“True; but look, now, what my doubt is. I am one who thinks well of man. I love man. I have confidence in man. But what was told me not a half-hour since? I was told that I would find it written—‘Believe not his many words—an enemy speaketh sweetly with his lips’—and also I was told that I would find a good deal more to the same effect, and all in this book. I could not think it; and, coming here to look for myself, what do I read? Not only just what was quoted, but also, as was engaged, more to the same purpose, such as this: ‘With much communication he will tempt thee; he will smile upon thee, and speak thee fair, and say What wantest thou? If thou be for his profit he will use thee; he will make thee bear, and will not be sorry for it. Observe and take good heed. When thou hearest these things, awake in thy sleep.’” “Who’s that describing the confidence-man?” here came from the berth again.
