(3. Note to the chorus, 'Worlds on worlds are rolling ever,' &c.) 'The first stanza contrasts the immortality of the living and thinking beings which inhabit the planets and (to use a common and inadequate phrase) clothe themselves in matter, with the transcience of the noblest manifestations of the external world. The concluding verses indicate a progressive state of more or less exalted existence, according to the degree of perfection which every distinct intelligence may have attained. Let it not be supposed that I mean to dogmatise upon a subject concerning which all men are equally ignorant, or that I think the Gordian knot of the origin of evil can be disentangled by that or any similar assertions.... That there is a true solution of the riddle, and that in our present state that solution is unattainable by us, are propositions which may be regarded as equally certain: meanwhile, as it is the province of the poet to attach himself to those ideas which exalt and ennoble humanity, let him be permitted to have conjectured the condition of that futurity towards which we are all impelled by an inextinguishable thirst for immortality. Until better arguments can be produced than sophisms which disgrace the cause, this desire itself must remain the strongest and the only presumption that eternity is the inheritance of every thinking being.' The reader will perceive that in these three passages the dominant ideas, very briefly stated, are as follows:--(1) Mind is the aggregate of all individual minds; (2) man has no reason for expecting that his mind or soul will be immortal; (3) no reason, except such as inheres in the very desire which he feels for immortality. These opinions, deliberately expressed by Shelley at different dates as a theorist in prose, should be taken into account if we endeavour to estimate what he means when, as a poet, he speaks, whether in _Hellas_ or in _Adonais_, of an individual, his mind and his immortality. When Shelley calls upon us to regard Keats (Adonais) as mortal in body but immortal in soul or mind, his real intent is probably limited to this: that Keats has been liberated, by the death of the body, from the dominion and delusions of the senses; and that he, while in the flesh, developed certain fruits of mind which survive his body, and will continue to survive it indefinitely, and will form a permanent inheritance of thought and of beauty to succeeding generations. Keats himself, in one of his most famous lines, expressed a like conception, 'A thing of beauty is a joy for ever.'
