“An invisible man is a man of power.”
Griffin treats invisibility primarily as power over other people, foreshadowing how technological possibility without restraint becomes domination and danger in the novel.
Source details
The Invisible Man, Chapter IX, “Mr. Thomas Marvel,” Project Gutenberg #5230. Griffin tells Thomas Marvel that “An invisible man is a man of power” while coercing the frightened stranger into becoming his helper; Chapter X begins immediately after this exchange. The line remains fictional character speech within Wells’s critique of Griffin’s power fantasy rather than a general endorsement of domination.
