"It may be hard for an egg to turn into a bird; it would be a jolly sight harder for it to learn to fly while remaining an egg. We are like eggs at present. And you cannot go on indefinitely being just an ordinary, decent egg. We must be hatched or go bad." --C. S. Lewis.
" 'Well, do you do that consciously?' Daily Alice asked, only partly of Cloud.
'Do what?' Cloud asked. 'Grow up? No. Well. In a sense. You see it's inevitable, or refuse to. You greet it or don't--take it in trade, maybe, for all you're going to lose anyway. Or you can refuse, and have what you've got to lose snatched from you, and never take payment--never see a trade is possible.' " --John Crowley.
"What will make him an old man is a frightened clinging to the values of the first half of his life. We have all seen these juvenile dotards whose boast is that they are just as young as their sons or their grandsons; they do not realize what a pitiful boast that is. They prate about their sympathy with youth, but they mean only the superficialities and ephemera of youth. Many of the sad smashups in marriages that we see among middle-aged people have their origin in this attempt to dodge an inescapable fact. The values that are proper and all-absorbing during the first half of life will not sustain a man during the second half. If he has the courage and wisdom to advance courageously into the new realm of values and emotions he will age physically, of course, but his intellectual and spiritual growth will continue, and will give satisfaction to himself and to all those associated with him. And such courage and wisdom are by no means rare; they may show themselves among many people who have never thought along those lines at all but who have a knack for living life wisely; and they also are to be found among those who regard self-awareness as one of the primary duties of a good life. Paradoxically, such people are on better terms with youth than the shrivelled Peter Pans who dare not be their age." --Robertson Davies.
