Themes in Frankenstein are recurring, universal ideas that Shelley uses to explore moral and philosophical questions across the narrative.

How to meet it: Cite specific character choices or events, such as Victor’s abandonment of the creature or the De Lacey family’s rejection, alongside saying 'the creature is sad a lot'.
Teacher looks for: Explanation of how the evidence supports the theme, and what Shelley is arguing about that theme, rather than just listing events and themes.
How to meet it: After citing a plot event, add 1-2 sentences that explain what that event teaches readers about the theme, such as how Victor’s abandonment shows that creators have a duty to care for what they make.
This theme centers on Victor’s desire to push past the limits of accepted scientific practice to achieve personal glory. He pursues his goal of creating life without considering the potential consequences, or consulting mentors or loved ones about his work. Use this theme when writing essays about scientific ethics or the pitfalls of selfish ambition. Add one plot example of Victor’s ambition to your notes now.
This theme explores the duty people have to care for the things and people they bring into the world. Victor abandons his creation hours after it comes to life, refusing to take responsibility for its well-being or the harm it causes later. Use this theme when discussing the power dynamic between Victor and the creature, or comparisons to parent-child relationships. Write one sentence connecting this theme to Victor’s choice not to make the creature a companion.
This theme tracks the harm caused when people are shut out of community and connection. The creature is rejected by every human he meets, including his own creator, and his isolation leads him to act violently. Victor also chooses to isolate himself from his family to pursue his work, which contributes to his poor decision-making. Use this theme when analyzing the creature’s motivations or comparing Victor’s experience to the creature’s. Jot down one similarity between Victor’s isolation and the creature’s isolation in your notes.
This theme asks readers to consider when scientific advancement crosses ethical lines. Shelley wrote the novel during a period of rapid scientific discovery, and she uses Victor’s story to question what happens when people prioritize discovery over human well-being. Use this theme when writing essays connecting the novel to modern scientific debates, such as artificial intelligence or genetic engineering. List one modern ethical debate that this theme applies to for your next class discussion.
This theme challenges the common assumption that monstrosity is an inherent trait. The creature is physically frightening, but his violent actions are a response to rejection. Victor, by contrast, is a respected member of society, but his selfish choices cause far more harm than the creature’s. Use this theme when writing essays that compare Victor and the creature’s morality. Draft one 1-sentence argument about who you think the true monster of the novel is.
Most major plot points in Frankenstein connect to multiple themes at once. For example, Victor’s decision to abandon his creation stems from both unregulated ambition (he wanted the glory of creation without the work of care) and a failure of responsibility. Recognizing these intersections will help you write more complex, thoughtful essays and discussion responses. Identify one plot event that connects to at least two themes, and write down the connection for your essay prep. Use this before drafting any essay about the novel’s themes.
Most literature curricula identify 5 core themes: unregulated ambition, creator responsibility, alienation, limits of scientific progress, and the nature of monstrosity. Some courses may add additional themes, such as revenge or the role of nature, depending on the focus of the class.
There is no single 'most important' theme, as they all intersect to drive the novel’s narrative and moral arguments. Many courses prioritize creator responsibility and the dangers of unregulated ambition as the most central to Shelley’s core message.
Start by identifying which themes align with your essay prompt, then gather specific plot evidence to support your argument about what Shelley is saying about that theme. Use the thesis templates and outline skeletons in this guide to structure your response.
No. The theme of monstrosity applies to both the creature and Victor, as Shelley asks readers to question whether harmful actions or physical appearance make someone a monster. Victor’s selfish choices cause far more widespread harm than the creature’s actions, which frames him as a monstrous figure despite his social status.
