Thanks to all of you for helping out For the time being I believe that truthness IS the word.

Michael Korovkin Feb 21, 2010:

Jim is dead right Besides, there are no TRUE synonyms! LV and LP (P for plausibility) are not truthness. Even a logically invalid statement may be – how do I put it now? – truthnessful (huh, huh!). The term appeared in the beginning of the 1900s parallel, as I said already, with the develpment of relativism in physics and, hence?, the renewed relevance of epistemology. Go for it, Igor: truthness is your best beast! Truthness is in the mind of the "averrer"!

Igor Popov (asker) Feb 21, 2010:

Dear friends,
If you have time you may wish to know more about the term in question at
http://www.cogsci.northwestern.edu/cogsci2004/papers/paper21...
In that one-page article they use another term L-validity (though not qualified as I understand)

Igor Popov (asker) Feb 21, 2010:

At the moment, I believe truthness is the closest word. Of course, truthness is not a neologism. What I meant was that the Russian word истинностность is. Compared to истинность (veracity) which is used for centuries the Russian word истинностность is new for the Russian language.
Thanks to all.

"Truthness" is no neologism "Truthness" is probably a 19th-century coinage, if not earlier. It appears in the 1913 Webster's. Not a concrete noun as far as a quick scan reveals, Michael, but a quality of an argument (irrelevant to its actual truth or falsity).

Michael Korovkin Feb 21, 2010:

Apples & pears Sorry my computer doesn't show me other discussion entries, so I don't know what other people say. Anyay, I see what you mean. In that case, what comes to mind is, alas, verbal form "to aver" (to claim as truth). It would "substantiate" only as a gerund "averring", which is not very elegant... nor is "istinnstnost" though! There is another term knocking around modern philosophical writings – also quite goofy: "truthness". It came into force together with the powerful return of epistemology and particularly – philosophical relativism. For example most "truths" of quantum mechanics are not directly verifiable; they are also sensually unavailable, ambiguous and subject to restrictive laws only. They are, therefore, "averring" their claims: in a word, they are "truthnesses". Parenthetically, I don't buy for a minute any concept that can't be expressed with a reasonable degree of elegance. Thus, I buy quantum mechanics (at least a part of it) but not the contemporary pseudo- o rather post-philosophical perverse ravings about it's "truthness". But that's, obviously, besides the point. Use "truthness" and be done with it!

David Knowles Feb 21, 2010:

I was going to suggest decidability/разрешимость but I think Jim has the answer with another neologism, so I'll bow out!

Jim Tucker (X) Feb 21, 2010:

truthness and logic Logicians use "truthness" extensively. I'm assuming the Russian term is a calque of the English one, which is a typical Anglo-Saxon coinage. Just to add:

Unlike linear logic (boolean and fuzzy, not Girard's linear logic), Multidimensional logic accepts more than one value of truthness. It can handle contradictions and uncertainties. The blue line that goes from (0,1) to (1,0) represents fuzzy logic, we'll call it the "fuzzy line", since we will be mentioning it. This is, when the values of truthness complement each other (their sum is 1), and thus, there's no contradiction. Each axis represents a condition. For example: true and false. So, when the value of truthness complements the value of falseness, there's no contradiction, and fuzzy logic can deal with these statements. So we can state that multidimensional logic is a meta-set of fuzzy logic.

Igor Popov (asker) Feb 20, 2010:

Michael, I really appreciate you collaboration. That is the point. The word istinnostnost (not istinnost) is rather new for the Russian language, it is almost a neologism. It is widely used in the terminology of logic. I can give the simplest example as follows: let us say: apple is apple – this is a true assertion; apple is pear – this is a false assertion but both assertions are ‘istinnostnostny’ (in Russian истинностностны). You see we can say that both of them are true, but it is not exactly the word because both of them are ‘istinnostnostny’(in Russian истинностностны) – and here is the problem – how to say it in English. Actually as Shakespeare said: ‘Tired with all this for restful death I cry” :-)

Michael Korovkin Feb 20, 2010:

Shucks! And sorry! I DID confuse it with istinnost for a simple reason of not having ever heard of "istinnostnost'" (and that's in spite of having a doctorate in cultural anthropology, an interest in epistemological models and having taught philosophical ethics for years... in the anglophone environment though... and that's my only excuse, I guess). Moreover, now that I see it I'm awed by the term's almost comically preposterous incongruity making one hard put to believe that it really exists! Istinnostnost', really? Truthfulfulnesness? Wow, yo, I'll be blowed! The essential truth?

Igor Popov (asker) Feb 20, 2010:

It is almost impossible to explain the connotation of this Russian word istinnostnost (again don’t confuse it with istinnost) I’ll try before I’ve gone crazy:

Truthfulness is the quality of being truthful.
Verity is the quality or state of being true.

But istinnostnost is (must be, would be) an attribute of truth.
Not the quality but an attribute.
Though I feel my explanation will not be enough.
Thanks all of you for you time anyway.

Igor Popov (asker) Feb 20, 2010:

David, thank you very much. Actually, verifiability is very close to what I need. However, I’ve never met verifiability in terms of logic, perhaps you have.
The problem is that istinnostnost is a specific logical notion which equivalent I was unable to find in English. I feel that the closest one is true-falseness but I am not sure if it is generally used as a logical notion in English.
This is a philosophical text and I now for sure that the word verification is commonly used in the meaning of determination of truth. But istinnostnost is still a problem.

David Knowles Feb 20, 2010:

verifiability = проверяемость Is this close?

David Knowles Feb 20, 2010:

How about "verifiability"? A system that is verifiable is capable of being shown true or false: it has a truth-value. It's a term used in logic. I'm sure it has a standard translation though!

Igor Popov (asker) Feb 20, 2010:

Istinnostnost – is an attribute of the system consisting of relevant questions and answers; therefore, when determining the meaning of it, if at all possible, the questions and answers play head-to-head.

Igor Popov (asker) Feb 20, 2010:

Спасибо большое, Michael На счет Truth надо подумать, хотя мне больше подходит логический термин truth-falseness или даже truth value в моем контексте.

Verisimilitude – это скорее правдоподобность, правдоподобие.

В данном случае требуется английский вариант термина истинностность в таком контексте - истинность или ложность как качества, истинностность - как признак. Есть другая трактовка - истинностность - атрибут комплекса, состоящего из релевантных вопросов и ответов, поэтому, если это вообще возможно, при установлении ее значения вопрос и ответ играют совершенно на равных.
Вот такая непростая задача.
