Material Time Derivative

Famous quotes containing the words material, time and/or derivative:

    Man’s characteristic privilege is that the bond he accepts is not physical but moral; that is, social. He is governed not by a material environment brutally imposed on him, but by a conscience superior to his own, the superiority of which he feels. Because the greater, better part of his existence transcends the body, he escapes the body’s yoke, but is subject to that of society.
    Emile Durkheim (1858–1917)

    When I saw it I was so glad I could not speak. My eyes seemed too little to see it all.... I was a long time without speaking to my friend. To see me always looking and never speaking he thought I had lost my mind. I could not understand where all this could come from.
    —For the State of Maine, U.S. public relief program (1935-1943)

    Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some derivative old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.
    Henry David Thoreau (1817–1862)
