"How different," said Harrington, "are the experiences of mankind! You well described those internal oracles, if there are indeed such, as whispering their responses; if they utter them at all, it is to me in a whisper so low that I cannot distinctly catch them. Strange paradoxes! the soul speaks, and the soul listens, and the soul cannot tell what the soul says. That is, the soul speaks to itself, and says, 'What have I said?' I assure you that the ear of my soul (if I may so speak) has often ached with intense effort to listen to what the tongue of the soul mutters, and yet I cannot catch it. You tell me I have only to look down into the depths within. Well, I have. I assure you that I have endeavoured to do so, as far as I know, honestly; and, so far from seeing clear and bright those splendors which you speak of, I can only see as in the depths of a cavern occasional gleams of a tremulous flickering light, which distinctly shows me nothing, and which, I half suspect, comes from without into these recesses: or I feel as if gazing down an abyss, the bottom of which is filled with water; the light--and that, too, for aught I know, reflected from without--only throws a transient glimpse of my own image on the surface of the dark water; that image itself broken and renewed as the water boils up from its hidden fountain. Or, if I may recur to your own metaphor, instead of hearing in those deep caverns the clear oracles of which you boast, I can distinguish nothing but a scarcely audible murmur; I know not whether it be any thing more than the lingering echoes of what I heard in my childhood: or, rather, my soul speaks to me on all these momentous subjects much as one in sleep often does; the lips move, but no sound issues from them. I retire from these attempts, as those of old from the cave of Trophonius, pale, terrified, and dejected. In short," he continued, "I feel much as Descartes says he did when he had denuded himself of all his traditional opinions,--a condition so graphically described in the beginning of the second of his Meditations. There is this difference, however, and in his favor: that he imposed upon himself only a self-inflicted doubt, which he could terminate at any time. His opinions had been but temporarily laid aside. They were on the shelf, close at hand, ready to be taken down again when wanted. But enough of this. You will, I know, aid me, if you can. And, now I think of it, do so on one point, by justifying your assertion, made the other evening, as to Mr. Newman's dilemma of the 'impossibility of a book-revelation.'" "I said, I think, that Mr. Newman has satisfactorily proved to me that a book-revelation of moral and spiritual truth is impossible; that God reveals himself to us within, and not from without."
