Famous quotes containing the word growth:
“That land is like an Eagle, whose young gaze
Feeds on the noontide beam, whose golden plume
Floats moveless on the storm, and in the blaze
Of sunrise gleams when Earth is wrapped in gloom;
An epitaph of glory for the tomb
Of murdered Europe may thy fame be made,
Great People! as the sands shalt thou become;
Thy growth is swift as morn, when night must fade;
The multitudinous Earth shall sleep beneath thy shade.”
—Percy Bysshe Shelley (17921822)
“Hence, the less government we have, the better,the fewer laws, and the less confided power. The antidote to this abuse of formal Government, is, the influence of private character, the growth of the Individual; the appearance of the principal to supersede the proxy; the appearance of the wise man, of whom the existing government, is, it must be owned, but a shabby imitation.”
—Ralph Waldo Emerson (18031882)
“A revolution is not the overturning of a cart, a reshuffling in the cards of state. It is a process, a swelling, a new growth in the race. If it is real, not simply a trauma, it is another ring in the tree of history, layer upon layer of invisible tissue composing the evidence of a circle.”
—Kate Millett (b. 1934)
