Love without marriage can sometimes be very awkward for all concerned; but marriage without love simply removes that institution from the territory of the humanly admissible, to my mind. Love is a state in which one lives who loves, and whoever loves has given himself away; love then, and not marriage, is belonging. Marriage is a public declaration of a man and a woman that they have formed a secret alliance, with the intention to belong to, and share with each other, a mystical estate; mystical exactly in the sense that the real experience cannot be communicated to others, nor explained even to oneself on rational grounds.
