All this, I cannot help thinking, is alien to the spirit of _Wuthering Heights_, and to its greatness. It is not really any problem of heredity that we have here. Heredity is, in fact, ignored. Heathcliff's race and parentage are unknown. There is no resemblance between the good old Earnshaws, who adopted him, and their son Hindley. Hareton does not inherit Hindley's drunkenness or his cruelty. It is not through any physical consequence of his father's vices that Hareton suffers. Linton is in no physical sense the son of Heathcliff. If Catherine Linton inherits something of Catherine Earnshaw's charm and temper, it is because the younger Catherine belongs to another world; she is an inferior and more physical creature. She has nothing in her of Catherine Earnshaw's mutinous passion, the immortal and unearthly passion which made that Catherine alive and killed her. Catherine Linton's "little romance" is altogether another affair. The world of Heathcliff and Catherine Earnshaw is a world of spiritual affinities, of spiritual contacts and recoils where love begets and bears love, and hate is begotten of hate and born of shame. Even Linton Heathcliff, that "whey-faced, whining wretch", that physical degenerate, demonstrates the higher law. His weakness is begotten by his father's loathing on his mother's terror. Never was a book written with a more sublime ignoring of the physical. You only get a taste of it once in Isabella's unwholesome love for Heathcliff; that is not passion, it is sentiment, and it is thoroughly impure. And you get a far-off vision of it again in Isabella's fear of Heathcliff. Heathcliff understood her. He says of her, "'No brutality disgusted her.... I've sometimes relented, from pure lack of invention, in my experiments on what she could endure and still creep shamefully back.'" This civilized creature is nearer to the animals, there is more of the earth in her than in Catherine or in Heathcliff. They are elemental beings, if you like, but their element is fire. They are clean, as all fiery, elemental things are clean. True, their love found violent physical expression; so that M. Maeterlinck can say of them and their creator: "We feel that one must have lived for thirty years under chains of burning kisses to learn what she has learned; to dare so confidently set forth, with such minuteness, such unerring certainty, the delirium of those two lovers of _Wuthering Heights_; to mark the self-conflicting movements of the tenderness that would make suffer, and the cruelty that would make glad, the felicity that prayed for death, and the despair that clung to life, the repulsion that desired, the desire drunk with repulsion--love surcharged with hatred, hatred staggering beneath its load of love."[A] [Footnote A: _Wisdom and Destiny_, translated by Alfred Sutro.]
