Famous quotes containing the words comparison and/or tables:
“The comparison between Coleridge and Johnson is obvious in so far as each held sway chiefly by the power of his tongue. The difference between their methods is so marked that it is tempting, but also unnecessary, to judge one to be inferior to the other. Johnson was robust, combative, and concrete; Coleridge was the opposite. The contrast was perhaps in his mind when he said of Johnson: his bow-wow manner must have had a good deal to do with the effect produced.”
—Virginia Woolf (18821941)
“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)
