Not true! Utilitarianism is a relatively straightforward one to evaluate -- do whatever causes the least suffering (or the most pleasure, or the most happiness, etc). A utilitarian might say that the foetus suffers (or experiences pleasure, happiness, etc) to a much lesser degree than the mother, therefore the mother's wishes triumph over the foetus'. If the dad's wishes are involved, a utilitarian might argue that a the right to self-determination (i.e. the ability to do as one wishes with one's own body) gives the most overall (societal) <insert metric here>, and therefore the mother's wishes triumph over all others'.I agree. But I don't think there is a system which is able to deal with the whole spectrum of circumstances which tag along with the abortion scenario. Rape, threat to the mother's health, etc.
Other moral systems might introduce concepts such as responsibility; in the case of rape, the mother was not responsible for the pregnancy, and so is not responsible for the child, but outside of rape, abortion may still be morally wrong (or right) by some other part of the moral system.
A christian, for example, might say that it's okay to attempt to abort the foetus in a way that doesn't make the death of the foetus a necessary result, but a side effect, of saving the mothers' life (for the same reason it's okay to kill in self-defence, or kill 1 man to save 6 in some circumstances -- see the [wiki]doctrine of double effect[/wiki]). I'm not a christian ethicist though -- I just don't know enough about it. I might even be talking nonsense here, so maybe ask Plotinus what they really think

Well, this is all very well and good, but none of it actually helps answer the problem. The problem being: when is it morally right/permissible to abort the foetus? All you're telling me is what to consider -- I must consider whether the foetus is capable of experiencing pain, I must consider whether the mother was raped, I must consider whether the mother wants an abortion, I must consider whether the mother's life is threatened... But it doesn't tell me what I'm supposed to do with all these considerations! Utilitarianism tells me to look at all of these things too -- but it also tells me what to do with them: It tells me I should weigh up the suffering (or happiness, or whatever metric this particular brand of utilitarianism tries to min-max), and pick the one that causes the least (or most). Of course, endless debates can go on in considering how much suffering is actually involved, but at least, once I've done all that considering, I know how to act. Less "fuzzy", more "binary" systems that involve more specific sets of rules or principles similarly tell me what to do, given certain inputs; the system might be completely indifferent to one or more of the inputs you described above (a Catholic's ethics might be blind to the mother's wishes, as you recognised), but it is still capable of giving a moral prescription.The GR doesn't explicitly state my moral look at abortion, but it does give some pointers. For instance, I don't like pain. It would be immoral for me to inflict pain. When the foetus is in the stage it can't feel pain the GR doesn't help me much, in the stage where it has developed a CC, it does, and at that point for me the status of the foetus changes.
I don't like putting people in harms way. This is more complicated. If we're at the stage that the foetus does not feel pain, and the live of the mother is threatened, it's clear to me. In case the foetus has developed a CC, it becomes a matter of weighing two evils against each other. What if the mother will almost certainly die?
In these cases I am rather pleased not to subscribe to a system which is absolute in it's verdict. Because such systems completely disregard the many circumstances and varying situations such a moral dilemma is surrounded with.
I think it does. The GR as I see it is being empathic with all those involved, not saying to yourself, "I would want this, thus the mother would want this", rather "what if I were the mother, what would I want?", but even that is not applicable when the mother is available to tell me what she wants. In that case it becomes "As the mother, I would want my opinion to be heard"
edit 3: I also think this kills the masochist objection which was raised. A masochist would have to reason form the perspective: "what if I weren't a masochist?"
No, it can to a certain extent, yes it can't handle every single thing. It's rather hard for me to be empathic towards a foetus since it's rather hard to learn what it wants.
And again, I don't see GR as a system which will deliver a system with nice clear morality rules, it's rather a system which motivates you to try to be empathic with others. And making decisions with that empathy in mind if that makes any sense.
The point is, the GR doesn't tell me how to act here. It might give me hints; it might smile suggestively at me from across the bar, but it's not going to take my clothes off and throw me onto the bed of moral prescription. You say you don't like absolutes, but what I am terrified of is unprincipled people going round making moral decisions based not on rational thought but on mere whim and gut feeling. It's especially scary when those people are Supreme Court judges, in charge of the armed forces, or members of my country's legislature. I don't really care whether you're a utilitarian or a kantian or a whateverelseian -- what matters is that there is some intellectually rigorous method of analysis for moral situations, so that we're not all at the mercy of our petty emotions. The GR simply doesn't provide one for all but the most trivial of cases.
