    Language of logic, or Logic of language

    You can treat this as a language puzzle, or a logic puzzle. This is a puzzle in a loop.

    A guy makes three entirely voluntary statements, in the following order:

    (1) I'm an alcoholic.
    (2) I'm a gambler.
    (3) I'm a liar.

    Assuming that we agree that alcoholism, gambling and lying are vices, how many vices does the guy really have? One, two, three, or none?

    Re: Language of logic, or Logic of language

    I guess that he has none of them:

    if we take "I'm a liar" as a true statement we get that he is not an alcoholic nor a gambler. But then "I'm a liar" would be false too. (Supposing that he always lies about everything).

    So that's my conclusion. Would you tell me the right answer?

    Re: Language of logic, or Logic of language

    If we must not believe him at all as he is a liar, so we shouldn’t believe his statement as well that “I am a liar”. So I think no exact answers, it’s a vicious circle.Because liars don't lie always sometimes they can say the truth.But I feel that your answer will be surprising justinwschang. It’s a very nice brainstorming, thank you. I am curious about the others answer. . Later Edited:I gave the same answer as Boedicae without knowing her one, sorry.

    Please keep trying, it's a brain teaser.

    Can I ask a hint? Did you use the title to emphasise something about the word order. Or it's nothing to do with the question?

    No, nothing to do with word order.

    may be it is an only one vice because while gumbling he is drunk and he lies.
    These vices can be one as the situation is one

    I think that the only thing right in my answer is that I'm hallucinating, am I right?!!!

    Re: Language of logic, or Logic of language

    I've been beating my brains out all day trying to solve the puzzle... I'll try again:

    Lets' replace each statement with a letter:

    A = I'm an alcoholic
    G = I'm a gambler
    L = I'm a liar

    Obviously, the problem is L, so let's consider these 2 possibilities:

    1) L is true --------> If I were a liar I would never say it is true. So I don't think this option is correct.

    2) L is false ------> If I'm not a liar (I always tell the truth) then

    A is true
    B is true
    L is true

    Apparently, there is a contradiction now ( L is false and L is true ?????). From the point of view of Logic this is clearly a contradiction but, semantically it makes sense.

    If I were truly a liar I would say than I am not ( L is false) but in fact I AM ( L is true).

    Well, I did my best... I'll be waiting for the right answer (is there any?)

    Re: Language of logic, or Logic of language

    But:

    Alcoholics, don't drink alcohol every time

    Gamblers, don't gamble every time

    also

    Liars, don't lie every time., they may sometimes tell the truth.

    So to find the right answer, we need to know that did he lie while answering this question. But there is no information about it, so it seems impossible to find the right answer. As I said before , I think this is a vicous circle, we are waiting for the answer dear justin.
