> The first sentence in this essay is a lie. There is something odd about saying so, as has been known since ancient times. To see why, remember that all lies are untrue.<p>I always have trouble with paradoxes because I find some probably-unrelated issue to get fixated on and then can't proceed with the author. For example, <i>are</i> all lies untrue? What if my wife didn't feel like joining a party, but I lie to the host and say it's because she got into a car accident. However, unbeknownst to me, she actually did get into a car accident that would have prevented her attendance even if she wanted to. The lie is true, but it's still a lie, right?<p>I think issues like this are resolvable, but require iteration with the person setting up the paradox. Since I can't get that from books/articles I tend to only make progress on these topics during discussions.
