About this business of all of us being just manifestations of PZ – Russell Glasser wittily quoted an apt bit of Through the Looking Glass by Lewis Carroll.

Here she checked herself in some alarm, at hearing something that sounded to her like the puffing of a large steam-engine in the wood near them, though she feared it was more likely to be a wild beast. ‘Are there any lions or tigers about here?’ she asked timidly.

‘It’s only the Red King snoring,’ said Tweedledee.

‘Come and look at him!’ the brothers cried, and they each took one of Alice’s hands, and led her up to where the King was sleeping.

‘Isn’t he a LOVELY sight?’ said Tweedledum.

Alice couldn’t say honestly that he was. He had a tall red night-cap on, with a tassel, and he was lying crumpled up into a sort of untidy heap, and snoring loud—’fit to snore his head off!’ as Tweedledum remarked.

‘I’m afraid he’ll catch cold with lying on the damp grass,’ said Alice, who was a very thoughtful little girl.

‘He’s dreaming now,’ said Tweedledee: ‘and what do you think he’s dreaming about?’

Alice said ‘Nobody can guess that.’

‘Why, about YOU!’ Tweedledee exclaimed, clapping his hands triumphantly. ‘And if he left off dreaming about you, where do you suppose you’d be?’

‘Where I am now, of course,’ said Alice.

‘Not you!’ Tweedledee retorted contemptuously. ‘You’d be nowhere. Why, you’re only a sort of thing in his dream!’

‘If that there King was to wake,’ added Tweedledum, ‘you’d go out—bang!—just like a candle!’

‘I shouldn’t!’ Alice exclaimed indignantly. ‘Besides, if I’M only a sort of thing in his dream, what are YOU, I should like to know?’

A profound question, I’m sure you’ll agree.
