Note 826 — Chapter I · : THE HISTORICAL SCHOOL AND THE CONFLICT OF METHODS

Knies, loc. cit., pp. 24-25. Ashley gives an unmistakable expression to the same opinion in his History. “Political economy is not a body of absolutely true doctrines, revealed to the world at the end of the last and the beginning of the present century, but a number of more or less valuable theories and generalisations.… Modern economic theories, therefore, are not universally true; they are true neither for the past, when the conditions they postulate did not exist, nor for the future, when, unless society becomes stationary, the conditions will have changed.” (Preface.)
