Singularitarians are the munchkins of the real world. We just ignore all the usual dungeons and head straight for the cycle of infinite wish spells.

I ask the fundamental question of rationality: Why do you believe what you believe? What do you think you know and how do you think you know it?

You couldn't changed history. But you could get it right to start with. Do something differently the FIRST time around. This whole business with seeking Slytherin's secrets... seemed an awful lot like the sort of thing where, years later, you would look back and say, 'And THAT was where it all started to go wrong.' And he would wish desperately for the ability to fall back through time and make a different choice. Wish granted. Now what?

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

Trying and getting hurt can't possibly be worse for you than being... stuck.

When you are older, you will learn that the first and foremost thing which any ordinary person does is nothing.

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