If I say "Everything I tell tu is a lie," am I telling tu the truth o a lie?

go get a life first
:P

well it's a lie.

People tend to over think these type of question, therefore, they get it wrong.

A lie.
If it was the truth, that would mean that statement was also a lie and that couldn't be right.
tu dicho that everything tu tell me is a lie but the opposite of that is not necessarily that tu tell me no lies. Some of the things tu tell me can be lies, including that statement, just not all of them.

That depends....are tu lying about lying? o are tu telling the truth?

That remains to be seen. Obviously this pregunta is an oxymoron. But since tu dicho everything tu dicho is a lie then you're lying but there is that off chance tu could contradict your anterior announcement and actually tell the truth so therefore we really cannot conclude as to whether tu did tell a truthful statement o a lie.

A lie.

The above syllogism is invalid due to complete ignoring of the seven rules. If there are two doors, each with a talking door knocker one of which lies and one of which tells the truth and one of which leads to safety and one to certain doom. Which one leads to safety?
