Famous quotes containing the words comparison and/or tables:
“When we reflect on our past sentiments and affections, our thought is a faithful mirror, and copies its objects truly; but the colours which it employs are faint and dull, in comparison of those in which our original perceptions were clothed.”
—David Hume (17111776)
“Hast thou named all the birds without a gun?
Loved the wood rose, and left it on its stalk?
At rich mens tables eaten bread and pulse?
Unarmed, faced danger with a heart of trust?”
—Ralph Waldo Emerson (18031882)
