There was a town where everything was forbidden.

Now, since the only thing that wasn’t forbidden was the game tip-cat, the town’s subjects used to assemble on meadows behind the town and spend the day there playing tip-cat.

And as the laws forbidding things had been introduced one at a time and always with good reason, no one found any cause for complaint or had any trouble getting used to them.

Years passed. One day the constables saw that there was no longer any reason why everything should be forbidden and they sent messengers to inform their subjects that they could do whatever they wanted.

The messengers went to those places where the subjects were wont to assemble.

‘Hear ye, hear ye,’ they announced, ‘nothing is forbidden any more.’

The people went on playing tip-cat.

‘Understand?’ the messengers insisted. ‘You are free to do what you want.’

‘Good,’ replied the subjects. ‘We’re playing tip-cat.’

The messengers busily reminded them of the many wonderful and useful occupations they had once engaged in and could now engage in once again. But the subjects wouldn’t listen and just went on playing, stroke after stroke, without even stopping for a breather.

Seeing that their efforts were in vain, the messengers went to tell the constables.

‘Easy,’ the constables said. ‘Let’s forbid the game of tip-cat.’

That was when the people rebelled and killed the lot of them.

Then without wasting time, they got back to playing tip-cat.

In fact the problem Leopardi is facing is speculative and metaphysical, a problem in the history of philosophy from Parmenides to Descartes and Kant: the relationship between the idea of infinity as absolute space and absolute time, and our empirical knowledge of space and time.
