"Tabula Rasa" was also a prominent idea at the time- the idea that every human being is born with a clean slate. The idea that every individual is shaped purely by their upbringing This seems to be partly the case with Frankenstein's monster.
It's interesting to see how the monster is first introduced in the tale. For the first half of the book, we see him through Doctor Frankenstein's perspective. He is an object, a "thing". When things go wrong for the monster, we pity Frankenstein. He is the creator and the father, and therefore the most affected. But my previous ideas on the monster- the pity I held for Frankenstein who would be haunted forever more by this ghastly being, were turned on their head as we came to the second half of the book and the monster spoke for himself .
Frankenstein's monster is first "born" at the beginning of chapter five. He has been hinted at before, but this is the big moment. He is introduced at the same point as the horror conventions are brought in, and so we immediately sense that something is not right. Something about the way the monster is introduced to the story is somewhat disturbing. Childbirth is supposed to be a joyous occasion. But Frankenstein's monster is far from a celebrated arrival. The November rain thrashes against the window, and the candlelight is extinguishing. Frankenstein sweats with anticipation. He has worked with no rest; no freedom, on this one single project and this is his big moment. He is completely and utterly drained. Did the monster ever really have a chance? Frankenstein's standards were so high after all his hard work; he"d need little less than a miracle to satisfy his hunger. .
So the creation is abandoned, labelled a freak of nature. His watery yellow eyes opened and took one look at the world around him, and it cruelly shut him out. Frankenstein paces around his bedchambers, unable to compose his mind to sleep.
