达尔文适者生存的理论在十九世纪轰动世界。它不仅是生物界的巨大突破,对神学也是个沉重的打击。它促进了公众的生物学的观念,同时也提醒作家从生物学的角度对人的生存进行观察。哈代在他的小说中就描绘了一幅幅适者生存的图画。他认为这个理论并未给人们带来希望,人类的精神幸福并没有向着更高的境界发展。 The Darwinian theory of the survival of the fittest sensationalized the world in the nineteenth century. It is not only a huge breakthrough in the biological world, but also a heavy blow to theology. It promotes public perceptions of biology, and at the same time, reminds writers to observe human existence from a biological point of view. Hardy in his novels portrays a picture of the survival of the fittest. He believes that this theory has not brought any hope to people. The spiritual happiness of mankind has not been toward a higher realm.
