Famous quotes containing the word error:
“When we do not know the truth of a thing, it is of advantage that there should exist a common error which determines the mind of man.... For the chief malady of man is restless curiosity about things which he cannot understand; and it is not so bad for him to be in error as to be curious to no purpose.”
—Blaise Pascal (1623–1662)
“Mistakes are made on two counts: an argument is either based on error or incorrectly developed.”
—Thomas Aquinas (c. 1225–1274)
“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)
