Poor human nature, what horrible crimes have been committed in thy name! Every fool, from king to policeman, from the flathead parson to the visionless dabbler in science, presume to speak authoritatively of human nature. The greater the mental charlatan, the more definite his insistence on the wickedness and weakness of human nature. Yet how can one speak of it today, with every soul in prison and every heart fettered, wounded, and maimed?
