The opinion of a man who had reached the highest point to which a civilian could aspire, cannot, when he estimates the honours of the Chancellor as inferior to those of the natural philosopher, be ascribed to misjudging enthusiasm or personal disappointment. Without, however, seeking, for the sake of antithetic contrast, to underrate the importance of political services, civil or military, or to exaggerate those of the man of science, few, we think, will be disposed to deny that, although the one may be temporarily more urgent and necessary to the well-being of an existing race, yet that the benefits of the other are more lasting and universal. If, then, the influence on mankind of the secluded inventor be more extensive and durable than that of the active politician--if there be any truth in the opinion of Bacon, that the greatest political changes are wrought by the peaceful under-current of science; why is it that those who occupy the highest place as permanent benefactors of mankind, are, during their lifetime, neglected and comparatively unknown;--that they obtain neither the tangible advantages of pecuniary emolument, nor the more suitable, but less lucrative, honours of grateful homage? It is the common cry to exclaim against the neglect of science in the present day. Alas! history does not show us that our predecessors were more just to their scientific contemporaries. The evil is to a great extent remediless, the complaint to some extent irrational, and unworthy the dignity of the cause. The labourer in the field of science works not for the present, but for succeeding generations; he plants oaks for posterity, and must not look for the gratitude of contemporaries. Men will remunerate less, and be less grateful for, prospective than for present good--for benefits secured to their posterity than to themselves; the realization of the advantages is so distant, that the amount of discount is coextensive with the debt: it is only as the applications of science become more immediate, that the cultivators of science can reasonably expect an adequate reward or appreciation.
