We have a collection of 2 Wisdom quotes from William Butler Yeats
"Books are but waste paper unless we spend in action the wisdom we get from thought - asleep. When we are weary of the living, we may repair to the dead, who have nothing of peevishness, pride, or design in their conversation." (ID 3217)
"If suffering brings wisdom, I would wish to be less wise." (ID 3230)
