"I love to think of nature as an unlimited broadcasting station, through which God speaks to us every hour, if we only will tune in."    George Washington Carver

"Man must go back to nature for information."    Thomas Paine

"Nature does not complete things. She is chaotic. Man must finish, and he does so by making a garden and
 building a wall."    Robert Frost

"Nature encourages no looseness, pardons no errors."    Ralph Waldo Emerson

         All finite things reveal infinitude:
         The mountain within its singular bright shade
         Like the blue shine on freshly frozen snow,
         The after-light upon ice-burdened pines;
         Odor of basswood upon a mountain slope,
         A scene beloved of bees;
         Silence of water above a sunken tree:
         The pure serene of memory of one man,--
         A ripple widening from a single stone
         Winding around the waters of the world.     Theodore Roethke

"A morning-glory at my window satisfies me more than the metaphysics of books."    Walt Whitman

"Perhaps the truth depends on a walk around the lake."    Wallace Stevens
