Famous quotes containing the words magic and/or number:
“Without, the frost, the blinding snow,
The storm-wind’s moody madness—
Within, the firelight’s ruddy glow,
And childhood’s nest of gladness.
The magic words shall hold thee fast:
Thou shalt not heed the raving blast.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“I will not adopt that ungenerous and impolitic custom so common with novel writers, of degrading by their contemptuous censure the very performances, to the number of which they are themselves adding—joining with their greatest enemies in bestowing the harshest epithets on such works, and scarcely ever permitting them to be read by their own heroine, who, if she accidentally take up a novel, is sure to turn over its insipid leaves with disgust.”
—Jane Austen (1775–1817)
