There's something in science like the shine of the Patronus Charm, driving back all sorts of darkness and madness.

Crocker's Rules didn't give you the right to say anything offensive, but other people could say potentially offensive things to you, and it was your responsibility not to be offended. This was surprisingly hard to explain to people; many people would read the careful explanation and hear, "Crocker's Rules mean you can say offensive things to other people."

If you've been cryocrastinating, putting off signing up for cryonics "until later", don't think that you've "gotten away with it so far". Many worlds, remember? There are branched versions of you that are dying of cancer, and not signed up for cryonics, and it's too late for them to get life insurance.

My experience is that journalists report on the nearest-cliche algorithm, which is extremely uninformative because there aren't many cliches, the truth is often quite distant from any cliche, and the only thing you can infer about the actual event was that this was the closest cliche. It is simply not possible to appreciate the sheer awfulness of mainstream media reporting until someone has actually reported on you. It is so much worse than you think.

- With respect, Professor McGonagall, I'm not quite sure you understand what I'm trying to do here. - With respect, Mr. Potter, I'm quite sure I don't. Unless - this is a guess, mind - you're trying to take over the world? - No! I mean yes - well, NO! - I think i should perhaps be alarmed that you have trouble answering the question.

To confess your fallibility and then do nothing about it is not humble; it is boasting of your modesty.

Many have stood their ground and faced the darkness when it comes for them. Fewer come for the darkness and force it to face them.
