It is a great luck to be born in an island. The girdle of sea is a safeguard which gives a sense of security to the whole psychology of a race, and for that reason there is a gulf of ignorance about the terrors of war which, happily, may never be bridged by the collective imagination of English and Scottish people. A continental nation, divided by a few hills, a river, or a line on the map, from another race with other instincts and ideals, is haunted throughout its history by a sense of peril. Even in times of profound peace, the thought is there, in the background, with a continual menace. It shapes the character of a people and enters into all their political and educational progress. To keep on friendly terms with a powerful next-door neighbour, or to build defensive works high enough to make hostility a safe game, is the lifework of its statesmen and its politicians. Great crises and agitations shake the nation convulsively when cowardice or treachery or laziness has allowed that boundary wall to crumble or has made a breach in it. The violence of the Dreyfus affair was not so much due to a Catholic detestation of the Jewish race, but in its root-instincts to a fear of the German people over the frontier making use of French corruption to sap the defensive works which had been raised against them. The necessity of conscription is obvious beyond argument to a continental people still cherishing old traditions of nationality, and the military training which is compulsory for all young men of average health, not only shapes the bodies of their lads, but also shapes their minds, so that their outlook upon life is largely different from that of an island people protected by the sea. They know that they have been born of women for one primary object--to fight when the time comes in, defence of the Fatherland, to make one more human brick in the great wall of blood and spirit dividing their country and race from some other country and race. At least that is the lesson taught them from first to last in the schools and in the national assemblies, and there are only a few minds which are able to see another way of life when the walls of division may be removed and when the fear of a next-door neighbour may be replaced by friendship and common interests.
