A classic is more than a book which has been preserved. It must have been approved. It is a work which has received the suffrages of generations. Out of the innumerable books, of the making of which there was no end even so long ago as the days of Solomon, some few have been by the general voice of the world chosen as worthy of preservation. There are certain writings which, amid all the multitudinous distractions of practical life, amid all the changes of custom, belief, and taste, have continuously pleased and moved mankind,--and to these we give the name Classics. A book has two sorts of interest; that which is temporary, and that which is permanent. The former depends upon its relation to the time in which it is produced. In these days of magazines there is a good deal of talk about articles which are what is called timely. This means that they fall in with some popular interest of the moment. When a war breaks out in the Soudan, an account of recent explorations or travels in that region is timely, because it appeals to readers who just then are eager to increase their information concerning the scene of the disturbance. When there is general discussion of any ethical or emotional topic, the novel or the poem making that topic its theme finds instant response. Often a book of no literary merit whatever speeds forward to notoriety because it is attached, like a barnacle on the side of a ship, to some leading issue of the day. At a time when there is wide discussion of social reforms, for instance, a man might write a rubbishy romance picturing an unhuman and impossible socialism, and find the fiction spring into notoriety from its connection with the theme of popular talk and thought. Books which are really notable, too, may owe their immediate celebrity to connection with some vital topic of the day. Their hold upon later attention will depend upon their lasting merit. The permanent interest and value of a book are precisely those qualities which have been specified as making it literature. As time goes on all temporary importance fails. Nothing becomes more quickly obsolete than the thing which is merely timely. It may retain interest as a curious historic document. It will always have some value as showing what was read by large numbers at a given period; but nobody will cherish the merely timely book as literature, although in its prime it may have had the widest vogue, and may have conferred upon its author a delicious immortality lasting sometimes half his lifetime. Permanent interest gives a book permanent value, and this depends upon appeal to the permanent characteristics and emotions of humanity.
