A certain characteristic of Shelley, one which readers who know him only from anthologies will at once cite as his chief characteristic, seems to be strongly at variance with this unexampled personal intensity. I refer to the well-known fact that the most famous of his lyric poems are inspired by subjects outside of the emotional life, nay, outside of the world of man altogether; they treat of the cloud and the gale, of the life of the elements, of the marvellous freedom and stormy strength of wind and water. They are meteorological and cosmical poems. Yet there is no real contradiction in the most intimately emotional of lyric poets being, to all appearance, the most occupied with externals. We find the reason for it given by Shelley himself in a short essay _On Love_. He describes the essence of love as an irresistible craving for sympathy: "If we reason, we would be understood; if we imagine, we would that the airy children of our brain were born anew within another's; if we feel, we would that another's nerves should vibrate to our own, that lips of motionless ice should not reply to lips quivering and burning with the heart's best blood. This is Love ... The meeting with an understanding capable of clearly estimating our own; an imagination which should enter into and seize upon the subtle and delicate peculiarities which we have delighted to cherish and unfold in secret ... this is the invisible and unattainable point to which Love tends.... Hence in solitude, or in that deserted state when we are surrounded by human beings, and yet they sympathise not with us, we love the flowers, the grass, the waters, and the sky.... There is eloquence in the tongueless wind, and a melody in the flowing brooks which bring tears of mysterious tenderness to the eyes, like the voice of one beloved singing to you alone." In a note on _The Witch of Atlas_, Mrs. Shelley, too, writes that it was the certainty of neither being able to arouse the sympathy nor win the approbation of his countrymen, in combination with a shrinking from opening the wounds of his own heart by portraying human passion, which led her husband to seek forgetfulness in the airiest flights of fancy.
