The quality which makes Mr. Eliot almost unique as a critic is the purity of his interest in literature as literature—as art autonomous and complete. Hence the power and penetration of his essays—the fullness of his point of view—the disciplined (and thus limited) fertility of his ideas. Personal taste has its influence but is not paramount. He may or may not suffer from a romantic morality; may adhere to the tory principle in politics, and the catholic regimen in religion—or be both whig and protestant: these connexions are private and cannot much prejudice his business as a critic. This separation of interests is accomplished not by an arbitrary divorce of forms but by an honest recognition of limits. Mr. Eliot's purity of interest has been the chief taint on his reputation as both critic and poet; the accusation of sterility is common, and his very lively, even agonised mind is sometimes described as without interest in human life; whereas the right indictment will be more technical, that his choice of limits has been a little imprudent, that his essential virtue has been pushed a little beyond the extreme verge of the appropriate. (pp. 292-93)
Mr. Eliot has chosen to be a critic, and because the profession is unpopular and scantily membered, has used much of his time in emphasizing the limits of his task and in setting up a handful of principles and definitions suitable to the control of his material…. Most of his principles are ideals of form…. Most of his definitions are of distinctions and contrasts of the modifications of form. The approach is invariably technical; I mean the matters touched on are always to some degree generalised characteristics of the work in hand. No overt attack is made on the "contents" of the work directly; the marvel and permanent value of the technical method is that, when prudently and fully applied, it results in a criticism which, if its implications are taken up, provides a real and often immaculate judgment on those "contents."
