Famous quotes containing the words observation and/or towers:
“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 city on whom plenty held full hand,
For riches strewed herself even in her streets;
Whose towers bore heads so high they kissed the clouds,
And strangers ne’er beheld but wondered at.”
—William Shakespeare (1564–1616)
