Famous quotes containing the words comparison and/or tables:

    “When we reflect on our past sentiments and affections, our thought is a faithful mirror, and copies its objects truly; but the colours which it employs are faint and dull, in comparison of those in which our original perceptions were clothed.”
    —David Hume (1711–1776)

    “O these encounterers, so glib of tongue,
    That give a coasting welcome ere it comes,
    And wide unclasp the tables of their thoughts
    To every ticklish reader! Set them down
    For sluttish spoils of opportunity
    And daughters of the game.”
    —William Shakespeare (1564–1616)
