The tramp has committed a murder. It was a cowardly and cruel murder,
and the motive was robbery.
But I have proved that all motives and all powers; all knowledge
and capacity, all acts and all words, are caused by heredity and
environment.
I have proved that a man can only be good or bad as heredity and
environment cause him to be good or bad; and I have proved these things
because I have to claim that all punishments and rewards, all praise and
blame, are undeserved.
And now, let us try this miserable tramp--our brother.
