Famous quotes containing the words nervous system, nervous and/or system:
“A car can massage organs which no masseur can reach. It is the one remedy for the disorders of the great sympathetic nervous system.”
—Jean Cocteau (1889–1963)
“It is a bore, I admit, to be past seventy, for you are left for execution, and are daily expecting the death-warrant; but ... it is not anything very capital we quit. We are, at the close of life, only hurried away from stomach-aches, pains in the joints, from sleepless nights and unamusing days, from weakness, ugliness, and nervous tremors; but we shall all meet again in another planet, cured of all our defects.”
—Sydney Smith (1771–1845)
“Authority is the spiritual dimension of power because it depends upon faith in a system of meaning that decrees the necessity of the hierarchical order and so provides for the unity of imperative control.”
—Shoshana Zuboff (b. 1951)
