What is a good thesis statement for oliver twist ? How can I defend that? Thanks

"The Disposables of the Victorian Society: The Darwinian
Critique of Social Treatment of Children in Victorian Era". This can be a very good
thesis statement which will give you the possibility to dwell on a number of issues of
the Victorian society with Oliver Twist as the point of departure and
reference.

To defend a statement you need engage with the
social criticism of the Victorian age particularly the dualism of morality, the
emergence of the bourgeoisie class in the industrial and their influence in the post
industrial society, prostitution and the concept of the fallen woman in the Victorian
society. You can consult Henry Meyhew's "London Labour and London Poor". It will be of
great help. As the theoretical orientation of the thesis will be Darwinian you have to
be well acquainted with the primary Darwinian theory of "Natural Selection, Sexual
Selection" and also the writings of Herbert Spencer who advocated Darwinian principles
amidst severe criticism against Darwin. Apart from that the works of Malthus, Galton 
will come handy to grasp the notion of social Darwinism and the theory of the
elimination of the weak for the proper development of the society. Donot forget to
consult the works of Gillian Beer particularly Darwin's Plots.
