I think that the cultivation of the humane letters has the most distinct bearing on the cultivation and appreciation of science. Science is nothing without imagination; and imagination is most readily kept fresh by literature. What little good there is a mere descriptive person, and in the small facts which with painful toil he accumulates. But let these facts be welded together by thought, their bearing traced by imagination, experiments devised by the mind projecting itself in advance of them, and the plodder is likely to become the great discoverer.
