Famous quotes containing the word read:
“Vanity is so anchored in the heart of man that a soldier, a soldier’s servant, a cook, a porter brags and wishes to have his admirers. Even philosophers wish for them. Those who write against vanity want to have the glory of having written well; and those who read it desire the glory of having read it. I who write this have perhaps this desire, and perhaps those who will read it.”
—Blaise Pascal (1623–1662)
