Final answer:
In 'Frankenstein,' knowledge is dangerous when Victor Frankenstein's unchecked pursuit of scientific discovery creates a destructive being, and when the creature's self-awareness through learning leads to a vengeful and tragic existence.
Step-by-step explanation:
In Mary Shelley's Frankenstein, one way in which knowledge is portrayed as dangerous and destructive is through the obsession of Victor Frankenstein with creating life. He becomes consumed by his ambition to conquer death, delving into arcane sciences and alchemy. This craving for knowledge ultimately leads to the creation of a creature that causes death and destruction, reflecting the consequence of pursuing knowledge without ethical consideration.
Another manifestation of the perils of knowledge in the novel is the self-education of the creature. As the monster gains knowledge, he becomes increasingly aware of his own ostracization and the injustice he suffers. This awareness fuels his desire for revenge, leading to further devastation. The creature's education, while enlightening, brings about a painful consciousness of his situation, showing that knowledge can lead to suffering and sorrow when coupled with social isolation.
