—“So how does one define morality in this view [Propertarianism]? What is its foundation?”—
At a minimum, non-impositions of costs upon property-en-toto, and at the median a prohibition on free riding, and at the maximum the requirement for mutual insurance, thus preserving the incentive to cooperate and gain the disproportionate rewards of cooperating all along the cooperative spectrum. (This is in fact, what our moral intuitions evolved for and remain.)
-“What is operationalism and how does it work in concrete terms?”—
A testimony (or promise or description) stated as an existentially possible sequence of subjectively testable operations.
Explanation: It is the equivalent of a proof in mathematics: a test that a mathematical statement can be constructed from existentially possible operations. It is the equivalent of a recipe for baking a cake (or any other repeatable operation.) The purpose of operationalism and Eprime is to ensure that the individual has laundered error, bias, wishful thinking and deception from his speech. An example would be your use of the terms ‘morality, view, foundation, what-is, ‘ and ‘concrete’ which are vague analogies sufficient for colloquial speech but both illustrate that you do not know the existentially possible terminology you could and should use if you know the existential rather than analogistic construction of those concepts.
In moral speech operational tests not only force the speaker to know what he is talking about, but also, when combined with full accounting, parsimony, and productive, fully informed, voluntary exchange and a prohibition on negative externalities, then it is very obvious at each operation (action) to determine if someone is acting morally or immorally. It is a tedious manner of speech (just as programming is a tedious means of instruction) however out of this tedious requirement, it becomes very hard to error, bias, wishfully present, and deceptively convey ideas.
–“I find this suspicious: “The problem is that [propertarianism] really requires a course””–
Why? Why do people need a course on Nietzche, Marx or Postmodernism? Don’t first year micro and macro economics, each form of mathematics, first year public choice theory, basic rhetoric, evolution, first year accounting, first year contract,.. and on and on require a course?
Why is it that you think that something that has taken 2500 years to solve, by a host of minds greater than mine, should be somehow trivial to convey? I’m a pretty smart guy and I spent two entire years on truth. Can you even tell me what ‘true’ means?
So it’s non logical that this should be an easy subject. Brouwer, Bridgman, Popper, Hayek and Mises failed. Why should it be trivial?
