Famous quotes containing the word security:
“If we could have any security against moods! If the profoundest prophet could be holden to his words, and the hearer who is ready to sell all and join the crusade, could have any certificate that to-morrow his prophet shall not unsay his testimony!”
—Ralph Waldo Emerson (1803–1882)
“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)
“To have in general but little feeling, seems to be the only security against feeling too much on any particular occasion.”
—George Eliot [Mary Ann (or Marian)
