Ha! I like that, and I’ve never heard it before: thanks for sharing it. And yes I do think many libertarians, if they thought about it, would find themselves struck by that kind of cognitive dissonance.
Now, the type of deontology espoused by libertarians (e.g., Rothbard, Hoppe…) is not “divine command theory” providing an objective ultimate end and saying that certain actions must (not) be performed under any circumstances, regardless of what any persons’ preferences are. Rather, the only purpose of these theories is to resolve disputes between people whose preferences conflict. So,
- If people agree on an ultimate end (e.g., prosperity, happiness, and long life for virtually everybody), then there is no fundamental dispute to resolve – it is not necessary to call upon a deontological theory in the first place.
- Only if people disagree at such a fundamental level that their preferences cannot be reconciled by pragmatic arguments (like Mises’s), does it become necessary to invoke deontology.
- In that case, however the dispute is resolved, someone is going to be happy and someone is going to be unhappy – it’ll never end up that both of them are unhappy.
What do you think? Do we ultimately have to involve an interpersonal utility comparison to object to deontology in this way?
But if that deontology has no bearing on either party’s ends, neither would be convinced by it unless they were indoctrinated to believe that it was an end in itself. Thus the deontology can only ever be a noble lie: a curiously cerebral superstition whose only merit is not via any truth, but only via the extent that people have been indoctrinated into accepting it. “Because-I-said-so” indoctrination is a thin reed upon which to base society. Eventually the mind of man would overthrow it, in the unlikely event it was ever yoked by it in the first place.
And we have no need of any such noble lie anyway. The preponderance of individuals would benefit vastly from a pro-capitalism system of laws. If they are convinced of that fact, they will support it. And, again, as la Boetie, Hume, Mises, Rothbard, and Hoppe all agree, social orders are fundamentally based on majority opinion; so if they support it, it will happen. Any of the tiny number of people who might actually materially benefit from an anti-capitalist system of laws, and are aware of the fact, don’t need to be sold deontology. They can simply be dealt with by the courts and constables (or PDAs) that would be characteristic of such a condition of popular opinion.
