Famous quotes containing the word observation:
“I know not anything more pleasant, or more instructive, than to compare experience with expectation, or to register from time to time the difference between idea and reality. It is by this kind of observation that we grow daily less liable to be disappointed.”
—Samuel Johnson (1709–1784)
“Morality without religion is only a kind of dead reckoning—an endeavor to find our place on a cloudy sea by measuring the distance we have run, but without any observation of the heavenly bodies.”
—Henry Wadsworth Longfellow (1807–1882)
“The Artist is he who detects and applies the law from observation of the works of Genius, whether of man or Nature. The Artisan is he who merely applies the rules which others have detected.”
—Henry David Thoreau (1817–1862)
