“I should tell you all with pleasure,” said the General, “but you would not believe me.” “Why should I not?” he asked. “Because,” he answered testily, “you believe in nothing but what consists with your own prejudices and illusions. I remember when I was like you, but I have learned better.” “Try me,” said my father; “I am not such a dogmatist as you suppose. Besides which, I very well know that you generally require proof for what you believe, and am, therefore, very strongly predisposed to respect your conclusions.”
