As soon go kindle fire with snow, as seek to quench the fire... - William Shakespeare

"We know what we are, but not what we may be."

"Love is a smoke made with the fume of sighs."

"Knowing I lov'd my books, he furnish'd me From mine own library with volumes that I prize above my dukedom."

"Of all knowledge, the wise and good seek mostly to know themselves."

"Tongues in trees, books in running brooks, sermons in stones, and good in everything."
