"What is Duty?" he proceeded, "Whence the conviction, the mysterious fact, that whatever my inclination may be, I _ought_ to do some act--ought to do it though the cup of pleasure be dashed from the lifting hand, though a loved face most pale, though the stars in their high courses reel, and the gulfs of perdition smoke,--why is it that the grave, unalterable 'Ought' must still demand reverence?" His voice rose. "Immanuel Kant!" The familiar name caught my ear, and I attended. "To him Heaven gave it to solve the problem. Think what Reason is! Be men for once and attend to one deep matter! Think what Reason is!--the divinest part of us, and common with the Divine, as with every Intelligence; speaking not of the voice of the individual, but one sound everywhere to all. It is more truth than metaphor to name it the VOICE OF GOD." In my dream, the Professor repeated, as if with mystic significance, the cry: "Conscience is Reason!" and as these words vaguely reached me, his figure dissolved into a rolling cloud, which grew at once into a shape of giant form, and addressed me in echoing tones: "The unalterable Ought! the unalterable Ought!" reverberating from the depths and heights. I awoke at the sound, and collecting my energies--for I had been half-asleep,--stretched out my hand to my note-book, looked up the lecture, and with the words swaying before me, read sleepily:-- "Leave us Reason in any existence;--strip us of sight, sound, touch, and all the external constitution of nature, clothe us with whatever feelings and powers, place us in whatever scenes may come--but gift us with this universal faculty, our power of knowing truth. Otherwise, with rudder lost, we are dreamers on a drifting wreck, and where were the Divine One, and this harmonious architecture of the universe, and all things trustworthy, proportioned, eternal, exalting?" "Leave us Reason, and, children of God, we may from any point start out to see Our Father, His voice indicating from within the paths to Him which somewhere surely lie near to everywhere. Leave us Reason, and, brothers of men, we recognize that each Intelligence is of value equal to ourselves, and more precious than aught else can be, and we perceive the due relations of an orderly world." "The voice within in simple dignity commands"-- But the lines swam before me: I could not hold my head up: the Moorish room expanded to the height and magnificence of a Hall of Magic, the dream of starry space returned and the pure lights circled in it singing to me in chorus. Space itself seemed to become the veiled countenance of a Mysterious Power, which "half-revealed and half-concealed" itself on every hand, and out of the midst of a dark-blue sky, appeared the form and face of Alexandra, like a Princess-Madonna, smiling, O so earnestly and kindly.
