Famous quotes containing the words security and/or kernel:

    “Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.”
    —Johan Huizinga (1872–1945)

    “After night’s thunder far away had rolled
    The fiery day had a kernel sweet of cold”
    —Edward Thomas (1878–1917)
