Famous quotes containing the word security:
“The horror of class stratification, racism, and prejudice is that some people begin to believe that the security of their families and communities depends on the oppression of others, that for some to have good lives there must be others whose lives are truncated and brutal.”
—Dorothy Allison (b. 1949)
“It seems to me that our three basic needs, for food and security and love, are so mixed and mingled and entwined that we cannot straightly think of one without the others. So it happens that when I write of hunger, I am really writing about love and the hunger for it, and warmth and the love of it and the hunger for it ... and then the warmth and richness and fine reality of hunger satisfied ... and it is all one.”
—M.F.K. Fisher (b. 1908)
“There is one safeguard known generally to the wise, which is an advantage and security to all, but especially to democracies as against despots. What is it? Distrust.”
—Demosthenes (c. 384–322 B.C.)
