Famous quotes containing the word safety:
“Firm, united, let us be,
Rallying round our Liberty;
As a band of brothers joined,
Peace and safety we shall find.”

“There is always safety in valor.”
—Ralph Waldo Emerson (1803–1882)
“The Declaration [of Independence] was not a protest against government, but against the excess of government. It prescribed the proper role of government, to secure the rights of individuals and to effect their safety and happiness. In modern society, no individual can do this alone. So government is not a necessary evil but a necessary good.”
—Gerald R. Ford (b. 1913)
