Coleridge never fulfilled the promise of his early days with Wordsworth.

"He never spoke out." But it is on the lines laid down by his share in the pioneer work rather than on the lines of Wordsworth's that the second generation of Romantic poets--that of Shelley and Keats--developed.
The work of Wordsworth was conditioned by the French Revolution but it hardly embodied the revolutionary spirit.

What he conceived to be its excesses revolted him, and though he sought and sang freedom, he found it rather in the later revolt of the nationalities against the Revolution as manifested in Napoleon himself.

The spirit of the revolution, as it was understood in France and in Europe, had to wait for Shelley for its complete expression.

Freedom is the breath of his work--freedom not only from the tyranny of earthly powers, but from the tyranny of religion, expressing itself in republicanism, in atheism, and in complete emancipation from the current moral code both in conduct and in writing.
