Famous quotes containing the word climate:
“Ghosts, we hope, may be always with usthat is, never too far out of the reach of fancy. On the whole, it would seem they adapt themselves well, perhaps better than we do, to changing world conditionsthey enlarge their domain, shift their hold on our nerves, and, dispossessed of one habitat, set up house in another. The universal battiness of our century looks like providing them with a propitious climate ...”
—Elizabeth Bowen (18991973)
“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (18891974)
“The question of place and climate is most closely related to the question of nutrition. Nobody is free to live everywhere; and whoever has to solve great problems that challenge all his strength actually has a very restricted choice in this matter. The influence of climate on our metabolism, its retardation, its acceleration, goes so far that a mistaken choice of place and climate can not only estrange a man from his task but can actually keep it from him: he never gets to see it.”
—Friedrich Nietzsche (18441900)
