Famous quotes containing the word tree:

    A revolution is not the overturning of a cart, a reshuffling in the cards of state. It is a process, a swelling, a new growth in the race. If it is real, not simply a trauma, it is another ring in the tree of history, layer upon layer of invisible tissue composing the evidence of a circle.
    Kate Millett (b. 1934)

    Here is a hero who did nothing but shake the tree as soon as the fruit was ripe. Does this seem to be too small a thing to you? Then take a good look at the tree he shook.
    Friedrich Nietzsche (1844–1900)

    The tree of Knowledge is a Tree of Knowledge of good and evil.
    Henry David Thoreau (1817–1862)
