From this it does not follow that nature's forces do not make for altruism. As the family, the tribe or clan, the race, and the nation are successively evolved, the scope of self-interest widens and the means necessary to attain its ends become less individualistic and more humanitarian. As Fagin impresses on Noah Claypole, even in a band of thieves, the number one of Noah must also include the number one of the other members of the gang. In a modern community, whether Christian or heathen, the successful business or professional man must necessarily practice, to a greater or less degree, the same virtues inculcated by Jesus; otherwise he makes himself an outcast--an Ishmaelite--against whom every man's hand is turned. "Honesty is the best policy" of the utilitarian leads to the same results as the Gospel maxim "to deal justly with all men." Also the growth of a world-wide commerce, with the accompanying spread of international law, develops constantly a spirit of international morality. A nation today, planning a war, must look beyond the question of how its course will affect the self-interest of other nations. If it has wisdom in its councils, it must also reckon with this spirit of international morality. If its cause be too palpably unjust, or the means it adopts to secure victory be too barbarous, it may shock this international morality, and bring upon itself unexpected enemies, who may balk its best laid plans. The possibility of such contingencies arising will have far more weight than any argument based on the teaching of Jesus. THE NECESSITY OF COMPROMISE In Physics a body acted on by two divergent forces takes a course which is the resultant of (a compromise between) the two different forces. So, if Christianity is to survive as an efficient force in man's evolution, compromises must be made between the ideals of Jesus and the natural forces expressed in the terms of the struggle for existence and the survival of the fittest. It is possible that the day may come, when all nations of our planet may be converted, to put into practical operation in international affairs the ideals of Jesus. But the experience of the world during 1914 shows that little, if any, progress has been made in that direction since the Crucifixion. Suppose the Christian nations of Europe and America should announce today the doctrine of non-resistance, dismantle their fleets and dismiss their armies, how long would it be before the Moslems, or the "yellow hordes" of Asia, would enslave them and exterminate all Christian religion and civilization? Fortunately, such a result is unthinkable, and the Christian nations will, until some unknown time in the future, continue their compromise with Jesus' ideals. The unspeakable Turk will continue to understand that, if he massacres some Christian villages, the other cheek will not be turned to him, but, on the contrary, a righteous retribution of bayonet and shell will be meted out to him.
