A sober and scholarly- if somewhat lengthy- study of Shelley's intellectual development, in his early period during the years from 1809 to 1813. It places Shelley in his background of a Whig family, in the intellectual company of the great libertarians from Jefferson to Cobbett, from Diderot to Godwin"". This is no study of Shelley the post, but of Shelley the thinker, and according to the author this latter role has generally been underrated. A good piece of historical biographical research, with a certain timeliness in its estimate of the perennial role of radicals. But it will command only a thoughtful group of readers, chiefly intellectuals and scholars.
