Famous quotes containing the words council and/or diamond:

    Parental attitudes have greater correlation with pupil achievement than material home circumstances or variations in school and classroom organization, instructional materials, and particular teaching practices.
    —Children and Their Primary Schools, vol. 1, ch. 3, Central Advisory Council for Education, London (1967)

    A poet who makes use of a worse word instead of a better, because the former fits the rhyme or the measure, though it weakens the sense, is like a jeweller, who cuts a diamond into a brilliant, and diminishes the weight to make it shine more.
    Horace Walpole (1717–1797)
