Famous quotes containing the words open and/or class:
“Oh! joyous hearts! enfired with holy flame!
Is speech thus tasseled with praise?
Will not your inward fire of joy contain:
That it in open flames doth blaze?
For in Christ’s coach saints sweetly sing,
As they to glory ride therein.”
—Edward Taylor (1645–1729)
“He has more to impart than to receive from his generation. He is another such a strong and finished workman in his craft as Samuel Johnson was, and, like him, makes the literary class respectable.”
—Henry David Thoreau (1817–1862)
