I think I have already quoted this excerpt from Sylvie and Bruno, but I`m quoting again, as I have something to add...
"And, when ninety per cent of us are lunatics, /.../ the asylums will be put to their proper use."
"And that is...?" the pompous man gravely enquired.
"To shelter the sane!" said Arthur. "We shall bar ourselves in. The lunatics will have it all their own way, outside. They`ll do it a little queerly, no doubt. Railway-collisions will be always happening; steamers always blowing up; most of the towns will be burnt down; most of the ships sunk..."
"And most of the men killed!" murmured the pompous man, who was evidently hopelessly bewildered.
"Certainly," Arthur assented. "Till at last there will be fewer lunatics than sane men. Then we come out; they go in; and things return to their normal condition!"
Lewis Carroll
Poor Arthur was wrong. First of all, the sane feed and tend lunatics in asylums and at large, but lunatics won`t bother to feed the sane, or other lunatics, for that matter.
But the important thing is, there are no asylums left for the sane to take shelter. With psychos having all their own way everywhere, there`s no longer any place left for the sane to flee to...
Doomed, ain`t we?
