3. In one essential particular I have felt it necessary to write what I would not have spoken. I had intended to make no reference, in my University Lectures, to existing schools of Art, except in cases where it might be necessary to point out some undervalued excellence. The objects specified in the eleventh paragraph of my inaugural Lecture[3] might, I hoped, have been accomplished without reference to any works deserving of blame; but the Exhibition of the Royal Academy in the present year showed me a necessity of departing from my original intention. The task of impartial criticism[4] is now, unhappily, no longer to rescue modest skill from neglect; but to withstand the errors of insolent genius, and abate the influence of plausible mediocrity. The Exhibition of 1871 was very notable in this important particular, that it embraced some representation of the modern schools of nearly every country in Europe: and I am well assured that, looking back upon it after the excitement of that singular interest has passed away, every thoughtful judge of Art will confirm my assertion, that it contained not a single picture of accomplished merit; while it contained many that were disgraceful to Art, and some that were disgraceful to humanity. 4. It becomes, under such circumstances, my inevitable duty to speak of the existing conditions of Art with plainness enough to guard the youths whose judgments I am intrusted to form, from being misled, either by their own naturally vivid interest in what represents, however unworthily, the scenes and persons of their own day, or by the cunningly devised, and, without doubt, powerful allurements of Art which has long since confessed itself to have no other object than to allure. I have, therefore, added to the second of these Lectures such illustration of the motives and course of modern industry as naturally arose out of its subject; and shall continue in future to make similar applications; rarely indeed, permitting myself, in the Lectures actually read before the University, to introduce, subjects of instant, and therefore too exciting, interest; but completing the addresses which I prepare for publication in these, and in any other, particulars, which may render them more widely serviceable.
