And of people being caught. Chances are that you will be caught eventually, and you would have to worry about it all the time.
Why assume this?
Wow, the facts keep changing here. I don't agree that desire is morally relevant, and you still have all the issues I named.
But then we've moved away from the terms set out in the OP, namely a consequentialist understanding of ethics. What's wrong with the tryst is not that it causes harm. It doesn't. Rather, it's wrong on other grounds. Perhaps I'm flouting a
sui generis duty. Perhaps I'm being disobedient to a divine command. Perhaps I am acting against a universalizable moral imperative. But in those cases, the harm isn't the issue, it's the fact that I've violated some moral precept. And once again, I concur.
The facts are getting more and more bizarre and unlikely. I don't think lying, cheating and hiding can possibly improve your real relationship. The best relationships are based on honesty and caring.
I was watching a documentary the other day where several people were interviewed who had cheated on their spouses using an adultery Web site AshleyMadison.com. (
Here's an article about it. They paid some firm to arrange alibis and all the other rigamarole to make sure their spouses were entirely in the dark. And if what these people say is true, the scam worked. The wife (typically but not exclusively) is none the wiser, and some of them swear on a stack of bibles that their relationships have improved as a result. They have various stories to say why that might be, but most of them devolve to learning through the affair just how much they love their spouses. We might want to scoff at such stories, but there is no reason to disbelieve them.
It's important to also point out that just because these stories are true, we should not give up on the conventional wisdom. All the truth of these stories entails is that it is possible to have an affair with no harm done. And if THAT's possible, then our consequentialist principle should be rejected in favor of something else.
Maybe we should ask the wife if she feels it would improve the relationship. If so, then yes.
But that's changing all the terms of reference. The question is whether I should be able to act out a desire if I don't harm anyone. Cheating on my wife harms my wife if she finds out. If she doesn't find out, how is she harmed, especially if the relationship remains as good as it ever was (or, as has been claimed at times, improved)?
The question is whether it is wrong to do so
if you can arrange it so she can't ever know about it. If one can, it's apparently permissable (based on the ethic of "You can do it but only if it doesn't cause any harm").
Sure we do. See the article I linked to and the testimonials on the Web site.
I say go with the empirical data we have, which shows that what tends to lead to happiness is real, intimate, trust-based relationships, not cheating, lying and hiding.
Hey, we're talking about a one-off here not a lifestyle.
That semi-facetious point aside, let me just say that this piece of homely, stock wisdom is entirely trustworthy. Nevertheless, it is possible (and that's all I need for my argument) to have a one-off tryst with no harm done. And if that's so, the consequentialist principle is refuted.
Let's ask Governor Sanford whether he's happier with or without cheating. Let's ask his wife, too. Also Senator Ensign.
No doubt, there are those who cheat and get caught. Is the problem the cheating or getting caught? If our principle is as the OP suggests, if we are permitted to act on our desires unless doing so causes harm, the question is how to mitigate or eliminate the harm. If one can do that, one can act on just about any desire one has.
Why put yourself through the suffering? Let me get this. We have to assume that there's no risk anyone will find out, that you have no normal compunction or guilt, that you will not worry about getting caught, that you will not actually get caught, that you don't mind sacrificing the intimacy and trust of a real relationship, that one time sexual gratification is worth more to you than a lifetime of trust, and that reducing your intimacy and trust in this way will actually improve your relationship in some way, and that you are sure of all those extremely unlikely things. I submit that these facts are so unlikely, so remote, that we can treat the whole hypo as irrelevant.
A few disclaimers. The only thing my story needs is the reduction of harm to zero or to such a small level that it's hardly worth considering. Doing this does not require the sort of psychology you attribute to my hypothetical character. No plan is perfect, so no, he can't be 100% sure he won't get caught, but the chances are,
ex hypothesis, minimal, so he doesn't particularly worry. And of course the lifetime of trust
is worth more than the one night stand. That explains the care with which he ensures his wife won't find out. If his wife doesn't find out, there's no loss of trust or intimacy. And of course, there's no need to assume that the intimacy of the relationship will improve. I only submit that it's possible, at least if we take the stories of some cheaters at face value (something we have no reason not to do). And all I've said is that if this is true, the consequentialist ethic gets turned on its head so that cheating may be obligatory. The fact you find this result counterintuitive (as I do) shows just that you don't seriously hold to a consequentialist theory of ethics.
In general, I am not interested in bizarre ethical hypos, with babies abandoned on streetcar lines and fat men waiting to be pushed in the way. What I'm interested in is helping people how best to live their actual lives. In the general course of things, breaking your word, lying to your mate, and destroying the most important trust and intimacy you have tends to be destructive, and I advise against it.
So do I.
