I know it's a very human thing to say 'Is there anything I can do', but in this case I would only entertain offers from very high-end experts in brain chemistry.

Granny bit her lip. She was never quite certain about children, thinking of them-when she thought about them at all-as coming somewhere between animals and people. She understood babies. You put milk in one end and kept the other as clean as possible. Adults were even easier, because they did the feeding and cleaning themselves. But in between was a world of experience that she had never really inquired about. As far as she was aware, you just tried to stop them catching anything fatal and hoped that it would all turn out all right.

There's a saying that all roads lead to Ankh-Morpork. And it's wrong. All roads lead away from Ankh-Morpork, but sometimes people just walk along them the wrong way.

If you have to look along the shaft of an arrow from the wrong end, if a man has you entirely at his mercy, then hope like hell that man is an evil man. Because the evil like power... they will talk, they will gloat. So hope like hell your captor is an evil man. A good man will kill you with hardly a word.

Education had been easy. Learning things had been harder.

Humans! They lived in a world where the grass continued to be green and the sun rose every day and flowers regularly turned into fruit, and what impressed them? Weeping statues. And wine made out of water! A mere quantum-mechanistic tunnel effect, that'd happen anyway if you were prepared to wait zillions of years. As if the turning of sunlight into wine, by means of vines and grapes and time and enzymes, wasn't a thousand times more impressive and happened all the time.

Wizards don't believe in gods in the same way that most people don't find it necessary to believe in, say, tables. They know they're there, they know they're there for a purpose, they'd probably agree that they have a place in a well-organised universe, but they wouldn't see the point of believing, of going around saying "O great table, without whom we are as naught." Anyway, either the gods are there whether you believe in them or not, or exist only as a function of the belief, so either way you might as well ignore the whole business and, as it were, eat off your knees.
