What chapter of Mary Shelley's Frankenstein is the following quote found? "I have love in me the likes of which you can scarcely imagine and rage the likes of which you would not believe."
The quote, "I have love in me the likes of which you can scarcely imagine and rage the likes of which you would not believe," is not found in Mary Shelley's novel Frankenstein. It actually comes from Kenneth Branagh's 1994 adaptation of Shelley's novel.
While the quote is not found in the novel itself, there is one quote which is close to Branagh's adaption. This quote is found in chapter seventeen of Shelley's novel: "If I cannot inspire love, I will cause fear; and chiefly towards you my arch-enemy, because my creator, do I swear inextinguishable hatred."
While the quote from the novel does not directly speak to the love the Creature possesses, as does the Branagh quote, it does speak to the rage the Creature possesses. Given the fact that the Creature is asking Victor to make him a mate, the Creature is trying to impress upon Victor the two choices he (the Creature) has in life: inspire love or inspire fear.
This quotation is commonly misattributed to the monster in Mary Shelley's novel, but it is actually stated by this same character in director Kenneth Branagh's movie adaptation of the book. The creature asks his creator, as he does in the novel, for a companion, a female who would be created like him and, most importantly, look like him. He says that he is miserable because he is alone, and a companion could not only keep him company but also provide him with the compassion that he lacks. Humanity, including his own creator, has treated him horribly. He does, truly, long to love and be loved, and to have the kind of relationships that he has witnessed among the members of the DeLacey family. However, he promises—in different words, but in both texts (the movie and the book)—that if Victor does not give him the chance to realize a loving relationship, he will cause misery and pain to Victor and his loved ones.
