This paper shows what Dickens` concept of morality of the Victorian society in A Tale of Two Cities is. Throughout the Victorian period there were long-standing anxieties about female sexuality and working-class political revolt, both of which were seen as a threat to middle-class life and property. During the first half of the nineteenth century, there was a long struggle to reform the treatment of the mentally ill, and Victorian medical psychology sought to reclaim the insane as moral subjects, subjects lacking control and self-restraint, who for various and often unknown reason had failed to internalize the moral standards of the middle class. In A Tale of Two Cities, domestic space is no longer the opposite of the asylum, no longer the private home from which the insane individual is removed and to which he or she must return. In his novel Dickens shows madness of revolution can be treated with the ideology of Victorian middle class, represented by Lucie Mannette.
