and delicate union than that which binds men's affections, imagination, wit and humor with the subtle ramifications of historical language. Language must be left to grow in precision, completeness and unity, as minds grow in clearness, comprehensiveness and sympathy. And there is an analogous relation between the moral tendencies of men and the social conditions they have inherited. The nature of European men has its roots intertwined with the past, and can only be developed by allowing those roots to remain undisturbed while the process of development is going on, until that perfect ripeness of the seed which carries with it a life independent of the root.... It has not been sufficiently insisted on, that in the various branches of social science there is an advance from the general to the special, from the simple to the complex, analogous with that which is found in the series of the sciences, from mathematics to biology. To the laws of quantity comprised in mathematics and physics are superadded, in chemistry, laws of quality; to those again are added, in biology, laws of life; and lastly, the conditions of life in general branch out into its special conditions, or natural history, on the one hand, and into its abnormal conditions, or pathology, on the other. And in this series or ramification of the sciences, the more general science will not suffice to solve the problems of the more special. Chemistry embraces phenomena which are not explicable by physics; biology embraces phenomena which are not explicable by chemistry; and no biological generalization will enable us to predict the infinite specialties produced by the complexity of vital conditions. So social science, while it has departments which in their fundamental generality correspond to mathematics and physics, namely, those grand and simple generalizations which trace out the inevitable march of the human race as a whole, and, as a ramification of these, the laws of economical science, has also, in the departments of government and jurisprudence, which embrace the conditions of social life in all their complexity, what may be called its biology, carrying us on to innumerable special phenomena which outlie the sphere of science, and belong to natural history. And just as the most thorough acquaintance with physics, or chemistry, or general physiology, will not enable you at once to establish the balance of life in your private vivarium, so that your particular society of zoophytes, molluscs and echinoderms may feel themselves, as the Germans say, at ease in their skins; so the most complete equipment of theory will not enable a statesman or a political and social reformer to adjust his measures wisely, in the absence of a special acquaintance with the section of society for which he
