Famous quotes containing the words security and/or kernel:
“Is a Bill of Rights a security for [religious liberty]? If there were but one sect in America, a Bill of Rights would be a small protection for liberty.... Freedom derives from a multiplicity of sects, which pervade America, and which is the best and only security for religious liberty in any society. For where there is such a variety of sects, there cannot be a majority of any one sect to oppress and persecute the rest.”
—James Madison (1751–1836)
“After night’s thunder far away had rolled
The fiery day had a kernel sweet of cold”
—Edward Thomas (1878–1917)
