Because Stowe saw motherhood as the "ethical and structural model for all of American life" and also believed that only women had the moral authority to save the United States from the demon of slavery, another major theme of Uncle Tom's Cabin is the moral power and sanctity of women.
因为斯托夫人认为母性是“所有美国人生活中的道德与伦理模范，” 并相信，只有女性才拥有将美国从奴隶制的恶魔手中拯救出来的道德权威； 这便是《汤姆叔叔的小屋》中表达出的另一个主题：女性的道德力量与圣洁。
