The curse of Rougon-Macquart is as heathen and superstitious as the curse of Ravenswood; only not so well written. But in this twilight barbaric sense the feeling of a racial fate is not irrational, and may be allowed like a hundred other half emotions that make life whole. The only essential of tragedy is that one should take it lightly. But even when the barbarian deluge rose to its highest in the madder novels of Zola (such as that called
The Human Beast ; a gross libel on beasts as well as humanity), even then the application of the hereditary idea to practice is avowedly timid and fumbling. The students of heredity are savages in this vital sense; that they stare back at marvels, but they dare not stare forward to schemes. In practice no one is mad enough to legislate or educate upon dogmas of physical inheritance; and even the language of the thing is rarely used except for special modern purposes, such as the endowment of research or the oppression of the poor.
