Excerpt from Chapter 14 – Sapiens: A Brief History of Humankind
Until recently, you would not have heard scientists, or anyone else, speak so bluntly. “Defeat death?! What nonsense! We are only trying to cure cancer, tuberculosis, and Alzheimer’s disease,” they insisted. People avoided the issue of death because the goal seemed too elusive. Why create unreasonable expectations? We’re now at a point, however, where we can be frank about it. The leading project of the Scientific Revolution is to give humankind eternal life. Even if killing death seems a distant goal, we have already achieved things that were inconceivable a few centuries ago.
In 1199, King Richard the Lionheart was struck by an arrow in his left shoulder. Today we’d say he incurred a minor injury. But in 1199, in the absence of antibiotics and effective sterilization methods, this minor flesh wound turned infected and gangrene set in. The only way to stop the spread of gangrene in twelfth century Europe was to cut off the infected limb, impossible when the infection was in a shoulder. The gangrene spread through the Lionheart’s body and no-one could help the king. He died in great agony two weeks later.
As recently as the nineteenth century, the best doctors still did not know how to prevent infection and stop the putrefaction of tissues. In field hospitals doctors routinely cut off the hands and legs of soldiers who received even minor limb injuries, fearing gangrene. These amputations, as well as all other medical procedures (such as tooth extraction), were done without any anesthetics. The first anesthetics—ether, chloroform, and morphine—entered regular usage in Western medicine only in the middle of the nineteenth century. Before the advent of chloroform, four soldiers had to hold down a wounded comrade while the doctor sawed off the injured limb. On the morning after the battle of Waterloo (1815), heaps of sawn-off hands and legs could be seen adjacent to the field hospitals. In those days, carpenters and butchers who enlisted to the army were often sent to serve in the medical corps, because surgery required little more than knowing your way with knives and saws.
In the two centuries since Waterloo, things have changed beyond recognition. Pills, injections, and sophisticated operations save us from a spate of illnesses and injuries that once dealt an inescapable death sentence. They also protect us against countless daily aches and ailments, which pre-modern people simply accepted as part of life. The average life expectancy jumped from around 25–40 years to around 67 in the entire world, and to around 80 years in the developed world.
How long will the Gilgamesh Project—the quest for immortality—take to complete? A hundred years? Five hundred years? A thousand years? When we recall how little we knew about the human body in 1900, and how much knowledge we have gained in a single century, there is cause for optimism. Genetic engineers have recently doubled the average life expectancy of Caenorhabditis elegans worms. Could they do the same for Homo sapiens? Nanotechnology experts are developing a bionic immune system composed of millions of nano-robots, who would inhabit our bodies, open blocked blood vessels, fight viruses and bacteria, eliminate cancerous cells, and even reverse aging processes. A few serious scholars suggest that by 2050, some humans will become a-mortal (not immortal, because they could still die of some accident, but a-mortal, meaning that in the absence of fatal trauma their lives could be extended indefinitely).
Whether or not Project Gilgamesh succeeds, from a historical perspective it is fascinating to see that most late-modern religions and ideologies have already taken death and the afterlife out of the equation. Until the eighteenth century, religions considered death and its aftermath central to the meaning of life. Beginning in the eighteenth century, religions and ideologies such as liberalism, socialism, and feminism lost all interest in the afterlife. What, exactly, happens to a communist after he or she dies? What happens to a capitalist? What happens to a feminist? It is pointless to look for the answer in the writings of Marx, Adam Smith, or Simone de Beauvoir. The only modern ideology that still awards death a central role is nationalism. In its more poetic and desperate moments, nationalism promises that whoever dies for the nation will forever live in its collective memory. Yet this promise is so fuzzy that even most nationalists do not really know what to make of it.
