Of what a strange nature is knowledge! It clings to the mind when it has once seized on it like a lichen on the rock.
Chapter 13 · The Creature
Context
Reflecting on his education, the Creature laments that knowledge, once gained, cannot be unlearned and has brought him suffering rather than happiness.
Analysis
The simile of lichen clinging to rock captures how knowledge becomes inseparable from the mind—lichen grows so tightly it seems part of the stone itself, impossible to scrape away without damage. The verb 'seized' makes knowledge sound like an attack, something that grabs hold violently rather than something peacefully acquired. This inverts the Enlightenment ideal that knowledge brings freedom; here it is a parasitic growth that cannot be removed.
Essay Tip
Use this to argue that *Frankenstein* questions Romantic faith in education as inherently good—the Creature's learning makes him miserable because it teaches him what he can never have, positioning knowledge as a burden that increases suffering when not accompanied by social belonging.
