Famous quotes containing the words primitive and/or pit:

    That primitive head
    So ambitiously vast,
    Yet so rude in its art,
    Is as easily read
    For the woes of the past
    As a clinical chart.
    Robert Frost (1874–1963)

    Violence does, in truth, recoil upon the violent, and the schemer falls into the pit which he digs for another.
