Air Proving Ground

Famous quotes containing the words air, proving and/or ground:

    Just as we are learning to value and conserve the air we breathe, the water we drink, the energy we use, we must learn to value and conserve our capacity for nurture. Otherwise, in the name of human potential we will slowly but surely erode the source of our humanity.
    Elaine Heffner (20th century)

    Indeed, the best books have a use, like sticks and stones, which is above or beside their design, not anticipated in the preface, not concluded in the appendix. Even Virgil’s poetry serves a very different use to me today from what it did to his contemporaries. It has often an acquired and accidental value merely, proving that man is still man in the world.
    Henry David Thoreau (1817–1862)

    When the ground was partially bare of snow, and a few warm days had dried its surface somewhat, it was pleasant to compare the first tender signs of the infant year just peeping forth with the stately beauty of the withered vegetation which had withstood the winter ... decent weeds, at least, which widowed Nature wears.
    Henry David Thoreau (1817–1862)
