Famous quotes containing the word tide:

    Ktaadn ... is an Indian word signifying highest land,... very few, even among backwoodsmen and hunters, have ever climbed it, and it will be a long time before the tide of fashionable travel sets that way.
    Henry David Thoreau (1817–1862)

    The only mode of obtaining an answer to these questions of the senses is to forego all low curiosity, and, accepting the tide of being which floats us into the secret of nature, work and live, work and live, and all unawares the advancing soul has built and forged for itself a new condition, and the question and the answer are one.
    Ralph Waldo Emerson (1803–1882)

    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)
