And this is our life, exempt from public haunt, finds tongues in trees, books in the running brooks, sermons in the stones and good in everything, I would not change it. What does this mean?
This quote is from Act II, Scene 1 of As You Like It, and it is spoken by the Duke. He is saying that in their life of exile, away from any civilized places, they can learn the language of the trees, read brooks like they were books, and hear sermons from the stones. In this life, they can understand nature and see the good in everything. The line "I would not change it" is actually a different speaker agreeing with the Duke, saying he would not give up the exile's life.
