It is, indeed, the commonplace of criticism to insist on the reality which the ideal world possessed for Shelley. Other poets have illustrated thought by sensuous imagery. To Shelley, thought alone was the essential thing. A good impulse, a dream, an idea, were for him what a Centaur or a Pegasus were for common fancy. He sees in Prometheus Unbound a spirit who

Speeded hither on the sigh
Of one who gave an enemy
His plank, then plunged aside to die.

Another spirit rides on a sage's "dream with plumes of flame"; and a third tells how a poet

Will watch from dawn to gloom
The lake-reflected sun illume,
The yellow bees in the ivy-bloom,
Nor heed, nor see, what things they be;
But from these create he can
Forms more real than living man,
Nurslings of immortality.

How naturally from Shelley's imagination flowed the lines about Keats:—

All he had loved and moulded into thought
From shape and hue and odour and sweet sound
Lamented Adonais.

This was no rhetoric, no affectation of fancy. Shelley saw the immortal shapes of "Desires and Adorations" lamenting over the bier of the mortal Keats, because for him an idea or a passion was incomparably more real and more comprehensible than the things of flesh and earth, of whose existence the senses persuade us. To such a mind philosophy was not a distant world to be entered with diffident and halting feet, ever ready to retreat at the first alarm of commonsense. It was his daily habitation. He lived in it, and guided himself by its intellectual compass among the perils and wonders of life, as naturally as other men feel their way by touch. This ardent, sensitive, emotional nature, with all its gift of lyrical speech and passionate feeling, was in fact the ideal man of the Godwinian conception, who lives by reason and obeys principles. Three men in modern times have achieved a certain fame by their rigid obedience to "rational" conceptions of conduct—Thomas Day, who wrote Sandford and Merton, Bentham, and Herbert Spencer. But the erratic, fanciful Shelley was as much the enthusiastic slave of reason, as any of these three; and he seemed erratic only because to be perfectly rational is in this world the wildest form of eccentricity. He came upon Political Justice while he was still a school-boy at Eton; and his diaries show that there hardly passed a year of his life in which he omitted to re-read it. Its phraseology colours his prose; his mind was built upon it, as Milton's was upon the Bible. We hardly require his own confession to assure us of the debt. "The name of Godwin," he wrote in 1812, "has been used to excite in me feelings of reverence and admiration. I have been accustomed to consider him a luminary too dazzling for the darkness which surrounds him. From the earliest period of my knowledge of his principles, I have ardently desired to share on the footing of intimacy that intellect which I have delighted to contemplate in its emanations. Considering then, these feelings, you will not be surprised at the inconceivable emotions with which I learnt your existence and your dwelling. I had enrolled your name in the list of the honourable dead. I had felt regret that the glory of your being had passed from this earth of ours. It is not so. You still live, and I firmly believe are still planning the welfare of human kind."

The enthusiastic youth was to learn that his master's preoccupation was with concerns more sordid and more pressing than the welfare of human kind; but if close personal intercourse brought some disillusionment regarding Godwin's private character, it only deepened his intellectual influence, and confirmed Shelley's lifelong adhesion to his system. No contemporary thinker ever contested Godwin's empire over Shelley's mind; and if in later years Plato claimed an ever-growing share in his thoughts, we must remember that in several of his fundamental tenets Godwin was a Platonist without knowing it. It is only in his purely personal utterances, in the lyrics which rendered a mood or an impression, or in such fancies as the Witch of Atlas, that Shelley can escape from the obsession of Political Justice. The voice of Godwin does not disturb us in The Skylark, and it is silenced by the violent passions of The Cenci. But in all the more formal and graver utterances of Shelley's genius, from Queen Mab to Hellas, it supplies the theme and Shelley writes the variations. Queen Mab, indeed, is nothing but a fervent lad's attempt to state in verse the burden of Godwin's prose. Some passages in it (notably the lines about commerce) are a mere paraphrase or summary of pages from The Enquirer or Political Justice. In the Revolt of Islam, and still more in Prometheus Unbound, Shelley's imagination is becoming its own master. The variations are more important, more subtle, more beautiful than the theme; but still the theme is there, a precise and definite dogma for fancy to embroider. It is only in Hellas that Shelley's power of narrative (in Hassan's story), his irrepressible lyrical gift, and his passion which at length could speak in its own idiom, combine to make a masterpiece which owes to Godwin only some general ideas. If the transcript became less literal, it was not that the influence had waned. It was rather that Shelley was gaining the full mastery of his own native powers of expression. In these poems he assumes or preaches all Godwin's characteristic doctrines, perfectibility, non-resistance, anarchism, communism, the power of reason and the superiority of persuasion over force, universal benevolence, and the ascription of moral evil to the desolating influence of "positive institution."

The general agreement is so obvious that one need hardly illustrate it. What is more curious is the habit which Shelley acquired of reproducing even the minor opinions or illustrations which had struck him in his continual reading of Godwin. When Mammon advises Swellfoot the Tyrant to refresh himself with

A simple kickshaw by your Persian cook
Such as is served at the Great King's second table.
The price and pains which its ingredients cost
Might have maintained some dozen families
A winter or two—not more.
