I have written this essay for the Lancet Commission on the Value of Death. It is one of many background papers posted on the website of the Commission: https://commissiononthevalueofdeath.wordpress.com
I hope that you might like to subscribe to the site, encourage others to do so, and even comment on the papers that are there.
The Commission’s work is in progress, and we are keen to hear from others.
Our aim is to complete our work by the end of the year, submit it to the Lancet, and, we hope, publish it in June next year.
The pursuit of immortality
Consciousness of death is one of the attributes that sets humans apart from other animals, and the dream of overcoming death and living for ever may be as old as the consciousness of death: with the realisation came the dream. The world’s oldest story, the Epic of Gilgamesh, tells how Gilgamesh sought immortality, and the Ancient Egyptians believed that they could achieve immortality. The dream of immortality has stayed alive ever since, and Steven Cave, the philosopher, has identified four stories of immortality. https://bigthink.com/design-for-good/the-four-immortality-stories-we-tell-ourselves Modern technology and aspirations have boosted all these stories, and serious people with substantial resources believe it possible to achieve immortality.
Immortality Story I: The Elixir Story
Almost every culture at every time has a version of the story that some sort of magic elixir will not only allow us to live forever but keep us young. Leoš Janáček’s opera The Makropulos Affair tells the story of Elina Makropulos who in 1585 was given a potion that kept her young for 300 years and allowed her to become a great singer. But after 300 years she recognises that a shorter life offers a sense of purpose and transcendence that she has not had. As the effect of the potion fades she ages rapidly and offers the secret of the potion to a younger singer, who burns the parchment that contains the formula. The philosopher Bernard Williams used the story to illustrate his argument against mortality: for Elina her unending life has come to a state of boredom, indifference and coldness. Everything is joyless.” For her “singing and silence” are the same. https://wmpeople.wm.edu/asset/index/cvance/williams
Modern medicine has many variants on this story, with favoured technologies being nanotechnology, genetics, biological engineering, and regenerative medicine. For example, Robert A. Freitas Jr of the Zyvex Corporation writes about how with nanotechnology tiny robots will pass through our bodies, removing cancer cells, killing disease bacteria, and repairing any defects. http://www.rfreitas.com/Nano/Microbivores.htm#Sec5
Ray Kurzweil, who was once head of technology for Google, is co-author of Transcend: Nine Steps to Living Well Forever in which he argues that a combination of the right diet, vitamin supplementation, physical activity, and preventive medicine could keep us going until science has cracked the problem of immortality: “if you stay on the cutting edge of our rapidly expanding knowledge, you can indeed live long enough to live forever.”
Aubrey de Grey, Chief Science Officer of the SENS Research Foundation and Vice President of New Technology Discovery at AgeX Therapeutics, Inc, argues that humans can be kept going indefinitely just like cars by replacing parts as they wear out. William Haseltine, Chief Executive Officer of Human Genome Sciences, claimed in 1999 that “death is nothing more than a series of preventable diseases.” The Chan-Zuckerberg Foundation created by Mark Zuckerberg, the founder of Facebook, has a mission of curing all diseases. https://www.businessinsider.com/mark-zuckerberg-cure-all-disease-explained-2016-9?r=US&IR=T
The leaders in the pursuit of immortality are mostly well-funded companies from the West Cost of the United States. Such a pursuit sits comfortably alongside other HAGs (“hairy audacious goals”) like capturing all knowledge and building colonies on Mars. Success is far from guaranteed, and the endeavour seems like hubris to many—but these are serious people with large amounts of money pursuing immortality..
Immortality Story II: The Resurrection Story
The Resurrection of Christ is the most familiar version of this story, and it was Christianity’s promise of eternal life for all not just emperors that drew Romans away from their traditional gods to the new religion.
The Alcor Life Extension Foundation, https://alcor.org/ for example, has 151 “patients” with their heads or bodies deeply frozen, ready to be “resurrected” when medicine is able to cure the disease that killed them.
Cloning, which has already been done with sheep, is surely possible with humans and is another form of resurrection, although unless another method is found to achieve immortality will need to be repeated every 60 years or so. Cloning is medical science’s version of reincarnation.
Another medical variant on the story is the use of ECMO (Extracorporeal Membrane Oxygenation) to resuscitate people after a cardiac arrest. Sam Parnia, an intensive care specialist, writes in The Lazarus Effect “It is my belief that anyone who dies of a cause that is reversible should not really die anymore. That is: every heart attack victim should no longer die…heart attacks themselves are quite easily managed. If you can manage the process of death properly, then you go in, take out a clot, put a stent in, the heart will function in most cases. And the same with infections, pneumonia or whatever. People who don’t respond to antibiotics in time, we could keep them there for a while longer [after they had died] until they respond.”
Immortality Story III: The Story of the Soul
The concept of a soul, which St Augustine described as “a special substance, endowed with reason, adapted to rule the body” is common to many religions. It can survive the death of the body, and the modern version of this story is to “download” the contents of the brain into a computer. Carboncopies, https://carboncopies.org/mission/ another organisation based in California, aims to use whole brain emulation (WBE) so that “our thoughts and feelings will be able to exist on a variety of processing substrates. In that sense, we then have a substrate-independent mind (SIM). With advances in neuroscience and neural engineering we will be able to choose brain and body, much as we can choose winter or summer clothes to suit our needs.”
Immortality Story IV: The Legacy Story
This is perhaps the most familiar route to immortality—writing a great symphony or novel, winning a crucial battle, or making any great achievement that mean we will be remembered and celebrated for ever. A modern version of the story available to everybody is to create thousands of words and pictures on Instagram, Facebook, or any social media site. This may not allow the same immortality as painting the Mona Lisa, but it’s something.
A still more modern version is to create a “digital avatar” in which every bit of data from you (all that you’ve written and said, all words on you by others, etc) is used to create an avatar that will exist electronically and to continue you after you die. The more data the more the digital avatar will be “you.” The advantage of a digital avatar over a diary or a Facebook account is that gives you a continuing existence: you will be able to take place in family discussions, be interviewed on the radio, or even vote. A great many companies are in the business of creating digital avatars, although not simply for the preservation of individuals.
The idea of a digital avatar also opens up the possibility of “resurrecting” great minds of the past. The more data you have on a person the more likely that you will be able to resurrect the person: if we fed all the words of Aristotle, all the poems and plays of Shakespeare, all the poems and letters of Emily Dickinson into a computer we might create digital avatars of those great people. Perhaps too the data from Johann Sebastian Bach’s music, Titian’s paintings, or Alexander the Great’s battle plans would allow digital avatars of them.
A less grandiose vision of immortality
Cave argues that although it is natural to fear death it is not rational. He quotes Ludwig Wittgenstein: “Death is not an event in life: we do not live to experience death. If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those who live in the present. Our life has no end in just the way in which our visual field has no limits.”
Cave advocates thinking of life as a book that has the covers of birth and death but an infinity of possibilities within.
The Happy Death movement and immortality
The sociologist Lyn H Lofland in her book The Craft of Dying describes how what she calls the “Happy Death Movement” adopted immortality as one of its three components for giving meaning to death—the others were expressivity and passivity. Formed in the 60s the movement initially hinted at immortality but then adopted it wholesale. Perhaps surprisingly Dr Elisabeth Kübler-Ross, the doyen of Happy Death, believed in immortality.
“Dr. Elisabeth Kübler-Ross who has counseled thousands of terminally ill patients, is convinced that “people don’t really die.”
The 49 year old Swiss-born psychiatrist, author of On Death and Dying and two other books on death, says she knows “beyond the shadow of a doubt” there is life after death.
“This is not just the spooky stories of someone who has worked with too many dying patients, she said. “It is a good feeling to be able to say after many years that people don’t really die.” [“Specialist on Dying Says People Don’t,” Sacramento Bee, October 16, 1975]
Conventional medical research and immortality
Most of the organisations that talk explicitly of extending life and achieving immortality are companies, many on the West Coast of the US. But what about more conventional research organisations like the National Institutes of Health, the Medical Research Council, or the Wellcome Foundation? They don’t talk of achieving immortality, but at the same time they do talk of preventing and curing disease—and they don’t exempt any diseases. It is rational to think that their ultimate aim is to prevent or cure all diseases, including old age, which many researchers argue must be seen as a disease. Questions thus arise about whether, when, and how we will die. We asked some leaders of medicine and medical research for some answers, and some responded. (Table I)
Before considering their answers it’s worth noting that in 2014 (the last date for which complete data are available) Britain spent 0.13% (£3.24m) of its total spend (£3 billion) on end of life research compared with 16.9% on treatment, 5.27% on detection and diagnosis, 2.48% on prevention, and 34.69% on aetiology. http://hrcsonline.net/wp-content/uploads/2017/09/UK_Health_Research_Analysis_Report_2014_WEB.pdf
The answers from the leaders of medicine and medical research are politic. They are not as grandiose as to say that they are trying to cure all disease, but there are no diseases that they are not researching. When it comes to death and dying they have clearly thought little about them: their attention is elsewhere.
It is surely logical for members of the public who hear day after day medical researchers announcing new breakthroughs to think that eventually all diseases will be cured and that we will all live forever.
Critique of the pursuit of immortality
The most obvious criticism of the pursuit of immortality is that we already live on a planet that is unable to support all people in the lifestyle of those in high-income countries. We are not short of people, and do not need more needing feeding and consuming carbon.
This critique doesn’t, of course, apply to the notion of downloading brains or digital avatars. They would not need feeding and would consume minimal carbon (none at all with sustainable energy), but would we want the dead, including the long dead, to still be around? My daughter did not seem keen when I suggested that a digital avatar of me might continue to argue at the dinner table. The resurrected Shakespeare would surely be a diminished Shakespeare.
The second criticism is that all these technologies are expensive and would increase the gross inequality that currently exists in the world. The rich will live forever, while the poor may die younger in a world filled up with the immortal rich. Peddlers of immortality may argue that the technologies will become dramatically cheaper, allowing the rich and the poor to live forever. They might argue as well that it is both impossible and wrong to stand in the way of the human need to keep exploring, experimenting, discovering, and creating.
The critique of increasing inequality certainly applies to conventional medical research. The cost of health care consistently rises faster than inflation, meaning that health care costs consume an ever-larger proportion of gross domestic product—and innovation rather than aging of populations is the main driver of the rising cost of health care. Since the development of universal health coverage—for example, the NHS—the hope has been that the cost of care will come down, but it never happens. Because the cost constantly increases the “best care” is available to only a few—indeed, a shrinking few.
The possibility of immortality drives us back to consider the value of death—personal, human, social, cultural, philosophical, religious, economic, ecological, commercial, legal, and medical. Assuming that we can create for all some version of immortality, do we want to? Would we be creating heaven on earth or would it be hubris resulting in nemesis?

10,000 diseases. 500 treatments. Medical research offers hope to millions of people and there is certainly work to do. Yes cures for some but patients tell us they want a greater focus on quality of life improvements to help them live with their conditions. Essentially they want to live life well unencumbered by their illnesses. |
More research needs to focus on living well with multiple conditions as we age. It’s about quality of life not quantity. We will all die of something eventually. |
| Andrew Goddard
President, Royal College of Physicians,UK |
I think medical research should be to improve health rather than cure all disease. My understanding of survival curves of populations over time (Chris Whitty gave a fantastic Harveian oration on this a couple of years ago – http://www.clinmed.rcpjournal.org/content/17/6/537.short) is that they have pushed towards the top right corner of the graph with time but that the point of crossing the x-axis hasn’t moved much in the past 100 years. Thus we only get to live for our 100 years or so and that prolonging it much beyond that is not yet possible.
Over time we have made good progress in treating infectious disease (although AMR and climate change may undo that) and more latterly cancer so in the developed world the generations are now left with the diseases of degeneration. As I understand it we will all get senile amyloid eventually as we age, and its deposition in the heart is probably the terminal event in the truly ancient.
I think many would say that that there is a quality of years/quantity of years balance that needs to be met. I’ve had kidney cancer so was delighted medical research allowed that to be cured. However, if my remaining kidney was to succumb to another primary in 20 years time I would not want a lifetime of dialysis. Now if there were stem-cell grown kidneys available that would be another matter….. |
My answer to the first is no so 2 becomes defunct. |
| Derek Bell,
President, Royal College of Physicians of Edinburgh |
No and probably not possible |
I don’t need to answer but is the question here not disease but senescence |
| Jeremy Farrar
Director
Wellcome Foundation |
No.
Aims should be achievable and to cure all diseases (those known and those unknown to us now) is unrealistic and probably undesirable.
Some may not be curable, although we may not know which are and which are not.
Prevention is much more critical than cure.
Undertaking research across all conditions is justified, as we cannot know in which conditions prevention or cure is possible without research and in parallel understand how we might use that research to benefit the maximum number of people in the most equitable way possible.

I answered no, so not sure the question applies.
But I would say –
With dignity, respect and with well-being and quality of life paramount.
|
| Robert Lechler, president of the Academy of Medical Sciences |
Although medical research is looking to cure individual diseases, our bodies will still age and no amount of research can ever prevent the fact that we will all die of something. I think the aim of medical research is to ensure the years we live are spent in good health, and that when we reach the end of our lives we are supported to die as well as we possibly can.
“Death is something we will all experience, yet many people are uncomfortable talking about it, including doctors. But that shouldn’t stop us from doing medical research with the aim of understand how to care and support people to live well at the end of life.
The Academy of Medical Sciences recently carried out an ambitious public engagement project which attempted to break the taboo and encourage a national conversation about death and dying. It involved opening a shop called The Departure Lounge in a busy shopping centre. Here we were able to share information on end of life research and care in imaginative and engaging ways to encourage conversations about death while people were well, rather than when faced with the approaching death of a loved one.
“The Departure Lounge was a space where we heard time and time again that people valued a ‘good death’, over a longer life with time spent in poor health. This tells us that medical research needs to focus on improving quality of life at the end of life and narrowing the gap between wellness and death well before any attempts at a ‘cure for all’.” (Full response attached as an appendix)

“Alzheimer’s disease and other dementias claim the most lives in the UK. Out of the four leading causes of death, the mortality rate for dementia is the only one which has shown continual increase over the last decade.
“Multimorbidity, living with multiple serious, long-term health conditions, is also on the increase. Growing numbers of patients spend the last years of their lives struggling to manage several conditions at once. The global burden of people living with multiple serious illnesses must be urgently addressed. Without a better understanding of multimorbidity, it will not be possible for any country to plan future healthcare resources and redesign services effectively.”

- If so, how do you think that we will die?
- “The UK is reaching a tipping point. For many years, we have seen the annual number of deaths decrease, as scientific advances improve life expectancy. However, as the demographic bulge created by the baby boomer generation reaches its twilight years we need to prepare for an increase in annual deaths of those in their elderly years.
- “Alzheimer’s disease and other dementias claim the most lives in the UK. Out of the four leading causes of death, the mortality rate for dementia is the only one which has shown continual increase over the last decade. The World Health Organization estimates that the global number of deaths due to dementia will increase by over 40% from 2015 to 2030. Despite the work already in progress, it is clear dementia is an area still crying out for more research into prevention, treatment and care.
“Multimorbidity, living with multiple serious, long-term health conditions, is also on the increase. Growing numbers of patients spend the last years of their lives struggling to manage several conditions at once. The global burden of people living with multiple serious illnesses must be urgently addressed. Without a better understanding of multimorbidity, it will not be possible for any country to plan future healthcare resources and redesign services effectively.”
