Famous quotes containing the words central and/or architecture:
“In inner-party politics, these methods lead, as we shall yet see, to this: the party organization substitutes itself for the party, the central committee substitutes itself for the organization, and, finally, a “dictator” substitutes himself for the central committee.”
—Leon Trotsky (1879–1940)
“And when his hours are numbered, and the world
Is all his own, retiring, as he were not,
Leaves, when the sun appears, astonished Art
To mimic in slow structures, stone by stone,
Built in an age, the mad wind’s night-work,
The frolic architecture of the snow.”
—Ralph Waldo Emerson (1803–1882)
