Scaling and Root Planing/physical Principles

Famous quotes containing the words root, physical and/or principles:

    Black creeps from root to root,
    each leaf
    cuts another leaf on the grass,
    shadow seeks shadow,
    then both leaf
    and leaf-shadow are lost.
    Hilda Doolittle (1886–1961)

    Nationality is the miracle of political independence; race is the principle of physical analogy.
    Benjamin Disraeli (1804–1881)

    Every political system is an accumulation of habits, customs, prejudices, and principles that have survived a long process of trial and error and of ceaseless response to changing circumstances. If the system works well on the whole, it is a lucky accident—the luckiest, indeed, that can befall a society.
    Edward C. Banfield (b. 1916)
