Mountain System

Famous quotes containing the words mountain and/or system:

    There, on the mountain and the sky,
    On all the tragic scene they stare.
    One asks for mournful melodies;
    Accomplished fingers begin to play.
    Their eyes mid many wrinkles, their eyes,
    Their ancient, glittering eyes, are gay.
    William Butler Yeats (1865–1939)

    Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.
    Rudolf Carnap (1891–1970)
