The Invention of Science by David WoottonThe Invention of Science: A New History of the Scientific Revolution, David Wootton (Allen Lane 2015)

I picked up this book expecting to start reading, then get bored, start skimming for interesting bits, and sooner or later give up. I didn’t. I read steadily from beginning to end, feeling educated, enlightened and even enthralled. This is intellectual history at nearly its best, as David Wootton sets out to prove what is, for some, a controversial thesis: that “Modern science was invented between 1572, when Tycho Brahe saw a new star, and 1704, when Newton published his Opticks” (introduction, pg. 1).

He does this in a clever and compelling way: by looking at the language used in science across Europe. If there was indeed a scientific revolution and science was indeed a new phenomenon, we should expect to see this reflected in language. Were old words given new meanings? Did new words and phrases appear for previously inexpressible concepts? They were and they did. “Scientist” itself is a new word, replacing earlier and less suitable words like “naturalist”, “physiologist”, “physician” and “virtuoso”. The word “science” is an example of an old word given a new meaning. In Latin, scientia meant “knowledge” or “field of learning”, from the verb scire, “to know”.

But it didn’t mean a systematic collective attempt to investigate and understand natural phenomena using experiments, hypotheses and sense-enhancing, evidence-gathering instruments. Science in that sense was something new, Wootton claims. He assembles a formidable array of texts and references to back his thesis, which is part of why this book is so enjoyable to read. As Wootton points out, the “Scientific Revolution has become almost invisible simply because it has been so astonishingly successful.” Quotations like this, from the English writer Joseph Glanvill, make it visible again:

And I doubt not but posterity will find many things, that are now but Rumors, verified into practical Realities. It may be some Ages hence, a voyage to the Southern unknown Tracts, yea possibly the Moon, will not be more strange then one to America. To them, that come after us, it may be as ordinary to buy a pair of wings to fly into remotest Regions; as now a pair of Boots to ride a Journey. And to conferr at the distance of the Indies by Sympathetick conveyances, may be as usual to future times, as to us in a litterary correspondence. (The Vanity of Dogmatizing, 1661)

Glanvill’s prescience is remarkable and he’s clearly writing in an age of pre-science or proto-science. He wasn’t just a powerful thinker, but a powerful writer too. So was Galileo and Wootton, who has written a biography of the great Italian, conveys his genius very clearly in The Invention of Science. You can feel some of the exhilaration of the intellectual adventure Galileo and other early scientists embarked on. They were like buccaneers sailing out from Aristotle’s Mediterranean into the huge Atlantic, with a new world before them.

Wootton also emphasizes the importance of Galileo’s original speciality:

The Scientific Revolution was, first and foremost, a revolt by the mathematicians against the authority of the philosophers. The philosophers controlled the university curriculum (as a university teacher, Galileo never taught anything but Ptolemaic astronomy), but the mathematicians had the patronage of princes and merchants, of soldiers and sailors. They won that patronage because they offered new applications of mathematics to the world. (Part 2, “Seeing is Believing”, ch. 5, “The Mathematization of the World”, pg. 209)

But there’s something unexpected in this part of the book: he describes “double-entry bookkeeping” as part of that mathematical revolt: “the process of abstraction it teaches is an essential precondition for the new science” (pg. 164).

He also has very interesting things to say about the influence of legal tradition on the development of science:

Just as facts moved out of the courtroom and into the laboratory, so evidence made the same move at around the same time; and, as part of the same process of constructing a new type of knowledge, morality moved from theology into the sciences. When it comes to evidence, the new science was not inventing new concepts, but re-cycling existing ones. (Part 3, “Making Knowledge”, ch. 11, “Evidence and Judgment”, pg. 412)

Science was something new, but it wasn’t an ideology ex nihilo. That isn’t possible for mere mortals and Wootton is very good at explaining what was adapted, what was overturned and what was lost. Chapter 13 is, appropriately enough, devoted to “The Disenchantment of the World”; the next chapter describes how “Knowledge is Power”. That’s in Part 3, “Birth of the Modern”, and Wootton wants this to be a modern book, rather than a post-modern one. He believes in objective reality and that science makes genuine discoveries about that reality.

But he fails to take account of some modern scientific discoveries. The Invention of Science is a work of history, sociology, philology, and philosophy. It doesn’t discuss human biology or the possibility that one of the essential preconditions of science was genetic. Modern science arose in a particular place, north-western Europe, at a particular time. Why? The Invention of Science doesn’t, in the deepest sense, address that question. It doesn’t talk about intelligence and psychology or the genetics that underlie them. It’s a work of history, not of bio-history or historical genetics.

In 2016, that isn’t a great failing. History of science hasn’t yet been revolutionized by science. But I would like to see the thesis of this book re-visited in the light of books like Gregory Clark’s A Farewell to Alms (2007), which argues that the Industrial Revolution in England had to be preceded by a eugenic revolution in which the intelligent and prudent outbred the stupid and feckless. The Invention of Science makes it clear that Galileo was both a genius and an intellectual adventurer. But why were there so many others like him in north-western Europe?

I hope that historians of science will soon be addressing that question using genetics and evolutionary theory. David Wootton can’t be criticized for not doing so here, because bio-history is very new and still controversial. And he may believe, like many of the post-modernists whom he criticizes, in the psychic unity of mankind. The Invention of Science has other and less excusable flaws, however. One of them is obvious even before you open its pages. Like Dame Edna Everage’s bridesmaid Madge Allsop, it is dressed in beige. The hardback I read does not have an inviting front cover and Wootton could surely have found something equally relevant, but more interesting and colourful.

After opening the book, you may find another flaw. Wootton’s prose is not painful, but it isn’t as graceful or pleasant to read as it could have been. This is both a pity and a puzzle, because he is very well-read in more languages than one: “We take facts so much for granted that it comes as a shock to learn that they are a modern invention. There is no word in classical Greek or Latin for a fact, and no way of translating the sentences above from the OED [Oxford English Dictionary] into those languages.” (Part 3, “Facts”, pg. 254)

He certainly knows what good prose looks like, because he quotes a lot of it. But his own lacks the kind of vigour and wit you can see in the words of, say, Walter Charleton:

[I]t hath been affirmed by many of the Ancients, and questioned by very few of the Moderns, that a Drum bottomed with a Woolfs skin, and headed with a Sheeps, will yeeld scarce any sound at all; nay more, that a Wolfs skin will in short time prey upon and consume a Sheeps skin, if they be layed neer together. And against this we need no other Defense than a downright appeal to Experience, whether both those Traditions deserve not to be listed among Popular Errors; and as well the Promoters, as Authors of them to be exiled the society of Philosophers: these as Traitors to truth by the plotting of manifest falsehoods; those as Ideots, for beleiving and admiring such fopperies, as smell of nothing but the Fable; and lye open to the contradiction of an easy and cheap Experiment. (Physiologia Epicuro-Gassendo-Charltoniana, 1654)

The Invention of Science is also too long: its message often rambles home rather than rams. If Wootton suffers from cacoethes scribendi, an insatiable itch to write, then I feel an itch to edit what he wrote. It’s good to pick up a solid book on a solid subject; it would be even better if everything in the book deserved to be there.

But if the book weren’t so good in some ways, I wouldn’t be complaining that it was less than good in others. In fact, I wouldn’t have finished it at all and I wouldn’t be heartily recommending it to anyone interested in science, history or linguistics. But I did and I am. The Invention of Science is an important book and an enjoyable read. I learned a lot from it and look forward to reading it again.

Neanderthal Man by Svante PaaboNeanderthal Man: In Search of Lost Genomes, Svante Pääbo (Basic Books 2014)

An excellent guide to science in all its aspects, from theory and practice to sociology and politics, describing how scientists think, work, live, love and sometimes cheat. It’s a book about bones, but it made me think about stars. In the nineteenth century, Auguste Comte set an absolute limit on the ambitions of astronomy:

On the subject of stars, all investigations which are not ultimately reducible to simple visual observations are … necessarily denied to us. While we can conceive of the possibility of determining their shapes, their sizes, and their motions, we shall never be able by any means to study their chemical composition or their mineralogical structure … Our knowledge concerning their gaseous envelopes is necessarily limited to their existence, size … and refractive power, we shall not at all be able to determine their chemical composition or even their density… I regard any notion concerning the true mean temperature of the various stars as forever denied to us. — Comte quote

Comte seemed completely right, but was in fact completely wrong. Fraunhofer had already discovered his lines by then and one day astronomers would be using “spectroscopic fingerprints” to “determine the mineralogy of asteroids, the composition of stars, the gravity of white dwarfs, the motions of galaxies, the dynamics of accreting black holes, and more – all from the comfort of a telescope control room” (30-Second Astronomy, ed. François Fressin, 2013).

Comte could have easily have said something similar about palaeontology, but perhaps it seemed too obvious. How much would scientists ever discover from ancient bones? They could weigh them, measure them, compare and contrast them, even analyse their chemical composition, but what would bones ever tell us about the flesh that had once sat on them, about the behaviour of vanished bodies? Very little, it once seemed.

A lot, it turned out, because of something called DNA. This book is about one of the most interesting projects in scientific history: the quest to reconstruct the genome of those long-extinct humans called Neanderthals. Except they’re not entirely extinct, as Svante Pääbo discovered: their genes live on in some modern humans, because we interbred with Neanderthals when we left Africa. Some of us also interbred with a group called the Denisovans, as Pääbo describes too. And there are other groups of archaic interbreeders to be uncovered, inside and outside Africa. Groups of human have separated, evolved differences, and then come together again, but not consistently and completely.

This has big implications for human bio-diversity, or HBD: races are different not just because they’ve evolved to be, but because they’ve interbred to be. Pääbo doesn’t discuss those implications, but there’s no propaganda here about “One Race – the Human Race”. The journey he and his team have begun is going to end in storm and lightning, because Neanderthal genes are doing more than stick around for the ride. They must have physiological and psychological effects, separating those who possess them from those who don’t. Ditto for the Denisovans and others.

So the search isn’t over and this book will have sequels. I look forward to reading them, because Pääbo writes well and engagingly in what isn’t his mother-tongue. Born in Sweden, he’s now “director of Department of Genetics at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany”. For an evolutionary anthropologist, he’s very famous: “In 2009, Time named him one of the 100 Most Influential People in the World”. He describes how he got there, the compromises he had to make and the toes he tried – and sometimes failed – to avoid treading on. But it’s mostly a story of obsession and ingenuity: Pääbo was obsessed with reconstructing a Neanderthal genome and had to be highly ingenious to do so. Luck and hunches were important too:

Most labs discard side fractions as by-products. Fortunately we had saved all of ours from our previous experiments. For years I had insisted on doing so, just in case something came along that would make them useful. This was easily one of my least popular ideas and caused many freezers to be filled with frozen side fractions that no one thought would ever be used. But thankfully in this case the crazy idea of the professor had been adhered to by the group. So now Tomi could simply heat the side fractions from earlier preparations from the Vindija bones and retrieve additional, relatively copious amounts of Neanderthal DNA without having to do any more extractions. (ch. 13, “The Devil in the Details”, pg. 145)

Pääbo is writing a popular account, so there isn’t a lot of technical detail, but there’s more than enough to be impressive. Genetics isn’t stamp-collecting: it requires serious intellect and nowadays serious computer-power and programming too. Pääbo couldn’t do all of that on his own: modern science is a collaborative endeavour. He directs a team and this book describes their ingenuity and idiosyncrasies. But in a way they’re a burial party. Science is now measuring mankind for its coffin. The more we know about ourselves, the more we will be able to surpass ourselves. This book about an obsessive human is also an early obituary for the human race.
