Famous quotes containing the word books:
“All books are either dreams or swords,
You can cut, or you can drug, with words.”
—Amy Lowell (1874–1925)
“Old books that have ceased to be of service should no more be abandoned than should old friends who have ceased to give pleasure.”
—Peregrine, Sir Worsthorne (b. 1923)
“A transition from an author’s books to his conversation, is too often like an entrance into a large city, after a distant prospect. Remotely, we see nothing but spires of temples, and turrets of palaces, and imagine it the residence of splendor, grandeur, and magnificence; but, when we have passed the gates, we find it perplexed with narrow passages, disgraced with despicable cottages, embarrassed with obstructions, and clouded with smoke.”
—Samuel Johnson (1709–1784)
