If it were not that every child of earth must learn wisdom for himself in the school of pain and labour, and if experience were orally communicable, as old people are prone to fancy, and if youth were less conceited and selfish, comparatively few foolish things would be done, and this life would lose, in a large measure, its efficacy as a place of discipline.
Thus, in the rough, the coarse old comedy is true; a great gulf separates age and youth. The youngsters will, to the end of time, prefer new lamps to old: they will trust their own senses, not yours. Buzz in the ears of your brood that flame burns and cobwebs catch. Their senses tell them that candlelight and warmth are pleasant, and liberty to fly high or low as one pleases; and, therefore, your love may as well be silent on those subjects. Otherwise you become, in their eyes, but a venerable muff and a bore. Nature has ordained that their nerves shall quiver, as yours have done, and their hearts thumb with fear; and when their turn comes they will scorch their wings, as you have, and make acquaintance with the spider.
Joseph Sheridan Le Fanu, The Rose and the Key
