Famous quotes containing the words thought and/or experiments:
“I thought of all that worked dark pits
Of war, and died
Digging the rock where Death reputes
Peace lies indeed.”
—Wilfred Owen (1893–1918)
“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)
