The tree which moves some to tears of joy is in the eyes of others only a green thing that stands in the way. Some see nature all ridicule and deformity ... and some scarce see nature at all. But to the eyes of the man of imagination, nature is imagination itself.
(William Blake (1757-1827), British poet, painter, engraver. letter, Aug. 23, 1799. The Letters of William Blake, ed. Geoffrey Keynes (1956).)
There is in my nature, methinks, a singular yearning toward all wildness.
(Henry David Thoreau (1817-1862), U.S. philosopher, author, naturalist. A Week on the Concord and Merrimack Rivers (1849), in The Writings of Henry David Thoreau, vol. 1, p. 54, Houghton Mifflin (1906).)
