Thy light alone, like mist on mountains driven, Or music by the night wind sent Through strings of some still instrument, Or moonlight on a midnight stream, Gives peace and truth to life's unquiet dream.
In presence of such speculations, the ordinary mass of mankind will be content with declaring that the doctrine, if it can be called a doctrine, is totally unintelligible. The ideal world is upon this vein so hopelessly dissevered from the real, that it can give us no consolation. If life is a dream, the dream is the basis of all we know, and it is small comfort to proclaim its unreality. A truth existing all by itself in a transcendental vacuum entirely unrelated to all that we call fact, is a truth in which we can find very small comfort. And upon this matter I have no desire to differ from the ordinary mass of mankind. In truth, Shelley's creed means only a vague longing, and must be passed through some more philosophical brain before it can become a fit topic for discussion.
But the fact of this unintelligibility is by itself an explanation of much of Shelley's poetical significance. When the excellent Godwin talked about perfectibility and the ultimate triumph of truth and justice, he was in no sort of hurry about it. He was a good deal annoyed when Malthus crushed his dreams, by recalling him to certain very essential conditions of earthly life. Godwin, he said in substance, had forgotten that human beings have got to find food and standing-room on a very limited planet, and to rear children to succeed them. Remove all restraints after the fashion proposed by Godwin, and they will be very soon brought to their senses by the hard pressure of starvation, misery, and vice. Godwin made a feeble ostensible reply, but, in practice, he was content to adjourn the realisation of his hopes for an indefinite period. Reason, he reflected, might be omnipotent, but he could not deny that it would take a long time to put forth its power. He had the strongest possible objections to any of those rough and ready modes of forcing men to be reasonable which had culminated in the revolution. So he gave up the trade of philosophising, and devoted himself to historical pursuits, and the preparation of wholesome literature for the infantile mind. To Shelley no such calm abnegation of his old aims was possible. He continued to assert passionately his belief in the creed of his early youth; but it became daily more difficult to see how it was to be applied to the actual men of existence. He might hold in his poetic raptures that the dreams were the only realities, and the reality nothing but a dream; but he, like other people, was forced to become sensible to the ordinary conditions of mundane existence.
