Is there any constructed language that eliminated all fallacies related to how language works, that made extinct all fallacies that could be made extinct by creating a language from scratch to avoid them?

Some example of those fallacies: https://en.wikipedia.org/wiki/Category:Verbal_fallacies

1 Answer 1


Looking at the list of fallacies you quote, I would say this is not possible — most of them have got nothing to do with the language itself, but with the way it is used. It's a bit like making a kitchen knife that you cannot use to hurt someone with.

The Fallacy of Composition is related to reasoning. I cannot think of any way that a language can make that impossible. As long as you have expressive power in the language to express anything, you can express incorrect reasoning as well. The same goes for False Attribution, which is about how you use language, not anything in the language itself.

Loki's Wager refers to the absence of clear definitions or boundaries. The world is not clear-cut, so language cannot be like that either. Defining where the head starts and the neck ends is unrelated to language. Unless you want to accompany each word in that language with a book that defines exactly what it means.

Even the Fallacy of Accent is a problem, unless you take stress patterns out of the language, which then is a lot less usable, as stress is a good way of expressing nuances of meaning.

Syntactic ambiguity is about the only one which could be avoided through careful language design. But most 'usable' languages have some of that as well, especially if they are reasonably complex.

Most of these verbal fallacies are to do with the way you use language and express meanings, which you could do in any language. Syntactic ambiguities crop up more often than you would think, but unless you are a linguist, you won't even notice most of them, as it is usually very clear which meaning is the appropriate one in the context.

So, my answer is no, because it is not even possible to do that.

  • The fallacy of accent was removed by lojban, to make a question you put the word xu somewhere at the sentence (you don't use ? for it) the word before the xu is the word you are stressing. This fixes fallacy of accent because you need to say xu to both make the question and stress it and the specific part of the sentence the word xu is will dictate the stress, saying the same sentence in a different way will do nothing.

  • Fallacy of division use as example "...2nd grade in Jefferson elementary eats a lot of ice cream" you can't know if 1-The average amount of icecream the students of this second grade eat is alot of ice cream. 2-The median amount the students eat is alot. 3-The total amount they class eat collectively is alot of ice cream. 4-Each person at the class eat alot of ice cream. This could be solved by forcing the writer to specify all the choices that apply when telling that, so he can't be vague as in english, if some of the choices is not said is because it don't apply.

    Sure -- accent would be possible. Being not vague makes a language pretty much unusable, as you have to be so wordy in every little thing you say. But you asked for all fallacies to be avoided. Commented Feb 17, 2020 at 22:45

    @minoret, xu is used to indicate a question. It can't be used when the sentence isn't a question but a statement. "I didn't buy the car" compared to "I didn't buy the car" are two different statements requiring emphasis to differentiate, and neither are questions. Commented Feb 18, 2020 at 16:05
  • Isn't the fallacy of accent more of a shortcoming of many writing systems that don't (usually) indicate accent even though it carries meaning? Prosody is part of the language after all. The ambiguity only arises once you leave it out when writing your language down.
