The miseries and wickedness of humanity do not come from good, but good comes out of wickedness and miseries. If it were not for wickedness and miseries and wrong we would never have appreciated what good and right mean. It is the idea of these two opposite poles which makes us able to distinguish between the two qualities. If we had recognized only one, we would have called it goodness or wickedness, and it would have remained just one. Calling it by two different names helps us to distinguish between them.
