Guns, Germs, and Steel (book)

     Jared Diamond Guns, Germs, and Steel (1999) Diamond’s thesis is simple: in the long run, over several thousand years, what determined the dominance of Eurasia in human history was its early development of food production, and this in turn was governed by climate, ecology, and geography. These interacted. The ecology provided a large suite of plants and animals for domestication, and the geography gave Eurasia a wide band of similar climates within which to diffuse the new technology. By contrast, Africa and the Americas had a much smaller suite of plants and no large mammals suitable for domestication, while Australia had essentially none. Africa and the American continents also had climatic and geographic barriers to north-south diffusion of food production when it was developed.
     The thesis is persuasive, and Diamond’s point that long-term trends in history cannot have been influenced very much by culture or idiosyncratic accidents such as the rise of some anomalous individuals. He is also acutely aware of short term culturally determined twists in history. For example, the adoption of new technologies is influenced by a culture’s openness; but a culture that doesn’t quickly adopt new techniques will be overwhelmed (conquered, out-competed) by cultures that do. But individual decisions by rulers over large coherent cultures can have long-term consequences: China’s long decline in technology was caused by internal power struggles, and that’s why Western Eurasia dominates today rather than China. And so on.
     What might be called the E-C-G theory of history sounds like a theory that explains everything, but not quite. Diamond claims that it is a statistical theory: it can explain, and to some extent predict, large scale phenomena, but not small scale ones. In this respect human history is like all historical sciences, and Diamond insists that human history can be brought to a more objectively scientific state by learning from the  the methodologies of the other, simpler, historical sciences. These sciences are even capable of a kind of prediction: If theory X is true, then certain should be found in the historical record. In his defence of historical sciences Diamond doesn’t quite say what I want to say: Physics has been so spectacularly successful because it’s simple.
     A rich and suggestive book, made better by Diamond’s ability, unusual in an American academic, to write clearly. **** (2000)

The Hollow (book)

Agatha Christie The Hollow (1946) Late period Christie. John Christow, Harley street doctor and medical researcher, is murdered, and everything at first points towards Gerda his wife; then all clues point away, but  lead nowhere. Poirot eventually realises that this is the most important clue, and manages to arrive on the scene just as the wife is about to murder Henrietta, the dead man’s mistress (who, along with the other members of the Angakell clan, has been protecting her.) Christie takes more time developing character in this book, and has some interesting things to say about the creative process via Henrietta, who is a sculptor, and the scientific mind, via Poirot (of course), John Christow, and John’s son Terence.
     Christie does some nice satire on the upper classes, and her portrait of Lucy Angakell, an amiable sociopath, is priceless. Other Christie motifs: the long shadows of the past, the plight of the working woman, the malign effects of over submissiveness, the nature of obsessive relationships, the persistence of feudal attitudes in modern England, and ironic but retributive justice (Gerda  dies by drinking the poisoned tea she intended for Henrietta).
     Very well done. Could make a very good three or four part series. This book marks the beginning of Christie’s late phase, when she allows herself the luxury of digressions and extended character portrayal instead of sticking closely to the puzzle plot. The effect is that the plot becomes more complex than the puzzle, which makes the book much more interesting. She doesn’t always carry it off (in her last books, she rambles too much), but when as here she integrates all the apparent digressions into the main line of the story, the result is very effective. ****

Smoking (and quitting)

For some reason, smoking came up in conversation this evening. At one time, I smoked 30 or more cigarettes per day. Today, that would cost me $12-$15 per day here in Ontario. Enough to buy a car.

I quite not by trying to quit, but by deciding I would not have the next cigarette. Within two weeks I was longer smoking, but I relapsed twice. Now I haven't had that next cigarette for forty years.

The Meme Machine (book)

Susan Blackmore The Meme Machine (1999). Blackmore explicates an extended version of Dawkins notion of memes. It constitutes a rough theory of memes. She starts by observing that humans are imitators -- in fact, other animals hardly imitate at all, and even the ones who do (e.g., parrots) imitate a limited range of behaviours, whereas humans imitate just about everything. She thinks this behaviour a) needs explaining; and b) has consequences. The consequence she sees are memes (short for mimemes). A meme is whatever a human imitates. It can be relatively simple (e.g., a handshake) or quite complex (eg, a song.) Memes can combine into memeplexes.
     The most significant aspect of memes is that by being imitated they are replicated. If we now look at things from their point of view, they are replicators -- and replicators inevitably evolve. Blackmore’s explanation of evolution from this p.o.v is excellent. She draws various conclusions, some of which are clearly testable (and she says so) and some of which aren’t. The most interesting general conclusions are as follows:
     First, that human culture is an effect of memes' evolution. Those memes that replicate successfully constitute the culture. And the culture changes because of course the replicators continually evolve. Humans continually invent new behaviours, because imitations aren’t necessarily exact, and memes may be varied or combined with other memes. Any new memes or variations of existing ones may (not) be easy to copy (whatever that means), so some new memes will proliferate at the expense of existing memes. Thus the culture changes. This is most obvious in the case of fashion, but can be seen in other aspects of culture.
     Second, that memeplexes may include memes accidentally, in which case these memes survive not by intrinsic merit but because they are dragged along by the successful replicators.
     Third, that the most successful memeplexes include religions.
      Fourth, that when memes first appeared, that is when humans became better imitators, whatever genes were implicated both in imitation and in improved survival of the imitators would also spread. This, she thinks, may account for both the very large human brain and for language. Both the large brain and the language are good for memes.
     Fifth, that memes may proliferate to the detriment of their carriers, and may therefore in the long term destroy their own vehicles.
     Sixth, that the self or ‘I’ is an illusion, a memeplex. From this last conclusion she speculates further that it is possible to live without this illusion, and points to various mystical traditions that say much the same thing. Her last chapter is a re-writing of Buddhist doctrine, and therefore also resonates with Christian and other mysticisms.
     A very interesting book, which I shall reread.

Money and Class in America (book)

Lewis Lapham Money and Class in America (1988) Lapham’s jeremiad against money worship in the USA. A text rich in anecdotes supporting statistical generalisations. Lapham was raised within an upper-class San Francisco family, and should have become another of the idle rich. Instead, he went to work as a journalist. His origins gave him unquestioned access to the rich, his work gave him opportunities to publish his observations. His subtitle is Notes and Observations on the Civil Religion, which indicates his thesis. The upper classes worship money; the rest of us have taken up the same faith.
     Lapham documents the corrosive effects of this worship, and I emphasise documents. The effects are in the first instance personal: money worshippers find themselves ever emptier of, and ever more hungry for,  the satisfactions they believe money will supply. But the upper classes are also the rulers, for they can suborn the democratic governments that could and should keep them in their place. And the upper classes are role models, so that the people ape their soi-disant betters, and fall into the same trap.
     Thus the effects of money worship are seen at every level – the personal, social, cultural, economic, and political. Lapham is too shrewd to claim that his thesis amounts to a  theory of American decline, and certainly doesn’t claim that it explains everything. But it explains a lot. The obvious parallels to Rome before the barbarian invasions and France before the Revolution are lightly sketched, but not less frightening than a thorough analysis would be – more frightening, in fact.
     Lapham writes well, and has a knack for the summary epigram and the bizarrely accurate simile. Eg, “[The rich man] never knows why other people do what they do because it never occurs to him that other people have obligations to anyone other than himself.”

      Update 2012:  Current reality is worse than Lapham foresaw.

This Immortal (Zelazny, 1966)

Roger Zelazny This Immortal (1966). A picaresque adventure, during which the narrator-hero is under surveillance (unbeknownst to him) to determine whether he would be the right person to “inherit” the Earth.

    Interesting background: A Three Day War has destroyed a large part of Earth, leaving Hot Spots and mutants, many of which resemble the creatures of myth. The off-Earth government wants to sell out to the Vegans, and become their servant class. The Vegans are an old and wise civilisation, and most of them behave ethically, too. The radical political party wants to eliminate the Vegans, whom they suspect of making a  catalogue of things to buy, and have a hired an assassin to do it. He and the hero are old friends; etc etc etc – lots of pseudo-portentous hero-type talk ensues. The hero also happens to be an immortal. 

     In the 60s, SF wasn’t very sophisticated, and far too much time is spent on gee-whiz heroics of the video game kind. Zelazny’s concepts are worth developing in a full scale future history series, but so far as I know he never followed up on this book. A fairly good read, especially the first half, in which the culture is presented and enough complications are started to serve a half a dozen novels. But it diminishes into a straight adventure-travel story. ** (2000)

The Early Orgins of Autism (Article

Patricia M. Rodier The Early Origins of Autism, Scientific American, 282/2 (February 2000), 56-63. Survey of several significant recent results: A) autists have large structural deficits in the brains stem (very small facial nuclei; absent superior olives; 0.2mm separation layer vs 1.1mm normal size.); B) these structural deficits imply damage of malfunction in fetal development in the 3rd to 4th week, early enough that most women do not even know they have conceived; C) Thalidomide victims have an incidence of autism some 30 times higher than in the general population; D) the low but significantly higher incidence of autism and autistic signs in families indicates that several genes are involved; E) One of the genes, HOXA1 has been identified.
     For me the most interesting finding is the atrophied facial nucleus. This bundle of neurons controls the facial and cranial nerves, and so is involved in facial expressions. Autists have poor or absent facial expressions; and they cannot read facial expressions in other people. This suggests to me that autists do not experience changes in facial expression that accompany changes in emotion; and so they have no subjective experience to relate to other people’s facial expressions. Thus, they do not respond to changes in facial expression, as normal babies do, and so they do not develop appropriate responses to the signs of emotion in other people. Note that Temple Grandin (an autist who has written a book about her life) remarks that she cannot recognise other people’s emotions - she must calculate or estimate them. She must also select the appropriate response expression (facial or verbal) from a consciously assembled catalogue.
     If the recent discoveries are supported in future research, the implications for understanding the relationship between genome and development are profound. Autists have a brain-stem deficit, which results in a behavioural deficit, which results in incorrect or inappropriate interaction with their environment, which results in incorrect (or unsuitable) response from their environment, and so on. It’s a kind of vicious circle. The deficit is augmented by the lack of environmental clues that might trigger the development that would (at least in part) make up for the deficit! One can generalise this idea to other phenomena quite easily. The basic idea is that the genome and the environment must interact correctly for normal development to take place. If the child is incapable of correct responses to the environment, the environment (ie, other people) will not interact appropriately with it, and so it will miss the environmental cues that guide normal development. There is some support for this hypothesis: eg, Downs syndrome children provided with simplified and exaggerated versions of suitable cues can and do develop much further towards normalcy than do children deprived of these cues. In fact, it seems that if they are provided with suitable cues, they usually reach the low-normal range of intellectual and the normal range of social functioning.  Great article. **** (2000)
