In science, reason is the guide; in poetry, taste. The object of the one is truth, which is uniform and indivisible; the object of the other is beauty, which is multiform and varied.
When God lets loose a great thinker on this planet, then all things are at risk. There is not a piece of science but its flank may be turned to-morrow; nor any literary reputation or the so-called eternal names of fame that many not be refused and condemned.
