Famous quotes containing the words airships, designed and/or henri:
“They’re semiotic phantoms, bits of deep cultural imagery that have split off and taken on a life of their own, like those Jules Verne airships that those old Kansas farmers were always seeing.... Semiotic ghosts. Fragments of the Mass Dream, whirling past in the wind of my passage.”
—William Gibson (b. 1948)
“As I walked on the glacis I heard the sound of a bagpipe from the soldiers’ dwellings in the rock, and was further soothed and affected by the sight of a soldier’s cat walking up a cleated plank in a high loophole designed for mus-catry, as serene as Wisdom herself, and with a gracefully waving motion of her tail, as if her ways were ways of pleasantness and all her paths were peace.”
—Henry David Thoreau (1817–1862)
“If I meet the Christian Deity, I am lost: He is a tyrant and as such, is full of ideas of vengeance; His Bible speaks of nothing but fearful punishments. I never loved Him! I could never even believe that anyone did love Him sincerely. He is devoid of pity.... He will punish me in some abominable manner.”
—Stendhal [Marie Henri Beyle] (1783–1842)
