Easter Island – truly isolated

“These frozen faces … mark a civilization which failed to take the first step on the ascent of rational knowledge.” Bronowski said, “I am fond of these ancient, ancestral faces, but in the end, all of them are not worth one child’s dimpled face”, for one human child—any child—has the potential to achieve more than that entire civilization did. Yet “for most of history, civilizations have crudely ignored that enormous potential … children have been asked simply to conform to the image of the adult.” And thus ascent has been sabotaged or frozen.

The above quote is taken from David Deutsch’s admiring essay on Jacob Bronowski and his seventies science series The ascent of man, and it refers to the statues found on Easter Island (known to Polynesians as Rapa Nui) and to the culture that created them. Deutsch highlights the ‘ascent’ element of Bronowski’s series, and he elaborates further on this in his book The beginning of infinity, the central thesis of which – that humans are capable of more or less infinite development and improvement – I’m quite sympathetic to. However, in dismissing ‘the customary condescending doublethink towards primitive cultures’, of many anthropologists, and supporting Bronowski’s apparently wholesale contempt for the Rapa Nui statue builders, Deutsch makes a fatal error, the same type of error, in fact that Robert O’Hara Burke made in rejecting the advice and help of ‘mere savages’ who had learned, no doubt by painful trial and error, to survive more or less comfortably for millennia on the meagre resources of the desert environment of Central Australia. This example of cultural arrogance led directly to Burke’s death.

Now, to be fair to Deutsch, he fully recognises that he himself wouldn’t survive for long in central Australia’s hostile environment, or that of Saharan Africa, Mongolia, Antarctica or any other forbidding place. But I think he fails to sufficiently recognise that particular cultures, like species, adapt to particular environments, some of which are more static than others – but none of which are entirely static. That’s why I think Bronowski’s statement, that Rapa Nui’s statues and the massive platforms created for them, ‘mark a civilisation which failed to take the first step on the ascent of rational knowledge’ is both dangerously arrogant and false.

In trying to show why this is so, I won’t be indulging in any romanticised view of indigenous cultures. I come from a diverse and dominating culture that has discovered only recently, thousands of exoplanets, gravitational waves that Einstein postulated but never thought could be discovered, and the Higgs boson, a particle that I’m excited by even without having much idea of its nature or vital role in the cosmic structure. I should also mention our ability to create entire human beings from a single somatic cell, through induced pluripotency – and it may be that these astonishing achievements may be overtaken by others more astonishing still, by the time I’ve finished writing this work. But of course when I say ‘our’ achievements, I’m well aware of my non-role in all this. I’m a mere particle caught up and swept along in the tide of momentous events. I had no choice in being a Europeanised human male. I could’ve been born as an Easter Islander, or an Aboriginal Australian. Or indeed, as a bonobo.

The Rapa Nui population, as mentioned, seems to have reduced from its height, perhaps in the 1500s, to Roggeveen’s 1722 visit. However, there’s a more or less total lack of agreement about the extent of that reduction, and therefore, whether it could be said that the population ‘collapsed’. We do, know, however, that the increasingly frequent visits of European adventurers and traders from the late eighteenth century into the nineteenth had a devastating effect on Rapa Nui’s Polynesian inhabitants.

It’s difficult to get clear data on Rapa Nui culture, clouded as it is by the ideologies of different researchers, by the myths and legends of the islanders themselves, by the lack of written records and the difficulties of interpreting and dating remains, tools, ash-heaps and other artifacts. No sooner do I read material about the hierarchical and destructively competitive nature of the population, than I find recently researched material arguing for necessary co-operation in creating and moving their statues from one part of the island to another. As to the deforestation, some have argued they destroyed their trees for canoe-building and also for the purpose of transporting their statues, using log rollers. Others have tried to show that trees were not used for moving the statues as they were created to be transported upright, using ropes to shuffle them along on rounded bases. Others have argued that plant species on the island weren’t suitable for boat-building. It’s frankly hard to believe that these islanders, so attuned to their environment, would have engaged in the thoughtless or ‘irrational’ destruction of it that Bronowski et al accuse them of. The most recent analysis, published only a few months ago, paints a different picture:

During the last decade, several continuous (gap‐free) and chronologically coherent sediment cores encompassing the last millennia have been retrieved and analysed, providing a new picture of forest removal on Easter Island. According to these analyses, deforestation was not abrupt but gradual and occurred at different times and rates, depending on the site. Regarding the causes, humans were not the only factors responsible for forest clearing, as climatic droughts as well as climate–human–landscape feedbacks and synergies also played a role. In summary, the deforestation of Easter Island was a complex process that was spatially and temporally heterogeneous and took place under the actions and interactions of both natural and anthropogenic drivers. In addition, archaeological evidence shows that the Rapanui civilization was resilient to deforestation and remained healthy until European contact, which contradicts the occurrence of a cultural collapse. 

What is certain, as Diamond’s analysis has shown, is that the island was less hospitable than most for sustaining human life, and yet the Rapa Nui people endured, and, as the account left by Roggeveen and his men shows, they were hardly a starving, desperate remnant in 1722.

In the next part, I’ll look at the Ranga Nui people’s activities in providing themselves with the necessities before the eighteenth century, the tragedy of their post-European fate, David Deutsch’s treatment of the situation and … whatever.
