"Well, that's more or less my point. I am saying the cow does not have an express interest in living. When I speak about a "biological" disposition, I am speaking about an inherited behaviour to avoid damage. Animals, indeed all organisms (including plants) have evolved defences against damage. There is no actual intent here, it is a blind evolutionary outcome. A cow's desire to live on is not really such, it is the evolutionary imperative of reproducing successfully. Just like a potato plant. Humans on the other hand have the abstract idea that they can die, so our interest in living on is an express one (as well as the underlying biological disposition).
Cow's also have a desire to avoid harm, as do we. Again, it's largely an evolved defence but it IS accompanied by painful feelings so for both us and the cow there is an actual desire or interest. If a cow could speak, it couldn't say that it doesn't want to die, but it could say it doesn't want to be hurt. I would suggest that we can farm cows in such a way as not to cause them harm, day to day (ie, pain and suffering)."
So first of all, I’d like to know how you think you know what a cow would or could say if a cow could speak?
What we do know, based on the studies of animal behaviorists, psychologists, neurologists, etc etc. is that animals show the same or at least very similar reactions in the face of danger as humans do. Plants do not. Since plants don’t have brains, the suggestion that animal reactions to danger were similar to plant reactions is just kinda ludicrous on the face of it. But that aside, we have a preponderance of evidence that animals do feel as we do in the face of danger, and a total lack of evidence that they are missing something.
"In regards to the difference between the interests of a non-imapired human and an impaired or immature human, the reason for that moral duty is nothing to do with the biological interests of the person, but rather some broader species-specific interest. Put another way, in our society we are of the view that babies and impaired persons attract the right to life merely because they are human. In other times and places, that moral duty may not apply (for example, utilitarians may believe there is a strong case for euthanising persons with severe disability)."
Utilitarians only believe there is a strong case for euthanizing disabled persons who are acutely suffering, actually. And they do not advocate for it on the basis of species-bonds, but on the individual’s experiences and out of concern that the life of such a person is less pleasurable than painful.
In this context, we have come to see other humans as deserving of rights that trump any interest we might have in depriving them of life (eg it is murder to kill your severely impaired daughter). But this may merely be a matter of convention, subject to change in the future. It would only remain so if we believe that the course of ethics is to improve our beliefs and behaviours. I'm not sure that an evolutionary/historical account would bear that out.
"On the other hand, our interests in using other animals for life sustaining purposes of ours may still trump their interests in avoiding harm (again, I am of the view that if we don't harm them day to day, then there is no interest we have quashed by using them to our ends). The real question is how much harm we agree is acceptable to cause them. Vegans would ask that we harm them not at all."
We’re not killing animals to sustain our own lives. We’re doing so to enhance the pleasure of our own lives. Big difference.
"I'm not quite sure of your argument here. Yes, of course, feeling pain when being killed is a harm. If the steer, you or me can be killed without pain, then we have not been harmed in that sense. However, there is a broader sense in which death is not a harm. Harms accrue to living beings. Once dead, you do not exist and cannot be harmed. So, if in killing you I cause you no pain, you are not harmed. And once dead, no harm can accrue. So there is no harm in killing someone painlessly, at least not to them."
Is that going to be your plea to the judge when convicted of murdering and eating your neighbor?
"The best we can say is that death thwarts our future potential but I consider that an uncertain claim for the reason that we cannot say what that potential is. It may be that if I don't kill you today, you will die from a heart attack tomorrow. Of course, your death will cause harm (suffering) to those that love you or have some close personal relationship with you, so we do consider that of relevance in the human case. I am not convinced that is such an issue with other animals. It seems to be with elephants, for example, but I'm not sure it is with cattle. It's probably an open question whether a typical herd suffers from the loss of any of their number. I believe The Last Pig does, if the movie of the same name is any guide."
“How Animals Grieve” by Barbara King is an excellent resource on the matter. There are numerous other books and accounts that describe the grief herd animals go through when one of their own, especially their offspring, are taken or killed.
"If we eradicated factory farms and the evils that go with it, the vast majority of people would still have to go vegan because there simply would not be enough meat to go around.— Artemis
I completely disagree. How could you possibly come to that conclusion?"
You can disagree as completely or incompletely as you like, but that doesn’t change the fact that our current meat-consumption habits are dependent on the mass-production only a factory farm can afford. 99% of our meat comes from the factories. We don’t have the farm land or labor force necessary to sustain both the pastoral ideal and our overconsumption.
"Also, people like to suggest that "nature is red in tooth and claw," but if you look at the average day-in-the-life of a wild animal--especially a large, herding herbivore like a cow-- it is (or would be) pretty pleasant.— Artemis
I think that claim is subject to scrutiny. I suspect that on average, a wild animal's life is quite stressful and filled with suffering. In fact, I suspect that the vast majority of those born do not make it to sexual maturity which must bias the odds in favour of suffering outweighing happiness. It's worth considering the fact that in everyday terms, we cannot do much to alleviate the suffering of wild animals. The farmer on the other hand, can do a great deal to alleviate the suffering of farmed animals. On balance, it should be the case that a farmed animal subjected to ethical methods should experience more happiness and far less suffering than a wild animal."
You suspect it is stressful, but again, you’re just throwing claims out there in the hopes that they might be true or true enough to make your case.
Grazing herd animals when found in the wild are not constantly being picked off and eaten. They do not reproduce quickly enough for that to be the case. Animals like mosquitoes get picked off by the hundreds before they lay eggs—which is why they lay hundreds of eggs. But even if it were true that animals get eaten in the wild too… I mean that just suggests their life in the wild might be as bad as being in captivity and doomed to the slaughterhouse. That certainly doesn’t justify the act of killing on the part of any moral agent.
But again, even if you were right about all that, you still come back to a moral theory which suggests “I did you a good, now I’m allowed to do you a bad” which is just obviously and completely bankrupt—especially a system in which you are allowed to force the good and then therefore the bad on unwilling or at least non-consenting participants.
