Person A claims person B always tells the truth.
Person B claims person B (himself) sometimes tells the truth.
Person C claims person B always lies.
Secondly, I want to solve this riddle. Who is the liar? — javi2541997
when he says he sometimes tells the truth, is he saying he's definitely not the guy who always tells the truth? — flannel jesus
B is the liar — flannel jesus
is he saying he's definitely not the guy who always tells the truth? — flannel jesus
That only leaves C as the guy who always tells the truth — flannel jesus
The rest naturally follows — flannel jesus
A sometimes tells the truth, and his statement in this riddle just happens to be a lie. Presumably one can imagine a has told the truth at some other occasion. — flannel jesus
Then B is always false and ambiguous — javi2541997
But what happens to A? — javi2541997
Among persons A, B and C one person always lies, one person always tells the truth and one person sometimes speaks the truth, hence being ambiguous.
We get the following statements:
Person A claims person B always tells the truth.
Person B claims person B (himself) sometimes tells the truth.
Person C claims person B always lies. — javi2541997
(1) Person A claims person B always tells the truth.
(2) Person B claims person B (himself) sometimes tells the truth.
(3) Person C claims person B always lies.
Assuming either one of them is the truth teller leads to contradiction, so we don't. — flannel jesus
But what happens to A then — javi2541997
B cannot be the truth-teller. — javi2541997
Nonetheless, it seems the riddle turned out with A being the ambiguous person — javi2541997
No, B is the ambiguous person given the ambiguity of the phrase "I sometimes tell the truth". — Michael
He's using unclear wording, but when he says "ambiguous person" he means "the person who sometimes tells the truth". He doesn't mean "the person whose role is ambiguous". — flannel jesus
