Gradually, at various points in our childhoods, we discover different forms of conviction. There's the rock-hard certainty of personal experience ("I put my finger in the fire and it hurt,"), which is probably the earliest kind we learn. Then there's the logically convincing, which we probably come to first through maths, in the context of Pythagoras's theorem or something similar, and which, if we first encounter it at exactly the right moment, bursts on our minds like sunrise with the whole universe playing a great chord of C Major.

If a witch needs something, another witch will give it to her. If there is war to be fought, we don't consider cost one of the factors in deciding whether or not it is right to fight. Nor do we have any notion of honor. An insult to a bear is a deadly thing. To us...inconceivable. How could you insult a witch? What would it matter if you did?

A story, to me, has a particular sprite, like the angel of the spirit of that story - and it's my job to attend to what it wants to do.
