Liar paradox - If this sentence were true, then what it says would be the truth, implying that it is false which is a contradiction, so if it were false then it is false that this sentence is false, hence it is true which is also a contradiction.

It is clearly not true. And that untrue meaning can be conveyed, whether in blatant lies, exaggeration, sarcasm, or other devices utilizing untrueness. That's not even counting questions and ambivalence.

I feel that you don't really know what you are talking about, but just in case,

Would you then say that the equivalent to "You are 100 meters tall" is "It is false that you are 100 meters tall"?

Not really.

Try this then. Someone wakes up with a terrible hangover from a rough night. Another person make a sarcastic comment...

  • "Hey beauty queen."

  • "You look a million bucks."

  • "Saving the world one shot at a time."

All of these examples are clearly not meant to be true.

Sarcasm, too good to be true.

Again I say, you are talking about sentences with context, whereas "This sentence is false" lacks any.

Even without context no one can be 100 meters tall.

Even without context "You look a million bucks" could be a compliment or not.

Context was not mentioned in post. Sentences can be false and/or wrong.

Even without context no one can be 100 meters tall.

Completely irrelevant, because even statements which might not be true still assume their own truthfulness. You are saying that the sentence would instead mean "It is false that you are 100 meters tall," so the appropriate response to that question would be affirmative, which is extremely illogical.

Context was not mentioned in post. Sentences can be false and/or wrong.

Because they assume their own truthfulness. Tell me, again, how "It is true that you are you are 100 meters tall" is different from "you are 100 meters tall"? Are you saying that instead it should be "It is NOT true that you are 100 meters tall?"

Then I guess this statement is true:

You know everything.

[–]JoJo 2 insightful - 2 fun2 insightful - 1 fun3 insightful - 2 fun -  (0 children)

No, that statement is false, but it is false because it presumes its truthfulness, because if it didn't, only then could you say that it is false, do you get it?
