"You know the technical difference between an 'art' and a 'science' in the Society, don't you? If you hit it with an axe, and it goes away, it's an art. If you hit it with an axe, and it's still there, it's a science.
For instance, if you hit a bard with an axe, the ambulance will come and take him away. Therefore, music is an art. But if you hit a barrel of mead with an axe, it spills all over the floor but it's still there. Therefore, brewing is a science."
