How Does Veritula Work?
#5175·Liberty Fitz-Claridge, 6 days agoI think we agree that the conjecturing and criticising of explanations is where the progress happens, and this choice you're saying people make at the end among conjectured theories is (relatively) mechanical. But I would also point out that trying to measure how HTV a theory is is as futile and scientistic as trying to measure moral worth. Yet it's still possible to have meaningful discussions about morality. I can't measure the moral value of murder but I can meaningfully argue it's worse than theft. So I think the claim that "if you can't program it you don't understand it" doesn't apply so universally as #3020 implies.
I think you may have misunderstood me. I asked how I can know that our discussion about HTV will be productive if we continue it now. (For context and for others: I’ve found that Liberty and I have roughly the same discussion in various venues every few months or so. I raised this issue in the linked X thread.)
I didn’t ask you to continue the object-level discussion itself.
Please address my concern before continuing the discussion.
#3924·Dennis HackethalOP, 7 months agoIt seems that you've taken the idea of hard to vary as saying that the process of choosing between competing theories is just about measuring how much of this trait they have. One clearly wouldn’t get better explanations from doing that, as it would just be a mechanical way of judging theories.
Yes, but as I understood Deutsch, this process of choosing happens after one has conjectured and criticized a bunch of explanations. I don’t think he suggests that the application of the HTV criterion makes theories better, only that we should use it to choose between explanations after they have been guessed and improved.
So the process of choosing between already existing explanations really is “just about measuring how much of this trait they have.”

should_adopt?andpending_criticismsare implemented in terms of each other. Doesn’t that cause an infinite regress?
No because 1) there’s always a finite amount of deeply nested criticisms, and 2) the discussion graph is acyclic.

#5096·Sam Cymbaluk, 15 days agoif somebody suggests some system they can’t put into practice, then the system is no good.
Agreed. My point is that you can't refute a flaw by saying the flaw doesn't have a workable system to resolve it. "Your boat has a hole in it". "Yeah, well I don't have any way of fixing it". That doesn't resolve the criticism of the boat. If it's unfixable and a real flaw, you might just need a new boat.
Assuming Sam did mean to criticize my opposition to assigning strengths to criticisms:
The issue isn’t that we don’t have a way to fix the hole. (We often do.)
The issue is that we have no rigorous way to tell how big the hole is. So, rather than evade criticisms by saying ‘but it’s only a small hole’, I’m saying we should always either fix holes in the boat, no matter their size, or choose a different boat.

Unclear what the boat stands for.
Sam criticized my idea, so presumably he means for the boat to represent #4711. But the way his criticism is phrased, it sounds more like the boat represents the methodology of assigning strengths to criticisms.

Logically, yes. But in practice, it won’t be the same.
For example:
Idea A: ‘Newtonian gravity is true.’ → Has pending criticisms (some predictions don’t match observation).
Idea B: ‘Newtonian gravity is not true.’ → Also has pending criticisms: ‘Not helpful’; ‘Doesn’t tell us how gravity works’; etc.

#5085·Sam Cymbaluk, 16 days agoThis approach does not specify how long you should spend coming up with criticisms before adopting it, therefore it cannot be put into action as stated. The delay must be nonzero otherwise, the fresh idea "you should ignore criticisms" would nullify the system.

Expanding on #2112…
If an idea, as written, has no pending criticisms, it’s rational to adopt it and irrational to reject it. What reason could you have to reject it? If it has no pending criticisms, then either 1) no reasons to reject it (ie, criticisms) have been suggested or 2) all suggested reasons have been addressed already.
If an idea, as written, does have pending criticisms, it’s irrational to adopt it and rational to reject it – by reference to those criticisms. What reason could you have to ignore the pending criticisms and adopt it anyway?
Or, simplified:
It is rational to adopt only those ideas which, as written, don’t have pending criticisms, and to reject ideas that do.
Is rejecting an idea equivalent to adopting it's negation?
#2182·Dennis HackethalOP revised 10 months agoYou’d know it’s a DDoS long before reviewing all the contents. That amount of criticism in a short time is suspicious, so you’d investigate for signs of coordination. Companies investigating actual DDoSes don’t need to review every single request to know they’re being DDoS’ed. And no otherwise reasonable person could blame them if a few good requests get dropped during their defense efforts.
But what if the idea that you should be suspicious of a large volume of criticism in a short time has pending criticism itself?

#3028·Dennis HackethalOP revised 9 months agoSay the thought of adopting some idea with no criticisms bothers you.

#4471·Dennis HackethalOP revised 5 months agoHow Does Veritula Work?
Veritula (Latin for ‘a bit of truth’) can help you live a life guided exclusively by reason.
To reason, within any well-defined epistemology, means to follow and apply that epistemology. Unreason, or whim, is an undue departure from it. Epistemology is the study of knowledge – basically, the study of what helps knowledge grow, what hinders its growth, and related questions.
Veritula follows, and helps you apply, Karl Popper’s epistemology, Critical Rationalism. It’s a continuation of the Athenian tradition of criticism and the only known epistemology without major flaws.1
Critical Rationalism says that ideas are assumed true until refuted. This approach leaves us free to make bold guesses and use the full arsenal at our disposal to criticize these guesses in order to solve problems, correct errors, and seek truth. It’s a creative and critical approach. Critical Rationalism is a fallibilist philosophy: there is no criterion of truth to determine with certainty whether some idea is true or false. We all make mistakes, and by an effort, we can correct them to get a little closer to the truth. Rejecting all forms of mysticism and the supernatural, Veritula recognizes that progress is both possible and desirable, and that rational means are the only way to make ongoing progress.
Veritula is a programmatic implementation of Popper’s epistemology.
Veritula provides an objective, partly automated way to tentatively determine whether a given idea is problematic. It does not tell you what to think – it teaches you how to think.
On Veritula, ideas are discrete and immutable. Consider an idea
I:plaintextISince it has no criticisms, we tentatively consider
Iunproblematic. It is rational to adopt it and act in accordance with it. Conversely, it would be irrational to reject it, consider it problematic, or act counter to it. (See #2281 for more details on rational decision-making.)Next, someone submits a criticism
C1:plaintextI|C1The idea
Iis now considered problematic so long as criticismC1is not addressed. How do you address it? You can reviseIso thatC1doesn’t apply anymore, which restores the previous state with just the standaloneI(now calledI2to indicate the revision):plaintextReviseI ------------> I2|C1To track changes, Veritula offers beautiful diffing and version control for ideas.
If you cannot think of a way to revise
I, you can counter-criticizeC1, thereby neutralizing it with a new criticism,C2:plaintextI|C1|C2Now,
Iis considered unproblematic again, sinceC1is problematic and thus can’t be a decisive criticism anymore.If you can think of neither a revision of
Inor counter-criticism toC1, your only option is to accept thatIhas been (tentatively) defeated. You should therefore abandon it, which means: stop acting in accordance with it, considering it to be unproblematic, etc.Since there can be many criticisms (which are also just ideas) and deeply nested counter-criticisms, the result is a tree structure. For example, as a discussion progresses, one of its trees might look like this:
plaintextI/ | \C11 C12 C13/ \ \C21 C22 C23/ \C31 C32In this tree,
Iis considered problematic. AlthoughC11has been neutralized byC21andC22,C12still needs to be addressed. In addition,C23would have neutralizedC13, butC31andC32makeC23problematic, soC13makesIproblematic as well.You don’t need to keep track of these relationships manually. Veritula automatically marks ideas accordingly.
Since decision-making follows the same logic as truth-seeking, you can use these trees to make decisions, too. Veritula implements unanimous consent as defined by Taking Children Seriously, a parenting philosophy that builds on Popper’s epistemology. When you’re planning your next move but can’t decide on a city, say, Veritula helps you criticize your ideas and make a rational decision – meaning a decision you’ll be happy with. Again, it’s rational to act in accordance with ideas that have no pending criticisms.
All ideas, including criticisms, should be formulated as concisely as possible, and separate ideas should be submitted separately, even if they’re related. Otherwise, you run the risk of receiving ‘bulk’ criticisms, where a single criticism seems to apply to more content than it actually does.
Again, criticisms are also just ideas, so the same is true for criticisms. Submitting each criticism separately has the benefit of requiring the proponent of an idea to address each criticism individually, not in bulk. If he fails to address even a single criticism, the idea remains problematic and should be rejected.
The more you discuss a given topic, the deeper and wider the tree grows. Some criticisms can apply to multiple ideas in the tree, but that needs to be made explicit by submitting them repeatedly.
Comments that aren’t criticisms – eg follow-up questions or otherwise neutral comments – are considered ancillary ideas. Unlike criticisms, ancillary ideas do not invert their respective parents’ statuses. They are neutral.
One of the main benefits of Veritula is that the status of any idea in a discussion can be seen at a glance. If you are new to a much-discussed topic, adopt the displayed status of the ideas involved: if they are marked problematic, reject them; if they are not, adopt them.
Therefore, Veritula acts as a dictionary for ideas.
One of the problems of our age is that people have same discussions over and over again. Part of the reason is widespread irrationality, expressed in the unwillingness to change one’s mind; another is that it’s simply difficult to remember or know what’s true and what isn’t. Discussion trees can get complex, so people shouldn’t blindly trust their judgment of whether some idea is true or problematic, whether nested criticisms have been neutralized or not. Going off of memory is too error prone.
Veritula solves this problem: it makes discussion trees explicit so you don’t have to remember each idea and its relation to other ideas. Veritula therefore also enables you to hold irrational people accountable: if an idea has pending criticisms, the rational approach is to either abandon it or to save it by revising it or addressing all pending criticisms.
Many people don’t like to concede an argument. But with Veritula, no concessions are necessary. The site just shows you who’s right.
Using Veritula, we may discover a bit of truth.
Popperian epistemology has some flaws, like verisimilitude, but Veritula doesn’t implement those.
I’ve formalized some of these ideas in my first paper, ‘The Structure of Rational Thought’.
