A lie. If it was the truth, that would mean that statement was also a lie and that couldn't be right. あなた 発言しました that everything あなた tell me is a lie but the opposite of that is not necessarily that あなた tell me no lies. Some of the things あなた tell me can be lies, including that statement, just not all of them.
That remains to be seen. Obviously this 質問 is an oxymoron. But since あなた 発言しました everything あなた 発言しました is a lie then you're lying but there is that off chance あなた could contradict your 前 announcement and actually tell the truth so therefore we really cannot conclude as to whether あなた did tell a truthful statement または 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?
