'Who am I; what is this ME? A Voice, a Motion, an Appearance;--some embodied, visualised Idea in the Eternal Mind? _Cogito, ergo sum._ Alas, poor Cogitator, this takes us but a little way. Sure enough, I am; and lately was not: but Whence? How? Whereto? The answer lies around, written in all colours and motions, uttered in all tones of jubilee and wail, in thousand-figured, thousand-voiced, harmonious Nature: but where is the cunning eye and ear to whom that God-written Apocalypse will yield articulate meaning? We sit as in a boundless Phantasmagoria and Dream-grotto; boundless, for the faintest star, the remotest century, lies not even nearer the verge thereof: sounds and many-coloured visions flit round our sense; but Him, the Unslumbering, whose work both Dream and Dreamer are, we see not; except in rare half-waking moments, suspect not. Creation, says one, lies before us, like a glorious Rainbow; but the Sun that made it lies behind us, hidden from us. Then, in that strange Dream, how we clutch at shadows as if they were substances; and sleep deepest while fancying ourselves most awake! Which of your Philosophical Systems is other than a dream-theorem; a net quotient, confidently given out, where divisor and dividend are both unknown? What are all your national Wars, with their Moscow Retreats, and sanguinary hate-filled Revolutions, but the Somnambulism of uneasy Sleepers? This Dreaming, this Somnambulism is what we on Earth call Life; wherein the most indeed undoubtingly wander, as if they knew right hand from left; yet they only are wise who know that they know nothing.
