Famous quotes containing the word test:

    “In my utter impotence to test the authenticity of the report of my senses, to know whether the impressions they make on me correspond with outlying objects, what difference does it make, whether Orion is up there in heaven, or some god paints the image in the firmament of the soul?”
    —Ralph Waldo Emerson (1803–1882)
