I. There is a marked likeness between the virtues of man and the enlightenment of the globe he inhabits--the same diminishing gradation in vigor up to the limits of their domains, the same essential separation from their contraries--the same twilight at the meeting of the two: a something wider belt than the line where the world rolls into night, that strange twilight of the virtues; that dusky debateable land, wherein zeal becomes impatience, and temperance becomes severity, and justice becomes cruelty, and faith superstition, and each and all vanish into gloom. Nevertheless, with the greater number of them, though their dimness increases gradually, we may mark the moment of their sunset; and, happily, may turn the shadow back by the way by which it had gone down: but for one, the line of the horizon is irregular and undefined; and this, too, the very equator and girdle of them all--Truth; that only one of which there are no degrees, but breaks and rents continually; that pillar of the earth, yet a cloudy pillar; that golden and narrow line, which the very powers and virtues that lean upon it bend, which policy and prudence conceal, which kindness and courtesy modify, which courage overshadows with his shield, imagination covers with her wings, and charity dims with her tears. How difficult must the maintenance of that authority be, which, while it has to restrain the hostility of all the worst principles of man, has also to restrain the disorders of his best--which is continually assaulted by the one, and betrayed by the other, and which regards with the same severity the lightest and the boldest violations of its law! There are some faults slight in the sight of love, some errors slight in the estimate of wisdom; but truth forgives no insult, and endures no stain.
