Gentlemen, if your literature, popular and other; or your art, popular and other; or your science, popular and other, is to be eagle-eyed, remember that question I to-day solemnly put to you--will you hawk at game or carrion? Shall it be only said of the thoughts of the heart of England--"Wheresoever the _carcase_ is, thither shall the eagles be gathered together"? LECTURE III. THE RELATION OF WISE ART TO WISE SCIENCE. _"The morrow after St. Valentine's," 1872._ 37. Our task to-day is to examine the relation between art and science, each governed by sophia, and becoming capable, therefore, of consistent and definable relation to each other. Between foolish art and foolish science, there may indeed be all manner of reciprocal mischievous influence; but between wise art and wise science there is essential relation, for each other's help and dignity. You observe, I hope, that I always use the term 'science,' merely as the equivalent of 'knowledge.' I take the Latin word, rather than the English, to mark that it is knowledge of constant things, not merely of passing events: but you had better lose even that distinction, and receive the word "scientia" as merely the equivalent of our English "knowledge," than fall into the opposite error of supposing that science means systematization or discovery. It is not the arrangement of new systems, nor the discovery of new facts, which constitutes a man of science; but the submission to an eternal system; and the proper grasp of facts already known. 38. And, at first, to-day, I use the word "art" only of that in which it is my special office to instruct you; graphic imitation; or, as it is commonly called, Fine art. Of course, the arts of construction,--building, carpentering, and the like, are directly dependent on many sciences, but in a manner which needs no discussion, so that we may put that part of the business out of our way. I mean by art, to-day, only imitative art; and by science, to-day, not the knowledge of general laws, but of existent facts. I do not mean by science, for instance, the knowledge that triangles with equal bases and between parallels, are equal, but the knowledge that the stars in Cassiopeia are in the form of a =W=. Now, accepting the terms 'science' and 'art' under these limitations, wise art is only the reflex or shadow of wise science. Whatever it is really desirable and honourable to know, it is also desirable and honourable to know as completely and as long as possible; therefore, to present, or re-present, in the most constant manner; and to bring again and again, not only within the thoughts, but before the eyes; describing it, not with vague words, but distinct lines, and true colours, so as to approach always as nearly as may be to the likeness of the thing itself.
