Famous quotes containing the words time, variance and/or authority:

    It would seem that man was born a slave, and that slavery is his natural condition. At the same time nothing on earth can stop man from feeling himself born for liberty. Never, whatever may happen, can he accept servitude; for he is a thinking creature.
    Simone Weil (1909–1943)

    There is an untroubled harmony in everything, a full consonance in nature; only in our illusory freedom do we feel at variance with it.
    Fyodor Tyutchev (1803–1873)

    I am still a learner, not a teacher, feeding somewhat omnivorously, browsing both stalk and leaves; but I shall perhaps be enabled to speak with more precision and authority by and by,—if philosophy and sentiment are not buried under a multitude of details.
    Henry David Thoreau (1817–1862)
