Thus, Sir Arthur Conan Doyle, an intelligent man in other matters, says that there is only a "theological" opposition to divorce, and that it is entirely founded on "certain texts" in the Bible about marriages. This is exactly as if he said that a belief in the brotherhood of men was only founded on certain texts in the Bible, about all men being the children of Adam and Eve. Millions of peasants and plain people all over the world assume marriage to be static, without having ever clapped eyes on any text. Numbers of more modern people, especially after the recent experiments in America, think divorce is a social disease, without having ever bothered about any text. It may be maintained that even in these, or in any one, the idea of marriage is ultimately mystical; and the same may be maintained about the idea of brotherhood. It is obvious that a husband and wife are not visibly one flesh, in the sense of being one quadruped. It is equally obvious that Paderewski and Jack Johnson are not twins, and probably have not played together at their mother's knee. There is indeed a very important admission, or addition, to be realised here. What is true is this: that if the nonsense of Nietzsche or some such sophist submerged current culture, so that it was the fashion to deny the duties of fraternity; then indeed it might be found that the group which still affirmed fraternity was the original group in whose sacred books was the text about Adam and Eve. Suppose some Prussian professor has opportunely discovered that Germans and lesser men are respectively descended from two such very different monkeys that they are in no sense brothers, but barely cousins (German) any number of times removed. And suppose he proceeds to remove them even further with a hatchet, suppose he bases on this a repetition of the conduct of Cain, saying not so much "Am I my brother's keeper?" as "Is he really my brother?" And suppose this higher philosophy of the hatchet becomes prevalent in colleges and cultivated circles, as even more foolish philosophies have done. Then I agree it probably will be the Christian, the man who preserves the text about Cain, who will continue to assert that he is still the professor's brother; that he is still the professor's keeper. He may possibly add that, in his opinion, the professor seems to require a keeper.
And that is doubtless the situation in the controversies about divorce and marriage to-day. It is the Christian church which continues to hold strongly, when the world for some reason has weakened on it, what many others hold at other times. But even then it is barely picking up the shreds and scraps of the subject to talk about a reliance on texts. The vital point in the comparison is this: that human brotherhood means a whole view of life, held in the light of life, and defended, rightly or wrongly, by constant appeals to every aspect of life. The religion that holds it most strongly will hold it when nobody else holds it; that is quite true, and that some of us may be so perverse as to think a point in favour of the religion. But anybody who holds it at all will hold it as a philosophy, not hung on one text but on a hundred truths. Fraternity may be a sentimental metaphor; I may be suffering a delusion when I hail a Montenegrin peasant as my long lost brother. As a fact, I have my own suspicions about which of us it is that has got lost. But my delusion is not a deduction from one text, or from twenty; it is the expression of a relation that to me at least seems a reality. And what I should say about the idea of a brother, I should say about the idea of a wife.
