I don't know what you think I'm confused about, if you elaborated on that, it would be helpful. I do know that I'm confused about the current events in the story. I don't know wether Quirrel lies, I just noted that your explanation doesn't make sense to me because it relies on Quirrel telling the truth, something we shouldn't take for granted, in my opinion. I can't offer a better explanation, though.
It doesn't rely on Quirrel telling the truth, it concludes that something (which Quirrel happened to say) is true.
This turns out to be an important distinction, at least in my own life. Trying to decide a priori whether someone is lying almost never works for me. (Paul Ekman, I'm not.) The answer always turns out to be "maybe," and I frequently end up biased by whether I like the person, whether I've caught them lying in the past, etc.
It works better for me to decide what I think is or might be true, regardless of who said it.
Q1: Did Quirrel try...
- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
Spoiler policy as suggested by Unnamed and approved by Eliezer, me, and at least three other upmodders:
It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
