What are all the major and minor themes in the book Frankenstein?
hmmm.... well there are a lot of themes in Frankenstein (those Victorian novels are always chock full of them!) If you go to the enotes section about Frankenstein and click on themes (or just follow this link http://www.enotes.com/frankenstein/1469) that should give you the themes, but to start you off some themes include:
Alienation and loneliness (see how victor favors ambition over friends and family)
Nature versus nurture (how environment changes people)
Appearances versus reality (the creature's appearance as opposed to who he is)
Duty and responsibility
Justice versus injustice
Science versus nature
