Color Perception

Famous quotes containing the words color and/or perception:

    African rights and liberty is a subject that ought to fire the breast of every free man of color in these United States, and excite in his bosom a lively, deep, decided and heart-felt interest.
    Maria Stewart (1803–1879)

    The most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.
    Marcus Tullius Cicero (106–43 B.C.)
