APANHEI UMA PÁGINA ONDE SE TIRAM ALGUMAS LIÇÕES DE MATEMÁTICA & LÓGICA
A OBRA DE LEWIS CARROLL É TODA ELA UMA FÓRMULA TRANSFIGURADA EM SONHO.
Conselhos de uma Lagarta
A Lagarta Azul
Alice com o pescoço comprido
Do ponto de vista formal, a Pomba tinha razão:
As serpentes (s) têm pescoço comprido; Alice (a) também tinha o pescoço comprido, portanto era uma serpente (s).
No entanto, Alice (a) é uma rapariga (r), mas as raparigas (r) comem ovos, tal como as serpentes (s), portanto por subordinação, Alice não é uma serpente (s>r>a).
Neste pequeno episódio podemos ver como o professor de lógica Lewis Carroll contaminou, com questões lógicas, a literatura infantil que escreveu.
CHAPTER 2: The Garden of Live Flowers
`I should see the garden far better,' said Alice to herself, `if I could get to the top of that hill: and here's a path that leads straight to it--at least, no, it doesn't do that--' (after going a few yards along the path, and turning several sharp corners), `but I suppose it will at last. But how curiously it twists! It's more like a corkscrew than a path! Well, THIS turn goes to the hill, I suppose--no, it doesn't! This goes straight back to the house! Well then, I'll try it the other way.'
And so she did: wandering up and down, and trying turn after turn, but always coming back to the house, do what she would. Indeed, once, when she turned a corner rather more quickly than usual, she ran against it before she could stop herself.
`It's no use talking about it,' Alice said, looking up at the house and pretending it was arguing with her. `I'm NOT going in again yet. I know I should have to get through the Looking-glass again--back into the old room--and there'd be an end of all my adventures!'
So, resolutely turning her back upon the house, she set out once more down the path, determined to keep straight on till she got to the hill. For a few minutes all went on well, and she was just saying, `I really SHALL do it this time--' when the path gave a sudden twist and shook itself (as she described it afterwards), and the next moment she found herself actually walking in at the door.
'Oh, it's too bad!' she cried. `I never saw such a house for getting in the way! Never!'
However, there was the hill full in sight, so there was nothing to be done but start again. This time she came upon a large flower-bed, with a border of daisies, and a willow-tree growing in the middle.
`O Tiger-lily,' said Alice, addressing herself to one that was waving gracefully about in the wind, `I WISH you could talk!'
