"THE PROBLEM is not in marriage, but in sex; and would be felt under the freest concubinage. Nevertheless, the overwhelming mass of mankind has not believed in freedom in this matter, but rather in a more or less lasting tie. Tribes and civilizations differ about the occasions on which we may loosen the bond, but they all agree that there is a bond to be loosened, not a mere universal detachment. For the purposes of this book I am not concerned to discuss that mystical view of marriage in which I myself believe: the great European tradition which has made marriage a sacrament. It is enough to say here that heathen and Christian alike have regarded marriage as a tie; a thing not normally to be sundered. Briefly, this human belief in a sexual bond rests on a principle of which the modern mind has made a very inadequate study. It is, perhaps, most nearly paralleled by the principle of the second wind in walking.
"The principle is this: that in everything worth having, even in every pleasure, there is a point of pain or tedium that must be survived, so that the pleasure may revive and endure. The joy of battle comes after the first fear of death; the joy of reading Virgil comes after the bore of learning him; the glow of the sea-bather comes after the icy shock of the sea bath; and the success of the marriage comes after the failure of the honeymoon. All human vows, laws, and contracts are so many ways of surviving with success this breaking point, this instant of potential surrender.
"In everything on this earth that is worth doing, there is a stage when no one would do it, except for necessity or honor. It is then that the Institution upholds a man and helps him on to the firmer ground ahead. Whether this solid fact of human nature is sufficient to justify the sublime dedication of Christian marriage is quite an other matter, it is amply sufficient to justify the general human feeling of marriage as a fixed thing, dissolution of which is a fault or, at least, an ignominy. The essential element is not so much duration as security. Two people must be tied together in order to do themselves justice; for twenty minutes at a dance, or for twenty years in a marriage In both cases the point is, that if a man is bored in the first five minutes he must go on and force himself to be happy. Coercion is a kind of encouragement; and anarchy (or what some call liberty) is essentially oppressive, because it is essentially discouraging. If we all floated in the air like bubbles, free to drift anywhere at any instant, the practical result would be that no one would have the courage to begin a conversation. It would be so embarrassing to start a sentence in a friendly whisper, and then have to shout the last half of it because the other party was floating away into the free and formless ether. The two must hold each other to do justice to each other..."
