Famous quotes containing the word tree:

    Every tree sends its fibres forth in search of the Wild. The cities import it at any price. Men plow and sail for it. From the forest and wilderness come the tonics and barks which brace mankind.
    Henry David Thoreau (1817–1862)

    A tree the span of two arms starts from a tiny seedling.
    —Chinese proverb.

    Lao-tzu.

    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)
