As a vegetarian, when I consider the prospect of having a child I must ask myself whether to bring her up on the same diet as mine. I have met people who resentfully continue to be vegetarians because their parents brought them up that way and they could never ingest meat properly. Is it fair for parents to treat a child in this way and would you answer that question differently if the majority of adults, but not children, had freely chosen to be vegetarians and were now asking themselves the same question?

Hello My Veggie Friend, This is a question that also puzzles me. I am not sure if fairness is the central issue. Let's deal with the resentful vegetarians who continue with the program because they 'cannot ingest meat properly.' My understanding is that born-and-raise vegetarians can adapt to a meat diet. They will encounter some initial stomach upset, but this will go away in short order. From a nutritional point of view, someone raised vegetarian could make the switch. From a moral and psychological point of view, the change will be much more difficult. I don't know why you personally are a vegetarian. For me, I eventually became convinced when I read the classic article "Eating Meat and Eating People," by the fabulously smart Cora Diamond. I won't try to recount her views here precisely, but what I took away from the article was simply that people become committed to vegetarianism when their concepts of food no longer includes animals. I suspect the resentful vegetarians you describe...

In a hypothetical situation I am a vegan talking to a meat eater who buys his meat from a supermarket and has no interest in where it came from. I say that I don't think people have the right to eat meat unless they are willing to learn about what it takes to provide that meat, witness it first hand or even produce it for themselves. He says that he doesn't want to know where it came from and is quite happy for someone else to do the dirty work if they are happy to and does not feel at all guilty. Is he morally wrong and do I have a valid argument?

This is a neat situation because the meat eater is so unrepentant! It must be infuriating for the vegan. I fantasize the meat eater holds a juicy burger while the debate goes on. Precious! I think the philosophical question at heart has to do with ignorance. Is purposefully dwelling in ignorance morally acceptable? Notice this is not the same thing as Is purposefully dwelling in ignorance psychologically comfortable? We know the answer to that last question is yes. That's why the prisoners in Plato's Allegory of the Cave have to be dragged up to the sunlight. So on to is purposefully dwelling in ignorance morally acceptable. There are some instances in which I think we can say yes, ignorance is acceptable. For example, I have heard it said that the famous philosopher Peter Singer (who advances the view that most Westerners should donate all excess funds to the world's poor) can't play football/soccer and think about the poor at the same time. Say this story is true: he purposefully...

Is it animal abuse to spay/neuter an animal? Most people justify spay/neutering by pointing out that if we sterilize animals, there will be fewer needier animals. But if that's true, why not forcibly sterilize people in third world countries (at least in areas with population problems)?

I think the basic reason why it is acceptable to sterilize non-human animals and not impoverished people is that animals do not have reproductive rights, but people do. I think it is a fundamental human right to have choices regarding when to have children, with whom to have them, and how many to have. Being very poor does not weaken one's claim on human rights. (Even people who philosophically or religiously object to contraception believe in reproductive rights to a limited extent. They believe they have the right to let nature or God make the reproductive choices for them.) Animals, on the other hand, have no reproductive rights. This may seem odd, given the recent progress in animal rights. I am sure there are animal right activists who believe that pets ought to reproduce without human intervention, but this must be a small minority. Most mainstream animal rights groups urge sterilization to benefit animal welfare.
