Final answer:
Mary Shelley's omission of the reanimation process in 'Frankenstein' serves to emphasize the ethical and moral dilemmas of scientific exploration, keeping the focus on character development and thematic depth rather than on implausible scientific details.
Step-by-step explanation:
Mary Shelley does not include the process of reanimation in her novel Frankenstein perhaps to maintain a sense of mystery and to focus on the themes of the unintended consequences of scientific exploration. The lack of detailed description about the scientific process allows the novel to concentrate more on the ethical and moral questions raised by creating life, as well as the impact of such actions on the characters involved, particularly Victor Frankenstein. Shelley invites readers to ponder the ambiguity and complexities of creation, responsibility, and humanity, rather than providing a clear-cut scientific explanation which might not have been plausible during her time.
