You have observed that each situation produces a certain state of mind followed by a corresponding class of works of art. This is why every new situation must produce a new state of mind, and consequently a new class of works; and therefore why the social medium of the present day, now in the course, of formation, ought to produce its own works like the social mediums that have gone before it. This is not a simple supposition based on the current of desire and of hope; it is the result of a law resting on the authority of experience and on the testimony of history. From the moment a law is established it is good for all time; the connections of things in the present, accompany connections of things in the past and in the future. Accordingly, it need not be said in these days that art is exhausted. It is true that certain schools no longer exist and can no longer be revived; that certain arts languish, and that the future upon which we are entering does not promise to furnish the aliment that these require. But art itself, which is the faculty of perceiving and expressing the leading character of objects, is as enduring as the civilization of which it is the best and earliest fruit. What its forms will be, and which of the five great arts will provide the A'ehicle of expression of future sentiment, we are not called upon to decide we have the right to affirm that new forms will arise, and an appropriate mould be found in which to cast them. We have only to open our eyes to see a change going on in the condition of men, and consequently in their minds, so profound, so universal, and so rapid that no other century has witnessed the like of it. The three causes that have formed the modern mind continue to operate with increasing efficacy. You are all aware that discoveries in the positive sciences are multiplying daily; that geology, organic chemistry, history, entire branches of physics and zoology, are contemporary productions; that the growth of experience is infinite, and the applications of discovery unlimited; that means of communication and transport, cultivation, trade, mechanical contrivances, all the elements of human power, are yearly spreading and concentrating beyond all expectation. None of you are ignorant that the political machine works smoother in the same sense; that communities, becoming more rational and humane, are watchful of internal order, protecting talent, aiding the feeble and the poor; in short, that everywhere, and in every way, man is cultivating his intellectual faculties and ameliorating his social condition. We cannot accordingly deny that men's habits, ideas and condition transform themselves, nor reject this consequence, that such renewal of minds and things brings along with it a renewal of art. The first period of this evolution gave rise to the glorious French school of 1830; it remains for us to witness the second--the field which is open to your ambition and your labor.
