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)
“Happiness is peace after strife, the overcoming of difficulties, the feeling of security and well-being. The only really happy folk are married women and single men.”
—H.L. (Henry Lewis)
“It is hard for those who have never known persecution,
And who have never known a Christian,
To believe these tales of Christian persecution.
It is hard for those who live near a Bank
To doubt the security of their money.”
—T.S. (Thomas Stearns)
