Famous quotes containing the word science:

    “Oh, what does science not conceal today! How much, at any rate, is it meant to conceal!”
    —Friedrich Nietzsche (1844–1900)

    “The natural historian is not a fisherman who prays for cloudy days and good luck merely; but as fishing has been styled “a contemplative man’s recreation,” introducing him profitably to woods and water, so the fruit of the naturalist’s observations is not in new genera or species, but in new contemplations still, and science is only a more contemplative man’s recreation.”
    —Henry David Thoreau (1817–1862)

    “Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.”
    —Jules Henri Poincare (1854–1912)
