Famous quotes containing the word tide:

    “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)
