Famous quotes containing the words sense, plan and/or act:

    Fishermen, hunters, woodchoppers, and others, spending their lives in the fields and woods, in a peculiar sense a part of Nature themselves, are often in a more favorable mood for observing her, in the intervals of their pursuits, than philosophers or poets even, who approach her with expectation. She is not afraid to exhibit herself to them.
    Henry David Thoreau (1817–1862)

    Who is the happy Warrior? Who is he
    That every man in arms should wish to be?
    It is the generous spirit, who, when brought
    Among the tasks of real life, hath wrought
    Upon the plan that pleased his boyish thought:
    Whose high endeavors are an inward light
    That makes the path before him always bright:
    Who, with a natural instinct to discern
    What knowledge can perform, is diligent to learn;
    And in himself posses his own desire;
    William Wordsworth (1770–1850)

    I look on trade and every mechanical craft as education also. But let me discriminate what is precious herein. There is in each of these works an act of invention, an intellectual step, or short series of steps taken; that act or step is the spiritual act; all the rest is mere repetition of the same a thousand times.
    Ralph Waldo Emerson (1803–1882)
