas for how Democrats could do better.
Coast of Dreams
Coast of Dreams, a survey of California history since 1990 is full of nuggets that explain the origins of Californian artifacts.
Where did the massive demonstrations in LA against the immigration bill come from? The tactics, from flagwaving, to the student walkouts, to the massive gatherings and the slogans, are repeats of the tactics used to protest proposition 187, the 1994 law that took health care and education services from undocumented immigrants, and was later ruled unconstitutional.
Where did Trader Joe’s come from? The founder’s original target market was Pasadena PhD students who had sophisticated tastes in food and poverty-level budgets.
What’s the economic base of San Diego? It used to be defense contracting, and now is more biotech and telecom.
Why does Silicon Valley have a string of surprisingly lively main streets in its string of suburban towns? It’s actually not uncommon in California, where new urbanist ideas have revived walkable town centers all over the state.
What happened after the LA riots in 1992? High profile redevelopment efforts by Peter Ueberroth and representatives of the oligarchy flopped. Economic revitalization came from an unexpected direction; toy and textile businesses, founded by immigrants who colonized the underutilized downtown buildings.
Why are there green hills in Marin? Because land conservancies have been buying up open space when there would otherwise be expensive housing.
Coast of Dreams tells the history of things that seem too unnatural to have a history; one interesting chapter compares and contrasts the beach culture of Santa Barbara with the golf culture of Palm Springs.
Is it a good book?
If you’ve been following California news closely for the last 15 years, Coast of Dreams might come across as a non-book. It is a collection of stories that one might assemble from reading the paper and watching how the stories develop over the years. The footnotes section is full of citations from the LA Times, the San Francisco Chronicle and the Sacramento Bee.
The book does have a loose theme. The economic hard times prompted by the end of the cold war, which caused some skeptics to forecast the end of the California Dream, was followed by a revival led by immigrant business, entertainment and tech. The book has nothing vaguely near the the depth of Common Ground the brilliant J. Anthony Lukas 1986 social history of the Boston busing crisis, which traced the history of the ethnic groups and social institutions in Boston through to their painful collisions in the 70s.
As a newcomer to California, I found Cost of Dreams fascinating. The author, Kevin Starr, was the state librarian and author of a series on California history, and the book contains a smattering of everything Californian, ranging from religion, to real estate development, to surfing history.
The best part of the book is the author’s sprawling knowledge of California visual art, literature, food and sports. The book contains thumbnail portraits of artist Richard Diebenkorn, landscape architect Nancy Goslee Power, novelist James Ellroy, and many other cultural figures. There’s a little gem of a section that wonders why LA’s novelists are so noir, while its poets and architects are cheerful.
Starr has a cheerful, culturally omnivorous esthetic that seems like an LA sensibility that’s different from the glossy cynicism of movie execs and plastic surgery ads. It would be really fun if the book were hypertext, with links to the people, places and pictures, and maybe an annotated google map.
Sometimes Starr’s cultural history is overinterpreted; for example, the growth of mexican-american art festivals is seen as a sign of racial detente in Los Angeles, which is surely a good thing, but not the same as a reduction in violence among Blacks, Latinos and Koreans.
This isn’t the book for a profound examination of causes. Starr writes about the disasters of fire and landslides that affect Southern California; The Control of Nature by John McPhee explains how patterns of fire suppression and building make the pattern inevitable.
Starr documents the brutal costs of the drug war in urban central Los Angeles and the rural Central Valley; but he doesn’t pause to consider alternatives. He refers to the growing economic inequality, but nothing about its causes.
Starr writes about the transformation in American food habits instigated by Alice Waters in Berkeley; Ruth Reichl’s memoir, Tender at the Bone tells the juicy details.
In summary, Coast of Dreams is an enjoyable introduction to contemporary California, but it’s far from the last word.
Unpacking the bookshelf: after mass marketing
When the internet was becoming commercial, I researched and wrote a multi-client study for the paper industry on the future of paper. In order to understand the consumer economy that drove the advertising support for newspapers and magazines, I researched the history of mass advertising, mass marketing and consumer culture to understand the old system that seemed on the verge of splintering.
Since then, the market for physical goods hasn’t changed as much as the dotcom era promised. But the market for text, music, video and software is changing rapidly. The web20ish cascade of user-generated content is as dramatic and more fun than one might have imagined, despite the bad laws that incumbent industries are trying to use to hold back time.
The scary collapse of the newspaper ad market is happening as predicted, along with a very scary decline of democracy.
I didn’t think that electronic displays would be cheap enough for books until around now. That market still hasn’t gone anywhere. The relationship between pixels and paper has gotten very strange, with books being used by bloggers, mostly as excuses for book tours.
Unpacking the bookshelf on environment and industrial ecology
And worrying that global warming might be too far along to reverse. Long before Jared Diamond’s Collapse, I read A Green History of the World: Environment and the Collapse of Civilizations. It talks about how human-catalyzed soil degradation led to the progressive decline of the Sumerian, Assyrian and Babylonian civilizations.
Phantoms in the Brain
What I liked about Phantoms in the Brain. The science. Neurologist VS Ramachandran investigates strange conditions including the phantom limbs of amputees, the delusional competencies of paralyzed stroke victims, and the religious epiphanies of epileptics. These oddities yield revelations about the workings of the brain and mind.
The sensations of phantom limbs, it turns out, are generated when the brain’s perceptual circuitry for a missing limb is colonized by brain cells intended for another body part. By understanding the mechanism of phantom sensation, Ramachandran figured out clever ways of retraining the brain to eliminate pain or accept the absense of the limb.
What I didn’t like: the last section of the book, a philosophical analysis of the attributes of consciousness. The connection to experimental science is much weaker in this section. It seemed as though there could be any number of ways to segment consciousness into N logical components, and these segmentations would be equivalently untestable.
What I appreciated: the book discussed the religious epiphanies experienced by some people with epilepsy. But it refrained from drawing conclusions about the validity of these experiences. It is welcome to see a scientist refrain from ascientific conclusions for or against religious belief. But Ramachandran commits a different and related solecism elsewhere in the book.
What I liked least: Quoting Indian scripture, Ramachandran uses the various bugs and gaps in the neurological system to argue that the experience of self and consciousness is an illusion. This argument is fallacious. Take as an analogy a software system that composed of multiple subsystems, each of which needs to work properly for the software to run. There may be some anomalies that occur with strange and unexpected input. But these facts do not somehow prove that the software does not work as intended under normal conditions. Similarly, the vision system is built from multiple components, and it is possible to fake out the system with optical illusions, but these facts don’t mean that vision is an illusion. The author is welcome to his beliefs, but they are not supported by his science.
