Famous quotes containing the words principal and/or guest:
“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)
“Time is like a fashionable host,
That slightly shakes his parting guest by the hand,
And with his arms outstretched, as he would fly,
Grasps in the comer: the welcome ever smiles,
And farewell goes out sighing.”
—William Shakespeare (1564–1616)
