Here is another question I didn't get a clear answer to when the term "consistency" is applied in philosophy, logic and computer science.
Is always lying consistent since we know the statements are false? For example please assume that some person or system always makes false statements. Knowing this I could deduce everything from false statement e.g. getting the false statement that bird can't fly I would conclude that since the system or person is always lying then I just know the negation of that information is the truth.
But isn't it contradictory that a system that always tells me a lie is a consistent system? I can deduce truth and evidence from the system knowing that it is always false, so is it my interpretation that makes the notion of consistence combining the knowledge that the statements are false and therefore making false statement is indeed inconsistent and it's only applying the logic that the statements are false that makes the notion of consistency when the statement are true?
Thank you for any comments and/or answers
