Famous quotes containing the words reducing and/or atmosphere:
“Single acts of tyranny may be ascribed to the accidental opinion of a day; but a series of oppressions ... too plainly prove a deliberate, systematical plan of reducing us to slavery.”
—Thomas Jefferson (1743–1826)
“And so I look on those sentiments which make the glory of the human being, love, humility, faith, as being also the intimacy of Divinity in the atoms; and, that, as soon as the man is right, assurances and previsions emanate from the interior of his body and his mind; as, when flowers reach their ripeness, incence exhales from them, and, as a beautiful atmosphere is generated from the planet by the averaged emanations from all its rocks and soils.”
—Ralph Waldo Emerson (1803–1882)
