Famous quotes containing the words popular and/or culture:
“The man of large and conspicuous public service in civil life must be content without the Presidency. Still more, the availability of a popular man in a doubtful State will secure him the prize in a close contest against the first statesman of the country whose State is safe.”
—Rutherford Birchard Hayes (1822–1893)
“To be a Negro is to participate in a culture of poverty and fear that goes far deeper than any law for or against discrimination.... After the racist statutes are all struck down, after legal equality has been achieved in the schools and in the courts, there remains the profound institutionalized and abiding wrong that white America has worked on the Negro for so long.”
—Michael Harrington (1928–1989)
