Modus ponens

The squirrel was demonstrating how to build up all logic gates just from NAND but the visiting pair of jackdaws wanted to move on and discuss Shelah’s classification of countable first-order theories. We did that for long enough (35 seconds) to see that none of us had any idea what we were talking about. The husband jackdaw noted that darkness was approaching and the wife jackdaw pointed out that negations, such as darkness, can’t ‘approach’ or in fact ‘do’ anything.

Squirrel Larder Trek

The squirrel of I Ching, incongruous and slow
(for a squirrel (from the cold)) walks briskly on the snow.

‘A grey squirrel in a snow bank,’ says Lord Flea.
‘If he cannot find his acorns I will freeze.’

‘If he finds his cache, will he let us cage a smidgen?’

The snow crust breaks. The I Ching squirrel chutes through
to his larder stashed with acorns. He eats two.
