A few days ago I posted about the differences between deontological and consequentialist views in ethics. Consequentialists think consequences are all that matters in terms of evaluating the moral status of an action. Deontologists think other factors can sometimes trump consequences, and thus you'll end up with situations when doing the right thing requires doing something that doesn't lead to the best consequences.
My main point in the post was to defend a moderate deontological position in one respect. Absolutists think the moral principles that are more important than consequences are always more important than the consequences. In other words, absolutists hold that deontological moral principles always apply, and consequences are irrelevant. A moderate deontologist in this respect will argue that deontological principles are not always absolute in that sense. Sometimes consequences will be so much more important that the principle doesn't truimp the consequences in that case. These deontological principles will then have a threshold. If the consequences are serious enough that they surpass the threshold, then the principle no longer holds for that action. If they are below that threshold, then they hold.
An example of how this works comes from Plato. It's usually wrong to steal, and if you borrow something it's usually immoral to refuse to return it. But what if you borrow your friend's sword, and your friend returns to you asking for the sword after you've discovered that your friend intends to use it to commit a great evil? Plato argues that it would be wrong to return the sword, even though normally you ought to do so. The moderate deontologist explains this in terms of this particular action being above the threshold for the immorality of stealing (or more precisely of refusing to return borrowed possesions).
In the rest of this post, I'd like to apply this line of thought to the first case I presented at the outset of my previous post. I want to say that in those cases a deontologist can say what I want to say without being a consequentialist. The first case was a pro-life voter who shudders at pulling the lever for someone as pro-choice as Rudy Giuliani, even if the consequence of pro-lifers taking such an attitude is that the even more pro-choice Hillary Clinton would be guaranteed to become the next president. Two things matter here. One is that Rudy Giuliani really is preferable to Hillary Clinton according to pro-life criteria, even if both are much closer to the not preferred end of the spectrum. The second is that the moral principles at stake here are not absolutes, and in certain situations above the threshold the principles no longer apply.
As a fiscal conservative with federalist tendencies, Giuliani doesn't think the federal government is the place to further such an agenda. He didn't even further it at the local level when he was mayor of New York City. He simply retained the status quo. Hillary Clinton would much more militantly pursue a pro-choice regime.
