The exchange
You don't even know how bad your good can be, or how good,
bad can be. Nature stinks and makes use of the stink; Most of all, nature
confuses, and leaves you wiser. Nature is no friend, she offers no consolation
for naiveté, no reprieve from critical error, not even a symmetry -- in type or
degree -- in the exchange of "love" for "love." You must love wisdom to love life.
