Its work is at once critical and constructive. On the critical side we have a profound and suggestive, though not always a just, analysis of the principles and methods of the older economists, while its constructive efforts gave new scope to the science, extended the range of its observations, and added to the complexity of its problems.
Generally speaking, it is not a difficult task to give an exposition of the critical ideas of the school, as we find them set forth in several books and articles, but it is by no means easy to delineate the conceptions underlying the positive work. Though implicit in all their writings, these conceptions are nowhere explicitly stated; whenever they have tried to define them it has always been, as their disciples willingly admit, in a vague and contradictory fashion.[804] To add further to the difficulty, each author defines them after his own fashion, but claims that his definition represents the ideas of the whole school.
In order to avoid useless repetitions and discussions without number we shall begin with a rapid survey of the outward development of the school, following with a résumé of its critical work, attempting, finally, to seize hold of its conception of the nature and object of political economy. From our point of view the last-named object is by far the most interesting.
I: THE ORIGIN AND DEVELOPMENT OF THE HISTORICAL SCHOOL
The honour of founding the school undoubtedly belongs to Wilhelm Roscher, a Göttingen professor, who published a book entitled Grundriss zu Vorlesungen über die Staatswirtschaft nach geschichtlicher Methode in 1843. In the preface to that small volume he mentions some of the leading ideas which inspired him to undertake the work, which reached fruition in the celebrated System der Volkswirtschaft (1st ed., 1854). He makes no pretence to anything beyond a study of economic history. “Our aim,” says he, “is simply to describe what people have wished for and felt in matters economic, to describe the aims they have followed and the successes they achieved—as well as to give the reasons why such aims were chosen and such triumphs won. Such research can only be accomplished if we keep in close touch with the other sciences of national life, with legal and political history, as well as with the history of civilisation.”[805] Almost in the same breath he justifies an attack upon the Ricardian school. He recognises that he is far from thinking that his is the only or even the quickest way of attaining the truth, but thinks that it will lead into pleasant and fruitful quests, which once undertaken will never be abandoned.
What Roscher proposed to do was to try to complete the current theory by adding a study of contemporary facts and opinions, and, as a matter of fact, in the series of volumes which constitute the System, every instalment of which was received with growing appreciation by the German world of letters, Roscher was merely content to punctuate his exposition of the Classical doctrines with many an erudite excursus in the domain of economic facts and ideas.[806]
Roscher referred to his experiment as an attempt to apply the historical method which Savigny had been instrumental in introducing with such fruitful results into the study of jurisprudence.[807] But, as Karl Menger[808] has well pointed out, the similarity is only superficial. Savigny employed history in the hope of obtaining some light upon the organic nature and the spontaneous origin of existing institutions. His avowed object was to prove their legitimacy despite the radical pretensions of the Rationalist reformers of the eighteenth century. Roscher had no such aim in view. He was himself a Liberal, and fully shared in their reforming zeal. History with him served merely to illustrate theory, to supply rules for the guidance of the statesman or to foster the growth of what he called the political sense.
Schmoller thinks that Roscher’s work might justly be regarded as an attempt to connect the teaching of political economy with the “Cameralist” tradition of seventeenth- and eighteenth-century Germany.[809] These Cameralists were engaged in teaching the principles of administration and finance to students who were to spend their lives in administrative work of one kind or another, and they naturally took good care to keep as near actual facts as possible. Even in England and France political economy soon got involved in certain practical problems concerning taxation and commercial legislation. But in a country like Germany, which was industrially much more backward than either England or France, these problems wore a very different aspect, and some correction of the Classical doctrines was absolutely necessary if they were to bear any relation to the realities of economic life. Roscher’s innovation was the outcome of a pedagogic rather than of a purely scientific demand, and he was instrumental in reviving a university tradition rather than in creating a new scientific movement.
In 1848 another German professor, Bruno Hildebrand, put forward a much more ambitious programme, and his Die Nationalökonomie der Gegenwart und Zukunft shows a much more fundamental opposition to the Classical school. History, he thought, would not merely vitalise and perfect the science, but might even help to recreate it altogether. Hildebrand points to the success of the method when applied to the science of language. Henceforth economics was to become the science of national development.[810]
In the prospectus of the Jahrbücher für Nationalökonomie und Statistik, founded by him in 1863, Hildebrand goes a step farther. He challenges the teaching of the Classical economists, especially on the question of national economic laws, and he even blames Roscher because he had ventured to recognise their existence.[811] He did not seem to realise that a denial of that kind involved the undoing of all economic science and the complete overthrow of those “laws of development” which he believed were henceforth to be the basis of the science.
