One of the themes developed in Frankestein is the "dangerous knowledge" going beyond human limits to create a new being. Nowadays, great organizations are working secretly on developments that change human beings phisically and the way of relating with other. Secondly, we find the theme that pervates all the novel which is "monstrosity". From this concept we can say that author presents 1. A monster rejected by its unnatural and grotequesque appearance and 2. A monster that can be any person in day to day rejected by society just for looking and acting diferently.
