Famous quotes containing the words david and/or duncan:
“Already nature is serving all those uses which science slowly derives on a much higher and grander scale to him that will be served by her. When the sunshine falls on the path of the poet, he enjoys all those pure benefits and pleasures which the arts slowly and partially realize from age to age. The winds which fan his cheek waft him the sum of that profit and happiness which their lagging inventions supply.”
—Henry David Thoreau (1817–1862)
“The only dance masters I could have were Jean-Jacques Rousseau, Walt Whitman and Nietzsche.”
—Isadora Duncan (1878–1927)
