Historical science

I have just finished Jared Diamond’s 1997 book Guns, germs and steel. The subtitle, A short history of everybody for the last 13,000 years, sums up a fascinating tale of not just our past but of the human condition. It is an extraordinary account of both the quirks of human history and the astonishing speed of our emergence to colonize and appropriate the planet.

You cannot go wrong with Diamond’s books. They are accessible, fluid and delivered, as one reviewer put it, with “a combination of expertise, charm and compassion.” The Third Chimpanzee and Collapse are popular science classics.

Although Diamond is a scientist, more precisely an evolutionary biologist, Guns, germs and steel is about history. A courageous attempt to describe and explain why in amongst all the movements of people some groups won, expanding territory and growing in number, while other groups lost, either by being overrun or exterminated.

Diamond’s science take seems to be fuelled by a sense of compassion. He flatly rejects racist explanations for success in favour of a more cause and effect analysis. The conclusions that technology (guns), the biological consequences of living in sedentary groups close to livestock (germs) and growing sufficient food to stay put long enough to work metal (steel) is convincing as it trots through 400 pages to a simple punch line.

But this is not to spoil the plot. It is the epilogue on history as a science that was the most intriguing.

Diamond leaves the detail of human occupation of every corner of the planet and makes a plea for science as knowledge. Science as a means to understanding that is more than the narrow view of controlled experimentation that is the essence of the scientific method.

His plea for historical science, an approach to history that is scientific in its logic. Only not of experimentation, for that is not possible, but for a sifting of the evidence that will allow for predictions and align cause.

This is curious because the book provides historical observation and interpretation that always suffers for want of attribution. It is odd that in an epilogue is a plea that draws attention to the core weakness in the argument. Observation is evidence but only in rare circumstances does it point to cause.

Cause must be surmised and then believed rather than proven in the way we can prove an experimental result.

Perhaps history is history, a catalogue of events and an interpretation of their meaning. And perhaps science is science only when attribution (a hypothesis) can be tested.

None of this makes Guns, germs and steel a lesser book, for the evidence and conclusions Diamond draws need to be read and heeded by us all.

Spongy attribution may explain why such books have only limited influence.

One thought on “Historical science

  1. Hi Mark
    I particularly liked the premise for writing the book which was the PNG guy asking – why are you here looking at my birds and not the other way round?

    I enjoyed the book thoroughly when it came out – the only issue I had with it was that I found the historical case he laid out was built around his theory and not the other way round! Similarly – Collapse – was again a case of proving what I thought was a limited point by choosing those civilisations and social orders that match his case for collapse.
    Good to read your thoughts anyway – will call you this week mate.
