In this paper, I examine the miseducation that exclusionary punishment initiates through the significance of gender in the novel "Frankenstein." I focus on the minor character of Justine and place her story at the center, as a major account of exclusionary punishment and miseducation in literature. I highlight Shelley's story about Justine--in its philosophical and educational importance--as a tale about the significance of gender, exclusionary punishment, and miseducation. Justine's exclusionary punishment is notable in that she is a young girl punished for the crimes of a man and his murderous creation. While Frankenstein and his creature feel themselves to be monstrous at times, Justine is made to be a monster as she is excluded and punished for the crimes of a man. As a result, she nearly begins to believe herself to be monstrous. This is her miseducation as she internalizes her own oppression and is excluded from belonging to human community. Justine's story both reminds and cautions us that we make our own monsters. The making of Justine into a monster exposes exclusionary punishment as a false education--a miseducation. She is easily neglected through her youth, gender, and femininity as her story is couched within the toiling masculinity of Frankenstein and his creature. Through Justine, I claim that exclusionary punishment is miseducative as evidenced through the gendered experience of being educated to be more woman than person, more gender than human.
