inspired by writers’ week, sort of – the internet, violence, testosterone and our future

Hmmm – needs further investigation. Vive les bonobos!
I spent some time at the Adelaide Writers’ Week tents yesterday, and heard a couple of remarks from speakers that exercised me in a negative way, so I thought I might air my grievances and expand on my thinking here. One was a quote taken, I think, from the historian and ‘public intellectual’ Bernard Lewis, on the influence of the internet on modern culture, and the other was a dismissal of the ‘better angels of our nature’ thesis of Steven Pinker.
I know Lewis only as a name, never having read any of his work, and I note that he died in 2018, just a few days shy of his 102nd birthday, so I can’t imagine him being an early adopter of the internet. I put his ‘public intellectual’ status in quotes largely out of jealousy, as I think I yearn to be a public intellectual myself, though I’m not sure. Anyway, from the little I heard of the quote, selected and spoken by Waleed Aly, Lewis was considering the double-edged sword of the internet in something like the manner of Marshall McLuhan in The Gutenberg Galaxy and The Medium is the Massage, only rather more negatively. I do recall dipping into McLuhan’s work decades ago, and finding it a bit over-hyped, and hyper. Anyway that’s enough of McLuhan. The concern being expressed about the internet was really mostly about social media and the ideological balkanisation it appears to foster. There’s some truth to this of course, which is why, without really thinking it through, I’ve been avoiding social media outlets more and more. Facebook lies dormant on my devices, and Twitter has come and gone.
But that is a minor part of the internet for me. Its advantages far outweigh the distractions of clickbait sites, and I personally consider it the greatest development in the dissemination of human knowledge at least since the invention of writing – and far more consequential than Gutenberg’s invention. For example, just in the past few months, without stepping outside my home, I’ve watched a lecture series from Yale University on the history of Russia, from the Kievan Rus to 1917 and the end of Tzardom; another lecture series – an Introduction to Neurology, from MIT, and a number of lengthy lectures from the Royal Institution, on palaeontology and on epigenetics, for example. I’ve subscribed to Brilliant.org and have completed 115 of their lessons on everyday science, and I’m boning up on the basics with Professor Dave’s Introduction to Mathematics series. Meanwhile, over the years I’ve observed Wikipedia growing in stature to become the first and best go-to site for learning about historical figures and events, as well as complex scientific subjects. And full scientific papers on just about every possible subject are becoming increasingly available online. I now have access to the greatest library in human history, which leaves me, at times, with a confused feeling – sometimes a dwarf, sometimes a titan. Bliss at this time it is to be alive, but to be young… I recall watching a video (online of course) about how a young African boy was able to build a wind turbine via online instructions, and so bring cheap electricity to his village. .. In short, the internet is an instrument – as is writing and the printing press. It can be used for a multiplicity of purposes, positive or negative. It’s up to us.
Second little irritant. I heard a brief segment of an onstage discussion between the philosopher and ethicist Peter Singer and a writer unknown to me, Samantha Rose Hill, author of a study on Hannah Arendt, about whether they viewed the future positively or negatively. Singer described himself as essentially an optimist, and spoke of his ‘expanding circle’ thesis. He also referred to Pinker’s The better angels of our nature, a book with which he was in broad agreement. The female writer, in her turn, said that she was definitely not in agreement with Pinker, after which I petulantly switched off.
I read The better angels of our nature, probably not long after it was published in 2011, and Pinker’s follow-up book, Enlightenment now, in 2018 or 2019. Right now I can say that I can’t recall a single sentence from either book, which is also the case for the hundreds of other books that have been consumed by the gaping maw of my mind. I might also say that I’ve written more than 800 pieces on this blog, and I’d be hard put to remember a line or two from any of them. In fact I’m sometimes moved to read an old blog piece – somebody has to – and find it amazing that I once knew so much on a topic about which I now know nothing.
But I digress. I don’t have to dig up my copy of Better angels to confirm my agreement with Pinker’s thesis. He wasn’t putting forward an argument that we’d become less violent as a species. He didn’t need to, because it was so obviously true, as anyone who reads a lot of history – as I do – knows full well. The real key to Pinker’s book lies in its sub-title, Why violence has declined. It seems to me that nobody in their right mind – or, I mean, nobody with an informed mind – would argue that the human world, a hundred years ago, 500 years ago, 1000 years ago, or, taking advantage of the knowledge provided to us from ancient DNA, 10,000 years ago, was more peaceful than it is today, on a per capita basis. The question is why.
Of course it’s impossible to keep track of the daily violent acts among a current global population of 8 billion, and to compare them to those of say, the year 1600, when the population has been estimated at about a half billion. And, yes, we’re now capable of, and have committed, acts of extreme, impersonal violence via nuclear weapons, but anybody who has read of the gruesome events of the Crusades, the Thirty Years War, the Scottish slaughters of England’s Edward I (a recent read for me), the centuries-long witch-hunts of Europe, and many other brutal engagements, as well as the public hangings, burnings, decapitations and tortures that were commonplace worldwide in earlier centuries, would surely not want to be transported back in a time machine without a cloak of invisibility or the support of a very powerful overlord – supernatural by preference.
Pinker’s book seeks to answer his own question with data and the possible/probable causal linkages, while recognising the complexity of isolating and independently weighing causes and correlations (he returns to this theme in his latest book Rationality, especially in the chapter entitled ‘Correlation and Causation’), including the spread of democracy, the growth of globalism and internationalism, the developing concepts of human rights, feminism, international monitoring agencies, and improved, less dangerous technologies re industry, medicine and transport, to name a few. Deaths can be no less violent, that’s to say violating, for being slow and accidental, after all.
Note that I snuck ‘feminism’ in there. Unsurprisingly, that’s the factor that most engages me. In the WEIRD world, thanks largely to Simone de Beauvoir (ok, a bit of flagrant heroine-worship there), feminism has been on the rise for several decades. During the same period, in the same regions of the world, male testosterone levels have been dropping. I would rest my case there, but I hear Mr Pinker tsk-tsking in the background. Seriously, the rise of feminism is surely one of a multiplicity of factors leading to a situation that medical researchers describe as ‘alarming’ – I’m not sure why.
Of course, testosterone is an important hormone, especially for men. On this medical website, Dr Kevin Pantalone, an endocrinologist, points out that, for males, testosterone helps maintain and develop:
- Sex organs, genitalia and reproductive function.
- A sense of well-being.
- Muscle mass.
- Bone health.
- Red blood cell count.
So, questions arise. Why are testosterone levels dropping (pace feminism), and is the drop significant enough to seriously compromise WEIRD men’s health? Well, according to the same website, different figures are given for what counts as a low testosterone level – 250 nanograms per deciliter (ng/dl), according to Dr Pantalone, and 300 ng/dl according to the American Urology Association. We’re not there yet, on average, but we’re inching closer, apparently.
So why the drop, apart from feminism? Some suggested factors include obesity (elevated BMI), reduced physical activity (however, endurance activities such as long-distance running and cycling have been shown to lower testosterone levels)., poor diet (but ‘several studies indicate that low-fat diets may lead to slightly lower testosterone levels‘), chronic and excessive alcohol consumption, lack of sleep (e.g. sleep apnea), and environmental toxins such as EDC (endocrine-disrupting chemicals – which sounds a bit vague).
That’s it. It all seems a bit thin to me – apart from the obesity bit. One factor they don’t mention, probably due to our overly polite society – or is it ‘wokeness?’ – is the serious drop in recent decades, and perhaps even centuries, of good old raping and pillaging. Nothing better for boosting ye olde testosterone, surely?
Seriously, would it be a terrible thing if male testosterone levels were reduced to those of females? And what about my darling bonobos?
So, human males typically have testosterone levels ranging from 265 to 923 ng/dl, while females range from 15 to 70 ng/dl. That’s a big big difference. Which raises the question – if females have such low testosterone levels, what about their bone health, muscle mass and sense of well-being? I suppose this is where we get into the finer details of endocrinology and evolution, but my uneducated guess would be that, over time, the endocrine systems of male and female humans have diverged somewhat, perhaps in response to different activities between the sexes. One way of getting more information about this – and this rather excites me, I have to say – is to look at the endocrine systems of largely female-dominated bonobos and compare them to those of chimpanzees. So that’s what I’ll be looking at in my next post. I can’t wait.
