This is mostly in response to John’s fine piece titled “Why Libertarians Are Like Judgy Know-It-Alls Who Don’t Have Kids”, which can be found here.
The problem with arguments against normative theories that appeal to “what works” is that in them is already built a normative theory. As a result, they beg the question.
This took me a long time to realize, though Aaron Haspel clearly knew about this for awhile now. When I first met Aaron at John’s place and this topic came up, Aaron nonchalantly rattled off the above observation as though it were a matter of course. It was humbling and, to be honest, mildly embarrassing.
At any rate, in this fine piece, John writes that “Much in America works. And works very well.” But to libertarians (and Marxists, etc.), violating people’s rights doesn’t count as “working”, even if the overall arrangement is generally desirable or pleasant. This point is brought out especially well by Ursula Le Guin’s award-winning short story, “The Ones Who Walk Away from Omelas.” In this story, Le Guin writes of a utopian city known as Omelas.
Omelas is shimmering, bright and beautiful. Everyone is happy, has food to eat and there is no social strife. Everything works wonderfully. However, Omelas has a dark secret. It turns out that the city’s splendor depends on the infliction of suffering and misery on a single child who is locked away in a basement.
When they come of age, each Omelian citizen is taken to see the child. The story is about the ones who, after seeing the child, decide in the dead of night when everyone’s asleep to walk away from Omelas.
The point is this: To those who walk away from Omelas, the city doesn’t “work.” For before we can do or judge what “works”, we need to know what counts as working. As normative theories, Marxism, libertarianism and (insert political philosophy here) try to provide the criteria for what counts as working.
Now, this does not take anything away from John’s insight that libertarians are very wrong—and indeed, childish—when they complain that the government does nothing well. The government undoubtedly provides many valuable services, and sometimes does so well and efficiently. To categorically say otherwise is false and, worse, dogmatic.
But on political philosophy more generally, I agree with Marxist philosopher G.A. Cohen that our principles of justice (which are delivered by our particular political philosophies) ought to be fact-insensitive. That is, I don’t think facts about a principle’s feasibility (in terms of people’s willingness to comply with it) should count as evidence for or against the principle. More concretely, “But, in the real world, people will always rape!” is not a valid objection to “Rape is wrong.”
As the saying goes, Marxism may not work “in practice” because we are too selfish and greedy to be good Marxists, but most people agree that it’s morally the right way. That is enough to concede that Marxism is true. (Libertarians, of course, disagree.) Indeed, Marxism is just a normative thesis, and normative claims do not entail anything about what descriptively is or will be the case. Their truth stands independently of it.
Appeals to “what works”, then, either don’t count as any evidence against Marxism or libertarianism, or beg the question against them.
