Who are sentientists? Who is involved in the sentientism movement and which organisations work on sentientist causes?

You can meet some sentientists on our "I'm a sentientist" wall and even add yourself if the philosophy fits personally. We're also building a list of Suspected Celebrity Sentientists - some of the names might surprise you. You can suggest others using our "I know a Sentientist" form here.

Millions of people around the world are sentientists, in that they are committed to evidence and reason and grant moral consideration to all sentient beings. Many of them will identify as atheists, secular humanists, skeptics or free-thinkers who take animal ethics seriously, but most of them haven’t yet heard of the term “sentientism”.

If approximately 10% of the world's population (~780 million) are atheists or secular humanists and around 10% (~780 million) are ethical vegans or vegetarians (as a proxy for meaningful moral consideration for sentient animals), that would imply there are around 78 million people whose worldview is fairly close to sentientism.

In practice, anecdotal evidence indicates that humanists and atheists are more likely to be vegan or vegetarian and vegans and vegetarians are more likely to be atheists or humanists. Of course, some atheists have other non-deity supernatural beliefs so aren't sentientists. Also, many vegans or vegetarians might have other rationales beyond compassion for sentients.  

You can find some sentientists in our various online communities. So far, people from around 70 countries, some on every habitable continent, are involved.

This web-site is run by me, Jamie Woodhouse. Here's my personal web-site and I am on Twitter @JamieWoodhouse.

The following section sets out some organisations and groups that link to sentientist themes and campaigns:

The Sentience Institute: Expanding humanity's moral circle. The Sentience institute isn't explicitly sentientist, although it is committed to the use of evidence and reason in its work to help extend humanity's moral circle to all sentients - primarily farmed animals.

Sentient Media: Reporting on animals, animal rights and human choices. Sentient Media isn't sentientist with respect to naturalism and the supernatural, but shares a sentientist objective re: helping extend our moral circle to include sentient animals.

Sentience Politics is a political think tank working to reduce suffering for non-human animals, with a focus on publishing policy papers and launching political initiatives in Switzerland and Germany. They're not sentientist with respect to naturalism and the supernatural, but share a sentientist objective of reducing suffering for sentient animals.

Philosophical Disquisitions: Is Effective Altruism ...

Effective Altruism is a movement trying to answer one simple question, using evidence and reason: how can we use our resources to help others the most? Then following that through into action. While many EA causes are focused on humans, others explicitly address the experiences of all sentient beings. EA is also not explicitly sentientist re: naturalism and supernaturalism (there are many religious effective altruists) - but it is committed to the use of evidence and reason in its work.

The Animalist

The Animalist: Rational arguments for extending Humanism to sentient animals. A logical, friendly and pragmatic approach to animal advocacy. Animalism is a very similar philosophy to Sentientism in that it retains the humanist commitment to evidence and reason but extends moral consideration to all sentient animals. Many animalists would likely also grant consideration to non-biological sentients if we were to encounter or create them.

The Reasoned Vegan

The Reasoned Vegan: The Reasoned Vegan is a project dedicated to making vegan advocacy more effective, more scientific, and less stereotypical. They promote and encourage skepticism, scientific understanding, and humility in all things vegan.

Rem Secora Pearl

I am a sentientist because I believe that no living being is inherently more valuable than another based on immutable traits: race, gender, age, or species. The value of life stems from pleasure, so to enslave or kill a being which can feel pleasure, or might be able to in the future (note that this includes nonsentient embryos and fetuses, but not a being which is braindead or cannot feel) is to rob it of all potential future pleasure.

Through a synergy of studying Marxism-Leninism and Secular Buddhism, I became interested in maintaining a meaningful worldview consistent with Buddhist compassion and Marxist dialectical materialism. After reading Althusser’s arguments for anti-humanism, as well as national books by Dean Cornish and Caldwell Esselstyn, I became interested in a naturalistic philosophical approach to veganism. This had to lead me to learn about sentientism, which compliments my views in Marxism and Buddhism, as well as minimalism, science, socialism, and environmentalism practices and activism.

Floris van den Berg

"I am a sentientist because: Suffering matters to those who suffer. Sentientism means having compassion for all those who suffer – both human and nonhuman. Sentientism means emancipating all sentient beings who can’t stand up for their own interests. Sentientism is the new moral paradigm. Change will not come by doing nothing. Sentientism is not only a theoretical idea, it includes veganism. Sentientism doesn’t hurt you – nor others.”

Floris's bio states he is "a philosopher and therefore an atheist". He is a practical, activist, vegan philosopher. He has written a number of books including "Philosophy for a Better World", "On Green Liberty", "De vrolijke veganist" ("The Happy Vegan") and "Hoe komen we van religie af?" ("How to get rid of religion. An inconvenient liberal paradox"). In 2017, Floris participated in a television series "To Hell With Your Religion", in which he lived with a group of people of various religions for two weeks, exploring and critiquing religious ideas.

Mel Dawson

Sentientism, like veganism for me, is very much a guiding principle in life. It came to me as a revelation in my late teens, that life choices held such hypocrisy. I found myself in turmoil over consuming some animals, whilst protecting others. I began to question the disparity around the world, the human injustice & wanton exploitation of the natural world. I realised I was a believer in sentientism fundamentally...that I was seeking to make decisions based on best insights into science, evidence, reason and supported with a compassionate disposition. It came natural to me, as I chose veganism. Understanding that all life has an innate right to exist..that it is not our place to attribute a 'scale of value' to beings, with humankind at the peak. Sentientism is the ultimate liberation from the man-made tyranny of rigid belief systems. It is simply 'freedom'.

His self-published internet manifesto, The Hedonistic Imperative, outlines how pharmacologygenetic engineeringnanotechnology and neurosurgery could converge to eliminate all forms of unpleasant experience from human and non-human life, replacing suffering with "gradients of bliss".

I'm a Sentientist because its what makes sense and we will need this shift if we are to survive as a species



I'm a sentientist because we should not be inflicting, without necessity, great suffering upon others. It is that simple. We should instead try to reduce and minimize the amount of suffering — no matter who is the being who's suffering — through, among other things, cultivating unbounded reason and unlimited compassion.

Dominique Ghijselinck

Humanity should come out of the human-centric bubble. However, too often animals are viewed with partisan sentimentality or ignorant disregard, as economic utility or nuisances. I think we need to be guided by evidence-based reason, wonder, care & curiosity to restore the bond with our beautiful world and minimize all suffering. If we judge ourselves to be capable of any moral progress, we will understand the need to live without being a threat to all living creatures around us.

Why I’m A Sentientist:

- No sentient being deserves to be treated as a commodity.

- Existing treatment is neither necessary for survival or morally justifiable.

- Cognitive science will continue to expand our understanding of the many forms of sentience.

- Recognizing our underlying genetic unity (ex. LUCA) is reason enough to universalize our compassion.

Sentientism- not only feels right, but actually is one of the most reasonable and convincing concepts I have ever come across

Alex Egorov


Jeroen Willems

It is my core value that every sentient being deserves a good, happy life. Whatever their race, religion, class, gender, sexuality or species may be. I want their suffering to stop. Reason and evidence is a must when trying to solve questions on how to help those who suffer, to discover who is suffering and how they are suffering. I prefer sentientism over animalism because it doesn't limit our moral circle to animals, but opens it to any kind of being who may be able to feel pain.



Jack Geiger

I care deeply about both rationality and ethics. My ethical foundation is exactly identical to the fundamental tenants of Sentientism. My conclusions and my ethics as a whole seem to differ slightly, but we start from a very similar set of principles.

All beings want to live.



Michael Keller

Because an unexamined life, is not worth living.


Bernard van Tonder

I selected all sentient perceptual experience as my ultimate ethical value after studying philosophy and completely rebuilding my ethical beliefs without previous dogmas. It came as a result of thoughts that emerged around the being-for-itself concept in Jean-Paul Sartre's Being and Nothingness book and Peter Singer's work. Consequently I have become an act utilitarian, vegan and an effective altruist. The concept has had a profound impact on my significant long-term decisions. I am confident that the world would be significantly better for everyone if everyone valued sentient experience, maximised positive perceptual experience and minimised negative perceptual experience.

As someone who is personally against bigotry, speciesism seems like a combination of racism, sexism, and ableism combined. I see no reason why someone that has the mental capabilities of a 3-5 year old (ex, pigs) should be treated the way they are simply because they have a body that does not look like a monkey, as ours does. If monkeys (homo sapiens) deserve rights and to live (as I believe they do) free of discrimination despite mental or physical differences, then why is someone to be judged on their worth for having feathers or hooves when we've already determined that judging someone on their bodily abilities and appearance is not justification for denying them personhood rights? It would be ethically inconsistent to be speciesist while claiming to be antiracist, antisexist, and/or antiableist.

If you take a moment out of your busy day to think about life on Earth, it's obvious that all sentient life whether arachnids, mollusks, reptiles, insects, birds, mammals, amphibians (in no particular order) is pretty miraculous. Who am I, (as a mammal), to say that my life is more valuable that that of an insect. All sentient life is caring, feeling and complex.

United Kingdom


I've considered myself a secular Humanist for the past 35 years or so, but at an even younger age, before the double digits, I felt that the injustices to other sentient beings, for example the suffering of laboratory animals for the benefit of humans and the rape of rain forests and indigenous peoples, was and still is a terribly myopic view of our role as part of life on Earth, and a completely unfair imbalance in favor of one species, or nation, at the detriment to all other sentients. I feel it's natural that these two philosophies are part of one way.

United States

Rom 2050

Suffering in any sentient being, even if not human, is still suffering. If our aim as individuals and society is to be "good", in any kind of definition possible, elimination of suffering is needed.




If our ability to suffer doesn't count for anything, then we could cause the greatest pain/suffering and yet not be held accountable. What decent morality maximizes suffering?

I believe our views should be based on naturalistic exploration of our universe, and that the most rational foundation for morality is the suffering and flourishing of sentient beings.

challenges both religion and anthropocentrism. He describes his own journey from religion, through atheism and Humanism and on to Sentientism. In the video he says, "I consider humans in my moral framework because they have the capacity to suffer  - and now, I consider other animals in my moral framework for the same reason." While continuing to agree with the core tenets of Humanism (evidence, reason and a focus on human wellbeing), he says "I do like the labels of Sentientist and ethical vegan." He calls for the end to all animal exploitation, including animal agriculture.

I am a Sentientist because of an inner strong compulsion to express my real human nature. The one that acknowledges that we are not the pinnacle of this planet. We are not superior by any means. We are just a part of life's web. And we have the potential to shift from being destructors and conquerors to being nurturers and regenerators. To respect and care for all sentient beings including our own kind.


Eva Hamer

Eva Hamer chained to and seated against a wall speaking into a megaphone

Eva is the operations lead for the non-profit Pax Fauna. Pax Fauna exists to design a more effective social movement for animal freedom in the U.S., using original research as well as careful study of social movement literature and the recent history of the animal movement in order to reverse the cultural norm of eating animals. Eva has been organizing in the animal freedom movement since 2015 when she started working with DxE in Chicago, where she focused on building community, writing protest music, and compiling the movements’ songs into an online songbook used by advocates around the world. She started working full time as DxE’s legal coordinator in 2018, managing the organization’s many legal cases, organizing trainings, and orchestrating large artistic demonstrations. Eva has a deep curiosity about culture in all its forms, and how social movements engage with culture both internally and externally. Through songwriting, she has explored how music and art can shape the messaging and attitudes of the animal movement. Building on a background in Kingian nonviolence, she is a dedicated student of Nonviolent Communication, and she is committed to bringing NVC’s repertoire of creative problem-solving tools to the work of building a better culture in the animal movement. Working for years as a music therapist in hospice taught Eva how to apply metrics to aspects of life that are difficult to measure- and how to judge when metrics aren’t working to tell the whole story.

Richard Ryder

Richard Ryder

Richard is a writer, psychologist, and animal rights advocate. He coined the term "speciesism" in 1970 and was one of the first to use the term "Sentientism" in a positive light, after it was first used in a derogatory sense by John Rodman in 1977 to criticise Peter Singer and Richard's thinking.

Richard developed the term sentientism in a naturalistic context – using evidence and reason to infer sentience and to grant moral consideration to sentient beings. Richard still considers himself a Sentientist in this naturalistic context today. He has also developed painism, a sub-set of the sentientist worldview that focuses on the moral importance of pain over that of positive experiences and aims to resolve the tensions between rights and utilitarian approaches.

Although I gave up meat many years ago it was relatively recently that I learned more about the exploitation and cruelty in the agricultural industry, that meant dairy cows as well as though bred for meat were often treated badly and would be killed after a few years, often male dairy calves are merely useless to them so they can be sent to the veal trade? Surely even worse than eating meat. As well as avoiding animal tested make up and skin care I try to join the animal rights community in signing petitions, raising awareness of cruelty from Taji dolphin hunting to the UK badger cull, which again is linked to practices in the dairy industry, intensive farming has spread BTB in cattle yet badgers are blamed, why? There are so many MPs in the Conservative DEFRA who are pro hunt and shoot it is hard to find a voice, but hopefully with platforms like this change is coming. The Dominion attitude has reigned for too long, even though I'm not an atheist and believe in Jesus Christ, I also think that it is human attitudes that have led to so much cruelty to people outside the West and animals in the serach for new territory and riches, a way of living alongside nature not owning it should be our goal as more sustainable peoples have known for centuries.

Kevin Saldhana

We seem to have developed a different attitude to sentient animals based on their utility (or competition) to humans as written about by Jonathan Foer in 'Some we love, some we hate, some we eat'. Others, as a means of defense, attribute sentience to plants. If we are serious about Humanism, we need to understand that, as rational beings, we have to extend our circle of compassion to those who we exploit including enslaving companion animals for our own enjoyment.

From a Sentientist viewpoint, I think that caring for animals is the only way to build a more humane and moral world for all sentient beings. Evidence, reason and compassion are the tools that the intelligence of the brain and the heart are having to know that animal sentience is as obvious as ours."

The universe has no obligation to make sense to us or to aid us in our search for and actualization of good. Sentience itself wasn't evolved out of any good will towards us subjects but as an instrument of Nature to keep on replicating. As beings capable of self reflection and radical transformation of our environment, we have the responsibility to use that power to benefit the totality of sentient experience.

If an organism seeks to avoid death and can suffer pain--even if not nerve-based as that which we are accustomed to--it is sentient and should be accorded rights. Both nonhuman animals as well as other intelligences, even if their origin may have been artificial.

I've chosen to follow this idea because I believe all life is worthy of freedom, happiness, and love with very general intrinsic value surviving in a world which they choose to avoid death and suffering as far as practicable, I also think it's very anthropocentric to trivialise the exploitation of non-human animals as commodities simply because they're different forms of life. We should really put into regard that these are sentient beings who feel pain, emotion, and nonsensically & unnecessarily suffer everyday for the sake of human gratification.

I have one challenge as a moral being, to draw a line, in pencil, between what is a someone and what is a something. Along that messy line, the more certain I am that another is a someone, the less like an object, and the more like an equal subject I must treat them.

All the sentient creatures of the earth are deserving of equal treatment.

Louis Gough

Although sceptical about the capacities of human reason, I do feel reason should be utilised by humans when making ethical decisions. Reason has thus far indicated to us that, alongside humans, nonhuman animals are sentient. Based on this knowledge, coupled with a rejection of (or ongoing attempt to reject) deluded and destructive anthropocentrism, I feel the least we can do as human beings is behave compassionately toward nonhuman animals (and fellow humans). The practice of veganism is a moral imperative in this connection.

Peter is often referred to as the “world’s most influential living philosopher.” He is the Ira W. DeCamp Professor of Bioethics at Princeton University. He specialises in applied ethics, approaching the subject from a secular, naturalistic, utilitarian perspective. He wrote the books "Animal Liberation", Why Vegan? and "Animal Liberation Now!"

He also wrote the essay "Famine, Affluence, and Morality" and the books "The Life You Can Save" & "The Most Good You Can Do" which argue for effective altruism - using evidence & reasoning to do the most good we can for all sentient beings both human and not.

In 2004 Peter was recognised as the Australian Humanist of the Year by the Council of Australian Humanist Societies. In 2005, the Sydney Morning Herald placed him among Australia's ten most influential public intellectuals. Singer is a cofounder of Animals Australia & the founder of The Life You Can Save.

In 2021 he received the Berggruen Prize for Philosophy and Culture. Peter donated the $1 million prize money to the most effective organizations working to assist people in extreme poverty and to reduce the suffering of animals in factory farms.

In Sentientist Conversations we talk about the two most important questions: “what’s real?” & “what matters?”

Sentientism is “evidence, reason & compassion for all sentient beings.” The audio is on our Podcast here on Apple & here on all the other platforms.

We discuss:
00:00 Welcome

  • Animal Liberation Now! – why now?
  • Sentientism's links to ancient naturalistic and sentiocentric themes of thought & Peter's work
  • Sentientism's 1) naturalism, 2) sentiocentrism & ethical pluralism, 3) implications of not needlessly harming or killing
  • "What needlessly killing amounts to… is a question… that could have a lot of discussion"
  • "In terms of what really matters in itself I agree that Sentientism is the right view"
  • The challenges of the words speciesism & sentientism - too many syllables!
  • Peter's entry on our "I'm a Sentientist" wall

06:12 What's Real?

  • Non-religious Jewish parents "they came to Australia as refugees from the Nazis, leaving Austria"
  • Mother "a fervent agnostic… there isn't reason to believe in a god or a supernatural being or life after death"
  • "In some parts of the United States it's almost necessary to belong to a religion to have a community"
  • Rabbi cousin in Mobile, Alabama "When I say god I mean whatever it is in the universe that is a force for good… (e.g. some human beings)"
  • "I kind of thought of them as fairy stories"
  • Childhood meeting with Catholic kids "don't ask him any more questions - he'll only blacken his soul & go to hell… I wasn't in the least frightened"
  • Good aspects of religions: "they tend to promote charity to the poor" (zakat, tithing)
  • Negative aspects of religions: Religious wars & "very often a conservative force against what I see as progressive reforms"
  • "If there were no religious teachings against #abortion I don't think the US would be divided over the issue"
  • Voluntary assisted dying "fortunately that legislation is spreading"
  • Why religious organisations get social licence to continue #sexism , #homophobia , #transphobia
  • "[Religious] teachings about sex which have been a very negative influence… making people feel guilty"
  • "The highest rate of unwanted teenage pregnancies in the US is precisely in the most religous parts"… rejecting contraception ("that would be sinful" - sex outside of marriage), getting pregnant, then facing abortion prohibitions
  • #Descartes was a sentiocentrist (but thought only "ensouled" humans can suffer). That's why you need naturalism too!
  • "I think consequences matter" #consequentialism & #utilitarianism
  • "Perhaps you want to embrace people who are religious & who are sympathetic towards animals & bring them towards #sentientism ?" The work of Andrew Linzey, Charles Camosy, David Clough
  • Previous guest Lisa Kemmerer
  • #Sentiocentrism vs. #Sentientism as #Anthropocentrism vs. #Humanism
  • "I totally agree with you about the value of evidence & reason"… #effectivealtruism
  • Religious effective altruists use evidence & reasoning but "would leave evidence & reason at the door for some of their specifically religious beliefs"
  • JW: "If we acknowledge the validity of unfounded beliefs in some domains it can make it a little harder to push back on them in domains where we're really worried about the effects"
  • Postmodernism & standpoint epistemology
  • “I was certainly very hard on Christianity… Aquinas said… we do not have any direct duties to them [animals] because they do not have souls and are not made in the image of god” [in the 1975 Animal Liberation]. “I’ve taken a slightly softer line in Animal Liberation Now!”

26:25 What Matters?

  • Working with Peter’s father: honesty & reputation “In the long run it would have good consequences”
  • “Brought up with a sense of not inflicting suffering on sentient beings… although we were big meat eaters”
  • Being invited to go fishing with friends. Father: “Do you really want to catch these fish up and wash them slowly die in the air?”
  • “There was definitely a concern for non-human animals but not to the extend of enquiring too much about how they were reared & killed”
  • The badness of suffering vs. nihilism, relativism
  • Reading Bertrand Russell “Within humans he was clearly… concerned with minimising suffering and maximising happiness”
  • Criticisms of utilitarianism: JW: “A disconnection from the individuals concerned… containers of utility… replacement, aggregation, offsetting”?
  • “We do have to aggregate… but I don’t think that should prevent us from empathy with individuals”
  • “Utilitarianism does accept that sometimes you have to allow or even cause suffering to one person to prevent more suffering to others… but the idea that we don’t then have empathy for the people who suffer”
  • “…Utility is a liquid that we pour into more containers… that seems to me to be wrong… suffering & happiness always are instantiated in one sentient being… no such thing as pleasure & pain floating around the universe unattached to a sentient being.”
  • “Offset“ suffering still exists!
  • Some effective altruists “but why does it follow that I should be vegan… maybe it would be more effective… to give to an effective charity fighting for animals?”… “Well why not do both?”
  • Going vegan “not only reduces demand for meat… but it sets an example & it makes it more likely others will… as in fact I did by having lunch with one.”
  • Testing people’s animal ethics by applying them to human animals

38:58 Who Matters?

  • “Those initial seeds [of compassion for non-human sentients]… failed to germinate for a very long time… I’m not at all proud of that”
  • “I became a vegetarian after accidentally having lunch with a vegetarian… I was 24 at the time… I had never had a serious conversation with a vegetarian about why they were vegetarian”
  • “I don’t know that I’d even met a vegetarian… for young people today that is unthinkable… there are vegetarians everywhere… vegetarian options on the menu…”
  • “I was already studying ethics… I should have questioned the boundaries of moral concern many years earlier”
  • “It was a bit of a shock… I’d never seriously enquired into what animals are going through to be turned into meat.”
  • “I assumed the animals I was eating had generally had a reasonably natural, tranquil, protected life and then had one bad day”
  • “Eating meat every day… & not really enquiring what happens to the animals… looking back on it now it’s shocking but… it was the default”
  • Philosophy, psychology, sociology, politics: “There’s a long history of humans believing what’s convenient for them to believe” e.g. Jefferson and US enslavement
  • “We find it convenient… we don’t want to go against social norms…”
  • The “future generations will condemn us (but I’m still not going to change)”
  • Using reason & evidence to attribute sentience “it’s changing right now” e.g. UK legislation extending sentience attribution to invertebrate cephalopods (e.g. octopuses) & decapods (e.g. lobsters & crabs) based on Jonathan Birch’s LSE ASENT research
  • Bivalves, insects, even plant sentience? “I’ve taken the possibility of plant sentience more seriously in the new edition… I’m still guessing not because there isn’t a brain or a central nervous system… but I’m less certain”
  • Philosophy of mind: illusionism, panpsychism…
  • “I’ve not gone deeply into panpsychism… I see no reason for believing that electrons or quarks could be sentient”
  • “A reasonably complex organism… some kind of brain & nerve centres… the more complex it is the more likely it is that there’s sentience… correlates with more complex behaviours”
  • Insects: “Such a huge variety… it seems very unlikely the answer is yes or no” e.g. bees vs. mealworms
  • Previous guest Luke Roelofs - Could “micro-conscious” entities be insentient (no perceptions, sensations, thoughts…) – only “macro-conscious” entities are
  • The first uses of the word “Sentientism” by Rodman & Lewis to criticise sentiocentrism as another form of human discrimination
  • Biocentrism & ecocentrism. Arne Naess. “There are a lot of people who want to find intrinsic value in nature… I am somewhat uncomfortable… I really enjoy being in nature…”
  • The ethereal experience of walking in an ancient forest with family “It somehow strikes me that it would be a kind of vandalism to chop it down”
  • Wouldn’t a consistent ecocentrist care about a lifeless/sentientless planet as much as ours?
  • When environmentalism’s disregard for non-human sentients exposes underlying anthropocentrism
  • The environmental impact (emissions, pollution, energy, land use) of animal agriculture “environmental groups are now serving more vegan food when you go to their events”
  • “It’s a wasteful system because we have to grow so many crops to feed to these animals… and we get back… maybe 10%”
  • Considering agency, dignity as other characteristics beyond sentience?
  • “This idea that there’s some special dignity about human beings… that does not apply to any non-human animals - is really groundless”
  • “Some animals have agency in ways that some humans don’t”
  • Agency as a basis for blame, punishment, praise, encouragement “that works with those who are agents and especially with agents with whom we can communicate”
  • Agency “is relevant in that sense… but it’s a different question… from does this being have intrinsic value… and I don’t think you need agency for that… our own infants… it’s clear they don’t have agency – but does that mean that their suffering doesn’t matter?”
  • Future guest Nicolas Delon re: agency as a way of extending moral consideration beyond sentience

01:10:05 How Can We Make A Better Future?

  • The “Animal Liberation Now!” clarion call re: rejecting speciesism, recognising equal consideration of like interests, for “liberation” vs. ideas of “humane killing”, “conscientious omnivorism”, focusing on factory farming & suffering reduction
  • JW: The risk of an end state “where we’ve actually got a larger animal agriculture system… where more animals are being killed & exploited & imprisoned… but we’ve found some way to re-brand these exercises as humane, high-welfare, sustainable… and on we go!”
  • “My clarion call is really clear against suffering & exploitation – it’s not so clear… about death”
  • “Sometimes it’s good for someone to die… when for example they’re suffering & their suffering can’t be alleviated… With humans… we would generally ask for their consent… but parents should sometimes be able to make that choice on behalf of their child (euthanasia for profoundly disabled infants)”
  • Compassionate euthanasia without consent for non-humans (e.g. companion animals)
  • Free-ranging hens living happy lives: “Is it a bad thing to have hens who live for a certain number of years and are then killed? – I find that a difficult philosophical question…”
  • A positive life on condition you are killed vs. not existing at all?
  • Derek Parfit’s “Reasons and Persons” & population ethics
  • “I’m genuinely uncertain about those arguments in respect of issues about humans and I’m therefore equally uncertain about them in respect to non-human animals”
  • Kazuo Ishiguro’s novel “Never Let Me Go”
  • JW: “As soon as we have created it (them), I think we then have a moral obligation to that being as a moral patient which means that to kill them against their interests… their interests in continuing to live… is just a wrong thing… regardless of whatever deal we’ve done with ourselves in advance”
  • “But then of course we won’t have any more chickens” JW: “I’m totally comfortable with that… The chicken that doesn’t exist isn’t a sentient being so isn’t a moral patient so cannot be harmed.”
  • “We do have a genuine disagreement… I’m much more ambivalent on that question than you are”
  • Peter’s “One World” book re: global governance
  • “We have to try everything… using evidence & reason”
  • Peter’s study with Eric Schwitzgebel – student meal choices were affected by exposure to animal ethics
  • Alternative proteins at scale; plant-based or cellular
  • Campaigning for improved farmed animal conditions: “the evidence suggests that those countries that have the best animal welfare standards… also have the highest rates of vegan & vegetarian living… it will increase the price of meat… that will make it easier for these alternatives to compete with meat.”
  • Re-writing the Universal Declaration of Human Rights and the SDGs from a Sentientist perspective: A Universal Declaration of Sentient Rights?
  • “We do need stronger global institutions… we seem to have moved away from stronger global institutions”
  • Effective Altruism: doing the most good possible using evidence & reason
  • Challenges to effective altruism (beyond do-gooder derogation): disconnection from the individual, demandingness & maximisation risks, ends/means, unintended consequences, neo-liberal / tech solution / NGO bias vs. state / democratic, corporatisation of philanthropy, eurocentrism, welfarism, the book “The Good It Promises, The Harm It Does”…?
  • “A lot of those challenges are based on misunderstandings of the movement… I think it’s very open to what is the best thing to do”
  • “They’re very open people – and if somebody comes out with a hypothesis… they will certainly look at that”
  • Poverty: “Just to say it’s global capitalism seems to me very simplistic – there’s been poverty long before there was global capitalism and there’s poverty in places where they’re not very much affected by global capitalism… and I haven’t seen anybody give any good accounts for how they’re going to get rid of global capitalism… but if somebody does come up with a plan… effective altruists will be very open to that.”
  • Europe/US/Global North/West: “That’s where a lot of the resources are… a lot of people that can help others in need. The largest numbers of people in extreme poverty are in the ‘south’”
  • “The groups that are supported by effective altruism don’t just march in to communities and say ‘this is what you need’… some of them, for example GiveDirectly, don’t even want to tell them how to spend them money… they want to increase their money” JW: “Trusting the people you’re trying to help”
  • “I reject the idea that this is… ‘a white saviour complex’… you ask the people in these impoverished villages whether they would like to have assistance and they say ‘yes’. If they didn’t say ‘yes’ then you wouldn’t do it.”
  • “I’ve met some truly wonderful people through effective altruism… they are both altruistic and often very thoughtful… it’s inspiring… donating money or time… donating a kidney to complete strangers!”
  • “During COVID it was effective altruists (One Day Sooner) who organised the volunteers for human challenge trials… if we get a vaccine one day sooner it will save lives… they were prepared to be infected with COVID… then they would get a candidate vaccine… in order to speed up vaccine development… There was a surprising amount of reluctance to… accept what they were asking to do for the world”
  • “It’s clear that philosophy can change the world”
  • People making positive changes after reading Animal Liberation & The Life You Can Save

Dogs and pigs have meaningful lives! - Philosopher Michael Hauskeller - Sentientism Episode 155

Find our Sentientist Conversation here on the Sentientism podcast and here on the Sentientism YouTube.

Michael is head of philosophy at the University of Liverpool. His current work spans transhumanism, death and meaning. He has written on whether non-human animals can have meaningful lives and What It Is Like to Be a Bot. He says of his work: “As a philosopher, I am a generalist, which is a nice way of saying that I have done many different things and I am not really an expert on anything in particular. Most people would probably tag me as an ethicist, but this is only true in a very broad sense. Figuring out what is right and what is wrong, permissible or impermissible, does not hold much interest for me. It seems to me that when people are debating these questions they are actually arguing about something else, namely who we want to be and in what kind of world we want to live. For me, doing philosophy is ultimately a sustained attempt to get to grips with this “deeply puzzling world” (to borrow an expression of Mary Midgley’s), to understand it and to understand our place in it. Philosophy is not business; it’s personal, more akin to therapy than to science. It’s about finding out what is actually going on and what we are doing here. Can philosophy provide an answer to these questions? I don’t know. All we can do is keep on trying. Perhaps what matters is not that we find an answer, but that we keep the question alive.”

In Sentientist Conversations we talk about the two most important questions: “what’s real?” & “what matters?”

Sentientism is “evidence, reason & compassion for all sentient beings.” The audio is on our Podcast here on Apple & here on all the other platforms.

We discuss:

00:00 Welcome
01:42 Michael's Intro

  • What it means to be human, to live a good life, a meaningful life
  • Transhumanism & human enhancement
  • Meaning & life & death
  • When dealing with foundational, broad questions: "It is very difficult to be precise… I hardly ever feel that 'now I've got it'"

06:06 What's Real?

  • "It's much easier to point at something & disuss whether that is real"
  • "If you can name something then in some sense it must be real"
  • Raised #Christian & sent to Sunday school & Bible classes & regular confessions to the village priest
  • "I sort of believed there was a god when I was little"
  • A god watching me "a means of controlling me… Big Brother in heaven… it was just oppressive… a punishing god, a critical god"
  • "I didn't feel the presence… I just believed that there was something because I was told there was something"
  • "Very quickly I dropped my religious beliefs… as soon as I started to think for myself I became an #atheist"
  • "It just faded away… it was always superficial"
  • "Some people take me for a Christian because I share some of the intuitions religious believers have"
  • "I'm not entirely comfortable with calling myself a naturalist although I don't believe in anything supernatural"
  • "Naturalism is also very programmatic & ideological"
  • "There are a lot of things in this world that we cannot understand…& some naturalists are very confident that we can understand everything & that's there's no mystery… there is a lot of mystery."
  • Max More's #transhumanism … pits science vs. religion
  • Origins of the universe & life & consciousness "we don't know!" Science might figure it out - it might not
  • "… whatever there is is part of nature"
  • Over-confidence vs. humility
  • The subjective & the objective
  • Plato & Parmenides: "being is more real than becoming"… "but we live in a world of becoming… how can that be less real?"
  • The "normative use of reality"… to "declare something else as not real… a term to deny something else its reality"
  • The denial of animal suffering "not so common any more" & the #cartesian model
  • "If you see an animal in pain you know it is in pain… it takes a lot of willful blindness not to acknowledge…"
  • "One of the reasons… why animals could not possibly feel any pain… because it would then be far too horrible how we treat animals… god wouldn't allow it!"
  • "If we assume the world is good & we see all the apparent suffering… then it cannot be… A moral reason behind denying the suffering of animals"
  • JW "An echo of a religious mode of thought that's then re-built in a humanist mode of thought"
  • "If we have evolved naturally… there's no reason to assume our brains are capable of understanding the universe… what possible use can it have?"
  • "A naturalistic perspective should actually teach us humility"

29:03 What Matters?

  • "I don't think that my early Christian upbringing has shaped my morals ideas & values"
  • "Morally I've been shaped… mostly by watching certain TV shows like Lassie & The Waltons & Little House on The Prairie… taught me what it means to do something right & something wrong… People & animals being in certain relations with each other"
  • "Being nice to each other… being decent… qualities that do not play a major role in ethical discussions but I think they are foundational"
  • Vs. #nihilism, #divinecommandtheory, #relativism, #egoism, transactional…
  • "I find it very difficult to align myself with a particular ethical system… #utilitarian … #Kantian … whatever… those systems highlight different aspects… that are all important"
  • "It's a wrong approach to say 'if we have conflicting moral intuitions one of them must be false'"
  • "When philosophers try to tell you that there's one right answer… I'm always suspicious."
  • “To think that there must be a right answer somehow assumes that we can live a perfectly good life”
  • Writing “Biotechnology and the integrity of life” & dignity
  • Bernard Rollin and the challenges to utilitarianism: When suffering reduction seems wrong (e.g. genetically engineering chickens to suffer less in factory farms)
  • “There seems to be something wrong in creating a living being that isn’t able to feel anything” Would enslavement be OK if we created humans that couldn’t suffer – or enjoyed being enslaved?
  • “Integrity… a word you use in order to capture a certain intuition… perhaps in the hope that by giving an intuition a name it becomes more real”
  • Luna intervenes

45:35 Who Matters?

  • Reading Peter Singer’s “Animal Liberation” & going vegetarian “I didn’t want to participate in practices that caused so much animal suffering”
  • Later “I stopped being a vegetarian so I reverted to a morality, at least in practice, that was smaller, narrower in scope than what it used to be”
  • “I’m a bit reluctant to reconsider the theory just to match my behaviour… people’s theories are very much influenced by what they want to be true”
  • The hypocrisy of adapting theory to match behaviour vs. the hypocrisy of behaviour not matching theory
  • “Why did I stop? The cynical answer would be that I got tired of being good… it takes so much effort… socially… it became probably too inconvenient.”
  • “I still believe that, obviously, animals have moral status and that animal lives matters and that animal suffering matters”
  • “We cannot live without killing” (e.g. crop deaths)
  • “It is utopian to think we could all live peacefully together without hurting each other… that does not mean you cannot reduce the suffering that you cause… I don’t really have a justification for why I’m not doing that more than I’m currently doing”
  • Ivory tower vs. activist vs. ordinary people philosophers
  • Why moral philosophers don’t seem to behave better than other humans
  • Ethics, morality and meaning “Defending a subjectivist conception of meaning in life”
  • “I don’t think meaning is an objective quality of life… but rather it is an aspect of the experience”
  • Meaning doesn’t have to “serve a higher purpose… or connect to some objective values”
  • The problems of paradigmatic cases of meaningful lives… famous people like Mother Theresa, Gandhi, Picasso, Einstein… people who did important things
  • “If that is the paradigm that you use in order to understand what a meaningful life looks like – the result is that most lives look meaningless… it seems to me this is wrong.”
  • “Even thought it might not be important from the perspective of the world or of society… they might just live their lives… no one takes any notice of it… they will be completely forgotten… but that doesn’t mean they don’t live meaningful lives”
  • You don’t have to do “important things” to have a meaningful life
  • “Many people just live ordinary lives… that does not mean their lives are not meaningful… there are things in those lives that they follow with interest… that are important to them”
  • “Meaning being subjective… a quality of our experience”
  • “I just don’t get the notion of objective value”… things mattering to us is enough
  • “The very notion of objective value appears obscure to me… I don’t understand what it means to say that something is valuable if nobody values it!”
  • “Value that isn’t realised by anyone”?
  • “Things matter if they matter to someone”
  • Michael’s “Living Like A Dog” paper
  • William James’ “On a certain blindness in human beings” “We have to assume that there’s always more to the experience of someone that is different from ourselves than we can possibly understand… because the other is the other”
  • “It seems to me the same is the case with animals… it’s not even that difficult”
  • “Many philosophers… their theories clearly exclude animals from having meaningful lives… very anthropocentric… you have to do things like art or philosophy in order to have a meaningful life… not just eat and drink and sleep… what we share with other animals is not what makes our life meaningful… what goes beyond the animal… what surpasses the animal in us”
  • “To say that non-human animals do not have meaningful lives… we judge their lives as not worth living”
  • “In reality we very much associate a meaningless life with a life not worth living… or that has a very reduced value”
  • “A live that is meaningless… is not worth protecting… is not worth any moral consideration”
  • Michael’s dog companion “Whatever she does there is interest there… you can see that clearly her life… is meaningful for her in the sense of being significant”
  • “We have this idea that only human lives are truly worth living”
  • A transhumanist take on animal rights
  • Previous guest and co-founder of the World Transhumanist Association David Pearce
  • Human enhancement would “leave behind” non-human animals so “we also have an obligation to uplift animals to a human status and beyond… because the life of a non-human animal is ‘bad’ because it is the life of an animal… even the best animal life… is a bad life… they cannot do art, philosophy, politics…”
  • “For me that is so weird because it assumes that our lives are the best lives”
  • John Stuart Mill’s “Better to be an unhappy Socrates than an happy pig”… “what’s wrong with happy pigs?… for a pig to be a happy pig is the best you can ever be… It’s not the case that the pig would be better off if they were a human.”
  • The risks of transhumanist elitism even within the human species
  • Would re-engineering animals (human or not) so we cannot suffer be a good thing?
  • Eradicating or herbivorising predators?
  • “Again there is this unease about it… does the suffering also have a value?… what gets lost if we cannot suffer any more?”
  • “What happens to love?… If I cannot suffer when something bad happens to the one I love… I cannot suffer from the loss of the one I love… If I am indifferent… How can I say I love them?”
  • “If you remove suffering a lot of other things will also change… you cannot just isolate one thing and take it out… it will all be affected.”
  • “Even the word wrong seems wrong to me”… “Just because we cannot articulate it [what might be lost] with sufficient clarity doesn’t mean it isn’t there…”
  • The naturalistic fallacy: “I wouldn’t want to say that just because it’s natural it’s good but in natural things… there is horror… but there is also a lot of beauty… predators are beautiful too and that beauty should count for something”
  • Plotinus “beauty is the shine of the good”
  • “The beauty of the world is important… an indication of what is worth protecting”
  • Humility vs. “to think you can redesign the world… to create a world in which no one suffers… there’s no humility in there”
  • “Some who pursue those goals would deny precisely that [humility]”
  • John Harris: “Humility is not a virtue… you should be proud and ambitious”
  • “I don’t think there is an overall referee that could actually make the ultimate decision about who is right and who is wrong… it’s about us making certain decisions… creating the kind of world and also preserving the kind of world that we want to have”

01:26:44 How Can We Make a Better Future?

  • “My hope is somehow that we become more caring & less ideological & less self-destructive”
  • Politics: Brexit “and the willingness to commit economic suicide… the anti-immigration impulse”
  • “After 4 years of Trump being president more than 70 million Americans still want to have him again… should govern… one should emulate… the lack of decency”
  • “He’s the opposite of decency – he’s pure nastiness… that nastiness is not only being tolerated but admired and approved of… and he is just the tip of the iceberg”
  • Putin’s attack on Ukraine “It defies any reason”
  • “It’s not only that people are irrational… they seem to positively delight in destruction and chaos…"
  • “I’m a bit disillusioned… I assumed somehow that people are reasonable… to find a compromise… to get along with each other.”
  • “But the fact is we are a horrible species… we do things just for the sake of destruction and chaos”
  • “I only see it getting worse and worse – I’m quite pessimistic at the moment.”
  • JW “Philosophy can play an important role… but it can’t be disconnected… it has to be plugged into a realistic understanding of human psychology and social norms and political will”
