#3543·Bart Vanderhaegen, 27 days agoDo you mean "HTV is underspecified by Deutsch" ? But that is not a criticism ? It does not point to a mistake/ contradiction with HTV ?
That’s only one of several criticisms.
#3534·Bart Vanderhaegen revised 29 days agoI think the first question is whether HTV is a real concept (because if real, it is programmable, and via EC to arbitrary precision)
To understand if it’s real, we need to seek counterexamples/ counterarguments, not demand that a program can be written
What would such a program prove ? Not that HTV is real, but also not that we understand something about HTV.
That’s because Deutsch only says : no program = no understanding. That implies having a basic conception programmed can mean that you understand something. Take the season’s example, you could simulate that replacing Gods would not change the fact that they cry but that tears are not the same as rain etc. Granted, this would only be for 1 example, extending HTV to general examples would be needed. But with such basic program, for 1 example theory, we can’t conclude either that we do not understand anything about HTV.
Criticising HTV would anyway be the more important first step. Maybe examples of good theories with some ETV aspects (compared to rejected theories) in them could reveal some more.

That could work, yeah. What other criticisms of HTV can you think of?
#3524·Erik Orrje, 29 days agoYes, here's a new version:
Some minds with one coercive memeplex are more like dictatorships.
To make a new version of #3516, revise the idea. See that pencil button?

The linked blog post has several criticisms of HTV.
#3530·Fitz Doud, 29 days agoI think your challenge asks for the wrong kind of thing. Deutsch’s “hard to vary” is a guideline for criticizing explanations, not a step by step decision algorithm. In this paper he says scientific methodology does not prescribe exact procedures, and that “better” explanations are not always totally rankable in a clean, mechanical way. “Hard to vary” mainly means avoiding explanations that can be tweaked to fit anything, because then they explain nothing, so the lack of a universal scoring program does not refute the idea.
THE LOGIC OF EXPERIMENTAL TESTS, PARTICULARLY OF EVERETTIAN QUANTUM THEORY
https://www.constructortheory.org/portfolio/logic-experimental-tests/
From the Paper:
An explanation is better the more it is constrained by the explicanda and by other good explanations,[5] but we shall not need precise criteria here; we shall only need the following: that an explanation is bad (or worse than a rival or variant explanation) to the extent that…
(i)
it seems not to account for its explicanda; or
(ii)
it seems to conflict with explanations that are otherwise good; or
(iii)
it could easily be adapted to account for anything (so it explains nothing).
Deutsch’s “hard to vary” is a guideline for criticizing explanations, not a step by step decision algorithm.
But he says to use hard to vary as part of a decision-making algorithm. As quoted in my blog post:
“we should choose between [explanations] according to how good they are…: how hard to vary.”

Hey Fitz, welcome to Veritula.
I realize that DD doesn’t think of it in strict, procedural terms, but I just don’t think that’s good enough, for several reasons. One is that it’s too vague, as I explain here. We don’t know how to actually do anything he says to do, beyond broad suggestions.
For something to be a core virtue, it needs to be a virtue that should always be applied in any situation where it can be applied. Forgiveness is not something that should be applied in relevant all situations, so I don’t believe it is a core virtue.
At best it would be an applied virtue, as an expression of Justice.
I actually think people are too forgiving in some ways.
I’ll think about adding it to the applied virtues list.
