The same principle operates still more strikingly in the remarkable contempt of men of genius for those pursuits which require talents distinct from their own, and a cast of mind thrown by nature into another mould. Hence we must not be surprised at the poetical antipathies of Selden and Locke, as well as Longuerue and Buffon. Newton called poetry "ingenious nonsense." On the other side, poets undervalue the pursuits of the antiquary, the naturalist, and the metaphysician, forming their estimate by their own favourite scale of imagination. As we can only understand in the degree we comprehend, and feel in the degree in which we sympathize, we may be sure that in both these cases the parties will be found altogether deficient in those qualities of genius which constitute the excellence of the other. To this cause, rather than to the one the friends of MICKLE ascribed to ADAM SMITH, namely, a personal dislike to the poet, may we place the severe mortification which the unfortunate translator of Camoens suffered from the person to whom he dedicated "The Lusiad." The Duke of Buccleugh was the pupil of the great political economist, and so little valued an epic poem, that his Grace had not even the curiosity to open the leaves of the presentation copy. A professor of polite literature condemned the study of botany, as adapted to mediocrity of talent, and only demanding patience; but LINNAEUS showed how a man of genius becomes a creator even in a science which seems to depend only on order and method. It will not be a question with some whether a man must be endowed with the energy and aptitude of genius, to excel in antiquarianism, in natural history, and similar pursuits. The prejudices raised against the claims of such to the honours of genius have probably arisen from the secluded nature of their pursuits, and the little knowledge which the men of wit and imagination possess of these persons, who live in a society of their own. On this subject a very curious circumstance has been revealed respecting PEIRESC, whose enthusiasm for science was long felt throughout Europe. His name was known in every country, and his death was lamented in forty languages; yet was this great literary character unknown to several men of genius in his own country; Rochefoucauld declared he had never heard of his name, and Malherbe wondered why his death created so universal a sensation.
