Famous quotes containing the words single and/or observation:
“A single monk carries his own bucket of water; two monks carry their bucket of water together; but when there are three monks, there is no water at all.”
—Chinese proverb.
“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 (17131784)
