Yet it is necessary to remember that although expression must be adequate, it must also be subordinate. It is a means and not an end, and the least suspicion of its having been put first destroys our sense of the reality of the feeling it embodies. If an actress in moments of impassioned declamation is detected arranging her draperies, her art no longer carries conviction. Nobody feeling the heart-swelling words of Queen Katharine, for instance, could while speaking them be openly concerned about the effective disposition of her petticoats. The reader of too intricate and elaborate verse, such as the French forms of triolet, rondeau, rondel, and so on, has an instinctive perception that a poet whose attention was taken up with the involved and artfully difficult versification could not have been experiencing any deep passion, no matter how strongly the verse protests that he has. Expression obviously artful instantly arouses suspicion that it has been wrought for its own sake only. Technical excellence which displays the cleverness of the artist rather than imparts the emotion which is its object, defeats its own end. A book so elaborated that we feel that the author was absorbed in perfection of expression rather than in what he had to express leaves us cold and unmoved, if it does not tire us. The messenger has usurped the attention which belonged to the message. It is not impossible that I shall offend some of you when I say that Walter Pater's "Marius the Epicurean" seems to me a typical example of this sort of book. The author has expended his energies in exquisite excesses of language; he has refined his style until it has become artfully inanimate. It is like one of the beautiful glass flowers in the Harvard Museum. It is not a living rose. It is no longer a message spoken to the heart of mankind; it is a brilliant exercise in technique. Literature, then, is genuine emotion, adequately expressed. To be genuine it must come from the imagination; and adequate expression is that which in turn reaches the imagination. If it were not that the phrase seems forbiddingly cumbersome, we might, indeed, define literature as being such writings as are able to arouse emotion by an appeal to the imagination. A sensational story, what the English call a "penny dreadful" or a "shilling shocker" according to the cost of the bundle of cheap excitement, may be an appeal to the emotions, but it aims to act upon the senses or the nerves. Its endeavor is to work by the grossest and most palpable means. It is an assault, so to say, upon the perceptions. Books of this sort have nothing to do with imagination, either in reader or writer. They would be ruled out by all the tests which we have given, since they are not sincere, not convincing, not consistent, not true to life.
