Moon Meditations

One of the so-called anthropic coincidences is that in order for a planet to be capable of supporting life it has to have a moon the size and distance of our own in order to stabilize its axis. Some scientists have argued recently that this claim is exaggerated. Specifically, they argue that the larger planets in the solar system would have had a similar effect on the earth, preventing the earth's axis from fluctuating more than about 10 degrees, and that is not significant enough to prevent the existence of life. The earth -- and by extension, any potential life-site -- does not require a moon like the one we have. The article, unfortunately, does not cite a scientific study showing this, only that "astronomers at the University of Idaho have shown" it. Regardless, this is an interesting claim, since most of the studies on the anthropic principle have been in the direction of showing more numerous and more extreme examples of anthropic coincidences, so to have an example going the other way is intriguing. I mentioned this criterion in my series on the anthropic principle (part 1, part 2, part 3, part 4), but my focus on it was in the final entry where I pointed out that having a moon the particular size and distance of our own allows for scientific observation rather than the possibility of life.

Toby Huff's Dangerous Curiosity

Toby Huff’s last book The Rise of Early Modern Science: Islam, China and the West was a brave attempt to answer one of the most difficult questions that the history of science presents. Why, asked Huff, did the scientific revolution happen in the West rather than in China or the Islamic world? You might add ancient Greece and India to the list of places the scientific revolution didn’t happen.

Asking this and then answering it too made Huff wildly unpopular with some historians. He’s a sociologist himself which provided one convenient stick to beat with which to beat him. Other reviewers variously implied he was an imperialist or even a racist. His real crime was to suggest that there was something culturally important about the West that made its science more effective than anyone else’s. Huff, in other words, is an anti-relativist.

As someone who is quite comfortable with the idea that western civilisation is the best thing that has ever happened to human beings, I think Huff deserves serious attention. He asks a question that you are not supposed to ask and gives answers that enrage his opponents. I’m not going to deal here with where I agree and disagree with Huff on specifics. But I wholly support his project of a comparative sociological approach which asks what cultural features make a difference to the way that each civilisation does science. And he is absolutely right to say that modern science is the only science that gives us consistently accurate theories about nature.

Unfortunately, because The Rise of Early Modern Science was a book of grand themes and broad sweep, it also contained too many factual errors. Huff prepared a second edition that dealt with many of these, but the feeling remains that he did not lay sufficient empirical foundations to carry his thesis. Neither did Said, Frazer or Foucault (let alone Marx), but we’ll let that pass.

So Huff’s new book, Intellectual Curiosity and the Scientific Revolution: A Global Perspective (Cambridge 2011), is far more factual then his last one. In the first part, he looks at how the telescope was received in China, India and the Ottoman Empire. The story of the Jesuits’ effort to demonstrate the superiority of western science at the court of the Chinese Emperor is particularly fascinating. It was also amusing to hear that the first recorded instance of the telescope being used in Constantinople was to spy on the Sultan’s harem! Huff’s point is that the telescope did not kick off a new era of scientific research in other civilisations in the way it did in Europe. He puts this down to a lack of scientific curiosity, but wisely doesn’t try to explain what might have caused this.

The second part of the book compares the course of different sciences through the sixteenth and seventeenth centuries in Europe and elsewhere. A lot of the European material is very familiar, but it is enlivened by stories from elsewhere. But the central theme that European science cracked on at an increasing pace while the rest of the world showed little interest is forcefully made.

Its more modest ambition probably makes Intellectual Curiosity and the Scientific Revolution a better academic monograph than The Rise of Early Modern Science. But it is surely a lot less fun. Sacred cows litter the pages of the earlier book and it is so bracing to read a sociologist who is not caught in the headlights of political correctness. The combative Huff is less visible in the new book. It remains essential reading for all historians of science, but most of them will probably ignore it and hope that they can continue to avoid the difficult questions that Huff insists on asking.

You should be reading Maverick Philosopher if you're not already. It's written by Bill Vallicella who grew tired of academia and now expresses his masterful metaphysical musings online. For the neophytes, try starting with his posts on eliminative materialism.
