The central characters in the novel of Frankenstein can be seen to portray the value of romantic values over those that arose during the enlightenment period.
The lack of romantic values exhibited by Dr Frankenstein makes him a symbol, employed by the novel to represent the detrimental effect that the enlightenment has had on the community by discouraging essential values and valorising the dangerous pursuit of knowledge, power and glory. Newton draw support with supernatural reasons which was god to act as agents of the universe But how much more so honesty and ethics!
Whether you make it a grave or a garden of roses is not the point.
In the Age of the Enlightenment, women and the poor were seen as possessions and were held at a significantly lesser social standing than men and the rich. It's inescapable: the monster has more than just a point, in fact, there are times when it seems he's altogether in the right, and it's Victor Frankenstein who's the criminal.
However, this highly empiric nature that Walton possesses is oddly offset by the romantic ideals that he presents simultaneously, in both the format and language of his narrative. From Enlightenment to Romanticism, Realism to Symbolism, each had their own unique way of looking at life and meaning.
Grendel is still the same bloodthirsty, warlike, animalistic beast he always was. On one hand, the possibility that what we thought we could trust -- our own scientific skill, our romantic notions of what's a hero and what's a villain -- might now get ripped out from under us.
