One of the most suggestive facts of the post-war situation is that European civilization almost breaks down before one of the simplest of its mechanical problems: that of 'moving some stones from where they are not needed to the places where they are needed,' in other words before the problem of mining and distributing coal. Millions of children have died in agony in France during this last year or two because there was no coal to transport the food, to warm the buildings. Coal is the first need of our massed populations. Its absence means collapse of everything--of transport, of the getting of food to the towns, of furnishing the machinery and fertilisers by which food can be produced in sufficient quantity. It is warmth, it is clothing, it is light, it is the daily newspaper, it is water, it is communication. All our elaboration of knowledge and science fails in the presence of this problem of 'taking some stones from one heap and putting them on another.' The coal famine is a microcosm of the world's present failure. But if all those things--and spiritual things also are involved because the absence of material well-being means widespread moral evils--depend upon coal, the getting of the coal itself is dependent upon them. We have touched upon the importance of the one element of sheer goodwill on the part of the miners as a factor in the production of coal; upon the hopelessness of making good its absence by physical coercion. But we have also seen that just as the attempted use of coercion in the international field, though ineffective to exact necessary service or exchange, can and does produce paralysis of the indispensable processes, so the 'power' which the position of the miner gives him is a power of paralysis only. A later chapter shows that the instinct of industrial groups to solve their difficulties by simple coercion, the sheer assertion of power, is very closely related to the psychology of nationalism, so disruptive in the international field. Bolshevism, in the sense of belief in the effectiveness of coercion, represents the transfer of jingoism to the industrial struggle. It involves the same fallacies. A mining strike can bring the industrial machine to a full stop; to set that machine to work for the feeding of the population--which involves the co-ordination of a vast number of industries, the purchase of food and raw material from foreigners, who will only surrender it in return for promises to pay which they believe will be fulfilled--means not only technical knowledge, it means also the presence of a certain predisposition to co-operation. This Balkanised Europe which cannot feed itself has all the technical knowledge that it ever had. But its natural units are dominated by a certain temper which make impossible the co-operations by which alone the knowledge can be applied to the available natural resources.
