(Henry David Thoreau (1817-1862), U.S. philosopher, author, naturalist. "Life Without Principle" (1863), in The Writings of Henry David Thoreau, vol. 4, p. 480, Houghton Mifflin (1906).)
Their errors have been weighed and found to have been dust in the balance; if their sins were as scarlet, they are now white as snow: they have been washed in the blood of the mediator and the redeemer, Time.
(Percy Bysshe Shelley (1792-1822), British poet. A Defence of Poetry (written 1821, publ. 1840).
