Famous quotes containing the words sharp and/or echo:
“Sorrow for a husband is like a pain in the elbow, sharp and short.”
—English proverb, collected in Thomas Fuller, Gnomologia, no. 4321 (1732)
“The moralist and the revolutionary are constantly undermining one another. Marx exploded a hundred tons of dynamite beneath the moralist position, and we are still living in the echo of that tremendous crash. But already, somewhere or other, the sappers are at work and fresh dynamite is being tamped in place to blow Marx at the moon. Then Marx, or somebody like him, will come back with yet more dynamite, and so the process continues, to an end we cannot foresee.”
—George Orwell (1903–1950)
