Actual Error Covariance

Famous quotes containing the words actual and/or error:

“We can never safely exceed the actual facts in our narratives. Of pure invention, such as some suppose, there is no instance. To write a true work of fiction even is only to take leisure and liberty to describe some things more exactly as they are.”
—Henry David Thoreau (1817–1862)

“Literature exists at the same time in the modes of error and truth; it both betrays and obeys its own mode of being.”
—Paul Deman (1919–1983)
