In this light it is easy to understand the curious business of criticism, and to formulate an account of what occurs when poetry dies, or falls asleep like the princess in the wood, to be awakened after two centuries by a critic’s kiss. The Elizabethan dramatists lost their potential and were judged only by their kinetic speech during the eighteenth century. They were considered coarse and bloody-minded, because there is rapine and murder in their plays. Lamb restored to them the potentiality they had lost and turned bleak rock to flowering country. Spenser had become a mere monger of allegory, until Hazlitt and Leigh Hunt reconstituted him poet by discovering for themselves and others the attitude that restores to his kinetic its lost potential speech. Writers of Wordsworth’s generation realised, at least subconsciously, that a poem is not independent of knowledge. They tried to help us by printing at the head of a poem information about the circumstances of its conception. When a poet tells us that a sonnet was composed “on Westminster Bridge” or “suggested by Mr. Westell’s views of the caves, &c. in Yorkshire,” he is trying to ease for us the task of aesthetic reproduction to which his poem is a stimulus. He is trying to ensure that we shall approach it as he did, and hear as well as the kinetic the potential speech that he values. There is a crudity about such obvious assistance, and it would be quite insufficient without the wider knowledge on which we draw unconsciously as we read. But the crudity of those pitiable scraps of proffered information is not so remarkable as the dulness of perception that can allow a man to demand of a poem that it shall itself compel him accurately to enjoy it. It is possible that much of the old poetry that now seems to us no more than direct speech was once wrapped in a veil of suggestion. It is the critic’s business to rediscover those forgotten veils and to restore to the kinetic the magic of potential speech.
