Determinism

The monster only becomes violent after being jaded twice – first by the villagers he encounters and then, more painful to the creature, by the peasants whom he grows to love. It is not the monster’s free will that causes this – his temperament is determined by past events. He was, as Shelley portrays, born “good” and became “evil” because of the life experiences he had. This fits with the theory of determinism as an agent of change and results over an individual’s free will. This is significant because the theory, in modern day, is a combination of “hard” science (physics) and philosophy – making it much like Dr. Frankenstein himself, as he is a combination of the sciences he learned in University and the philosophy he so diligently studied in advance.
