"[A]s well as seriously – indeed exhaustively – researching everything that could conceivably go wrong, I think we should also investigate what could go right. The world is racked by suffering. The hedonic treadmill might more aptly be called a dolorous treadmill. Hundreds of millions of people are currently depressed, pain-ridden or both. Hundreds of billions of non-human animals are suffering too. If we weren't so inured to a world of pain and misery, then the biosphere would be reckoned in the throes of a global medical emergency. Thanks to breakthroughs in biotechnology, pain-thresholds, default anxiety levels, hedonic range and hedonic set-points are all now adjustable parameters in human and non-human animals alike. We are living in the final century of life on Earth in which suffering is biologically inevitable. As a society, we need an ethical debate about how much pain and misery we want to preserve and create."
"Given our anthropocentric bias, thinking of non-human vertebrates not just as equivalent in moral status to toddlers or infants, but as though they were toddlers or infants, is a useful exercise. Such reconceptualisation helps correct our lack of empathy for sentient beings whose physical appearance is different from "us". Ethically, the practice of intelligent "anthropomorphism" shouldn't be shunned as unscientific, but embraced insofar as it augments our stunted capacity for empathy. Such anthropomorphism can be a valuable corrective to our cognitive and moral limitations. This is not a plea to be sentimental, simply for impartial benevolence."
"...it won't just be the quality and quantity of consciousness in the world that will be transformed in the post-Darwinian Transition. As (post-)humanity emerges from the neurochemical Dark Ages, enriched dopaminergic function in particular may sharpen the sheer intensity and meaningfulness of every moment of conscious existence. For a generation whose lifetimes span both modes of awareness, it will be as if they had just woken up. They will feel they had hitherto been sleep-walking through life in a twilit stupor. Thereafter their former mundane and minimal existence may be recalled only as some kind of zombified trance-state whose nature they were physiologically incapable of recognising..."
"Many city-dwellers have a romanticized conception of the living world. From another perspective, some "conservation biologists" favour e.g. "". By contrast, I think any truly compassionate person should be horrified at the terrible suffering of Nature "red in tooth and claw". Why not aim for a cruelty-free world instead?"
"No amount of happiness enjoyed by some organisms can notionally justify the indescribable horrors of Auschwitz. [...] Nor can the fun and games outweigh the sporadic frightfulness of pain and despair that occurs every second of every day. For there's nothing inherently wrong with non-sentience or [...] non-existence; whereas there is something frightfully and self-intimatingly wrong with suffering."
"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."
"Suppose we encounter an advanced civilization that has engineered a happy biosphere. Population sizes are controlled by cross-species immunocontraception. Free-living herbivores lead idyllic lives in their wildlife parks. Should we urge the reintroduction of starvation, asphyxiation, disemboweling and being eaten alive by predators? Is their regime of compassionate stewardship of the biosphere best abandoned in favour of "re-wilding"? I suspect the advanced civilization would regard human pleas to restore the old Darwinian regime of "Nature, red in tooth and claw" as callous if not borderline sociopathic."
"[L]ike nonhuman animals in human factory farms, free-living nonhumans who are starving - or being disembowelled, asphyxiated or eaten alive - cannot console themselves by chanting the Four Noble Truths of Buddhism. The moral case for helping other sentient beings, regardless or race or species, does not rest on the distress their plight does (or doesn't) cause spectators."
"All that matters is the pleasure-pain axis. Pain and pleasure disclose the world's inbuilt metric of (dis)value. Our overriding ethical obligation is to minimise suffering. After we have reprogrammed the biosphere to wipe out experience below "hedonic zero", we should build a "triple S" civilisation based on gradients of superhuman bliss. The nature of ultimate reality baffles me. But intelligent moral agents will need to understand the multiverse if we are to grasp the nature and scope of our wider cosmological responsibilities. My working assumption is non-materialist physicalism. Formally, the world is completely described by the equation(s) of physics, presumably a relativistic analogue of the universal Schrödinger equation. Tentatively, I'm a wavefunction monist who believes we are patterns of qualia in a high-dimensional complex Hilbert space. Experience discloses the intrinsic nature of the physical: the "fire" in the equations. The solutions to the equations of QFT or its generalisation yield the values of qualia. What makes biological minds distinctive, in my view, isn't subjective experience per se, but rather non-psychotic binding. Phenomenal binding is what consciousness is evolutionarily "for". Without the superposition principle of QM, our minds wouldn't be able to simulate fitness-relevant patterns in the local environment. When awake, we are quantum minds running subjectively classical world-simulations. I am an inferential realist about perception. Metaphysically, I explore a zero ontology [...] the total information content of reality must be zero on pain of a miraculous creation of information ex nihilo. Epistemologically, I incline to a radical scepticism that would be sterile to articulate. Alas, the history of philosophy twinned with the principle of mediocrity suggests I burble as much nonsense as everyone else."
"[O]ne might naively suppose that a negative utilitarian would welcome human extinction. But only (trans)humans - or our potential superintelligent successors - are technically capable of phasing out the cruelties of the rest of the living world on Earth. And only (trans)humans - or rather our potential superintelligent successors - are technically capable of assuming stewardship of our entire Hubble volume."
"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."
"In future, nerve cell responsiveness to naturally occurring endogenous opioids can be increased via receptor enrichment in the brain too. In principle, we can modulate their lifelong "overexpression", intermittently heightened (or gently diminished) by whatever kinds of personal and environmental contingencies we judge fit. Both functionally and anatomically, our reward pathways can be made "bigger and better". But intelligent emotional self-mastery will involve re-engineering the mind-brain so we derive the most intense rewards from activities we deem most lastingly worthwhile: i.e. prioritising our higher-order desires over legacy first-order appetites. Natural selection has "encephalised" our emotions to benefit our genes. Rational agents can "re-encephalise" our emotions to benefit us."
"[T]rue hedonic engineering, as distinct from mindless hedonism or reckless personal experimentation, can be profoundly good for our character. Character-building technologies can benefit utilitarians and non-utilitarians alike. Potentially, we can use a convergence of biotech, nanorobotics and information technology to gain control over our emotions and become better (post-)human beings, to cultivate the virtues, strength of character, decency, to become kinder, friendlier, more compassionate: to become the type of (post)human beings that we might aspire to be, but aren't, and biologically couldn't be, with the neural machinery of unenriched minds. Given our Darwinian biology, too many forms of admirable behaviour simply aren't rewarding enough for us to practise them consistently: our second-order desires to live better lives as better people are often feeble echoes of our baser passions."
"If we don't address the genetic causes of suffering (physical and mental) we will find ourselves in 500 years enjoying material abundance via nanotech, living in a perfect democracy, colonizing space, and still sitting around wondering "Why are we miserable so much of the time? Why can't we all just get along? Why are we not all happy?""
"Humans are prone to status quo bias. So let's do a thought-experiment. Imagine we stumble across an advanced civilisation that has abolished predation, disease, famine, and all the horrors of primitive Darwinian life. The descendants of archaic lifeforms flourish unmolested in their wildlife parks – free living, but not "wild". Should we urge scrapping their regime of compassionate stewardship of the living world – and a return to asphyxiation, disembowelling and being eaten alive? Or is a happy biosphere best conserved intact?"
"Today, status quo bias runs deep. Conservation biology is an ideology masquerading as a science. Many researchers seek to extend the tenets of conservation biology to humans. By contrast, a benevolent superintelligence might view Darwinian life on Earth as an infestation of biological malware and act accordingly. The amount of suffering caused by Homo sapiens is hard to quantify. But the suffering is immense and growing daily with the spread of industrialised animal abuse."
"[H]uman nature as encoded in our DNA isn't immutable. Mankind's barbaric track-record to date is an unreliable guide to the future. If Homo sapiens' nastier alleles and their more sinister combinations can be silenced or edited out of the genome, and new improved code-sequences inserted instead, then the pessimists will be confounded. A major discontinuity in the development of life lies ahead. Providentially, we've learned that the DNA-driven world isn't written in God-given proprietary code it would be hubris to tamper with, but in bug-ridden open source amenable to improvement."
"Confusion of sapience with sentience can be ethically catastrophic."
"Why expect a false theory of the world, i.e. classical physics, to yield a true account of consciousness?"
"To be sure, risks abound; but no one is proposing compassionate stewardship of ecosystems by philosophers. Humans are capable of choosing our own future pain-sensitivity too; but any species-wide genomic shift in human pain tolerance will depend on the willingness of prospective parents to use preimplantation genetic screening."
"Genes and culture have co-evolved. But crudely, natural selection "designed" male human primates to hunt nonhumans and build coalitions of other male human primates in order to wage territorial wars of aggression. Nature didn't design us to become a scientific community and collaborate to overcome aging. It's difficult to imagine that any human enemy could inflict such gruesome damage on the victims as growing old. The ravages of aging strike down combatants and civilians alike. So the trillions of dollars that humans currently spend on ways to harm and kill each other ("defence") would be more fruitfully spent on defeating our common enemy. We should work together to build a "Triple S" civilisation of superlongevity, superhappiness and superintelligence."
"It's easy to support the status quo if one is not another of its victims."
"[B]oth natural selection and the historical record offer powerful reasons for doubting the trustworthiness of our naive moral intuitions. So the possibility that human civilisation might be founded upon some monstrous evil should be taken seriously - even if the possibility seems transparently absurd at the time."
"So what is the alternative to traditional anthropocentric ethics? Antispeciesism is not the claim that "All Animals Are Equal", or that all species are of equal value, or that a human or a pig is equivalent to a mosquito. Rather the antispeciesist claims that, other things being equal, equally strong interests should count equally. Experiences that are subjectively negative or positive in hedonic tone to the same degree must count for the same."
"A few centuries from now, if involuntary suffering still exists in the world, the explanation for its persistence won't be that we've run out of computational resources to phase out its biological signature, but rather that rational agents – for reasons unknown – will have chosen to preserve it."
"The biology of suffering in intelligent agents is a deep underlying source of existential risk – and one that can potentially be overcome."
"What right have humans to impose our values on members of another race or species? The charge is seductive but misplaced. There is no anthropomorphism here, no imposition of human values on alien minds. Human and nonhuman animals are alike in an ethically critical respect. The pleasure-pain axis is universal to sentient life. No sentient being wants to be harmed – to be asphyxiated, dismembered, or eaten alive. The wishes of a terrified toddler or a fleeing zebra to flourish unmolested are not open to doubt even in the absence of the verbal capacity to say so."
"Getting rid of predation isn't a matter of moralising. A python who kills a small human child isn't morally blameworthy. Nor is a lion who hunts and kills a terrified zebra. In both cases, the victim suffers horribly. But the predator lacks the empathetic and mind-reading skills needed to understand the implications of what s/he is doing. Some humans still display a similar deficit. From the perspective of the victim, the moral status or (lack of) guilty intent of a human or nonhuman predator is irrelevant. Either way, to stand by and watch the snake asphyxiate a child would be almost as morally abhorrent as to kill the child yourself. So why turn this principle on its head with beings of comparable sentience to human infants and toddlers? With power comes complicity."
"I predict we will abolish suffering throughout the living world. Our descendants will be animated by gradients of genetically pre-programmed well-being that are orders of magnitude richer than today's peak experiences."
"All moral tradeoffs are messy. However, on some fairly modest ethical assumptions, when a severe and irreconcilable conflict of interests occurs, then the interests of the more sentient take precedence over the less sentient. This rule of thumb holds regardless of the age, race or species of the victim."
"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."
"Much more seriously, in those traditional eco-systems that we chose to retain, millions of non-human animals will continue periodically to starve, die horribly of thirst and disease, or even get eaten alive. This is commonly viewed as "natural" and hence basically OK. It would indeed be comforting to think that in some sense this ongoing animal holocaust doesn't matter too much. We often find it convenient to act as though the capacity to suffer were somehow inseparably bound up with linguistic ability or ratiocinative prowess. Yet there is absolutely no evidence that this is the case, and a great deal that it isn't."
"I think there's an asymmetry. There's this fable of Ursula Le Guin, short story, Ones Who Walk Away From Omelas. We're invited to imagine this city of delights, vast city of incredible wonderful pleasures but the existence of Omelas, this city of delights depends on the torment and abuse of a single child. The question is would you walk away from Omelas and what does walking away from Omelas entail. Now, personally I am someone who would walk away from Omelas. The world does not have an off switch, an off button and I think if one is whether a Buddhist of a negative utilitarian, or someone who believes in suffering-focused ethics, rather than to consider these theoretical apocalyptic scenarios it is more fruitful to work with secular and religious life lovers to phase out the biology of suffering in favor of gradients of intelligent wellbeing because one of the advantages of hedonic recalibration, i.e. ratcheting up hedonic set points is that it doesn't ask people to give up their existing values and preferences with complications."
"It's easy to convince oneself that things can't really be that terrible, that the horror I allude to is being overblown, that what is going on elsewhere in space-time is somehow less real than the here-and-now, or that the good in the world somehow offsets the bad. Yet however vividly one thinks one can imagine what agony, torture or suicidal despair must be like, the reality is inconceivably worse. The force of "inconceivably" is itself largely inconceivable here. Blurry images of Orwell's "Room 101" can barely even hint at what I'm talking about. Even if one's ancestral namesakes [aka "younger self"] underwent great pain, then the state-dependence of memories means that much of pain's sheer dreadfulness is semantically, cognitively and emotionally inaccessible in the here-and-now. So this manifesto's rhapsodies on the incredible joys that do indeed lie ahead tend to belie its underlying seriousness of purpose. For the biological strategy is propounded here in deadly moral earnest."
"If it is, then the sooner they give up the pretence of playing with public affairs and return to private life the better. If they cannot make a job of the House of Commons, let them at least make something of their own houses. If they cannot learn to save men from the destruction which incurable male mischievousness bids fair to bring upon them, let women at least learn to feed them, before they destroy themselves."
"The thought of the Upanishads is bold and free, and their general conclusion is that mystical experience is the pathway to reality."
"The civilizations of the East are very old; their roots stretch back into the past to a time when Europe was still a cockpit of fighting savages."
"Thus, the doctrines of Hinduism were never reduced to a set of formal creeds and Hindu religion has always been willing to receive new experiences and to incorporate new knowledge."
"Origen taught that all souls were created at the beginning of creation as angelic spirits. In this condition they sinned and for their apostasy were transferred into material bodies. It was this view of preexistence which was proclaimed heretical. In any case, heresy thus condemned so long ago need not be regarded today as of major importance. Truth matters a great deal more and a condemned heresy may turn out to be a truth, as happened, for example, when a local church of Rome condemned Galileo’s heliocentric doctrine and forced him to recant. Galileo was right and the church in question was wrong. It is therefore quite legitimate for both clergy and laity of the Christian faith to preach and believe in both preexistence and reincarnation."
"It should also be remembered that the Bible is written in the language of symbols, a special category of literature designed both to conceal and to reveal spiritual truths. Blindness is a symbol for temporary unawareness of spiritual light. The Christ partly represents spiritual intuitiveness. When one who is spiritually blind becomes intuitively awakened and active or, symbolically, enters the presence of the Christ and is healed by him, the scales are said to have fallen from his eyes. This I believe to be the true symbolical interpretation; for I look upon the story as one of the many beautiful miniature mystery dramas to be found in the Bible, portraying in allegory and symbol the soul’s awakening from darkness to light. Nevertheless, symbolism apart, the answer given by the Lord was, as stated above, doctrinally and technically correct."
"Members of the Christian faith sometimes object to the doctrine of reincarnation on the grounds that to accept it would be a violation of Christian doctrine. While it is true that a Council of Constantinople in the sixth century A. D. pronounced belief in the pre-existence of the soul to be heretical, an examination of the Scriptures strongly suggests that the doctrine of rebirth was generally accepted in those days and that Our Lord himself believed it. Whether this be the case or not, the student of the Christian doctrine may well ask whether a decision made by a group of men in the sixth century should be regarded as binding today."
"This objection to reincarnation by Christians, on grounds of doctrinal fidelity, is sufficiently important to merit a somewhat detailed examination. From this it is found that reincarnation has neither been proclaimed nor condemned by any general council of the Church or by any creed accepted by a general council. The Council of Constantinople held in 543 A.D., which proclaimed heretical Origen’s teaching of the preexistence of the soul and affirmed the doctrine of special creation, was not a general council, and so not universally authoritative."
"The disciples... asked the Master why it had been written that Elijah should appear first, and received a remarkable reply. St. Matthew records the incident thus: And his disciples asked him, saying, Why then say the scribes that Elias must first come? And Jesus answered and said unto them, Elias truly shall first come, and restore all things. But I say unto you, that Elias is come already, and they knew him not, but have done unto him whatsoever they listed. Likewise shall also the Son of man suffer of them. Then the disciples understood that he spake unto them of John the Baptist. (Matt. 17:10–13)"
"Reference has already been made to the command given by Christ to his followers: “Be ye therefore perfect, even as your Father which is in heaven is perfect” (Matt. 5:48). If man is granted but one life in which to accomplish this perfection, such attainment would be an impossibility for almost every human being; and Our Lord would have presented to mankind an ideal which is impossible of fulfillment. Since his wisdom was perfect, it is extremely unlikely that he would have taken this course. If, however, each man is granted almost unlimited time and every needed opportunity throughout successive lives in which to reach the goal which is set for him, then Our Lord’s words are less an injunction than a description of the destiny of every man. Indeed, in the original Greek and in the Revised Version, the behest becomes a simple statement of fact: “Ye therefore shall be perfect, as your heavenly Father is perfect.”"
"Finally, I think it would be a great tragedy if, because of E. L. Gardner’s attack upon C. W. Leadbeater, less notice were taken of the latter’s valuable writings, especially those which expound basic Theosophy, for he always wrote with rare lucidity. His unique contributions to the literature upon the spiritual life, the Path of Discipleship, the Masters of the Wisdom and the Great White Brotherhood of Adepts upon Earth, are not likely to be equaled in their power to transform people’s lives in this period of world history. With so many other revealers of spiritual and occult wisdom to mankind, he has been—and by E. L. Gardner is now—decried and assailed. For me, however, C. W. Leadbeater was a giant amongst men, a great teacher and light-bringer to mankind, and I am indeed grateful for this opportunity of adding my testimony to that of others who knew him far more intimately than ever was my own privilege."
"C. W. Leadbeater received two letters from one of the Masters, both being in solid, objective form and transmitted occultly from beyond the Himalayas. This being the case, neither Mr. Gardner nor anyone else can truthfully say that C. W. Leadbeater’s first contacts with the Masters were imaginary. The two letters were, and still are, physical objects now preserved in the archives of the Theosophical Society. Although a very great deal of what C. W. Leadbeater said and described is beyond my own limited experience, I am able to offer the testimony that I have independently become assured of the truth of certain of his teachings. The existence of the human aura, for example, and of the changes and conditions produced in it by both temporary and habitual feelings and thoughts, are undeniable facts for me."
"The reliability of the seership of C. W. Leadbeater has been challenged by E. L. Gardner, who has described the former’s occult experiences as being mere unconscious “thought-creations.” Since some members of the Theosophical Society have become very disturbed by this charge, I have decided, in response to many requests, to relate certain personal experiences which demonstrate to me that E. L.Gardner is in error. One of the accusations made by Mr. Gardner is that C. W. Leadbeater’s supposed contacts with the Masters of the Wisdom were largely imaginery, being the result of the unconscious projections of his own thoughts."
"Geoffrey Hodson, a theosophical writer, in his book The Hidden Wisdom in the Holy Bible, Vol. I, gives us excellent clues to the symbolic meanings of the Bible. One of his suggestions is that we look at many biblical passages not for historical information, but that we consider them as happenings within our lives..."
"The Hidden Wisdom and Why It is Concealed"
"The Bible as a whole is not written systematically, however, but is a collection of books of history, historical metaphor, biography, law and poetry, all leading into one another without an apparent plan. The Books of the Prophets include both historical narrative and an anthology of Divine revelations. Those of Joshua, Judges, Samuel and Kings tell the history of the Jewish people from Joshua’s conquest of the Holy Land to the destruction of the first temple by Nebuchadnezzar of Babylon in 586 B.C. These Hebrew prophets were the conscience of the people; for in the face of powerful priests and raving multitudes they spoke up with one chief purpose in mind—to teach man “to do justly, and to love mercy, and to walk humbly with thy God.” (Micah 6: 8). Isaiah writes with dignity and power, condemning social systems which forget the needs of the poor. Amos, a “herdman and a gatherer of sycamore fruit” (Amos, 7: 14), declared God’s judgment upon the nations and upon Israel, also foretelling Israel’s restoration. Jeremiah dedicated himself to God, but was despised and persecuted by the people. He called for peace when nations prepared for war, and demanded an inward religion of sincerity at a time when priests were enforcing their orthodox codes."
