“Once you stumble, Septimus wrote on the back of a postcard, human nature is on you. Holmes is on you. Their only chance was to escape, without letting Holmes knowl to Italy— anywhere, anywhere, away from Dr. Holmes” (pg. 90).
This passage shows the clear difference between Septimus and Dr. Holmes in terms of mental health. Woolf wants us to see how afraid Septimus is of the world, while also showing how out of touch people can be about mental health if they haven’t experienced it themselves. You can’t make a mistake or be weak without people putting pressure on you to be better.
