Donald Mitchie: on Machine Intelligence, Biology & More

Donald Mitchie: on Machine Intelligence, Biology & More – Ashwin Srinivasan (ed.) ****

This is an eclectic collection of writings by and about Donald Michie, the Scottish-born scientist whose career spanned over half a century and covered many topics, most notably computer science and reproductive biology. Michie died in a car accident in 2007, aged 84, and “Machine Intelligence” is a tribute to his life and work compiled by the eminent computer scientist Ashwin Srinivasan.

The book varies widely in style and subject matter, but it is interesting and readable throughout. It comes in three parts, “Machine Intelligence,” “Biology,” and “Science and Society.” Each section is divided into chapters containing 3-5 pieces, with helpful introductions to the chapters by Srinivasan.

The writing is aimed at the non-specialist reader, and specialists may be disappointed by the absence of any of Michie’s many ground-breaking scientific papers. The upside is that experts and novices alike are treated to insider accounts of Michie’s code-breaking at Bletchley Park during WWII, reflections by Michie on how scientists work and the role of government in science, and thoughtful discussions of big topics in AI – such as the Turing test and the role of subconscious or “inarticulate” thought in cognition. Especially worthwhile are Michie’s thoughts on the difference between brute-force solutions to computing problems and truly intelligent solutions.

Michie was much more than a scientist, and some of the most witty and enjoyable writing in the book sees Michie as science administrator, social commentator, and popular science writer. Some of my favourites are his cutting comments on the Lighthill Report (the government report in the early 1970s that almost killed Britain’s nascent AI industry), his article about the reading habits of scientists (they do surprisingly little), and his account of a bizarre trek from London to Moscow that Michie undertook at the height of the Cold War.

“Machine Intelligence” is not a detailed or systematic treatment of Michie’s ideas – it’s a series of snapshots rather than a portrait. Articles on the same theme (like the difference between clever and intelligent computers) are sometimes scattered through the book rather than grouped together. And there are too many typographical errors. But “Machine Intelligence” succeeds as a readable tribute to a remarkable man, giving many glimpses of Michie’s insight, humour, and wide-ranging enthusiasm for science.

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

The Autobiography – Charles Darwin ****

I have to confess to putting off reading this book until the last moment, as I expected it to be a typical piece of Victorian sentimental unreadable stodge. I was wrong. Darwin’s little book (only 150 small pages with appendices) was originally written for his own children, and displays a very personal style of writing – though, as son Francis comments, his style was always more populist than was common then: “In writing he sometimes showed the same strong tendency to strong expressions that he did in conversation. Thus in the Origin, p440, there is a description of a larvel [sic] cirripede ‘with six pairs of beautifully constructed natatory legs, a pair of magnificent compound eyes and extremely complex antennae’. We used to laugh at him for this sentence, which we compared to an advertisement.” The main book is delightful because it demonstrates Darwin’s self-depreciating modesty, and the fascinating path he took from enthusiastic shooter of game, to amateur geologist (still his...

Zero Degrees of Empathy [The Science of Evil] – Simon Baron-Cohen ***

I’ve been a real fan of previous books by Simon Baron-Cohen like The Essential Difference , so opening this was one was a pleasant prospect. What I found was a book that wasn’t bad … but that could have been a lot better. I got the impression of a book that had been rushed out without a lot of work going into it. The thesis at the heart of the book – that one of the important ‘circuits’ of the brain is the one dealing with empathy, and that individuals sit on an empathy spectrum, with some residing at zero degrees of empathy – is an interesting one. Baron-Cohen introduces us to three key personality types he defines as ‘zero-negative’ including psychopaths, plus types that are ‘zero-positive’ like those with Asperger’s. In a way both of these definitions are odd, in that his zero-negatives can actually have a lot of the kind of empathy that involves being able to read another person’s emotional state, and his zero-negatives can have a lot of the kind of empathy i...
