Instinct is directly the voice of the blood. Hence it comes that Heyse's characters are deeply rooted in family and race. Like the law of Moses, they seem to teach that the soul is in the blood. They follow the voice of the blood, and to it they appeal. The undeveloped ones among them are the vigorous expression of the type of a race; the developed ones know their own nature and respect it; they accept it as it is with the feeling that it cannot be altered; they are as thoroughly guided by the instinct of their natures as are the characters of Balzac by selfishness. In order to render clear my meaning, let me quote a few passages from the "Kinder der Welt." When Edwin falls passionately in love with Toinette, his brother Balder, unknown to him, goes to her to implore her not to reject his brother, through caprice or frivolity, and throw herself away on a stranger. Her answer to his appeal is that she has but just learned and comprehended wherefore it is that in her whole life she has never been able to gain happiness. She has been informed of the secret of her origin, namely, that her unhappy mother had been betrayed into her father's power through force, and from this fact she draws the certainty that it is impossible for her to love. "My friend," says she, "I feel sure you mean well by me, you and your brother, but it would be criminal in me to persuade myself that you could help me now that everything is so clear to me, and that I am convinced that my destiny irrevocably _lies in the blood_." (The words are emphasized in the text.) This is in her eyes the last irrefutable argument. In all the characters of the book this respect for nature, almost bordering on superstition, is prominent. As it is with Toinette, so it is in the case of her opposite pole Lea. They are contrasts in every point; in this one particular alone they accord. After Lea, who has become the wife of Edwin, has learned how much power the memory of Toinette still exercises over his heart, and is overpowered with grief at the discovery, she is one day reading a book by Edwin, and for a time consoling herself by considering how much she understands of his writings that would be above the comprehension of another woman, when suddenly she flings away the book, for the thought rushes through her brain "how powerless is all comprehension of _minds_ in comparison with the blind, irrational elemental attraction of _natures_ which enslaves all freedom and infatuates the wisest." She is a woman apparently of a purely intellectual mould. A lively, ardent desire for knowledge and for clearness of mental vision has led her to Edwin; he gave her instructions in--philosophy. One would therefore suppose that she, on her part, would at this crisis have attempted to combat the magic power of the blood by an appeal to the intellectual forces which have for so long united her with Edwin. On the contrary. Far from being characterized as all mind and soul, she is beyond all else a _nature_.
