The concept of the imagination as we use now is heavily indebted to the English Romantics. As is often pointed out, the distinctive feature which distinguishes them from the earlier poets is to be found in the importance which they attached to the imagination and in the special view which they held of it. Though they differ in their respective approaches, the concept of the creative imagination well serves for them as a common denominator. The aim of this paper is to examine closely the concepts of the imagination set forth in Wordsworth`s "Preface to the Edition of 1815" and Coleridge`s Biographia Literaria. Above all, the difference between Wordsworth and Coleridge in their conceptions of fancy and imagination lies in the difference between their purposes and the philosophical orientations of their theories. As Coleridge remarked in his Biographia, Wordsworth`s purpose was "to consider the influences of fancy and imagination as they are manifested in poetry, and from the different effects to conclude their diversity in kind," and, consequently, his "Preface" was "a masterly sketch of the branches with their poetic fruitage." On the other hand, Coleridge`s object was "to investigate the seminal principle, and then from the kind to deduce the degree." Wordsworth`s conception of the imagination remains at the level of the practical and empirical generalizations about the operations of the imagination in his own and other poets` poetry, and does not duly recognize the nature and function of the imagination as a mediatory power between the subjective and the objective. In short, his theory, if any theory at all, lacks the philosophical perspective, rigor, and consistency of Coleridge`s theory. As a matter of fact, Coleridge`s distinction between fancy and imagination was at once the outgrowth of his literary sensibility and the product of his struggle against the tradition of Locke and Hartley and the resultant mechanical materialism of the eighteenth century. At any rate, it is safe to say that Wordsworth and Coleridge raised the level of the discussion of the imagination higher than ever and, in doing so, went far toward elucidating the nature and feature of the creative imagination.
