Well, a member of the crowd certainly has the right to shoot the madman. But they don't have a right to use the man's gun without permission. So, you're really talking about two different things. Saying they have a right to shoot him does not give them carte blanche to take whatever gun they wish to do it.[/quote]
Shanek, believe it or not, this implies that you follow the natural rights crowd.
I described in my case how they complemented each other. You have done NOTHING to refute that.
First, you have to understand the differences between natural rights and utilitarianism. As Victor stated, the former is a priori, while the latter is empirical. Second, given the nature of utilitarianism (as an *empirical* philosophy), it can be used to justify all kinds of political-social-economic systems. A utilitarian can be anarchist, socialist, communist, national socialist, fascist, laissez-faire, or welfare statist.
In the case of Nozick, who says we have certain rights that no one may take away under any circumstances, the effects of my hypothetical minimum wage law do not interest him. He views it as a violation to free contract, and therefore immoral. A utilitarian libertarian, however, would say, "Hmmm... let me examine the evidence. Ah, yes, you're right, that minimum wage law maximizes utility, therefore we ought to stick by it (free contract be damned)."
A natural rights libertarian doesn't have to read the newspaper or scrutinize the evidence because she views everything in terms of (her conception of) liberty.
So in the case with the mad man, a natural rights person would say that you cannot steal the gun from a third party because it violates his ownership of property. A utilitarian, under these circumstances, construes the question in terms of happiness. She allows that rights promote happiness, but perhaps a minor violation of this sort (in one particular instance), will serve the greater good.
Utiltarianism is often derided by natural rights theorists (especially Randians) as "collectivist" -- and I don't disagree with the description (their pejorative subtext notwithstanding).
Then refute my description of how I came to be both at the same time. Until you do that, there's really nothing more to say. [/B]
No you're confused for all of the reasons above. You need to distinguish between philosophical foundations and the beliefs that initially compelled you toward libertarianism.
Imagine a communist who wants to achieve her vision of equality. She views equality as the over-riding principle (and nationalization as a means to that end). But, at the same time, she believes that this equality will also result in the greatest good for the greatest number. Everyone will be happy living an idyllic Marxist paradise. She thinks nationalization will cause the economy to boom, producing all kinds of wonderful goods and services, culminating in the "greatest good for the greatest number." That is to say, she believes perfect equality maximizes utility; and any system designed to maximize utility will also involve perfect equality.
Now suppose I confront this person on the JREF forums. I say, wait a second, which principle is more important? Suppose equality does not result in maximum happiness...
If she's like you, she can't grasp that concept. "Why wouldn't it?!" she shrieks. "I've believed in both equality and utilitarianism for years!" Oh, but suppose that with a little, tiny bit of inequality, you could increase production, thus increasing happiness.
"That's impossible!"
No, just suppose... Imagine, if you can, a society that compromises equality for happiness....
"But if they're compromising equality, then they won't be happy."
No, that's an empirical claim. Just suppose that's false: are you still in favor of equality even if it means there are other systems that could better achieve maximum happiness?
And any remotely sane person would see the distinction and choose one (or neither, abandoning their belief system altogether).
A communist chooses:
I believe in utilitarianism, which just happens to instantiate a socio-economic system of perfect equality.
I believe in perfect equality, which, as a consequence, achieves the greatest good for the greatest number.
