Famous quotes containing the words sharp and/or echo:
“There are moods in which we court suffering, in the hope that here, at least, we shall find reality, sharp peaks and edges of truth. But it turns out to be scene-painting and counterfeit. The only thing grief has taught me, is to know how shallow it is.”
—Ralph Waldo Emerson (1803–1882)
“Art for art’s sake? I should think so, and more so than ever at the present time. It is the one orderly product which our middling race has produced. It is the cry of a thousand sentinels, the echo from a thousand labyrinths, it is the lighthouse which cannot be hidden ... it is the best evidence we can have of our dignity.”
—E.M. (Edward Morgan)
