Again we may deduce what kind of literary work would have been the result if there are given to us not only the hereditary antecedents and biographical data of an author, but a full account of his day dreams, ambitions, frailties, disillusionments, of his favourite reading, intellectual influences, love affairs and relations to his parents, relatives and friends. I do not think it would be difficult for us to deduce from the facts we have of Dante's life that he naturally would have given us a work of the nature of the _Divine Comedy_. Literature is a personal voice the source of which can be traced to the unconscious. But an author draws not only on the past in his own life, but on the past psychic history of the human family. Unconscious race memories are revived by him in his writing; his productions are influenced by most primitive ideas and emotions, though he may not be aware what they are. Yet they emerge from his pen; for the methods of thought and ways of feeling of our early ancestors still rule us. Nor is the idea of unconscious race memories idle speculation or fanciful theorising. Just as surely as we carry in ourselves the physical marks of our forefathers of which each individual has millions, so undoubtedly we must have inherited their mental and emotional characteristics. The manner and nature of the lives of those who preceded us have never been entirely eliminated from our unconscious. We have even the most bestial instincts in a rudimentary stage, and these are revived, to our surprise, not only in our dreams but in our waking thoughts and also occasionally in our conduct. We carry the whole world's past under our skins. And there is a sediment of that primitive life in many of our books, without the author being aware of the fact. Thus a deterministic influence prevails in literature. A book is not an accident. The nature of its contents depends not only on hereditary influences, nor, as Taine thought, on climate, country and environment, alone, but on the nature of the repressions the author's emotions have experienced. The impulses that created it are largely unconscious, and the only conscious traces in it are those in the art of composition. Hence the ancient idea of poetic inspiration cannot be relegated to limbo, for it plays a decided part in determining the psychical features of the work. Inspiration finds its material in the unconscious. When the writer is inspired, he is eager to express ideas and feelings that have been formed by some event, though he cannot trace their origin, for he speaks out of the soul of a buried humanity.
