Observation Wheels

Famous quotes containing the words observation and/or wheels:

“There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.”
—Denis Diderot (1713–1784)

“A cruel story runs on wheels, and every hand oils the wheels as they run.”
—Ouida [Marie Louise De La Ramée] (1839–1908)
