Sapiens

Don’t believe tree-huggers who claim that our ancestors lived in harmony with nature. Long before the Industrial Revolution, Homo sapiens held the record among all organisms for driving the most plant and animal species to their extinctions. We have the dubious distinction of being the deadliest species in the annals of biology.

‘Happiness Begins Within.’ Money, social status, plastic surgery, beautiful houses, powerful positions – none of these will bring you happiness. Lasting happiness comes only from serotonin, dopamine and oxytocin.

A human handprint made about 30,000 years ago, on the wall of the Chauvet-Pont-d’Arc Cave in southern France. Somebody tried to say, ‘I was here!’

A chimpanzee can’t win an argument with a Homo sapiens, but the ape can rip the man apart like a rag doll.

Giving up the nomadic lifestyle enabled women to have a child every year.

Yet walking upright has its downside. The skeleton of our primate ancestors developed for millions of years to support a creature that walked on all fours and had a relatively small head. Adjusting to an upright position was quite a challenge, especially when the scaffolding had to support an extra-large cranium. Humankind paid for its lofty vision and industrious hands with backaches and stiff necks.

Women paid extra. An upright gait required narrower hips, constricting the birth canal – and this just when babies’ heads were getting bigger and bigger. Death in childbirth became a major hazard for human females. Women who gave birth earlier, when the infant’s brain and head were still relatively small and supple, fared better and lived to have more children.

We have mastered our surroundings, increased food production, built cities, established empires and created far-flung trade networks. But did we decrease the amount of suffering in the world? Time and again, massive increases in human power did not necessarily improve the well-being of individual Sapiens, and usually caused immense misery to other animals.

The most important impact of script on human history is precisely this: it has gradually changed the way humans think and view the world.

Consumerism has worked very hard, with the help of popular psychology (‘Just do it!’) to convince people that indulgence is good for you, whereas frugality is self-oppression.
