As long as man was only the slave of physical necessity, while he had found no issue to escape from the narrow circle of his appetites, and while he as yet felt none of that superior liberty which connects him with the _angels_, nature, so far as she is _incomprehensible_, could not fail to impress him with the insufficiency of his imagination, and again, as far as she is a destructive force, to recall his physical powerlessness. He is forced then to pass timidly towards one, and to turn away with affright from the other. But scarcely has free contemplation assured him against the blind oppression of the forces of nature—scarcely has he recognized amidst the tide of phenomena something permanent in his own being—than at once the coarse agglomeration of nature that surrounds him begins to speak in another language to his heart, and the relative grandeur which is without becomes for him a mirror in which he contemplates the absolute greatness which is within himself. He approaches without fear, and with a thrill of pleasure, those pictures which terrified his imagination, and intentionally makes an appeal to the whole strength of that faculty by which we represent the infinite perceived by the senses, in order if she fails in this attempt, to feel all the more vividly how much these ideas are superior to all that the highest sensuous faculty can give. The sight of a distant infinity—of heights beyond vision, this vast ocean which is at his feet, that other ocean still more vast which stretches above his head, transport and ravish his mind beyond the narrow circle of the real, beyond this narrow and oppressive prison of physical life. The simple majesty of nature offers him a less circumscribed measure for estimating its grandeur, and, surrounded by the grand outlines which it presents to him, he can no longer bear anything mean in his way of thinking. Who can tell how many luminous ideas, how many heroic resolutions, which would never have been conceived in the dark study of the imprisoned man of science, nor in the saloons where the people of society elbow each other, have been inspired on a sudden during a walk, only by the contact and the generous struggle of the soul with the great spirit of nature? Who knows if it is not owing to a less frequent intercourse with this sublime spirit that we must partially attribute the narrowness of mind so common to the dwellers in towns, always bent under the minutiæ which dwarf and wither their soul, whilst the soul of the nomad remains open and free as the firmament beneath which he pitches his tent?
