Venus/observation

Famous quotes containing the words venus and/or observation:

“Yet have I fierce affections, and think
What Venus did with Mars.”
—William Shakespeare (1564–1616)

“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)
