Famous quotes containing the words errors in, errors, sample and/or surveys:
“There are two equal and opposite errors into which our race can fall about the devils. One is to disbelieve in their existence. The other is to believe, and to feel an excessive and unhealthy interest in them. They themselves are equally pleased by both errors and hail a materialist or a magician with the same delight.”
—C.S. (Clive Staples)
“The errors of the observer come from the qualities of the human mind.”
—Johann Wolfgang Von Goethe (1749–1832)
“All that a city will ever allow you is an angle on it—an oblique, indirect sample of what it contains, or what passes through it; a point of view.”
—Peter Conrad (b. 1948)
“Linnæus, setting out for Lapland, surveys his “comb” and “spare shirt,” “leathern breeches” and “gauze cap to keep off gnats,” with as much complacency as Bonaparte a park of artillery for the Russian campaign. The quiet bravery of the man is admirable.”
—Henry David Thoreau (1817–1862)
