Famous quotes containing the words year and/or pack:
“We know of no scripture which records the pure benignity of the gods on a New England winter night. Their praises have never been sung, only their wrath deprecated. The best scripture, after all, records but a meagre faith. Its saints live reserved and austere. Let a brave, devout man spend the year in the woods of Maine or Labrador, and see if the Hebrew Scriptures speak adequately to his condition and experience.”
—Henry David Thoreau (18171862)
“Youre nothing but a pack of cards!”
—Lewis Carroll [Charles Lutwidge Dodgson] (18321898)
