Famous quotes containing the words embodied, energy, common and/or materials:
“I have never had a feeling politically that did not spring from the sentiments embodied in the Declaration of Independence.”
—Abraham Lincoln (1809–1865)
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“For we brought nothing into this world, and it is certain we can carry nothing out.”
—Bible: New Testament St. Paul, in 1 Timothy, 6:7.
The words also appear in the Book of Common Prayer, “Burial of the Dead.”
“Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.”
—Jane Jacobs (b. 1916)
