What is pervade?

Famous quotes containing the word pervade:

    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)

    Sincerity is impossible, unless it pervade the whole being, and the pretence of it saps the very foundation of character.
    James Russell Lowell (1819–1891)
