Famous quotes containing the words spectral and/or line:
“How does one kill fear, I wonder? How do you shoot a spectre through the heart, slash off its spectral head, take it by its spectral throat?”
—Joseph Conrad (1857–1924)
“If you’re anxious for to shine in the high esthetic line as a man
of culture rare,
You must get up all the germs of the transcendental terms, and plant
them everywhere.
You must lie upon the daisies and discourse in novel phrases of your
complicated state of mind,
The meaning doesn’t matter if it’s only idle chatter of a
transcendental kind.”
—Sir William Schwenck Gilbert (1836–1911)
