In short, if youth is not quite right in its opinions, there is a strong probability that age is not much more so. Undying hope is co-ruler of the human bosom with infallible credulity. A man finds he has been wrong at every preceding stage of his career, only to deduce the astonishing conclusion that he is at last entirely right. Mankind, after centuries of failure, are still upon the eve of a thoroughly constitutional millennium. Since we have explored the maze so long without result, it follows, for poor human reason, that we cannot have to explore much longer; close by must be the centre, with a champagne luncheon and a piece of ornamental water. How if there were no centre at all, but just one alley after another, and the whole world a labyrinth without end or issue? I overheard the other day a scrap of conversation, which I take the liberty to reproduce. "What I advance is true," said one. "But not the whole truth," answered the other. "Sir," returned the first (and it seemed to me there was a smack of Dr. Johnson in the speech), "Sir, there is no such thing as the whole truth!" Indeed, there is nothing so evident in life as that there are two sides to a question. History is one long illustration. The forces of nature are engaged, day by day, in cudgelling it into our backward intelligences. We never pause for a moment's consideration, but we admit it as an axiom. An enthusiast sways humanity exactly by disregarding this great truth, and dinning it into our ears that this or that question has only one possible solution; and your enthusiast is a fine florid fellow, dominates things for a while and shakes the world out of a doze; but when once he is gone, an army of quiet and uninfluential people set to work to remind us of the other side and demolish the generous imposture. While Calvin is putting everybody exactly right in his "Institutes," and hot-headed Knox is thundering in the pulpit, Montaigne is already looking at the other side in his library in Perigord, and predicting that they will find as much to quarrel about in the Bible as they had found already in the Church. Age may have one side, but assuredly Youth has the other. There is nothing more certain than that both are right, except perhaps that both are wrong. Let them agree to differ; for who knows but what agreeing to differ may not be a form of agreement rather than a form of difference? 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.
