Juan, if that’s where libertarianism led, wouldn’t that demonstrate that libertarianism might be flawed?
JAlanKatz, the distinction I tried to make is based on the following classic example: Our right to self-determination almost certainly includes a presumption that if we want to kill ourselves, then that should be our prerogative. No one is justified in requiring that we continue to live if that’s not what we want–at least, that’s what I take most libertarians’ position to be. Further, that same right to self-determination, and our right to bodily integrity, suggests that a person would not be justified in grabbing someone forcefully without permission and preventing them from going about their way.
And yet, if you saw someone walking aimlessly into an intersection as traffic was speeding by, not looking where they were going, you would certainly be justified in grabbing them and saving their life. The idea would be that even though you acknowledged their right to kill themselves if they wanted to, and their right not to be grabbed, you had reason to believe that their choice to enter the road was not based on their desire to be killed, and that you were doing them a favor by grabbing them. You would be operating under the assumption that their choice reflected inadequate knowledge of the full consequences of stepping into the street (as I said, they weren’t paying attention), and that if they knew what you did, they would choose differently.
We might further imagine that upon grabbing the individual and warning them not to go out in traffic, you discovered that they were extremely drunk. In their stupor, they claim that they really do want to kill themselves, because they’re really mad at the world, and that you should let them go. Now what? On one hand, you can imagine that there’s a very good chance that they’re just drunk and temporarily stupid; if they were thinking clearly, they wouldn’t want to kill themselves, but their impaired reasoning is leading them to a different conclusion. If this were actually true, and it were a fact that the only reason that the person wanted to kill themselves was that they were drunk, would you be justified in continuing to restrain the person, even though they asked you to let them go?
If you say yes (and I do; I think it would be ridiculous to say no if we knew that they only wanted to kill themselves because they were drunk), you have to confront a worrisome possibility. Perhaps this individual really does want to kill themselves, and it isn’t just the alcohol talking. If that’s the case, then what you’re doing seems extremely coercive and paternalistic. As libertarians, we should oppose that sort of thing. But perhaps there’s no way to actually tell whether the person is simply drunk and making a stupid decision or whether they really want to kill themselves. So what do you do? To be honest, I don’t know what the right answer is. I don’t think it’s obvious that we should be allowed to restrain the drunk indefinitely, but I also don’t think it’s obvious that we should be morally obligated to let them go kill themselves.
Hopefully it should be clear how this relates to children having sex. There are a lot of bad things that can come from having sex before you’re mature enough to handle it, and the naivity of youth can cloud a child’s judgment so that they might not be able to properly think about the choice they’re making. But at the same time, if a child isn’t making a stupid choice, it does seem unjustly coercive to stop them from having sex. So what do you do? To be honest, I’m not sure; I think it’s a tough case. But that’s not because libertarianism is incoherent or muddled; it’s that there are conflicting values at play, and it’s sometimes hard to know what is the right thing to do.
