"I have heard from persons in pursuits different from yours — from the lawyer, from the congressman, from the editor, not to mention others, each, with a strange kind of melancholy vanity, claiming for his vocation the distinction of affording the surest inlets to the conviction that man is no better than he should be. All of which testimony, if reliable, would, by mutual corroboration, justify some disturbance in a good man's mind."
