Famous quotes containing the word error:
“Truth is one, but error proliferates. Man tracks it down and cuts it up into little pieces hoping to turn it into grains of truth. But the ultimate atom will always essentially be an error, a miscalculation.”
—René Daumal (1908–1944)
“In Pride, in reas’ning Pride, our error lies;
All quit their sphere, and rush into the skies.
Pride still is aiming at the blest abodes,
Men would be Angels, Angels would be Gods.”
—Alexander Pope (1688–1744)
“Men have an extraordinarily erroneous opinion of their position in nature; and the error is ineradicable.”
—W. Somerset Maugham (1874–1966)
