Curiosity is one of the lowest of the human faculties. You will have noticed in daily life that when people are inquisitive they nearly always have bad memories and are usually stupid at bottom. The man who begins by asking you how many brothers and sisters you have, is never a sympathetic character, and if you meet him in a year's time he will probably ask you how many brothers and sisters you have, his mouth again sagging open, his eyes still bulging from his head. It is difficult to be friends with such a man, and for two inquisitive people to be friends must be impossible. Curiosity by itself takes us a very little way, nor does it take us far into the novel--only as far as the story. If we would grasp the plot we must add intelligence and memory. Intelligence first. The intelligent novel-reader, unlike the inquisitive one who just runs his eye over a new fact, mentally picks it up. He sees it from two points of view: isolated, and related to the other facts that he has read on previous pages. Probably he does not understand it, but he does not expect to do so yet awhile. The facts in a highly organized novel (like _The Egoist_) are often of the nature of cross-correspondences and the ideal spectator cannot expect to view them properly until he is sitting up on a hill at the end. This element of surprise or mystery--the detective element as it is sometimes rather emptily called--is of great importance in a plot. It occurs through a suspension of the time-sequence; a mystery is a pocket in time, and it occurs crudely, as in "Why did the queen die?" and more subtly in half-explained gestures and words, the true meaning of which only dawns pages ahead. Mystery is essential to a plot, and cannot be appreciated without intelligence. To the curious it is just another "and then----" To appreciate a mystery, part of the mind must be left behind, brooding, while the other part goes marching on. That brings us to our second qualification: memory.
