I am thoroughly confused by the ethics of vegetarianism, which to my mind seems more of a religious objection towards eating meat than a scientific point of view. Recently I attended a lecture by Peter Singer ( Animal Liberation ) on the ethics of eating meat. One thing he did not address was differentiating between the 'killing' of the (sentient) animal and the 'eating' of it. OK- so here is my question: is it ethical to eat roadkill, or animals that have died of "natural" causes or of "old age"? Further to this, is being killed by a human primate not a "natural" cause of death of a cow? If humans shouldn't kill cows to eat (because we know better), perhaps we could let lions kill the cows, then we can eat them afterwards? Isn't it unethical to tell people in the developing world they shouldn't eat meat? - especially when a huge percentage of women in the developing world are iron deficient? Thanks, Grant M.

There are at least three different kinds of argument in favor of vegetarianism, and each of the arguments have slightly different implications for what is OK. One argument is concerned with human health (so is more prudential than moral). The idea is that eating dead animals is not healthy for humans, or at least a balanced vegetarian diet is more healthy. This view is not really compatible with eating roadkill, but would be compatible with eating meat if there was insufficient vegetarian food to keep one healthy. Another argument is concerned with the environment. The idea is that factory farming wastes precious resources (like water) and is inefficient in producing the nutrients humans need. (For details, see "Environmental vegetarianism" in Wikipedia.) This argument also doesn't preclude killing or eating animals where the practices used to raise them are environmentally sound (but it can be developed into a case for a qualified veganism, given the parallel concerns about the...

Is there anything existing within or beyond the human body or mind that can be called I? If so, exactly where is I located?

Who is going to be calling this thing "I"? Are you asking whether you could be something other than a human body or mind? Let's suppose so, and let's suppose you are a person now embodied in a human body. It is tempting, I think, to say that when you use the term 'I' you are simply referring to the living human body who is you. Your ID gives your height, weight, eye color, etc. because that human body is who you are. However, some thought experiments (and films, tv, and novels) suggest that you could exist in a non-human body, e.g., Kavka suggests in Metamorphosis that Gregory could become a cockroach. It is common in popular culture these days to find persons taking on the bodies of dogs. So it seems that our concept of person allows that you aren't just that human body. (Though this isn't the end of the discussion about human bodies, because our fictional narratives of humans taking on other forms may be based on false beliefs about the relationship between minds and bodies.) ...

How do philosophers decide where to draw a distinction between what one "has" and what one "is". That is to say, am I the same "I" that existed before I lost a toe, or a leg, or the rest of my body, or even my brain, my mind, my thoughts, my self? Is it not logical to say that what is "me" must be distinct from what is "mine"? If this is not true, then would not "I" exist only in a virtual sense, as the image or focus of all "my" possessions?

This is a good quesiton and one that philosophers disagree about. There are three sets of issues to consider. One is how to make sense of the persistence of anything through any change whatsoever. For example, if a tomato ripens and turns from green to red, is it the green tomato the same tomato as the red one? How can that be if one and the same thing cannot be both red and not-red? Are there some properties of an object that can alter without destroying the object, and others not? How can we make sense of that? The second set concerns change of parts. Consider a statue and a lump of clay. It seems that the statue just is the lump of clay shaped in a certain way. But if the statue loses an arm, it seems that it is still the same statue, but it isn't the same lump of clay. Or suppose we replace the arm with one molded into the same shape out of different clay. Again, it seems that the statue can survive such a change, but the lump of clay that is the statue is not the same as the...

Socrates said "It is better to suffer evil than to do it". I am trying to work out if a consequentialist could make good sense of this claim, if anyone can!

From Socrates' point of view, doing wrong harms the soul. Since on his view the soul is the most valuable thing there is, it is important to protect the soul from this harm. Suffering evil, in contrast, doesn't harm the soul. It might harm the body. It might be psychologically difficult. But it doesn't harm the most valuable thing. So doing evil is worse than suffering it. Is it possible to make sense of this without accepting that there is a soul? You might think that there are different sorts of value: aesthetic value, moral value, individual well-being, etc. You might also think that some of these can "trump" others. So, for example, occasionally I am required to sacrifice some amount of well-being in order to do what is right. There may also be times when I must suffer at the hands of others in order to do what is right. When there is a conflict, fulfilling one's moral obligations is more important than achieving individual well-being. But this comes close to what Socrates was...
