Famous quotes containing the word error:
“Truth is the kind of error without which a certain species of life could not live. The value for life is ultimately decisive.”
—Friedrich Nietzsche (1844–1900)
“Error is a supposition that pleasure and pain, that intelligence, substance, life, are existent in matter. Error is neither Mind nor one of Mind’s faculties. Error is the contradiction of Truth. Error is a belief without understanding. Error is unreal because untrue. It is that which seemeth to be and is not. If error were true, its truth would be error, and we should have a self-evident absurdity—namely, erroneous truth. Thus we should continue to lose the standard of Truth.”
—Mary Baker Eddy (1821–1910)
“An error the breadth of a single hair can lead one a thousand miles astray.”
—Chinese proverb.
