Ralph Waldo Emerson

Limits

Who knows this or that?
Hark in the wall to the rat:
Since the world was, he has gnawed;
Of his wisdom, of his fraud
What dost thou know?
In the wretched little beast
Is life and heart,
Child and parent,
Not without relation
To fruitful field and sun and moon.
What art thou? His wicked eye
Is cruel to thy cruelty.
