Peter Singer

83 books8,791 followers
Peter Singer is sometimes called "the world’s most influential living philosopher" although he thinks that if that is true, it doesn't say much for all the other living philosophers around today. He has also been called the father (or grandfather?) of the modern animal rights movement, even though he doesn't base his philosophical views on rights, either for humans or for animals.


In 2005 Time magazine named Singer one of the 100 most influential people in the world, and the Gottlieb Duttweiler Institute ranked him 3rd among Global Thought Leaders for 2013. (He has since slipped to 36th.) He is known especially for his work on the ethics of our treatment of animals, for his controversial critique of the sanctity of life doctrine in bioethics, and for his writings on the obligations of the affluent to aid those living in extreme poverty. 


Singer first became well-known internationally after the publication of Animal Liberation in 1975. In 2011 Time included Animal Liberation on its “All-TIME” list of the 100 best nonfiction books published in English since the magazine began, in 1923. Singer has written, co-authored, edited or co-edited more than 50 books, including Practical Ethics; The Expanding Circle; How Are We to Live?, Rethinking Life and Death, The Ethics of What We Eat (with Jim Mason), The Point of View of the Universe (with Katarzyna de Lazari-Radek), The Most Good You Can Do, Ethics in the Real World and Utilitarianism: A Very Short Introduction. His works have appeared in more than 30 languages.

Singer’s book The Life You Can Save, first published in 2009, led him to found a non-profit organization of the same name. In 2019, Singer got back the rights to the book and granted them to the organization, enabling it to make the eBook and audiobook versions available free from its website, www.thelifeyoucansave.org.



Peter Singer was born in Melbourne, Australia, in 1946, and educated at the University of Melbourne and the University of Oxford. After teaching in England, the United States and Australia, he has, since 1999, been Ira W. DeCamp Professor of Bioethics in the University Center for Human Values at Princeton University. He is married, with three daughters and four grandchildren. His recreations include hiking and surfing. In 2012 he was made a Companion of the Order of Australia, the nation’s highest civic honour.

I read this book in an Ethics class in college. I don't really remember much of it, at the time I was a vegetarian, I'd flirted unsuccessfully with being a vegan for about a month and a half at the start of the school year before tiring of every meal I ate being an ethical war between me and one of my roommates. I was very well versed in animal rights, I knew why I wasn't eating meat, and I remember this book not really adding anything I hadn't already wrestled with in my head.

During that class the four or five philosophy majors were chosen by the professor to debate each other on the ethical question of vegetarianism, none of the other 25 or 30 students had to do this debate thing, it was just us handful of nerds getting to argue with each other for 20 minutes in front of a sleepy and bored class. I don't know if I choose it or was told by the professor or what but I ended up having to defend eating meat. I went at this like any good philosophy student, with the realization that anything in the world can be proved, you can argue in favor of anything. I just needed to get some facts that would play in my favor (this is a tip for anyone in school who doesn't want to do 'research' decide what you want your outcome to be and then find supporting evidence, it's there, for just about anything you want to prove you can find enough to support you, if not you pick and choose carefully from what you can find. This technique generally works quite well). I tried my hardest to find some slam dunk arguments for why eating meat was ethically good. Surprisingly, (or not), I couldn't find anything in my college library that made any kind of sense. Here are the arguments I came up with (and I took out all the books, copied the articles and brought them all to class, because I knew there was no way anyone was going to believe some of this shit).
1) The economy. Lots of jobs would be lost by everyone going vegetarian. Think of all the people who raise, kill, and pack your meat. Never mind the butchers!!!
2) The bible. Yes this was cited. God forbade us from eating meat, he let us eat meat, and then he gave us permission again after the whole flood fiasco. Kind of like, we saved you now we get to eat your babies.
3) Humans are supposed to eat meat. Actually no, but I found some scholarly source saying this, so I used it in the argument.
4) It just tastes good. (I don't know how this is ethical, but except for number 1, it's the only argument that has any real sense to it).
and number 5) this is the kicker, my slam dunk, the one I opened up the book I found this argument in, and read it straight from the book, because there was no way in hell anyone would have believed me on this (you will have to take my word on this).... because if we stopped eating meat the countryside of England and other European countries would become overgrown and not as picturesque as it is now, because grazing animals keep everything so nice as it is.

My side lost the debate, and at one point I was yelled at by the guitar player in my band (who was on the other side) that I couldn't say that animals tasted good because I was a vegetarian, which I answered that no, I'm for eating meat in this debate, something that he seemed to have a hard time wrapping his head around. I don't know how he faired in his philosophy career, but anyway....

The point of this story is that I had a really hard time to come up with any ethical reason why eating animals is good, or permissible. Maybe I missed something, but at the time I think I tried pretty damn hard to find a good argument to use, and even now that I eat animals again, I only do it by not thinking about it, kind of like being in constant denial or blind to what it really is. This is shitty of me, and it's yet another reason why I suck as a human being and make the world just that little bit worse by my being here....

This was a very difficult book to read because of the dozens of stories of factory farming and animal abuse. I have been vegetarian for thirty-seven years. This book makes me seriously consider veganism. Read it and become aware of how cruelly people treat fellow animals with feelings. My hope is that this book can and will change your own life for the better.

"The tragedy of the blue whale is in the reflection of an even greater one, that of man himself. What is the nature of a species that knowingly and without good reason exterminates another? When will man learn that he is but one form of life among countless thousands, each of which is in some way related to and dependent on all others? How long will man persist in the belief that he is the master of the Earth rather than one of its guests?" -p.130

"...Some zoos have been considering proposals to 'recycle' excess animals: a euphemism for killing them and feeding their bodies to other zoo animals. Many people are surprised when they hear of zoos killing animals. They should not be. Zoos have limited capacities. They want to maintain diverse collections. This can be done only by careful management of their 'stock'." -p.115

"Domestication itself is an unnatural process, a method of enslaving animals and subjecting their life processes to our will. Animal liberation would return domestic animals to their wild origins, free to pursue their destinies without human interference." -p. 72

"Once we have accepted that we may utilize animals for so trivial a reason as our enjoyment of the taste of their flesh, it is easy to use them for any purpose which is equally frivolous, such as domesticating them as pets or confining them in zoos to amuse us, or for those which are more serious, such as using them in medical experiments that we believe will save human lives." -p.70

"Only 42 per cent of an animal's original weight becomes meat." -p.68

"Mahatma Gandhi expressed this very clearly in The Moral Basis of Vegetarianism, edited by R. P. Prabhu. He commented, 'I do feel that spiritual progress does demand at some stage that we should cease to kill our fellow creatures for the satisfaction of our bodily wants'." -p.67

"Whatever their level of awareness, it remains true that people eat meat because they are accustomed to its colour, shape, texture and flavour, and have been conditioned to regard it as highly desirable food. Their attitudes must be challenged, and changed. As Peter Singer has pointed out in Animal Liberation, 'Those who, by their purchases, require animals to be killed have no right to be shielded from this or any other aspect of the production of the meat they buy. If it is distasteful for humans to think about, what can it be like for the animals to experience it?'" -p.69

Very deep and thought provoking book on the way we view and treat animals. Being a vegan myself I found this book fascinating and troubling at the same time. A very good read and good for the soul.

A constructive reminder for any ethical vegan.

Peter Singer chose his co-authors well in this collection. They all share his penchant for direct and coherent argumentation written plainly. The no-bullshit approach that seems effortless but must be anything but. It perhaps helps their argumentation that, or so I believe, what they are arguing for is so self-evidently correct if you give it just a bit of actual critical thought. Of course, the danger when you believe something is deeply wrong but obvious to see is that you become blinkered yourself, blinded by indignant fury. Such righteous fury is very human but not constructive. As is the case with most of Singer's work, my deep respect comes from his ability to remain logical and level-headed while still advocating for the moral good.

This ability is most present in the the third section of the book. A sobering and sorely needed reminder on what actual effective activism entails. This book is mostly for those already initiated into the cause and being part of a movement always brings the danger of slipping into an extremist view, or at the very least losing sight of what is most important. I came away from those last essays with a renewed sense, a feeling of being clear-eyed in what are the actual correct ways to act and think around the topic. For that, I am grateful.

Key takeaways

- The West has had a view of animal capability for suffering, of their worth, that has gone full circle from Pythagorean compassion to Christian slavery to Cartesian automata and back again to compassion.

- Factory farming is a horror show. Of course I already knew that but being given detailed descriptions always gives a renewed "appreciation" for the magnitude of the horror.

- Activism demands much of the activist. In order to be effective, you have to be pragmatic, consistent and systematic in your approach. Use cognitive empathy and meet people where they are. Being right is very rarely enough.

Thought-provoking and detailed. This book covers several areas of animal rights, from eating meat to zoos to testing on animals, and each is as heart-breaking as the next. It starts out with more philosophical and historical attitudes about animals, which I was less interested in, but then moved on to essays about the harmful impacts of various practices, like battery farming, then finally explores activism.
This book is fairly old now, so a lot of the information is outdated and potentially inaccurate (especially regarding laws around certain practices, as well as statistics) but the main sentiment is the same.
I was especially interested in the following chapters, although they were also the most graphic and shocking to read:
- Chapter 7: Brave new farm?
- Chapter 8: Outlawed in Europe
- Chapter 9: Against Zoos
- Chapter 11: How Austria achieved a historic breakthrough for animals

I also noted down this quote because it really summed up the chapter and the idea of the book:
'The minister felt that as a vegan I was not in a position to debate animal husbandry, to which I replied that only vegans can truly talk on behalf of animals, as they are the only ones without any personal interest in using animals.'

If you eat meat/eat eggs/visit zoos/wear fur/buy products which are tested on animals, this book will most likely make you reconsider some of your choices. And as it says in one of the chapters, we don't all have to be perfect in every way, so if becoming vegetarian seems impossible, even just trying to reduce your meat intake will be beneficial. After reading this book, I imagine most meat-eaters won't eat meat for a while.

A brilliant collection of essays and constantly refreshing insight from a multitude of perspectives. The third section of this book - activists and their strategies - was surprisingly interesting and informative, containing useful insight into effective advocacy and opposition, whilst simultaneously reinforcing the ethical position (as established in section one - the ideas) and exemplifying standard practice (as outlined in section two - the problems).

Essays of particular interest include ones on utilitarianism, personhood and effective activism - all of which I have learned a great deal from and encourage anyone interested in animal ethics to do so aswell.

In defense of animals is a collection of essays written by different authors, highlighting different aspects of compassion and animal defense. It is divided in three parts: The ideas (why animals should not be harmed), The problems (why laboratory testing, industrial farming, zoos and eating animals are wrong), and The activists and their strategies (how to achieve the goals of changing legislation in favor of animals, how to have prosperous businesses without hurting animals, and how to advocate in favor of animal rights).

I always enjoy these collections of essays from different authors, as they provide the reader with different perspectives and tools to address the challenges that those of us who care both about human and non-human animals face every day.

A recommended book, indeed!

The book Animal Defenses, is another great book in a great informational series, Wild Wild World. There may not be a story, but I still enjoyed it very much. If you are an animal person, this book is for you. The great description of the animals and their abilities got me lured in. There is lots of information, so you don’t feel like you’re reading a broken record.

Strangely, I could actually relate to some of the animals. The animal arsenal is unpredictable, and some animals are as introverted as me. I especially liked learning all the new information. The world of animals is always growing, and this gives me some incite on some of the most recent discoveries. It opens my mind to some inspiration, and maybe I can use some of the things I learned in life.

For those interested in our cousins in fur, feathers, and fins, this book is for you. Not only that, but some short stories written about animals are included in some parts of the book, for those who like stories. However, this book, like most things, are not perfect. I often lost my place, due to little side paragraphs, and pictures take up most of the pages, good thing these are big pages. Overall, the book Animal Defenses is a good informational book with interesting things to last for a long time, and I give it five starfish.

This is the most comprehensive book I've read on human relations with non-human animals. I've read a few books on factory farming, but here Singer also collects essays discussing arguments for and against zoos and animal testing. This section discussing real life issues involving our relationships with other animals comes after philosophical essays on the moral implications of our treatment of animals. I learned about speciesism, how our views on animals are shaped by different religions, and why some people eat or don't eat other primates in the essay "To Eat The Laughing Animal". The third and last section of the book includes inspiring stories from activists around the world, and even advice on how you can also be a positive and effective force in animal protection. I'll definitely be reading this again.

W książce tej znajdziemy rozważania nad pojęciem utylitaryzmu w kontekście zwierząt, rozłożenie na czynniki pierwsze pojęcia bólu i cierpienia czy też aspekty religijne i odwoływanie się w nich do zwierząt, co osobiście ciekawi mnie najbardziej. Biorąc pod uwagę zmieniające się warunki, technologie, książka ta na nowo buduje morale oraz poszukuje rozwiązań do zastałych czasów. Zwierzęta cierpią cały czas i choć udało się wiele na przestrzeni lat poprawić, to nadal zmierzamy się z nowymi technologiami i rosnącą konsumpcją. Spokojnie mogę polecić jako jedna z lepszych książek o zwierzętach.

Great book on the animal rights movement; edited by Peter Singer. A collection of essays from influential people within the movement on topics like factory farming, the idea of 'self', animal intelligence, the relation between activists and the media, etc. Really good introductory book, as the topics are dealt with in short segments, by a wide range of authors. Makes you think.............

An interesting compilation of essays on a variety of topics related to animal ethics and animal activism. I think it is definitely worthwhile reading, despite the information not being quite up to date. In fact, because of when it was published it gives a nice insight into the animal activism scene in the early 1980s.

Good introduction into the subjects and issues surrounding the way humans treat animals.

The books should be modernised (graphics, themes, content) if it is to appeal to a wider audience.
