"A cautionary tale on science"
That was on the back of the edition that I read and when I first picked up the book. The book though turned out a bit differently than I expected in that respect...
I have of course heard of Frankenstein, most notably the scientific aspect. When I thought of Frankenstein before I thought of the deranged scientist in the lab trying to bring new life to dead bodies...
The book was much different. I wasn't taken too horribly by surprise, I had expected there to be large gaps between the 'modern' versions developed for film and the actual book. I was expected the discrepancy to be more like the difference between the modern idea of Dracula vs. the actual novel.
Frankenstein wasn't like that at all. I wasn't expecting the "It's alive!!!" line, but I was a but surprised by how it just kind of skipped over the science part. The story mostly focused on what happened after Victor created the monster. It was about all the horrible things that the monster did and how Victor was the one who actually caused it as he was responsible for the monster.
It had so little mention of science. It skipped over the gory details about how the body was put together and reanimated, and form the author's standpoint, I understand why. I wouldn't know to write that.
Instead it focused mainly on the scientist himself and how Victor overworked himself and got sick with worry. It focused on what he unleashed on the world, and Victor's fear and depression. The part where the monster spend so much time watching over that one family and learning everything he knew. It focused on how the monster vowed revenge on Victor unless he got a lover and then all the time that Victor and the monster spent chasing after each other. Notice the lack of science discussed here, it was a book about morals and the effect one has on their world, not about science.
"A cautionary tale of science" Quite false I think. More fitting would be "A cautionary tale about not becoming an obsessive idiot," "A cautionary tale about the importance of good parenting," or "A cautionary tale about how your actions can have consequences and you need to face them if you want to fix them."
