Another advantage of fiction as compared with history is its completeness. The knowledge which we possess of the lives of others is the veriest fragment. We know, of course, our own lives best; but even of these, unless we are at the end of our years, we do not know the outcome. We know next well the life of an intimate--wife, child, sweetheart, friend--yet not all of that; there is much he will not tell us and much else which we cannot observe; for even he dwells with us for a brief time only, and then is gone. Of other people, we can know still less; we can observe something, we can get more from hearsay; but that is a chaos of impressions; the larger part is inference and construction, a work of the imagination, which may or may not be true. Even the biography, carefully made from all available data in the way of personal recollections, letters, and diaries, although it may approach to wholeness, remains, nevertheless, very largely a construction, a work of literary fiction. The autobiography comes still closer; yet, since it is designed for a public which cannot be expected to view it in a solidly detached fashion, it suffers from the reticence which inevitably intrudes to suppress. In fiction alone, none except artistic motives need intervene to bid silence. However, although fiction be a purely ideal world of imagined life, it is essentially the same as the real social world. For that world is also imaginary. We have direct experience of our own lives alone; the lives of others can exist for us only in our thought about them. To be sure, our daily contact with the bodies of our friends and associates gives to this thought something of the pungency of self-knowledge; yet in absence, they live for us, as the characters in a novel, only in our thought. And the majority of the people, personally unknown to us, who make up our larger social world--and for most of us this includes the great ones who are such potent factors in determining it--are real to us in the same way that Diana or Esmond are real. All historical figures belong to this world of imagination. Our friends too, as they pass out of our lives or die, and we ourselves eventually, will sink into it.
