Clarence Darrow's Quote About "Justice" and "Charity, Understanding, & Mercy"

Clarence Darrow said:

We have heard talk of “justice.” Is there anybody who knows what justice is? No one on earth can measure out justice. Can you look at any man and say what he deserves -- whether he deserves hanging by the neck until dead or life in prison or thirty days in prison or a medal? The human mind is blind to all who seek to look in at it and to most of us that look out from it. Justice is something that man knows little about. He may know something about charity and understanding and mercy, and he should cling to those as far as he can.
