Famous quotes containing the words fundamental and/or plane:

    “I believe the declaration that “all men are created equal” is the great fundamental principle upon which our free institutions rest.”
    —Abraham Lincoln (1809–1865)

    “Have you ever been up in your plane at night, alone, somewhere, 20,000 feet above the ocean?... Did you ever hear music up there?... It’s the music a man’s spirit sings to his heart, when the earth’s far away and there isn’t any more fear. It’s the high, fine, beautiful sound of an earth-bound creature who grew wings and flew up high and looked straight into the face of the future. And caught, just for an instant, the unbelievable vision of a free man in a free world.”
    —Dalton Trumbo (1905–1976)
