And still drink knowledge, wine-drenched every turn,—
Equally favored by their opposites.
Little and Bad exist, are natural:
Then let me know them, and be twice as great
As he who only knows one phase of life!
So doubly shall I prove 'best friend of man,'
If I report the whole truth—Vice, perceived
While he shut eyes to all but Virtue there.
Man 's made of both: and both must be of use
To somebody: if not to him, to me.
