Famous quotes containing the words correlated and/or emanations:
“...care and labor are as much correlated to human existence as shadow is to light ...”
—Harriet Beecher Stowe (1811–1896)
“No man can tell but he that loves his children, how many delicious accents make a man’s heart dance in the pretty conversation of those dear pledges; their childishness, their stammering, their little angers, their innocence, their imperfections, their necessities, are so many little emanations of joy and comfort to him that delights in their persons and society.”
—Jeremy Taylor (1613–1667)
