"[A man] expects an angel for a wife; [yet] he knows that she is like himself—erring, thoughtless and untrue; but like himself also, filled with a struggling radiancy of better things, and adorned with ineffective qualities. You may safely go to school with hope; but ere you marry, should have learned the mingled lesson of the world:[…] that hope and love address themselves to a perfection never realized, and yet, firmly held, become the salt and staff of life; that you yourself are compacted of infirmities, perfect, you might say, in imperfection, and yet you have a something in you lovable and worth preserving; and that, while the mass of mankind lies under this scurvy condemnation, you will scarce find one but, by some generous reading, will become to you a lesson, a model and a noble spouse through life. So thinking, you will constantly support your own unworthiness and easily forgive the failings of your friend. Nay, you will be wisely glad that you retain the sense of blemishes; for the faults of married people continually spur up each of them, hour by hour, to do better and to meet and love upon a higher ground."
