Famous quotes containing the words physical, appearance and/or inorganic:
“How many young hearts have revealed the fact that what they had been trained to imagine the highest earthly felicity was but the beginning of care, disappointment, and sorrow, and often led to the extremity of mental and physical suffering.”
—Catherine E. Beecher (1800–1878)
“This mesa plain had an appearance of great antiquity, and of incompleteness; as if, with all the materials for world-making assembled, the Creator had desisted, gone away and left everything on the point of being brought together, on the eve of being arranged into mountain, plain, plateau. The country was still waiting to be made into a landscape.”
—Willa Cather (1873–1947)
“Man, unlike anything organic or inorganic in the universe, grows beyond his work, walks up the stairs of his concepts, emerges ahead of his accomplishments.”
—John Steinbeck (1902–1968)
