'No,' said Ibid coldly. 'There's a dozen tortoise kebabs to prove him wrong. The trouble with my friend here is that he doesn't know the difference between a postulate and a metaphor of human existence. Or a hole in the ground.'
'It didn't hit it yesterday,' snapped Xeno.
'Yes, I was watching. You hardly pulled the string back. I saw you,' said Ibid.
They started to argue again.
Teppic stared into his wine mug. These men are philosophers, he thought. They had told him so. So their brains must be so big that they have room for ideas that no-one else would consider for five seconds. On the way to the tavern Xeno had explained to him, for example, why it was logically impossible to fall out of a tree.
Teppic had described the vanishing of the kingdom, but he hadn't revealed his position in it. He hadn't a lot of experience of these matters, but he had a very clear feeling that kings who hadn't got a kingdom any more were not likely to be very popular in neighbouring countries. There had been one or two like that in Ankh-Morpork - deposed royalty, who had fled their suddenly-dangerous kingdoms for Ankh's hospitable bosom carrying nothing but the clothes they stood up in and a few wagonloads of jewels. The city, of course, welcomed anyone - regardless of race, colour, class or creed - who had spending money in incredible amounts, but nevertheless the inhumation of surplus monarchs was a regular source of work for the Assassins' Guild. There was always someone back home who wanted to be certain that deposed monarchs stayed that way. It was usually a case of heir today, gone tomorrow.
'I think it got caught up in geometry,' he said, hopefully. 'I heard you were very good at geometry here,' he added, 'and perhaps you could tell me how to get back.'
'Geometry is not my forte,' said Ibid. 'As you probably know.'
'Sorry?'
'Haven't you read my Principles of Ideal Government?'
'I'm afraid not.'
'Or my Discourse on Historical Inevitability?'
'No.'
Ibid looked crestfallen. 'Oh,' he said.
'Ibid is a well-known authority on everything,' said Xeno. 'Except for geometry. And interior decorating. And elementary logic.' Ibid glared at him.
'What about you, then?' said Teppic.
Xeno drained his mug. 'I'm more into the destruct testing of axioms,' he said. 'The chap you need is Pthagonal. A very acute man with an angle.'
He was interrupted by the clatter of hooves. Several horsemen galloped with reckless speed past the tavern and on up the winding, cobbled streets of the city. They seemed very excited about something.
Ibid picked a stunned seagull out of his wine cup and laid it on the table. He was looking thoughtful.
'If the Old Kingdom has really disappeared-' he said.
'It has,' said Teppic firmly. 'It's not something you can be mistaken about, really.'
'Then that means our border is concurrent with that of Tsort,' said Ibid ponderously.
'Pardon?' said Teppic.
'There's nothing between us,' explained the philosopher.
'Oh, dear. That means we shall be forced to make war.'
'Why?'
Ibid opened his mouth, stopped, and turned to Xeno.
'Why does it mean we'll be forced to make war?' he said.
'Historical imperative,' said Xeno.
'Ah, yes. I knew it was something like that. I am afraid it is inevitable. It's a shame, but there you are.'
