Nonsense delights us I think because it offers us language in mutation, in gestation — how much richer English is for “brillig” and “snark!” — and because it ridicules pompous, vain, and obsessive behavior.
“When I behold how black, immortal ink
Drips from my deathless pen—ah, well-away!
Why should we stop at all for what I think?
There is enough in what I chance to say.”
