The justification of protection is to be found not in its con formity or its departure from an abstract theory, but in the condi tions which govern the development of actual states and the laws o; their development. It does not really belong to the domain of abstract economics, but to statecraft and practical organisation. The range of philosophical and other assumptions underlying the pure theory of economics is neither wide nor accurate enough to cover the varied motives and activities of an organic com munity, and men may at the same time accept and make use of the theory of economics so far as it goes, and yet be strong pro tectionists in action. In the article on ECONOMICS it has been shown how to use economic theory in investigation in opening up the relations between different series of economic facts and in suggesting approximations for the solution of practical problems. But the world we live in is a world of realities and of varying policies. We are dealing with nations, communities, human beings and concrete things, and it can never be assumed that the world does or ought to conform to the requirements of a purely theo retical system. The objections to protection in a hypothetical world where there is complete mobility of labour and capital, and time is an abstraction, are not relevant when we have to consider the great industries and the lines of commerce of the actual world, the tangled relations of the groups of human beings, their different histories and environment, and the divergent interests with which statesmen have to deal. If we keep in view the wide gulf between the world of pure theory and the conditions of actual life, we shall not hastily come to the conclusion that the states which have practised a protective policy have achieved success in spite of the measures they have adopted to secure it.
Great Britain and Ireland became one economic area. By that time the United kingdom, under the policy which was so widely condemned later on by economists, achieved economic supremacy. With apparently illimitable supplies of coal and other requisites of production, her industries growing by leaps and bounds from the use of new inventions, the whole organisation and structure of great industries rapidly changing, the old laws and methods of regulation became obsolete, and the tariffs worked out to suit the more primitive stages of industrial development were simply embarrassing or irrelevant in the new conditions. Attempts to adapt them failed and the old duties were swept away, not so much in obedience to a theory but because the necessary adapta tions could not be made. It might have been more statesmanlike and prudent to keep at least the framework of the old system, but with wealth as the supreme end in life and with the opportu nities which the new industrialism gave, this was the accepted course of contemporary statesmen. By 186o free importation was the established policy of the country and the methods by which English statesmen had built up the economic power of the country were remembered simply as the economic fallacies of a former generation.
