A fixation on happiness inevitably amounts to a never-ending pursuit of “something else” — a new house, a new relationship, another child, another pay raise. And despite all of our sweat and strain, we end up feeling eerily similar to how we started: inadequate. Psychologists sometimes refer to this concept as the “hedonic treadmill”: the idea that we’re always working hard to change our life situation, but we actually never feel very different.

The reason the hedonic treadmill exists is because people aren’t taught how to be happy.

The Hedonistic Imperative outlines how genetic engineering and nanotechnology will abolish suffering in all sentient life.
This project is ambitious but technically feasible. It is also instrumentally rational and ethically mandatory. The metabolic pathways of pain and malaise evolved only because they once served the fitness of our genes. They will be replaced by a different sort of neural architecture. States of sublime well-being are destined to become the genetically pre-programmed norm of mental health. The world's last aversive experience will be a precisely dateable event.
Two hundred years ago, powerful synthetic pain-killers and surgical anesthetics were unknown. The notion that physical pain could be banished from most people's lives would have seemed absurd. Today most of us in the technically advanced nations take its routine absence for granted. The prospect that what we describe as psychological pain, too, could ever be banished is equally counter-intuitive. The feasibility of its abolition turns its deliberate retention into an issue of social policy and ethical choice.

The world is perhaps ultimately to be defined as a place of suffering. Man is a suffering animal, subject to ceaseless anxiety and pain and fear.

In the long run, there is nothing to stop intelligent agents from identifying the molecular signature of experience below hedonic zero and eliminating it altogether — even in insects. Nociception is vital; pain is optional. I tentatively predict that the world's last unpleasant experience in our forward light-cone will be a precisely datable event — perhaps some micro-pain in an obscure marine invertebrate a few centuries hence.

And to this world, to this scene of tormented and agonised beings, who only continue to exist by devouring each other, in which, therefore, every ravenous beast is the living grave of thousands of others, and its self-maintenance is a chain of painful deaths; and in which the capacity for feeling pain increases with knowledge, and therefore reaches its highest degree in man, a degree which is the higher the more intelligent the man is; to this world it has been sought to apply the system of optimism, and demonstrate to us that it is the best of all possible worlds. The absurdity is glaring.

We suffer for the simple reason that suffering is biologically useful. It is nature’s preferred agent for inspiring change. We have evolved to always live with a certain degree of dissatisfaction and insecurity, because it’s the mildly dissatisfied and insecure creature that’s going to do the most work to innovate and survive. We are wired to become dissatisfied with whatever we have and satisfied by only what we do not have. This constant dissatisfaction has kept our species fighting and striving, building and conquering. So no — our own pain and misery aren’t a bug of human evolution; they’re a feature.

When we combine the adaptation principle with the discovery that people’s average level of happiness is highly heritable,11 we come to a startling possibility: In the long run, it doesn’t much matter what happens to you. Good fortune or bad, you will always return to your happiness setpoint — your brain’s default level of happiness — which was determined largely by your genes. In 1759, long before anyone knew about genes, Adam Smith reached the same conclusion: In every permanent situation, where there is no expectation of change, the mind of every man, in a longer or shorter time, returns to its natural and usual state of tranquility. In prosperity, after a certain time, it falls back to that state; in adversity, after a certain time, it rises up to it.12 If this idea is correct, then we are all stuck on what has been called the “hedonic treadmill.”13 On an exercise treadmill you can increase the speed all you want, but you stay in the same place. In life, you can work as hard as you want, and accumulate all the riches, fruit trees, and concubines you want, but you can’t get ahead. Because you can’t change your “natural and usual state of tranquility,” the riches you accumulate will just raise your expectations and leave you no better off than you were before. Yet, not realizing the futility of our efforts, we continue to strive, all the while doing things that help us win at the game of life. Always wanting more than we have, we run and run and run, like hamsters on a wheel.

Certainly there would be no future suffering on earth if all life on earth ceased. But most people seem glad that they were born: we do not usually think of present people (and animals) that the pain in their lives outweighs their pleasures...There have been great advances in the human condition due to science: recollect the horrors of childbirth, surgical operations, even of having a tooth out, a hundred years ago. If the human race is not extinguished there may be cures of cancer, senility, and other evils, so that happiness may outweigh unhappiness in the case of more and more individuals. Perhaps our far superior descendants of a million years hence (if they exist) will be possessed of a felicity unimaginable to us.

The reason for sketching what's technically feasible with the tools of synthetic biology is that only after human complicity in the persistence of suffering in the biosphere is acknowledged can we hope to have an informed socio-political debate on the morality of its perpetuation. No serious ethical discussion of free-living animal suffering can begin in the absence of recognition of human responsibility for nonhuman well-being.

We did not make ourselves, nor did we fashion a world that could not work without pain, and great pain at that, with a little pleasure, very little, to string us along--a world where all organisms are inexorably pushed by pain throughout their lives to do that which will improve their chances to survive and create more of themselves. Left unchecked, this process will last as long as a single cell remains palpitating in this cesspool of the solar system, this toilet of the galaxy. So why not lend a hand in nature's suicide? For want of a deity that could be held to account for a world in which there is terrible pain, let nature take the blame for our troubles. We did not create an environment uncongenial to our species, nature did. One would think that nature was trying to kill us off, or get us to suicide ourselves once the blunder of consciousness came upon us. What was nature thinking? We tried to anthropomorphize it, to romanticize it, to let it into our hearts. But nature kept its distance, leaving us to our own devices. So be it. Survival is a two-way street. Once we settle ourselves off-world, we can blow up this planet from outer space. It's the only way to be sure its stench will not follow us. Let it save itself if it can--the condemned are known for the acrobatics they will execute to wriggle out of their sentences. But if it cannot destroy what it has made, and what could possibly unmake it, then may it perish along with every other living thing it has introduced to pain.

What is there in our nature that is for ever urging us on towards pain and misery?
