Yet a certain jealousy _does_ exist, if not between you and me personally, at least between our classes. The men who have culture without wealth are jealous of the power and privileges of those who possess money without culture; and on the other hand, the men whose time has been too entirely absorbed by commercial pursuits to leave them any margin sufficient to do justice to their intellectual powers, are often painfully sensitive to the contempt of the cultivated, and strongly disposed, from jealousy, to undervalue culture itself. Both are wrong so far as they indulge any unworthy and unreasonable feeling of this kind. The existence of the two classes is necessary to an advanced civilization. The science of accumulating and administrating material wealth, of which you yourself are a great practical master, is the foundation of the material prosperity of nations, and it is only when this prosperity is fully assured to great numbers that the arts and sciences can develop themselves in perfect liberty and with the tranquil assurance of their own permanence. The advancement of material well-being in modern states tends so directly to the advancement of intellectual pursuits, even when the makers of fortunes are themselves indifferent to this result, that it ought always to be a matter of congratulation for the intellectual class itself, which needs the support of a great public with leisure to read and think. It is easy to show how those arts and sciences which our class delights to cultivate are built upon those developments of industry which have been brought about by the energy of yours. Suppose the case of a scientific chemist: the materials for his experiments are provided ready to his hand by the industrial class; the record of them is preserved on paper manufactured by the same industrial class; and the public which encourages him by its attention is usually found in great cities which are maintained by the labors of the same useful servants of humanity. It is possible, no doubt, in these modern times, that some purely pastoral or agricultural community might produce a great chemist, because a man of inborn scientific genius who came into the world in an agricultural country might in these days get his books and materials from industrial centres at a distance, but his work would still be based on the industrial life of others. No pastoral or agricultural community which was really isolated from industrial communities ever produced a chemist. And now consider how enormously important this one science of chemistry has proved itself even to our intellectual life! Several other sciences have been either greatly strengthened or else altogether renewed by it, and the wonderful photographic processes have been for nature and the fine arts what printing was for literature, placing reliable and authentic materials for study within the reach of every one. Literature itself has profited by the industrial progress of the present age, in the increased
