Moralist: A statement is wholly truthful only if it is true and made without intended deception
A statement is a lie if it is intended to deceive or if its speaker, upon learning that the statement was misinterpreted, refrains from clarifying it
The tour guide intended to deceive the tourists when he told them that the cabin they were looking at was centuries old. Still, his statement about the cabin's age was not a lie, for if he thought that this statement had been misinterpreted, he would have tried to clarify it.
