Famous quotes containing the word tide:

    It is said that the British Empire is very large and respectable, and that the United States are a first-rate power. We do not believe that a tide rises and falls behind every man which can float the British Empire like a chip, if he should ever harbor it in his mind.
    Henry David Thoreau (1817–1862)

    Sweet Love of youth, forgive, if I forget thee,
    While the world’s tide is bearing me along;
    Sterner desires and darker hopes beset me,
    Hopes which obscure, but cannot do thee wrong.
    Emily Brontë (1818–1848)

    And this, because the heart in thee is the heart of all; not a valve, not a wall, not an intersection is there anywhere in nature, but one blood rolls uninterruptedly an endless circulation through all men, as the water of the globe is all one sea, and, truly seen, its tide is one.
    Ralph Waldo Emerson (1803–1882)
