Famous quotes containing the words primary and/or channel:
“Wilful sterility is, from the standpoint of the nation, from the standpoint of the human race, the one sin for which the penalty is national death, race death; a sin for which there is no atonement.... No man, no woman, can shirk the primary duties of life, whether for love of ease and pleasure, or for any other cause, and retain his or her self-respect.”
—Theodore Roosevelt (1858–1919)
“How old the world is! I walk between two eternities.... What is my fleeting existence in comparison with that decaying rock, that valley digging its channel ever deeper, that forest that is tottering and those great masses above my head about to fall? I see the marble of tombs crumbling into dust; and yet I don’t want to die!”
—Denis Diderot (1713–1784)
