I suppose it is written that any one who sets up for a bit of a philosopher, must contradict himself to his very face. For here have I fairly talked myself into thinking that we have the whole thing before us at last; that there is no answer to the mystery, except that there are as many as you please; that there is no centre to the maze because, like the famous sphere, its centre is everywhere; and that agreeing to differ with every ceremony of politeness, is the only "one undisturbed song of pure concent” to which we are ever likely to lend our musical voices.
