An excerpt from

As You Like It - Act II, Scene i

by William Shakespeare

And this our life, exempt from public haunt,
Finds tongues in trees, books in the running brooks,
Sermons in stones, and good in everything.

Explanation: These words, spoken by Duke Senior, highlight the pastoral nature of the Forest of Ardenne. This forest is his refuge from the perils of court life. The brook (read creek) contains "books" to the Duke, meaning that he sees this brook as a source of knowledge, and respects it for that. In short, everything in nature speaks to the Duke, teaching him that the natural world, where there is "good in everything" is an escape from the corrupt world of man.
