Brief intro to Singer on speciesism

Following on from my post on Scruton below - this may answer some of your points and questions...

Each year about five billion animals are slaughtered in the United States. They are killed to satisfy the American taste for their flesh. The vast majority of us consider this sort of treatment of other species morally acceptable (or at least nor particularly unacceptable). But is it?

After all, we know, do we not, that animals suffer? They are also, to differing degrees, capable of enjoying pleasurable experiences as well. Why then are we morally permitted to treat the members of other species so very differently to our own?

Singer’s challenge

In his 1975 book Animal Liberation, Peter Singer presents us with precisely this challenge: to morally justify the way in which we discriminate between our own species and others. His conclusion, shocking to many, is that this discrimination cannot, in fact, be morally justified. Indeed, Singer believes that the vast majority of human beings are currently guilty of what Singer terms “speciesism” (an expression first coined by Richard Ryder) – a form of bigotry against other species comparable to sexism and racism.

Of course, no one has ever suggested we shouldn’t be able to discriminate between conscious beings, or that we are not often morally justified in doing so. For example, we discriminate between children and adults. We give adults the right to vote, to drive, and live their lives more or less as they see fit, while withholding all these rights from children. But this discrimination is morally justified. Children are not yet mature enough to be able to exercise the right to vote responsibly or to drive a vehicle safely. Here is a difference that does indeed morally justify our discriminating in the way we do.

On the other hand, withholding the right to vote on the grounds of sex and skin colour is morally unjustified. Sex and skin colour are irrelevant when it comes to the ability to exercise the right to vote. Refusing such rights to women and non-whites therefore constitutes a form of bigotry. Were we to deny the vote on the basis of sex and skin colour, we would be guilty of sexism and racism.

So the difficulty the vast majority of us face, if we are not to find ourselves guilty of a similar form of bigotry, is to justify the way in which we discriminate between humans and other species.

Mental sophistication

Perhaps the most obvious suggestion to make is to point out that humans are far more mentally sophisticated than other species. We are more intelligent than they. We possess a shared language. We have a sense of right and wrong. And so on. Don’t these differences between humans on the one hand and cows, pigs, apes and sheep on the other justify the difference in treatment?

Singer doesn’t deny that our superior mental powers can, under certain circumstances, be morally relevant. Suppose we want to test a product on live subjects in a way that causes great pain and possibly death. One option would be to kidnap adult human beings from a local park and test it on them. Another would be to use animals instead.

Singer points out that testing on kidnapped humans might well result in greater suffering than testing on animals. If we start abducting and experiment on some humans, those that remain will soon figure out the danger and anticipate that they too may be kidnapped if they go out for a walk. Far more stress and anxiety may be caused than if we simply test on animals, who are too dim to experience any such anticipatory fear. In this case, perhaps we can make a slightly better case (if not a good case) for testing on animals than we can for testing on humans.

But, as Singer points out, sometimes our superior intellect means that we will suffer rather less than would an animal subjected to similar treatment. We can explain to prisoners of war that they will eventually be safely released, whereas wild animals incarcerated for a similar period of time cannot be given that knowledge, and so may suffer rather more than similarly incarcerated humans.

The mentally impaired

Perhaps the most obvious difficulty with the appeal to mental sophistication to justify the way in which we discriminate against other species is that some humans are no more mentally sophisticated than are some animals. Human babies, in fact, are far less cerebral than are mature primates. And of course there are many unfortunate mature humans who, either through and accident of birth or subsequent disease or damage, are no smarter or more mentally sophisticated than is the average ape. If certain forms of mental sophistication are our criteria for determining who is deserving of full moral consideration and who is not, then the boundary between those who are deserving and those who are undeserving will not coincide with the boundary between our species and others. It seems that we will have to say that, if it is morally acceptable to experiment upon or kill for meat the smarter animals, then it is morally acceptable to treat babies and the mentally impaired in a similar way. Or, if we continue to insist it is morally wrong to treat the less cerebral humans in this way, then we will have to say that it’s equally wrong to treat the smarter animals in that way too. What we cannot consistently do is draw the boundary between those deserving our full moral concern and those who do not where it is currently drawn – along the boundary between the human species and the rest.

A new attitude towards other species?

Singer’s own view is that we can quite rightly morally discriminate between sentient beings. He agrees it would be more wrong to kill a normal adult human being than it would be to kill, say, a mouse (in Practical Ethics, Singer suggests this is because a human, being a self-conscious being, can, and typically does, have a preference to go on living, whereas a mouse can have no such preference).

However, Singer argues that there is no moral justification for the way in which we currently discriminate. Discriminating solely on the basis of species is no more justified than was our earlier discrimination on the basis of sex and race. So far as justifying our current practices is concerned, whether or not sentient beings have feathers or fur, a beak or teeth, two legs or four, is simply irrelevant - as irrelevant as skin colour or sex.

When we now look back a few hundred years to how white people discriminated against black, and men discriminated against women, many of us are shocked. With hindsight, it can be difficult to understand how those who were engaged in these practices were unable to recognise that what they were doing was wrong. “How could they not see?” we ask.

The day may come when the human race looks back on the way we currently treat other species – raising and slaughtering five billion a year, in many cases under the most horrific conditions, simply to satisfy our taste for their flesh – and ask that same question. If that day comes, it will in large measure be Peter Singer’s legacy.

How not to avoid the charge of speciesism

Peter Singer has many critics. Many criticisms focus on Singer’s utilitarianism. For an overview of some of the main criticism of utilitarianism, see the chapters on Mill (chpt XX) and Bentham (chpt XX). However, even if we reject utilitarianism, the challenge Singer sets us – to point to the morally relevant difference between humans and other species that justifies our current discriminatory practices – remains. If we cannot meet that challenge, it is difficult to see how we can avoid the charge of speciesism, whether or not we’re utilitarians.

Unfortunately, many people are under the misapprehension that if they can come up with some cogent objection to utilitarianism, that is enough to fend off Singer’s charge of bigotry. That is not the case.

I don't think this does answer my question in the other thread. I think these answers begin to follow from the answers to the question why should we recognise the equal rights of all humans.

Singer famously doesn't recognise the equal rights of all humans, and many consider him a monster because of this.

And I suggest that an attitude that doesn't distinguish much morally between one's servants, wives and horses is actually nothing new, it has been practised for millennia. Spreading rights this thin necessarily diminishes them.

What justification does Singer give for suggesting species-ism is analogous to racism or sexism?

fridgemonkey - Singer's justification is that discrimination on the grounds of quality X is wrong where quality X is irrelevant to the matter being discriminated (so, for example, discriminating between carpenters on the grounds that one of them is a better carpenter than the other is fine, discriminating on the grounds that one of them is a woman is not). Singer's contention is that the qualities we choose when considering the treatment of others (suffering pain, consciousness, having foresight, or whatever) are not confined to one species, so saying that animal suffering (for example) is less important than human suffering is introducing an irrelevance (species) into consideration of suffering.

What's wrong with accepting that in many cases, people ARE speciesist: they disregard the moral interests of animals for no other reason than that they have long been accustomed to presuming that animals may be treated in nearly any fashion without moral scruple. But this need not imply that a non-speciesist must always find that animals may never be killed, eaten, etc. Perhaps there might be morally sufficient justification in some or even many cases for such uses of animals. But good reasons need to be offered in support of such a perspective. I think one problem is that many people want to find something wrong with Singer's viewpoints so that they can dismiss further consideration of the ethics of dealing with animals and hold that there is simply no serious problem to be confronted.

Let's put this another way. Equal rights for humans is in some sense equivalent to a universal duty not to discriminate between humans.

However, I don't see any point in a universal duty not to discriminate between granite and sandstone, or between cabbages and cauliflowers, or between rabbits and whippets. In each case I don't see why I should have to justify arbitrary favouritism.

So what is it that elevates an entity to the club where equal treatment matters?

A non-moral speciesism exists naturally in a natural animal food chain. Since consciousness and morality arrived late on the scene in humans it is excusable that humans have followed this natural order of speciesism in exploiting the food chain.

So, here we are now, still trying to make our cultural and genetic inheritance fit our modern view of species. But we're not as advanced as we'd like to think. How quickly would we revert to survival methods that take full advantage of any food available, if we had to? Even if we could prevent a return to some of the undesirable and cruel culturally driven practices of the past, could we deny our genetic makeup? We'd still eat meat.

"A new attitude towards other species?", "The day may come when the human race looks back on the way we currently treat other species ..." - Don't hold your breath. Some form of speciesism is here to stay for the foreseeable future.

Probably the best we can expect is legislating against unnecessary animal cruelty, and minimising animal suffering in the processing of food for humans.

The moral justifaction then for discrimination in the food chain is that it is evolutionarily natural for humans to eat other species. A mutual respect and feeling for sentience and suffering in other species may govern which species we eat and how we kill them.

EVIDENCE, MIRACLES AND THE EXISTENCE OF JESUS

(Published in Faith and Philosophy 2011. Volume 28, Issue 2, April 2011. Stephen Law. Pages 129-151) EVIDENCE, MIRACLES AND THE EXISTENCE OF JESUS Stephen Law Abstract The vast majority of Biblical historians believe there is evidence sufficient to place Jesus’ existence beyond reasonable doubt. Many believe the New Testament documents alone suffice firmly to establish Jesus as an actual, historical figure. I question these views. In particular, I argue (i) that the three most popular criteria by which various non-miraculous New Testament claims made about Jesus are supposedly corroborated are not sufficient, either singly or jointly, to place his existence beyond reasonable doubt, and (ii) that a prima facie plausible principle concerning how evidence should be assessed – a principle I call the contamination principle – entails that, given the large proportion of uncorroborated miracle claims made about Jesus in the New Testament documents, we should, in the absence of indepen

What is Humanism?

What is Humanism? “Humanism” is a word that has had and continues to have a number of meanings. The focus here is on kind of atheistic world-view espoused by those who organize and campaign under that banner in the UK and abroad. We should acknowledge that there remain other uses of term. In one of the loosest senses of the expression, a “Humanist” is someone whose world-view gives special importance to human concerns, values and dignity. If that is what a Humanist is, then of course most of us qualify as Humanists, including many religious theists. But the fact remains that, around the world, those who organize under the label “Humanism” tend to sign up to a narrower, atheistic view. What does Humanism, understood in this narrower way, involve? The boundaries of the concept remain somewhat vague and ambiguous. However, most of those who organize under the banner of Humanism would accept the following minimal seven-point characterization of their world-view.

Plantinga's Evolutionary Argument Against Naturalism refuted

Here's my central criticism of Plantinga's Evolutionary Argument Against Naturalism (EAAN). It's novel and was published in Analysis last year. Here's the gist. Plantinga argues that if naturalism and evolution are true, then semantic epiphenomenalism is very probably true - that's to say, the content of our beliefs does not causally impinge on our behaviour. And if semantic properties such as having such-and-such content or being true cannot causally impinge on behaviour, then they cannot be selected for by unguided evolution. Plantinga's argument requires, crucially, that there be no conceptual links between belief content and behaviour of a sort that it's actually very plausible to suppose exist (note that to suppose there are such conceptual links is not necessarily to suppose that content can be exhaustively captured in terms of behaviour or functional role, etc. in the way logical behaviourists or functionalists suppose). It turns o
