Universities now widely use ‘trigger warnings’ to advise students that something may cause them distress. This kind of alarmism even extends to classic literature such as F. Scott Fitzgerald’s novel The Great Gatsby, which is said to feature ‘gory, abusive and misogynistic violence’. Virginia Woolf’s Mrs Dalloway needs to be treated with caution because of the ‘suicidal inclinations’ in the text — a warning that would rather ruin the book if you have never read it.
