I said this recently:
Conservatives rightly defend free markets because they exemplify the learning from trial and error that underlies the wisdom of voluntarily evolved social norms — norms that bind a people in mutual trust, respect, and forbearance.
Conservatives also rightly condemn free markets — or some of the produce of free markets — because that produce is often destructive of social norms.
What about “libertarianism”* and leftism? So-called libertarians, if they are being intellectually consistent, will tell you that it doesn’t matter what markets produce (as long as the are truly free ones). What matters, in their view, is whether the produce of markets isn’t used to cause harm to others. (I have elsewhere addressed the vacuousness and fatuousness of the harm principle.) Therein lies a conundrum — or perhaps a paradox — for if the produce of markets can be used to cause harm, that is, used in immoral ways, the produce (and the act of producing it) may be immoral, that is, inherently and unambiguously harmful.
Guns aren’t a good example because they can be (and are) used in peaceful and productive or neutral ways (e.g., hunting for food, target-shooting for the enjoyment of it). Their use in self-defense and in wars against enemies, though not peaceful, is productive for the persons and nations engaged in defensive actions. (A war that contains elements of offense — even preemption — may nevertheless be defensive.)
Child pornography, on the other hand, is rightly outlawed because the production of it involves either (a) forcible participation by children or (b) the exploitation of “willing” children who are too young and inexperienced in life to know that they are subjecting themselves to physical and emotional dangers. Inasmuch as the produce (child pornography) can result only from an immoral process (physical or emotional coercion), the produce is therefore inherently and unambiguously immoral. I will leave it to the reader to find similar examples.
Here, I will turn in a different direction and tread on controversial ground by saying that the so-called marketplace of ideas sometimes yields inherently and unambiguously immoral outcomes:
Unlike true markets, where competition usually eliminates sellers whose products and services are found wanting, the competition of ideas often leads to the broad acceptance of superstitions, crackpot notions, and plausible but mistaken theories. These often find their way into government policy, where they are imposed on citizens and taxpayers for the psychic benefit of politicians and bureaucrats and the monetary benefit of their cronies.
The “marketplace” of ideas is replete with vendors who are crackpots, charlatans, and petty tyrants. They run rampant in the media, academia, and government.
If that were the only example of odious outcomes, it would be more than enough to convince me (if I needed convincing) that “libertarians” are dangerously naive. They are the kind of people who believe that disputes can and will be resolved peacefully through the application of “reason”, when they live in a world where most of the evidence runs in the other direction. They are as Lord Halifax — Winston Churchill’s first foreign secretary — was to Churchill: whimpering appeasers vs. defiant defenders of civilization.
The willingness of leftists (especially office-holders, office-seekers, and apparatchiks) to accept market outcomes is easier to analyze. Despite their preference for government dictation of market outcomes, they are willing to accept those outcomes as long as they comport with what should be, as leftists happen to see it at the moment. Leftists are notoriously unsteady in their views of what should be, because those views are contrived to yield power. Today’s incessant attacks on “racism”, “inequality”, and “sexism” are aimed at disarming the (rather too reluctant and gentlemanly) defenders of liberty (which isn’t synonymous with the unfettered operation of markets).
Power is the ultimate value of leftist office-holders, office-seekers, and apparatchiks. The inner compass of that ilk — regardless of posturing to the contrary — points toward power, not morality. Rank-and-file leftists — most of them probably sincere in their moral views — are merely useful idiots who lend their voices, votes, and money (often unwittingly) to the cause of repression.
Leftism, in short, exploits the inherent immorality of the “marketplace of ideas”.
Is it any wonder that leftism almost always triumphs over “libertarianism” and conservatism? Leftism is the cajoling adult who convinces the unwitting child to partake of physically and psychologically harmful sexual activity.
* I have used “sneer quotes” because “libertarianism” is a shallow ideology. True libertarianism is found in tradistional conservatism. (See “What Is Libertarianism?” and “True Libertarianism, One More Time“, for example.)
