Coleridge more than any other person was responsible for bringing about a change in the attitude of literature toward criticism. As Hazlitt puts it with his inimitable vividness, he "threw a great stone into the standing pool of criticism, which splashed some persons with the mud, but which gave a motion to the surface and a reverberation to the neighbouring echoes, which has not since subsided."[44] Whether his ideas were borrowed from the Germans or evolved in his own brain, their importance for English literature remains the same. Coleridge's service lay in asserting and reasserting such fundamental principles as that a critical standard is something quite distinct from a set of external rules; that the traditional opposition between genius and laws was based on a misconception as to the function of the critic; that all great genius necessarily worked in accordance with certain laws which it was the function of the critic to determine by a study of each particular work of art; that art, being vital and organic, assumed different shapes at different epochs of human culture; that only the spirit of poetry remained constant, while its form was molded anew by each age in accordance with the demands of its own life; that it was no more reasonable to judge Shakespeare's plays by the practice of Sophocles than to judge sculpture by the rules of painting. "O! few have there been among critics, who have followed with the eye of their imagination the imperishable yet ever wandering spirit of poetry through its various metempsychoses; or who have rejoiced with the light of clear perception at beholding with each new birth, with each rare _avatar_, the human race frame to itself a new body, by assimilating materials of nourishment out of its new circumstances, and work for itself new organs of power appropriate to the new sphere of its motion and activity."[45] This rare grasp of general principles was combined in Coleridge with poetic vision and a declamatory eloquence which enabled him to seize on the more ardent and open-minded men of letters and to determine their critical viewpoint.
