Famous quotes containing the word nature:

    “How like a prodigal doth nature seem,
    When thou, for all thy gold, so common art!
    Thou teachest me to deem
    More sacredly of every human heart,
    Since each reflects in joy its scanty gleam
    Of Heaven, and could some wondrous secret show,
    Did we but pay the love we owe,
    And with a child’s undoubting wisdom look
    On all these living pages of God’s book.”
    —James Russell Lowell (1819–1891)
