Famous quotes containing the words scale and/or moments:
“I by no means rank poetry high in the scale of intelligence—this may look like affectation but it is my real opinion. It is the lava of the imagination whose eruption prevents an earthquake.”
—George Gordon Noel Byron (1788–1824)
“Science with its retorts would have put me to sleep; it was the opportunity to be ignorant that I improved. It suggested to me that there was something to be seen if one had eyes. It made a believer of me more than before. I believed that the woods were not tenantless, but choke-full of honest spirits as good as myself any day,—not an empty chamber, in which chemistry was left to work alone, but an inhabited house,—and for a few moments I enjoyed fellowship with them.”
—Henry David Thoreau (1817–1862)
