Famous quotes containing the words test and/or substance:
“Poetry is important. No less than science, it seeks a hold upon reality, and the closeness of its approach is the test of its success.”
—Babette Deutsch (1895–1982)
“What is a country without rabbits and partridges? They are among the most simple and indigenous animal products; ancient and venerable families known to antiquity as to modern times; of the very hue and substance of Nature, nearest allied to leaves and to the ground,—and to one another; it is either winged or it is legged. It is hardly as if you had seen a wild creature when a rabbit or a partridge bursts away, only a natural one, as much to be expected as rustling leaves.”
—Henry David Thoreau (1817–1862)
