Famous quotes containing the word structure:

    What is the structure of government that will best guard against the precipitate counsels and factious combinations for unjust purposes, without a sacrifice of the fundamental principle of republicanism?
    James Madison (1751–1836)

    A structure becomes architectural, and not sculptural, when its elements no longer have their justification in nature.
    Guillaume Apollinaire (1880–1918)

    For the structure that we raise,
    Time is with materials filled;
    Our to-days and yesterdays
    Are the blocks with which we build.
    Henry Wadsworth Longfellow (1809–1882)
